On Sharpening Images - Using ACDSee Pro 7

2014-01-22 18:24:11 GMT

Please enjoy this guest post from ACDSee User Glen Barrington. Original post can be found on

This article is designed to provide a specific practical flow of work for providing an overall, high quality base level of sharpening using ACDSee Pro 7. Because I have a compulsive need to provide detail and explanation, I have included some background information on sharpening in general. As a result, users of software other than ACDSee Pro 7 might find this text useful.

My advice regarding the various scalar levels of the controls, and how the controls are operated by the user, are specific to ACDSee Pro 7. Other software may (and probably will) require different levels and a will offer a different User Interface for the controls they provide.

A word of warning regarding the relationship between sharpening and noise. It has been my experience that people start to worry about noise too soon. One of the great ironies of digital photography is that noise can actually increase the appearance of sharpness. It is my belief that sharpness often gets ignored or compromised in the rush to eradicate any hint of noise. Finding the ideal compromise between noise and sharpness can be difficult, but I think the techniques I describe can at least lessen the pain and make having sharp images a pretty consistent experience for you.

My advise is to sharpen first without regard to noise. Then when the Base level sharpening is complete (and perhaps after detailed sharpening as well), only then attempt to find the balance between noise and sharpness. I find myself much happier with a sharp and slightly noisy photo than I am with a “creamy” and “plastic” photo with little detail.

If you do any research, you will discover that my advice is the opposite of what many pundits believe. I think their advice is built around the idea that noise is the greater problem over sharpness. I have not found that to be so from my own practice. However you decide to order your noise reduction and sharpening tasks, I think my advice will still help you achieve the maximum sharpening of your photos possible considering the other processing choices you have made.

What is Sharpness?

When discussing sharpness in photography, two words need to be understood, “resolution” and “acuity”.

Resolution is pretty much an “In Camera” feature. This is the ability of the sensor in your camera to distinguish closely spaced objects and parts of objects in your photo. You will often see in camera reviews, photos of closely spaced lines that placed in increasingly close proximity. The ability to see these lines as distinct and separate lines is a good measure of Resolution.

Acuity is the measure of how the edge between different adjacent objects transition from one object to the other. In the example of the lines above, the black bars could be considered one object, while the white spaces between them could be considered another object. If the edge of those black bars is sharp and distinct, the acuity is high. But if the transition between the bars and the white space fades from black, to shades of gray, and only then to white, then the acuity is considered low. Acuity is considered to be an aspect of the combination of your lens and the type of photo processing you do.

Clearly, resolution can be improved by the acquisition of a new camera with a better sensor. Though making sure that your camera doesn’t move or shake during the exposure can help you capture all the resolution your sensor can provide. Learn to hold your camera steady when taking photos.

However, to improve acuity, if you have a camera with interchangeable lenses, you can buy a better lens. And regardless of the quality of your lens, acuity can be improved by careful selection of photo processing techniques.

There are 3 Types of Sharpening

It is important to remember that there is no single sharpening step in post processing a photograph. There are three types of sharpening, each performed at different times of the development and editing process.

Also remember, these instructions are designed to achieve a good, overall, base level of sharpness. After this point, you may well feel the need to do additional creative detail sharpening (or softening) in specific areas of the photo. These instructions DO NOT cover that level of sharpening. In ACDSee Pro 7, and perhaps in other tools, that sort of selective detail sharpening control is relatively easy using the selection brushes and the base level instructions in this article. But the specific instructions are likely to be far more unique to each software title than is setting base level sharpness.

The third type of sharpening, Output Sharpening, is something that I find is pretty subjective, but again the generic instructions below should help you discover that sweet spot.

Base Level Sharpening - This is where you set the basic level of overall sharpness. It can include any sharpening done within the camera itself, but it also includes any sharpening you might do in the “Develop” Tab of ACDSee Pro 7 or the equivalent section of other tools.

Unless, I am shooting jpgs straight from the camera for immediate use, I prefer to do my base level sharpening during the post processing phase. Actually, even pre-sharpened jpgs, while pretty good straight from the camera, can often be improved by additional sharpening or selective softening.

Detailed Sharpening - This is where you selectively sharpen (or soften) specific areas of a photo for the maximum effect on the viewer. This used to be the exclusive domain of an external editor, but the addition of the Develop Brushes in the “Develop” tab of ACDSee Pro 7 allows the photographer to move much of this sharpening to the developing step.

This has been useful, in that one can now, not only set the base level of sharpness in the “Develop” tab in a non destructive manner, but one can also incorporate some detailed sharpening as part of the base level sharpness so that those differences in sharpness remain with the photo throughout the remaining workflow. This can be quite useful, or a total pain in the neck, depending on what you want to do with a given photo.

Output Sharpening - This type of sharpening is often forgotten by beginners, and sometimes even by experienced photographers. The reason it is needed is that, sometimes, preparing a photo for publication to the internet, a magazine, re-sizing it, or just printing, will soften an image just a bit, and the photographer will wonder why his or her photo just doesn’t look like it did in ACDSee Pro 7.

This sharpness adjustment is often subjective and according to taste, but it is absolutely essential if you want your viewers to get the full effect of a given photo. This is usually done AFTER the developed photo has been completed and any creative edits are made, and after the developed photo (which is usually raw, at least for me, but it could be a tif or jpg file format) is converted to the bit mapped distribution format, which for me, is usually an appropriately sized jpg file.

Because of this, the ACDSee Pro 7 “Edit” tab is most useful for this functionality. One doesn’t really want these distribution specific edits permanently incorporated into the developed version since future sharpening and distribution needs may not be predictable.

The Differences Between the Develop and Edit Tabs

While my comment specifically address the ACDSee Pro 7 infrastructure, the “Develop” and “Edit” model is relatively common in photographic software in general. Lightroom and a few other software titles appear to want to blur the line between the develop and edit modes, placing almost every change it can make to a photo in the “Develop” tab and leaving the “true” edit mode to external editors. There is no right or wrong in this, just subjective preferences.

In ACDSee Pro 7, the sharpening controls of “Amount”, “Radius”, “Mask”, “Detail”, and “Threshold” are the same in both modes, and function in the same way. However, the big difference is that you can undo the sharpening in the “Develop” tab at any point, but once the image is saved in the “Edit” tab, the changes are permanent and can not be undone.

Clearly, it would be wise to do as much sharpening as possible in the “Develop” tab rather than in the “Edit” tab. But I would recommend that Output sharpening be done in the “Edit” tab.

Why? For the non destructive editing that the “Develop” tab does, all changes to the photo are stored in an XML file. Each time you display a photo with an XML file, ACDSee Pro 7 reads this file and then applies these changes immediately to the image on the screen and the display copy in RAM (Not to the image saved to disk.) Clearly, if you want someone to see a photo who doesn’t have ACDSee Pro 7, that XML file is useless to them (even if they have another program that uses XML files). So creating a tif or jpg file with the changes and edits applied is the only practical way to distribute and share a photo.

How to Sharpen a Photo with ACDSee Pro 7

Before we can discuss sharpening a photo with ACDSee Pro 7, we need to have a basic understanding of the controls ACDSee uses to create and modify sharpness.

Users of other software will find this section pretty useful, I think. In my research for this article, it became obvious that sharpening controls don’t differ all that much from one piece of software to another. While the ACDSee specific advice might have marginal value to non-ACDSee users, the basic definitions and strategies will have a practical application to them.

ACDSee Pro 7 Sharpening Controls

As stated earlier in this article, the sharpening controls between the “Develop” and “Edit” tabs are essentially the same. So I have arbitrarily decided to use the sharpening controls in the “Develop” tab as a point of reference. Above, is a screen print of the ACDSee Pro 7 sharpening controls in the “Develop” tab, with them resting at their default values.

The Amount Control

The ”Amount” slider controls works in conjunction with the other control settings. However even with the other controls at the default settings, there is still some change as the slider is moved, since the default settings are just that, settings.

The amount of sharpening change occurs by adjusting the amount of contrast around the edges of objects in a given photo. When the slider is “zeroed out” (all the way to the left) no sharpening change occurs and the more you move the slider to the right, the more sharpening changes occur.

How to get comfortable with this control:

  1. Select a photo with faces, leaves (grass or tree leaves are good), and possibly with some big text such as signs.
  2. “Zero out” all the sharpening controls. In ACDSee Pro 7, you can do this by placing the cursor on a slider control, and right clicking the mouse button. This will place that control in either the “Zero”, or absolute minimum effect position. On some controls that will be all the way to the left, on at least one control, it will be in the middle.
  3. Without setting the Radius or Detail controls, move the slider to the right, notice the level of sharpening that occurs. This is the level of sharpening that can occur with the other controls “zeroed out”.
  4. Now set the Radius and Detail controls to taste, and then move the Amount control. Note that the quality of the sharpening change that occurs is different. This control is very much dependent on the parameters set, or not set, in the other controls.

The Radius Control

To successfully use the Radius control, you must first decide if the detail in the photo is fine, coarse, or somewhere in between. This decision will affect how you want to set the Radius control.

The Radius control specifies the number of pixels to adjust around the edges of each object. Higher values will work best for coarser detail while the lower values work best for the fine detail. By setting this control first, you won’t actually see any change to the photo as you set this control since you aren’t making any changes, merely setting one of the parameters for when you ultimately will move the “amount” slider control.

The Radius control for sharpening is a slider bar with a scale increment varying from 1 to 20. Unfortunately, the ACDSee Pro 7 documentation doesn’t appear to state with certainty that the increment numbers enumerate the number of pixels from the edge that are affected, though my experiments with this control tell me it is reasonably close to the absolute number of pixels affected. I believe from a day to day, operational point of view, it is safe to interpret the values as the number of pixels deep into the edge that the change will affect.

How to get comfortable with this control:

  1. Select a photo with faces, leaves (grass or tree leaves are good), and possibly with some big text such as signs.
  2. “Zero out” all the sharpening controls. In ACDSee Pro 7, you can do this by placing the cursor on a slider control, and right clicking the mouse button. This will place that control in either the “Zero”, or absolute minimum effect position. On some controls that will be all the way to the left, on at least one control, it will be in the middle.
  3. Set the Radius slider control all the way to 20. and then move the Amount Control slider to the right. You will notice that the faces and the leaves start to develop a many pixels deep border (called a “halo” by ACDSee) as you move the amount slider to the left, yet coarse detail like the big letters in the signage seem unaffected. This is because the faces and the leaves are often considered fine detail and fine detail is more susceptible to the “halo” effect.
  4. Now, move the Radius slider to between a “2” and “5”, and then repeat moving the amount slider, You will likely notice that the “halo” border that develops on the faces and leaves is almost non existent. It may even refuse to develop at all; yet there is a subtle, but real, overall sharpening effect that you can see, while the sharpening on the signs is VERY minor. If that border halo develops around the fine detail, move the radius slider control closer to “1” till it disappears. There will still be some level of sharpening as you subsequently move the Amount slider control.

Clearly the Radius control is subtle, but very important, in terms of creating the illusion of sharpness. But it is important to remember, that the edges this control “sees” aren’t always the edges you think of as important. This control affects the whole of the photo, what I call the “logical” edges including noise and texture, and not those edges a reasonable person might see as important, those I call the “rational” edges.

The Masking Control

The Masking control targets the edges of objects while ignoring the sharpening of noise and texture, which can occur with the other controls. This control attempts to emulate the sharpening masks that can be created in typical mid level editors and above. Is it as effective as a bit mapped sharpening mask? I think so. Certainly, it is much more convenient, and it does have certain advantages over an editor based sharpening mask.

First of all, it can be done in both the ”Develop” and ”Edit” tabs of ACDSee Pro 7. Since the ”Develop” tab of ACDSee Pro 7 is non destructive ”editing”, that means, if you don’t like what you have told it to do, it is easy to reverse what you have done. And in either the ”Develop” or ”Edit” tab, it doesn’t require the use of layers. If you are new enough to bit mapped editing that you are uncomfortable with layers, this offers a pretty good alternative.

I also like the easy control this tool provides over edge sharpness. At lower settings, this tool looks for edges within the body of objects, but as you move the slider more to the right, the relatively minor interior edges are ignored and greater emphasis is placed on the more delineated object edges.

You need to be careful to find the right balance for this. I’ve discovered that a slight halo begins to appear around object edges as the slider is moved to the right. In this situation, the object edges do become sharper, but that halo slightly offsets the greater sharpness the tool provides. At normal viewing magnifications, or normal viewing distances for printed material, this halo isn’t too noticeable, but if you magnify the image beyond what is considered normal, or if you expect viewers to get “up close” to a print, you will want to make sure that halo is at its minimum.

I’ve found that for foliage, and small detail objects, along with people (especially bare heads and skin) a low to medium masking value is useful. For those more coarse details, a higher masking value will work well.

In ACDSee Pro 7, if you just slide the slider to the right you won’t see any change or accommodation to the photo at all. To see the edge delineation level, you need to press the “Alt” key as you move the slider to the right. Doing this, you will quickly see how the tool identifies the various edges found within the photo.

How to get comfortable with this control:

  1. Select a photo with faces, leaves (grass or tree leaves are good), and possibly some big text such as signs.
  2. Set your Radius, amount, detail, and threshold according to taste.
  3. “Zero Out” the Masking slider. In ACDSee Pro 7, this will be at level “0”.
  4. Move the slider gradually to the right, while pressing the “Alt” key. Note that at “0”, the image is completely whitened out. As the slider moves to the right, the interior edges of objects start to appear in black. As the slider moves further to the right, the object edges gradually start to appear in white, and the interior edges grow together in black. This is a visual representation of the sharpness masking layer found in bit mapped editors.

The Detail Control

I’m not all that comfortable with the Detail control description in the ACDSee Pro 7 help file. It may be accurate from a technical perspective, but it doesn’t really give us any help in figuring out how to use it and I don’t think it is complete in its description. (Look it up if you’re curious. Getting comfortable with the help file is a GOOD thing!).

Instead, I like to think of it as providing us the ability to fine tune the effect of the combination of the Radius and Amount controls. It allows us to shift emphasis from fine to coarse within the spectrum already delimited by Radius and Amount, and it can reduce the size of the halo generated by the combination of the settings in the Radius and Amount controls. Moving the Detail slider to the right shifts sharpening emphasis to fine detail while shifting to the left emphasizes the coarser elements.

How to get comfortable with this control:

  1. Select a photo with faces, leaves (grass or tree leaves are good), and possibly with some big text such as signs.
  2. Set your Radius and Amount according to taste.
  3. “Zero Out” the Detail slider. In ACDSee Pro 7, this will be at level “50”, with an equal amount to the right in the slider as there is to the left.
  4. Zoom into a key area (from a sharpening perspective) of the photo. Depending on the photo, the zoom ratio could be as much as 200% - 300%. The goal is to see clearly the edges of the objects and those transition areas that define the edges.
  5. Move the slider to the left. Note that the image gets a tiny bit softer as does any halo that might still be there. Then move the slider to the right, note that sharpness goes up and the halo gets a bit more defined.

If you are happy with the level of sharpness and the halo generated by just using Radius and amount, there is no need to use the “Detail” Slider. Just leave it at the default setting of “50” for ACDSee Pro 7 (other software may use a different value scale, but you get the idea, I hope.)

Also, remember that the amount of change this control can make varies with the level of overall sharpening defined by the combination of the Radius control and the Amount control. This control is highly dependent on the other sharpening controls.

It is also good to remember that like the “Radius” control, the edges this control “sees” aren’t always the edges you think of as important. This control affects the whole of the photo including noise and texture, what I call the “logical” edges, and not those edges a reasonable person might see as important, those I call the “rational” edges.

Threshold Control

Threshold controls the level of difference in pixel brightness within an object’s edge must be before sharpening can occur.

So, sharpening can occur only if two adjacent (or physically close) pixels are different enough to overcome the threshold level you set. The higher values tend to sharpen strongly delineated edges and tend to ignore background noise. Lower values tend to sharpen both the edges of objects and the logical edges in their interior. As a result, at lower levels, noise also tends to get sharpened. I think the Threshold control could be reasonably described as a very mild Masking control.

ACDSee recommends that you set the threshold high enough to enhance the edges while minimizing the background noise. My experience indicates this is essentially correct. I think one gets better and more distinctive control over edge sharpening with the Masking control, however. But this tool is quite effective in adding just a mild boost to sharpness without excessively affecting noise.

The further to the LEFT the control slider resides, the more change that moving the Amount control to the RIGHT will display in terms of sharpness though at the cost of increased noise.

This control isn’t really designed, however, to register large changes in sharpening. It seems its real function is to help you find a balance between noise and sharpness without excessive softening. If I need more edge sharpening, I use the Masking control.

How to get comfortable with this control:

  1. Select a photo with faces, leaves (grass or tree leaves are good), and possibly some big text such as signs.
  2. Set your Radius and amount according to taste.
  3. “Zero Out” the Threshold slider. In ACDSee Pro 7, this will be at level “0”.
  4. Zoom into a key area (from a sharpening perspective) of the photo. Depending on the photo, the zoom ratio could be as much as 200% - 300%. The goal is to see clearly the edges of the objects and those transition areas that define the edges.
  5. Move the slider gradually to the right, note that edge sharpness goes up very slightly and a very slight “creaminess” starts to appear in the interior of the objects.

Suggested Base Level Sharpening Workflow

  • Set your base level exposure, white balance, and color controls. Don’t concern yourself with cropping, or black and white conversion if that is your goal. At this point we are interested in developing a good, well exposed and color corrected photo with which to work.
  • Decide if you are going to use the Develop tab or the Edit tab in ACDSee Pro 7. If you don’t know, or don’t have a strong reason to do otherwise, I recommend that you use the Develop tab for this step.
  • Decide if the photo requires a fine detail strategy or a coarse detail strategy. In my experience, a coarse detail strategy is relatively rare.
  • Set your Radius control. If you feel the need to go higher than, say, 4 on the radius scale, know that you are starting to pursue a medium coarse sharpening strategy and you might find detail in grass and leaves or hair to be less than you might want. I would suggest a “2” as a starting point for Radius.
  • Set the Amount control according to taste.
  • Set the Detail control. Remember, this sort of fine tunes the combination of Radius and Amount. If you already like the sharpness neighborhood that Radius and Amount put you in, you don’t need to use this control. But it’s there if you need it.
  • Set the Threshold to whatever standard you are comfortable with. I use an “8” in ACDSee as a default, and if it seems inadequate, I adjust to taste.
  • Now examine your photo. Is it sharp enough overall? Remember, this is for the overall sharpness, ignore those areas that need specific sharpness changes if you suspect getting them “right” will ruin the overall sharpness of the photo. Remember that you can always address those specific areas in your Detailed sharpening step.
  • Ask yourself, “Will adjusting one of the above mentioned controls make things better, or, are you reasonably certain that they are set properly?” If you are reasonably certain that the prior controls are reasonably well set, then you might want to move on to the Masking control or you may decide to fix the issues you see in the Detailed sharpening phase.
  • After that, we are free to address other issues such as additional noise control, B&W conversion, special effects, etc.

There you have it. This is pretty much how I sharpen my photos. I’m pretty happy with the sharpening I now get from my images and I am now going back and redoing a large number of “old” photos that I no longer consider sharp enough.


Photography Basics A-Z (Part 3)

2013-09-10 17:28:00 GMT

The third and final portion of the ABC’s of photography basics. Need a chance to catch up? Read part one and part two and you’ll be set!

Quick. Be quick with your camera! You don’t want to miss a thing. Learn the ins and outs of your specific camera so you aren’t wasting time changing settings.

Ring Light. Not every photographer uses a ring light, but there are a lot of unique ways to incorporate it into your work. For example, the right light can be used for framing, for a subtle fill, for macro, to catch interesting reflections, the options are limitless!

Shutter Speed. We have covered shutter speed numerous times on this blog. But it’s one thing that could never be talked about too much. Shutter speed is the time while the sensor is exposed to the light while the curtain is open. If we think of it as a window, it is the time while the window is open. Usually, we express the shutter’s speed in seconds or fractions of a second.

Tone can mean one of two things in colour photography: the overall lightness or darkness of an area ofa n image; or the colour of all or part of the image, usually in relation to its warmth.

Uploading your images with ACDSee has never been easier. You don’t even have to import them straight from you camera or storage device. ACDSee also makes sharing easy by uploading to social media sites such as Facebook, Flikr, and

Viewfinder. Often new photographers question if they should use the LCD screen or the viewfinder on their camera. Well, there are arguments for both: LCD - size, instant playback, easier for those who wear glasses. OR the Viewfinder - doesn’t kill the battery, less camera shake, and most DSLR’s don’t even give you the option to use the LCD as a viewfinder at all.

Workflow, another topic that we have covered a few times in this blog. There are a million ways for photographers to speed up their workflow and find a good routine. Just take your time and try them all to find out which works best for you.

X and Y… Well, those are really hard letters to think of photography terms for… check back later!

Photography Basics A-Z (Part 2)

2013-08-27 19:18:00 GMT

Picking up from part 1 here are the photography basics I through P.

Inspiration. There are a lot of places on the internet for the photographer to find inspiration, but not only that, driving around and hiking and getting out there will inspire anyone!

Jpg. The secret to using JPG files is: Set a proper White Balance, make a proper exposure. If you photograph in JPG, the file does not degrade with each subsequent opening of the file, and your files will remain sharp when printed in JPG format.

Kit Lens’ are great for beginner photographers! A kit lens is a starter lens, usually they are relatively inexpensive.

Lighting is essential to the mood of your photos. If you are not you in an area with great lighting you need to create it. Light can be enhanced by the use of reflectors, fill flash, and white balance.

Macro photography is the art of taking photos really close up pictures that reveal details that can’t be seen by the naked eye.

Photo provided by

Nature. When it comes to nature photography, the best practice is to take in the moment, breathe the fresh air, feel the air, listen to the birds, heighten your awareness of the environment and notice exactly what it is that makes the world beautiful where you are located.

Organize. Organizing your images can be one of the most time consuming and time saving tasks you can perform as a photographer. You don’t want to spend hours looking for that one picture if you can simply search the catalogue by a keyword or date.

Posing. Sometimes photographing people can be awkward for the subject. Making them feel comfortable with the situation and with themselves would be handled by good posing. There are many different posing cheat sheets all over the internet.

Check back again for part 3 - photography basics Q to Z.


Photography Basics A to Z (Part 1)

2013-08-15 23:36:00 GMT

Artistic. Also known as fine-art photography which is photography created in accordance with the vision of the artist. As a photographer, you are an artist. Be as artistic as you want!

Backlighting refers to the process of illuminating the subject from the back. As a photographer mastering backlighting is important because one, our clients have expectations and two, it creates really interesting photos.

Color is easy to take for granted, but it plays an integral part in our emotions and perception of a photograph. Knowing how to use color effectively will expand your creativity, you need to be able to spot the potential of the colors in a scene and use them in your images.

Depth of Field refers to the range of distance that appears sharp in an image. It varies depending on what you set the aperture and focusing distance. The depth of field does not change right from sharp to unsharp, but gradual transition. The larger aperture (smaller f-stop number) and closer focusing distances produce a shallower depth of field.

Exposure. In photography exposure is the amount of light absorbed during the process of taking a photograph. Enable the histogram meter, set exposure compensation so that the histogram’s pixel pile goes one way or the other: for negative compensation it should go to the left ie: dark scenes, and positive compensation to the right for light scenes.

Focus. Each SLR camera has 45 focussing points, many people use ALL the focus points, but there are those people that use the center focus point. Using the center focus point takes practice to do effectively but the advantage is that is keeps the main focus directly where you (the photographer) chooses and not the camera. So, if you like to be in control this is the way to go.

Golden Hour, also known as the magic hour, is just before and just after sunrise or sunset. We love the the lighting during the golden hours because it’s not too bright and not too dark, it’s just right! Soft golden glow, perfect if you’re taking portraits because you won’t have to worry about squinting eyes or harsh light.
