Preserving adjustment layers

[InvisSoul]

This is newb question probably. I have several files that are in RGB. I need to convert them to CMYK and keep the file layered, but I will lose some or all of the adjustment layers in the process. Is there a way to preserve the adjustment layers in the conversion??

Adjustment layers cannot be retained going from one color space to another. Curves, Leveles, Hue/Sat, et cetera cannot translate from RGB to CMYK or vice versa.

Thanks, it was kind of a rush anyways. I didn't think there was a way, but I figured I would ask anyways. You can never be too safe.

ok not come across this before so i created a layered cmyk file in photoshop, made an adjustment layer <gradient map>

then converted easily to rgb and the adjustment layer stayed put. i did tell it not to "flatten" as well. the layers were editable in the new space as well

then i did the reverse and the adjustment layers stayed.

wierd huh 8O

That is not strange. The Only adjustment layers that will not make it through a conversion are:
Hue/Saturation
Curves
Levels


The rest will convert between the two. This still is not recommended though. Converting with an adjustment layer on will give you incorrect results. To see the difference you should do a Stamp Visible (mac: apple +option+shift+E). This will make a layer that merges all the visible layers to one layer on top. Then convert to the profile you want. Now turn on and off the newly made merged layer to see the difference in results.

The same problems can happen with transparent objects in the conversion process. Try it with drop shadows and opacity changes. You will see very broad range of differences. It is always best to convert a flattened file.
