comment: Note that in Adobe Bridge for CS2 you have to create the 'Save' action and the Batch command is located under Tools > Photoshop. Also it works rather silently, hard to tell at first.

comment: This worked like a charm! I followed these instructions to assist one of my users. This saved her hours of opening and "saving as". My user is using Photoshop CS on an OSX PowerMac G5. Thanks so much!!!!

Instructions for batch converting raw images

1. In the Photoshop CS File Browser, double click a RAW file and adjust shadows, contrast etc to suit.
2. Hold down the alt key and the OK changes to Update. Click update to save the settings and close the Camera Raw dialogue.
3. If other images are similar, select this first one, then the others and right-click them. Choose Apply RAW Settings and choose the first image name from the bottom of the drop list to apply those settings to all. Then go back & make custom settings if needed or process different pictures in separate styles.
4. Click the actions tab on the history pallete to create a very simple action to convert with. First open one of the files (you won't need the open in the action). Then from the action menu (triangle in upper-right) select New Action and name it simply as "save" or maybe "save-jpeg" "save-tif".
5. Back to the open image, save as jpeg, tiff, nef or whatever you like. Close the file.
6. Click the square stop button on the bottom of the action pallete next to the red recording indicator to finish recording this very simple action.
7. Back in the File Browser highlight all the images you want to batch, right-click & select batch.
8. See the screen shot above for the settings you need: select the "save" action you just made and check "Suppress File Open Options Dialogue"
9. Choose the output folder. I wish it was smart enough to just put them in the same folder as the original files, this is a real pain.
10. Click OK and it will run. You are done.
