The Clone Stamp tool is easy to treat as the thing you used before Generative Fill existed. That’s the wrong way round. For a crack in a wall, a stray cable or a mark on a backdrop, cloning is faster than describing what you want, costs no generative credits, and produces pixels that came from your own photograph rather than from a model.
That last point is practical rather than philosophical — generated work carries metadata that can flag it as AI-generated, which matters for some clients and some competitions. Set Sample to Current and Below, turn on Show Overlay, re-sample constantly, and keep every repair on its own layer.

The Clone Stamp Tool Is the Cheapest Retouching Tool You Own
It is easy to treat the Clone Stamp tool as the thing you used before Generative Fill existed. That’s the wrong way round. For a crack in a wall, a stray cable, a mark on a backdrop, cloning is faster than describing what you want, costs no generative credits, and produces pixels that came from your own photograph rather than from a model.
That last point has become practical rather than philosophical. Work that has been generated can be flagged as AI-generated by the metadata attached to it, and for some clients and some competitions that matters. A clean-up done with the Clone Stamp tool doesn’t raise the question at all.
What It Is Actually Good At
Repeating Texture
Brick, grass, sand, sky, fabric, wood grain. Anywhere the surrounding area contains more of the same thing, cloning it across is both quicker and more honest than generating something new.
Precise, Small Fixes
A one-centimetre repair does not need a dialogue box and three variations. It needs one sample and two strokes.
Work You Need Full Control Over
You choose exactly which pixels move where. Nothing is invented, which means nothing surprises you later at 100%.
Set It Up Properly Before the First Stroke
-
Press S to Select the Clone Stamp Tool
It shares its slot with the Pattern Stamp; make sure you have the right one.
-
Create a New Empty Layer
Never clone onto the background. This is not fussiness — a cloned repair on its own layer can be moved, masked, faded or deleted an hour later, and one baked into the original cannot.
-
Change Sample From “Current Layer” to “Current and Below”
In the options bar. This is the setting that catches everyone: on a new empty layer with the default “Current Layer”, the tool has nothing to sample and appears broken. Switch it and it works.
-
Turn On Show Overlay in Window > Clone Source
Your brush now previews the sampled area live as you hover. Aligning a repair by eye instead of guessing is the single biggest accuracy gain available here, and it is off by default.
Clone Without Leaving a Pattern
-
Alt/Option-Click to Set the Source
Pick somewhere with the same texture, the same brightness and the same direction of light as the area you’re covering.
-
Release and Paint Over the Area You Want Gone
Short strokes. Long dragged ones carry the source point along with them and smear.
-
Re-Sample Constantly
Alt/Option-click somewhere new every few strokes. Cloning from one source repeatedly is what produces the tell-tale repeated pattern that makes a retouch visible — and re-sampling is the entire fix for it.
-
Soften the Brush
Right-click on the canvas and pull hardness down. A soft edge blends the cloned patch into what surrounds it; a hard one leaves a visible boundary you’ll spend longer hiding than you saved.
Work Across Several Layers, Not One
One Layer Per Repair
Make a new layer for each separate fix. It sounds like overhead and it is the opposite — you can judge each one independently and throw away the one that didn’t work.
Wrong Position? Just Move It
Because the cloned pixels sit alone on their own layer, pressing V and nudging them into place fixes a misaligned repair in a second. This is the reason for the whole approach, and it’s impossible if everything is on one layer.
Mask the Spill
Add a layer mask and paint out anything that crossed an edge it shouldn’t have. Cheaper than undoing and re-cloning.
Merge When You’re Happy
Select the repair layers and press Cmd/Ctrl + E to merge them into a single tidy “Clone Stamp” layer once you’ve stopped adjusting.
Common Mistakes
Leaving Sample on “Current Layer”
Nothing happens and it looks like a bug. It’s a setting.
Cloning on the Background Layer
Every advantage described above disappears the moment you do this.
Sampling From One Spot
The repeated texture is obvious to everyone but the person who made it. Re-sample.
A Fully Hard Brush
Perfectly acceptable when the repair follows a hard edge, wrong almost everywhere else.
Reaching for AI on an Easy Job
Generative Fill is the right tool for a complicated background. On repeating texture it’s slower and it costs credits.
Why a Manual Tool Still Earns Its Place
The interesting question isn’t whether AI retouching is better. It’s what each approach costs you. Generative tools cost credits, a wait, and a small amount of unpredictability. The Clone Stamp tool costs attention — you have to look at the texture, notice the light direction, and decide where the good pixels are.
That attention is the part worth keeping. Photographers who have spent time cloning are better at spotting why a generated fill looks wrong, because they have had to solve the same problem by hand. The tool is not a fallback for when the AI fails; it is where the judgement comes from.
Clean Up One Image With It Today
Press S, make a new empty layer, set Sample to “Current and Below”, and turn Show Overlay on in the Clone Source panel. Download the free sample image and PSD and repair something with repeating texture around it — a crack, a cable, a mark on a wall — re-sampling every few strokes with a soft brush, on a separate layer for each fix. Then move one of those layers with V to see why the layers mattered. For retouching and layer discipline taught properly, our PRO Ultimate Guide to Non-Destructive Editing goes considerably deeper.

Clone Stamp: Common Questions
What does the Clone Stamp do?
It paints an exact copy of another part of the image. Alt/Option-click where you want to copy from, then paint where you want it to go. In the video it removes cracks and marks from a wall.
Why does nothing happen when I paint on a new layer?
Sample is set to Current Layer, and the new layer is empty. Set it to Current & Below in the options bar. All Layers works too, but you rarely want to sample layers above.
How do I see where the clone will land?
Turn on Show Overlay under Window > Clone Source. The brush then previews the sampled pixels so you can line up edges before you click.
How do I avoid an obvious repeating pattern?
Keep re-sampling. Alt/Option-click a fresh spot every few strokes instead of cloning from the same place, and lower the brush hardness so the strokes blend.
I cloned in the wrong place. Do I start over?
No. If the clone is on its own layer, press V and drag it into position, then merge with Cmd/Ctrl+E. For tricky jobs, make a new layer per stroke and merge them afterwards.
What about cloning near an edge?
Clone a little past the edge, add a layer mask and paint black over the overshoot. Cleaner than trying to stop the brush exactly on the line.
Should I use the flip options in Clone Source?
Aaron doesn’t. Flipping the source is hard to control; cloning normally on a new layer and then flipping or rotating that layer with Cmd/Ctrl+T is easier. Show Overlay is the only Clone Source setting he uses.
Why use it instead of an AI tool?
No generative credits, and no chance of the image being flagged as AI-edited. For simple clean-up like cracks on a wall it’s done in a minute.
Are the sample files free?
Yes, with a free PHLEARN account. You get the wall photo, the PSD with the clone layers and the PDF guide.
