Can anyone make a suggestion – I have been doing fairly simple manipulations on my images. I use adjustment layers with blending modes of either Luminosity or Color depending on the purpose of the adjustment. And, I am careful not to create contradictory layers – all of the tonal adjustment layers darken the image and I only lighten by using a mask on the adjustment layer. Some of my images flattened without any change. But occasionally there is a strong tonal shift when flattened – portions of the images will arbitrarily lighten. I have tried merging similar blending mode layers first, updating the histogram, messing with the cache…. Any ideas? Thanx.
I sometimes get a similar effect when I flatten images whereby some layer
shunt themselves a pixel to the right or the left, thus mis-aligning everything.
It’s completely unpredictable and impossible to know when it will happen.
I’ve discovered I can avoid it by using "Merge Down" instead of "Flatten
Image".
It might work in your case too.
it only happens when the layers are not in normal mode
and merge down gives the same problem
may have something to do with each layer being a different blend mode?? I have not seen the SHIFTING of pixels you describe
The flattening/image shift problem does not have to do with merging the layers or flattening in any variety of orders, and not with the blending modes – I experimented with all of these things. It seems to have to do with viewing the image at less then 100% while making adjustments to layers – specifically tonal adjustments. When flattening my images a noticable tonal shift occurs. The shift between layered and flattened images does not occur when viewed at 100%, but for larger files I can only view the entire image at around 25%. The image looks great with the adjustments I make at 25%, but when flattened the true appearance (that shown at 100%) reveals itself and it looks nothing like the preview at 25%. Zooming in to 100% is basically like working in the dark since it only shows a samll piece of the image. Thank you for all of your suggestions. Any experience with this would be appreciated.
Have you tried opening your file in two windows at the same time?? you can leave one at print size another at actual pixels, that way you can see the effects at different zooms as you work
I often do this when sharpening
Not a bad idea – I like that, but it still means I can’t see the actual adjustments I make to the full image. Still some guesswork involved. And yes, I’m using a calibrated Cinema Display. Do you think that the fact I’m working off of a laptop (MacBook Pro with maxed RAM) could be causing problems? It is good, but slow on these large files.
