Batch Processing with Adobe Photoshop

For those of you who don’t already know, Photoshop has these nifty little features called Actions. Now, these actions can be used for many things, including the creation of beautiful and eye catching effects, maximizing your productivity, or simply to carry out the tedious and mundane tasks that you just doesn’t feel like doing.

I only just discovered the wonder of Batch Processing. I’m dedicated and detail oriented, but sitting in front of the computer adjusting the Hue/Saturation for the countless number of photos taken at my son’s first birthday was simply out of the question. I did find a more than happy solution in Batch Processing.

When you’re creating an action you need it to do one thing: Something. In my case, I needed to change the Hue/Saturation for 75+ images from blue to my “trademark” teal. Maybe you need an action for a different purpose, but humor me and tell yourself, “Hey, I need to make my image the same color as hers!” Next, you’ll need something to work on. Get a small image, like an icon, preferably the one I’m using for this tutorial.

Now go to Window – Actions and make sure it is checked. If it is, you should see a tab in the Layers Palette labeled, of course, Actions.

Click on the arrow button to expand the Actions menu and choose “new set.” This creates a folder for the action you create (you don’t necessarily need the folder, it simply helps with organization.)

Return to the Actions menu and choose “New Action.” Before you begin to record an action you need to decide the steps you’ll need to take and the order in which you’ll need to take them. This is a pretty simple action and soon you will be able to do this is your sleep.

Now for the recording part. There will be a small circle icon between the square and the triangle at the bottom of the palette that you will need to click. Now Photoshop will record everything you do until the end of the Action. If you have an error, simply stop the Action by pushing the square icon and go back to your last step taken.

For our action, the first thing we need to do is change the Mode of the image to RGB, since .gif files are saved in Index mode which don’t take too kindly to colorization. So with the action recording, go to Image – Mode – RGB.

Next, we’ll have to strip the image of it’s current color to make adding our (my) own color easier to apply, so go to Image – Adjustment – Desaturate.

You should see a naked grey image and so we need to add some color. Make sure your action is still recording and go to Image – Adjustments – Hue/Saturation. It helps to have the settings for color saved in a .ahu (Hue/Saturation) file so all you have to do is click Load and select Teal.ahu. If you don’t have a file saved you can simply use the sliders.

Woo, we’ve now SunBlinded the icon! All that’s left to do now is save it for the web. Is your action still recording? Good. Go to File – Save For The Web and set your file type and optimization settings. I use the standard GIF settings, but whatever floats your boat, dude. Select your destination directory and save. If your Actions palette looks like this:

Stop recording and say “Yay, I made an action!” because you’re finished. Now to put your newly born action into… ahem… action, we’ll do a Batch Process. What this will do is take all the images in a specified directory and apply whatever changes were recorded in the action. Just for the sake of the tutorial, create a directory and drop some images into it, or just duplicate one that you already have.

Begin by going to File -Automate – Batch and make sure the name of the Action Set you just made is in the first dropdown list and the name of the Action is in the second. Set the third dropdown box (next to Source) to Folder and use the Choose button to find your duplicated or created folder of images. For destination, you can leave it set to it’s default “None” to have the action applied and saved in the source folder, or save the “actionized” images into a separate folder. Click OK once you have everything set to your liking..

Now sit back and watch your images color themselves because you’re using Actions and Batch Processing to do your dirty work
