The Batch work flow in Photoshop CS2 Adobe RAW Converter(ARC):
Create a new, empty file folder on your desktop and label it. Place CF Card from camera in CF card reader. Open the camera file that now appears on your Desktop. Select all the RAW files and copy them (drag and drop on a Mac), to the New file folder you created. Once copied, remove the CF Card and keep it safe until you are done processing those files and have stored them on a DVD or other secondary place. You want to copy them to a new desktop folder for two reasons: 1) It assures you have multiple copies 2) working through the CF card reader is very slow compared to working on files located on your desktop.
Open PSCS2, then open the Bridge (the Seashell icon in the PS top menu). It will take a moment to open. In the Right Bottom corner there is a selection of Icons that allow you to pick how the images will appear on screen. Click on the 2nd one from the left showing a rectangle with smaller squares below it. This is the film strip option. To make the filmstrip thumbnails larger or smaller, use the slider to the left of the Icon choices. Now on the left side bottom is a selector window make sure the "Show Workflow Options" square is checked.
Now, on the left top, there are two tabs, Click on "Favorites" and then on "Desktop" in the pull down menu that appears. Then in the filmstrip click/select the desktop file that you created and filled with RAW images. All the RAW files in that folder will now open in the filmstrip with the first one (or any one you select) large in the display window. Again, in the left bottom there are choices to be made like color space; what bit depth; size (I recommend using the NDs native size which will appear without a + or - after it. However, IF you want to make large prints or think you will be cropping severely you can select a + size. If you want to do larger versions this is the place to do it at the RAW stage. Then select the resolution (I leave it at 300 PPI)
To Batch process, select all similar images in your film strip, and
double click on them. A second film strip will open on the left side. Hit "Select All". When selected, hit "Synchronize" just below it. A dialog window will appear and you can select all the functions that you want to apply to that batch of images. (I leave them all selected and never open this window again). Close that window. Now begin to correct the image in the main display window and all the functions you selected in the Sync window will also be applied to all the images shown on the left side filmstrip. When done you can then individually select each of those images one at a time to further tweak it or apply other corrections without affecting all of the other images in that group. Cropping and straightening is an ex&le of such functions, because they may all need different crops.
Note: you can delete images in the left batch slide film which will make a red X appear over them, and those images will not be trashed, but will not be processed with that batch.
Now hit "Select All" once more and in the main dialog window bottom right, click on "Save XXX Images" as tiffs, to another file folder on your desktop. Repeat process for the next batch.
Once you have this down, there are ways to skip from a batch of say 3 images to 5 further down that are similar without opening everything in-between. But stick with this for now.
