I use PS CS5 and LR4 on my Mac. I also have the prior versions of both on the Mac, too. I run the SL OS.
Here's my question: I have about 500 images in .PCD and I want to batch convert them to .TIFF format. Is there a plug-in I can use or should I go to a third party app?
You'll need an older version of Photoshop, or another program to read the PCD files.
Kodak stopped supporting or updating the code for PCD many years ago.
