As a follow up to reading Ricks very helpful introduction Tutorial on processingimages in Adobe Camera which is here
I went to Adobe and found a ‘manual’ which gives you all the detail you need to take advantage of the processing tools ACR offers. This gives you all the details about all the tools and what they do and how to use them. It is long winded but very detailed so even a klutz like me can read it and understand how it works.
Here is a teaser to get you to go have a look see if you are new to processing and have access to Adobe Camera .
Sharpen photos in Camera
The controls on the Detail tab adjust edge definition in the image. The Adjustment Brush tool and Graduated Filter tool use the Radius, Detail, and Masking values when local is applied.
Use the Apply To option in the Camera preferences to specify whether is applied to all images or just to previews.
To open preferences from within Camera , click the Open Preferences Dialog button in the toolbar.
Zoom -- the preview image to at least 100%.
In the Detail tab, adjust any of these controls:
Amount-- Adjusts edge definition. Increase the Amount value to increase . A value of zero (0) turns off . In general, set Amount to a lower value for cleaner images. The adjustment is a variation of Unsharp Mask, which locates pixels that differ from surrounding pixels based on the threshold you specify and increases the pixels’ contrast by the amount you specify. When opening a camera image file, the Camera plug-in calculates the threshold to use based on camera model, , and compensation.
Radius - Adjusts the size of the details that is applied to. Photos with very fine details may need a lower setting. Photos with larger details may be able to use a larger radius. Using too large a radius generally results in unnatural-looking results.
Detail- Adjusts how much high-frequency information is sharpened in the image and how much the process emphasizes edges. Lower settings primarily sharpen edges to remove blurring. Higher values are useful for making the textures in the image more pronounced.
Masking -- Controls an edge mask. With a setting of zero (0), everything in the image receives the same amount of . With a setting of 100, is mostly restricted to those areas near the strongest edges. Press Alt (Windows) or Option (Mac OS) while dragging this slider to see the areas to be sharpened (white) versus the areas masked out (black).
(Optional) To apply Camera 6 to images that were edited in a previous version of Camera , click the Update To Current Process (2010) button in the lower-right corner of the image preview.
