Batch Processing in photoshop
Batch Processing in photoshop
Use Natch Processing to automate changes to many images.
Suppose you have fifty images that you been scanned sideways
and you need to rotate, desaturate and boost the contrast of each one. You only
have make these changes to one image and photoshop will do it to all of them.
-
Open one of the images.
-
Create a new action, make the alterations you
need to make to the image (rotate, desaturate, apply curves adjustment etc.)
and stop recording. (you don’t need to assign a function key if you’re only
going to use this action for Batch processing)
-
Close the image. DO NOT SAVE CHANGES, the action
has recorded the process you want to use. If you save the changes then this
image will be processed twice when it comes to running the Batch.
-
Go to FILE > AUTOMATE > BATCH.
-
In the PLAY field, Choose your SET and then, in the ACTION field below,
Choose the action you recorded (it will probably be chosen for you already).
-
In the SOURCE menu choose ‘folder’ to apply this
action to the folder that contains the images you want to batch process or
choose ‘open images’ to apply it only to files you currently have opened in
photoshop.
-
In the DESTINATION menu you can choose ‘save and
close’ which will open the images, apply the action, overwrite save them and
then close them. If you want to keep the original images (almost always a good
idea), choose ‘Folder’ in the destination drop-down menu and then click the
“choose” button below to tell PS where to save the altered images.
Underneath, there is a range of extension option if you want
to add the date or a number to the end of the new filenames. If you don’t want
to remember the files, just leave it at the default setting.
-
Click OK
When you run the batch, it will open each image one at a
time, apply all the commands in order, save the image to the specified folder
and then close it. Depending on the size of the images and the amount of
actions you’ve applied, this can take a while and photoshop is unusable while
it’s doing it so go and make a cup of tea or something.
