Adjustments vs Adjustment Layers in Photoshop

Adjustments vs Adjustment Layers in Photoshop

Photoshop offers the same corrections in two places. Image → Adjustments gives you Brightness/Contrast, Levels, Curves, Hue/Saturation and the rest. Layer → New Adjustment Layer gives you an almost identical list.

They are not duplicates. One writes into the layer you are on; the other creates a separate layer that sits above and can be changed, masked, faded, or deleted at any point. Knowing which is which — and the one trick that makes the first kind safe — is the difference between an editable file and one you have to start over.

What Each One Does

Adjustments (Image → Adjustments) apply directly to the selected layer. Raise the brightness, click OK, and those pixels are now brighter. There is no separate object in the Layers panel and no way to reopen the dialog and change your mind.

Adjustment layers (Layer → New Adjustment Layer) create their own layer above the image. The pixels beneath are untouched; the layer describes a change that is calculated live. It can be hidden, re-edited, faded, masked, reordered, or thrown away.

Make Adjustments Safe With a Smart Object

The straight Adjustments menu is not a bad workflow — it just needs one step first.

Before applying anything, go to Layer → Smart Objects → Convert to Smart Object and check for the badge on the thumbnail.

Now run Image → Adjustments → Brightness/Contrast as before. Instead of baking in, it appears beneath the layer as a Smart Filter. You can toggle its visibility, and double-clicking its name reopens the dialog with your settings intact.

That single step converts a destructive edit into a reversible one. If you use the Adjustments menu at all, use it on a Smart Object.

Creating Adjustment Layers

Three routes to the same thing:

Layer → New Adjustment Layer, which offers a dialog with naming and a clipping mask option. The half-filled circle icon at the bottom of the Layers panel, which is quicker. Or the Adjustments panel under Window → Adjustments, which is quickest of all.

Edit one at any time by double-clicking its thumbnail or selecting it and looking at the Properties panel.

The Three Things Only Adjustment Layers Give You

A Layer Mask

The big one. Every adjustment layer arrives with a mask, so the correction can be limited to part of the image.

Select the mask, use Edit → Fill → Black to hide the effect everywhere, then paint white where you want it — brightening only a face, for instance, rather than the whole frame.

A straight adjustment has no mask and no way to add one. It is all or nothing.

Opacity

Adjustment layers have an opacity slider, so the strength of any correction can be dialed back after the fact.

This is particularly useful with Gradient Map, which is one of the best color-toning tools in Photoshop and always arrives far too strong. Add one, click Reverse in Properties if it looks inverted — it usually does — pick a gradient, then drop the layer opacity to something like 20 or 30 percent. What was an overwhelming effect becomes a subtle grade.

Stacking and Reordering

Adjustment layers stack. Several can sit above one image, each independently toggleable, maskable and adjustable, and dragging them into a different order changes the result.

The Catch: They Affect Everything Below

An adjustment layer applies to every layer beneath it, not just the one you had selected.

Add a text layer under a Gradient Map and the type gets recolored along with the photograph. Add it under a Brightness/Contrast layer and the type gets brightened too. This surprises people, and it is the most common source of confusion with adjustment layers.

Clip It to One Layer

The fix is a clipping mask. Hold Alt or Option and move your cursor to the boundary between the adjustment layer and the one below — the cursor becomes a box with a downward arrow. Click.

The adjustment layer indents and now affects only the layer directly beneath it. Everything else in the document is left alone.

Clip each adjustment you want restricted. On any file with several elements — type, graphics, multiple images — this is what keeps corrections where you intend them.

The New Adjustment Layer dialog also has a Use Previous Layer to Create Clipping Mask checkbox, which does the same thing at creation time.

Which to Use

Adjustment layers for most work. Masking, opacity, stacking and clipping cover nearly everything, and none of it touches your pixels.

Adjustments on a Smart Object when you want a correction bound to one specific layer and do not need a mask — it keeps the Layers panel tidier on a complex file.

Adjustments on a normal layer essentially never. That is the only combination with no way back.

Summary

Image → Adjustments writes into the layer. Layer → New Adjustment Layer creates a separate, editable one with a mask.

If you use the Adjustments menu, convert to a Smart Object first so it becomes a re-editable Smart Filter. If you use adjustment layers, remember they affect everything below them, and Alt-click between layers to clip one where that is not what you want.
