[Openexr-user] Clarification on Open EXR and Photoshop

[JK]

Hello, 

I prefer to use Photoshop for adding special effects, and would like to film 
out using OpenEXR.  (I am only adding effects to portions of the frame.)  
Question: Since Photoshop is a LDR editor (8 bits only) what will happen to the 
added effects when I convert back to OpenEXR in the 10bit floating format? Will 
they look flat, pixelated, jagged? 

I ask this question since there isn't a consensus on these lists on using the 
Photoshop plug-in for scanned film material.  It seems Cinepaint is the top 
choice.  (Converting to Linux isn't an option at this time for users such as 
myself, and After Effects doesn't have the image editing tools I need at this 
time if I wanted to go the Cineon route) 

Any suggestions? Remember, the key issue is quality, and if the 
Photoshop/OpenEXR combination can retain the quality, this is the first 
preference, but any other recommendations are welcome.   

Thank you, 

JK
