Hi all, I am curious as to what percent one generally uses with sharpening in photoshop. Sy you have a macro image at 2800 pixel width and you are bringing it down to 850 pixel JPG. I initially shoot my images in RAW then after inital editing with levels and curves I sharpen then reduce image size then sharpen again, then reduce one more time to get to 850 and sharpen a last time. But how much should I be sharpening in each phase, percentage. I usually end with using the reduce noise filter, which has a sharpen feature as well.
If you do it another way I would love to here your method and if you have a similiar method then what degree are you sharpening in each stage?
After staring at an image for over an hour the eye starts to lose objectivity.

I generally use the 'deadman's sharpening 'actions'. Also FixerLabs has an inexpensive FocusFixer which works pretty good at very low settings. And Neat Image also has sharpening, though it is quick to add halos as you get with overuse of unsharp masking. With all of these, it's applied to a sandwiched layer, the original being on top and bottom. I can punch/erase through the original from the top, punch out if I went too far in the middle, and otherwise fade down both top and sharpened middle to suit.

As for looking at it too long, that's true with anything. If you mix down a song or audio, the more you work with it, the more the ear tends to ignore. With audio, it depends on the sound system; one principal demarcation that between headphones or not. With photos, it depends on the monitor gamma, and if one is satisfied it matches fairly well with the prints you are getting. So with a photo, you keep the original. You work with version B, or C, or whatever. You might think it came out just right. You go for some coffee. Look out the window. Look back at the computer and say to yourself- what . . was I thinking?

Hi all! I'm start photoshop work with color noise reduction:
1. convert image to LAB color model.
2. Gausan Blur A & B layer (radius from 5 to 10). Depends on noise level.
3. Convert to RGB
After that I start reduce size to required value (usual to 750px for bigger side). Original is 3800px:
1. Unsharp photo with 50%
2. Reduce size to 1500px
3. Unsharp photo with 30%
4. Reduce size to 750px
5. Uhsharp with 30%
Finish.
All of this step's I wrote as Action script for batch processing for my many photos. Action Script is realy saved my Time!
