Last year I timed myself doing a standard skin retouch on a portrait. Frequency separation, a curves adjustment, dodge and burn setup, a few sharpening layers, export at 2048px for web. I had done this exact sequence probably a thousand times. It took me 47 minutes, and about 38 of those minutes were pure muscle memory, the same clicks in the same order every single time.

That was the moment I finally sat down and recorded it as an action. Now the same setup takes four minutes, and I spend the other 43 minutes on the work that actually requires my eyes and judgment.

If you are still building your base layer stack by hand every time you open a new file, this article is going to change how you work.

What Photoshop Actions Are Actually Doing

An action is a recorded macro. When you hit Record in the Actions panel and start working, Photoshop logs every step as a line of instruction. When you play it back, the software executes those instructions in sequence, exactly as you recorded them.

The important thing to understand is that actions are not just shortcuts. They operate on the file state, meaning they adjust layers, apply filters, run calculations, change blending modes, and even save and close files. A well-built action can do in two seconds what would otherwise take you through fifteen separate menus.

The panel lives under Window > Actions, or you can hit Alt+F9 (Option+F9 on Mac). Every action lives inside an action set, which is just a folder. If you are not organizing your sets, you are leaving about half the value of actions on the table.

Recording Your First Useful Action (Not a Toy Example)

Open a portrait you have already retouched so you know the steps. Hit the New Action button at the bottom of the Actions panel, name it something specific like “Frequency Sep 16-bit Setup,” and put it in a set called whatever makes sense for your workflow. Hit Record.

Now perform the frequency separation manually. Duplicate your background layer twice. Name the bottom copy “Low Frequency” and the top one “High Frequency.” On the Low Frequency layer, go to Filter > Blur > Gaussian Blur and set it to 4 pixels for a standard 300dpi portrait, or 2 pixels for a 72dpi web image. On the High Frequency layer, go to Image > Apply Image. Set Layer to Low Frequency, Blending to Subtract, Scale to 2, and Offset to 128. Change that layer’s blending mode to Linear Light. Hit Stop.

That action now exists in your panel. Next portrait, you hit Play and the entire rig is built in under three seconds. Zero decisions, zero menu hunting.

Batch Processing: Where Actions Become Multipliers

A single action saves you a few minutes. Batch processing saves you hours.

Go to File > Automate > Batch. Choose your action, set the Source to a folder of images, and set the Destination to another folder where you want the outputs. Check “Override Action ‘Save As’ Commands” if your action includes a Save step, and set your file naming convention. I use a simple structure: original filename plus a suffix like “_web_2048” so I always know what I am looking at.

I regularly run batches of 80 to 120 product images this way. A set of actions handles the resize to 2000px on the long edge, a slight unsharp mask at 80% strength with a 0.8 radius, a flattened export at JPEG quality 8, and a backup save as a full-size PSD. What used to take me most of a Sunday afternoon runs overnight while I sleep.

The One Mistake That Ruins Recorded Actions

Actions record absolute values, not relative ones. If you record an action on a 300dpi file and play it back on a 72dpi file, your 4-pixel Gaussian Blur is going to look very different on the second file. This trips up nearly everyone when they are starting out.

The fix is to either record separate versions of your action calibrated to different file sizes, which is what I do, or to use the Insert Menu Item command inside your action to pause and prompt yourself to enter a value manually. You can do this by going to the Actions panel menu and choosing Insert Menu Item while you are mid-record. I have a set of actions I call “Prompt and Pause” versions that stop at any step requiring a judgment call, and I have a separate “Fully Automatic” set for tasks where the values are always the same.

I currently have over 400 custom actions organized into sets, and yes, I name them by movie genre. My sharpening actions are in a set called “Action Heroes.” My black and white conversions live in “Film Noir.” It is a terrible system for any normal person and a perfect system for me.

Making Actions Portable and Shareable

Actions are saved as .ATN files. To export a set, right-click on the set name in the Actions panel and choose Save Actions. The file will be small, usually between 10kb and 100kb depending on complexity, and it loads on any machine running Photoshop CC or later.

This is also how you build products. The action sets I sell on this site started as personal tools I built to solve specific problems in my own workflow. I recorded them, tested them across a range of file sizes and color modes, wrote documentation, and packaged them. A well-documented action set is genuinely useful to other photographers and designers, and it represents real working knowledge in a transferable form.

The single most important thing I can tell you is this: before you record any action, do the task manually one more time and write down every step. Knowing exactly what you are about to record is the difference between an action that works reliably for two years and one you have to delete and re-record next week.
