Batch Processing

Batch Processing

Q1:	What is batch processing?
A1:	If you have created an action and you'd like to apply that action to a folder full of images, use the Batch command (File>Automate). This command lets you choose an action and select a folder to which you'd like to apply that action. Note: Unless you want the action to overwrite your existing files (which you may), pay attention to the options under Destinationyou may want to select an existing folder (or click the Make New Folder button) for the images to be saved into after the action has run.
Q2:	How do I convert a bunch of files from TIFF to JPEG? I have a bunch of images that I need to change from TIFF files to JPEG. Is there a way to create a macro or something to do that?
A2:	You can create an action that will change the format (as well as resize, apply filters, change modes, etc.), and then run it as a batch. First, click the Create New Action icon in the Actions palette, click Record in the resulting dialog, and then choose File>Save As and select JPEG in the Save As dialog. Click the Stop Recording button, and then choose your action in the Batch function. This command (File>Automate>Batch) lets you run an action on a folder of images (see the following question for additional help on how to apply a Batch action). Another option is to use File>Scripts>Image Processor, as one of its functions is changing file format (without having to record an action first).
Q3:	Why does my Batch command keep saving the same file name? I have recorded an action that includes saving as a JPEG. But when I run it as a batch, I only get one file because all the files get saved with the same name . How can I get around that?
A3:	This happens when you record the step File>Save As and select a specific file namethat file name becomes part of the action. To get around this, in the Batch function, make the Destination a folder, then choose Override Action "Save As" Commands and select a file-naming protocol. When you click OK, Batch will run as a generic action that can be applied regardless of the file name.
