“Deadline…today!” If, like me, you are familiar with that sentence then you will definitely appreciate this month’s column about batch processing images in Photoshop. The batch processing concept is simple: your “steps” to one image are “recorded” and then “played” again on any number of targeted images. (Those of you familiar with actions might have noticed the evident similarity; this is because Photoshop utilizes actions to accomplish its batch processing.) How effective is batch processing with Photoshop? Quite effective actually. Although the batch process takes a little while to set up, the results are astounding, saving loads of time.

 

















 
                     Convert 113 RGB JPEGs to CMYK PICTs? No problem!

Now, let’s see how it works:

1. Place all images to be batched in one folder (which we will call “2b-batched” for 
    explanation sake).

2. Figure out what exactly you want to do with the images. (Crop, convert format or 
    color, etc.)

3. Break up the process. Basically, what you should always keep in mind is that the 
    computer is very stupid. You can not assume that, just because you know what to 
    do, the computer does too. So, a simple image resize consists of the following steps:

     1. Open file
     2. Choose “Image Size..” from under the “Image” menu
     3. Type in pre-saved numbers
     4. Save
     5. Close

This makes much more sense to a computer.

4. Record an action with your resulting steps (you can override “Open file” and then 
    activate the Override Action “Open” Commands check box in the batch process 
    window).

5. Select “Batch…” from the “Automate” submenu of the “File” menu.

 































  i) The name of the set where your action is saved.
 ii) The name of the action to be executed.
iii) The location of the folder to be batched (in this case call “2b-batched” folder)
 iv) The location of where you want the resulting images to be saved.
  v) Error control.

With the above steps finished, all you have to do is select the “Ok” button and watch the computer do your work for you.

A word of advice: never under any circumstance show this to your boss or you will end up fired :-)
