Hello:
How do you batch process/convert RAW files to JPEG using Photoshop CS3? All images were shot under 2 lighting conditions, daylight and flash. The JPEG files will be corrected and uploaded to Costco for printing.Thanks very much, Pompey

When you open either type of image in Camera Raw, do they need correction for White Balance or are they acceptable? If your camera white balance was on auto, and your images when viewed in Camera Raw are acceptable, then you should be able to place all of the RAW files in the same folder, create a small Action, and go File>Automate>Batch.
If you need to chnage the White Balance to Flash because the images which were taken by flash are too blue / cool, you could separate the two types of images into two separate folders eack of which will be treated differently so you would run a separate batch command on each folder.
Regards, Murray

Hi Pompey... Welcome to RetouchPRO.

To batch process RAW in Photoshop takes a little setup, but once the foundation is in place the workflow is greatly simplified.

This tutorial is CS2 based, but there is some good info:

This CS-based four-part Jeff Schewe authored tutorial here is pretty meaty, too:

I hope these get you started or at least help connect a few dots.

Thanks very much for the solutions you offered; Ill check them out.
