I found I produced too many halos when I started using PS2 on files from a D2X. I think I have learned a bit since. Now I find images from my 800E need even more careful processing than those from a D3S or D3X; it is an ongoing learning curve. If I write down what I do, I may learn a lot from comments experts make!
Trying to keep it simple I use just PS6.
RAW image opened in ACR 7.1 Exposure and contrast roughly adjusted if necessary. Normally Clarity 0, though it might be raised later for some images. As far as possible I keep the other controls at 0, but depending on the subject, lighting conditions and difference in colour sensitivity of the hunam eye and the camera, I alter anything or everything else. My standard sharpening is:
- Amount 30 - 60, - Radius 0.5, - Detail 100, - Masking 0, - Luminance, variable 0 - 40 depending on the ISO of the image - usually 30.
I ensure there is no granularity or mottling in low detail areas and no halos on high contrast edges, by altering the Luminance, and for high ISO images adding up to 30 Masking. The image is at 300% for this examination and adjustment. I want no artifacts added at this stage.
Very rarely I will increase the Sharpening Amount above 40 for images that are not going to be enlarged much.
Images are filed like this as .dng for future manipulation. Images for use are sharpened in Photoshop as required after other processing. Typically for say twigs against a white sky:
- Amount 100%, - Radius 0.3 px.
The Amount control I adjust at 200% or 300% image magnification to ensure no artifacts are produced.
