Anyone who had tried to do Batch Processing in Photoshop is familiar with the Batch automation . . . File>Automate>Batch
It's pretty convenient, but I've always had trouble with the "Override Action Save As" part of it . . . I never know if I need to include a Save in the Action or not . . . I always had to sort that out every time I used it . . .
Then someone told be about the
Image Processor script. File>Scripts>Image Processor
This script is much better because you can save versions of your files as .psd, .jpeg and .tiff simultaniously if you wish. I sometimes use this because I have finished a set of images I need to upload for commercial printing (.jpeg) -I also wish to archive (.tiff) . . . I can always open the .tiff in photoshop if it needs more work . . . anyway, with the Image Processor I can generate a .jpeg and a .tiff at the same time for as many images as I have in the set.
Another scenario would be to save as .tiff for archive, and .jpeg for posting on Chimper, or in preparation for web gallery generation (are you reading this Doc?). In the File Type step, just enter the size in pixel dimentions you want your final jpegs to be (check off Resize to Fit first). You'd also check .tiff to save as that type as well . . . (never use the LZW compression. If you want a smaller file size just use a #12 jpeg. Uncompressed .tiffs are 100% of your image data which is the whole point of using .tiffs nowadays)
All you have to do is follow the steps in this control panel to assign an Action to be applied to the images you process as well . . .
-There's a new Action in the Downloads section to Watermark your images.
-E!
