Photoshop CS5: variations in rendering of inner-shadows (depending on zoom level)

different zoom levels are causing huge variations in rendering of inner-shadows on my system.
turning off opengl or changing acceleration modes doesn't fix the problem.

Usually View > 100% is the reliable preview size when it comes to the effects of interacting Layers, Blend Modes, Layer Styles, ...
Alternatively you could try setting Cache Levels to 1.

Hi!
Thanks for your reply!

Right. Layer-blend-modes, transparent objects combined with effects cause a whole lot of interaction between layers - even more difficult to calculate when using cached fragments.

If I think of the code powering photoshop, it's hard to believe that things like this are working as good as the do!

I still wanted to see, if there's a simple answer that might solve this "kind of problem".
Disabling cache solves the problem - with the expected loss of performance.

Thanks again!
Michael.

A lot of it depends on the image in question - if it's really noisy, the downsampling (zooming out) will make almost any manipulation a bit misleading. Worst case is a halftone image: at 100% it's black and white, but if you zoom out you have gray values.

Hi Chris!
Yes, you are right.
In my case not these excpected downsampling results, but layer-blend-modes caused the problem - completely invisible shapes while zommed out, appeared in 100% view. changing blend modes to just 'normal' also helped to get around this difference.
Thank you!
Michael.
