CS5 losing levels ajustment

Feb 27, 2013 9:50 PM

I am losing my levels adjustment when converting from PSD to any other format here is the jist of it...

 

levels layer...........taking the contrast way up

saturation layer....saturation up

invert function

find edges layer

duplicate layer

background layer

 

At the point that I convert to jpg or another file type I lose the levels adjustment.

Also flatten image or merge visible layers causes the same problem.

 

I can supply a file if needed

 

Any ideas???


Thanks in advance

Mike

    I think you are another victim of the popular assumption that Photoshop’s preview at anything other than 100% is reliable.

    In many/most cases this is irrelevant but with especially noisy/contrasty images for example this can make a huge difference.

    So please use View > 100% on the layered File then flatten – does the appearance change?

     

    Ina any case: Would you mind posting some screenshots?

    In Photoshop preview sizes other than Actual Pixels for a layered image can entail interpolated Layers and Masks which can affect the preview.

    conroy points out that setting a Cache Level of 1 in the Performance Preferences would alleviate the issue.

    (But this could have performance drawbacks depending on the images you work on.)

    Christoph, no, the particular colour distortion you showed is not prevented by Cache Levels 1.

    With the pure black/white noise image and the Curves Layer it seems to remove the color cast, though.

    That's good. Cache Levels 1 is more effective than I thought, then.

     

    I still got the colour cast of your example, but my graphics card and driver (supplied by Apple) are quite old and do have problems with 16-bit mode when Cache Levels is 1.

    And a relaunch of Ps is now resulting in the colour cast not being evident in 8-bit mode. Cache Levels 1 definitely is more useful than I thought.

    So I learned something new today.

    I was under the impression that a change of Cache Levels would affect subsequently opened/created documents without a relaunch of Ps. That's not the case for me (today, at least). A relaunch of Ps is necessary to affect a change on my computer. Now the colour cast does not occur in both 8-bit and 16-bit modes.
