How to Use Photoshop: Step-by-Step Tutorials for Photo Editing and Digital Art
I used to think digital painting was this magical skill that required art school and natural talent. Then a friend who does concept art for video games showed me his process on a random Tuesday afternoon, just casually, like he was checking email. He used maybe four brushes. Most of the work was layering and blending, not drawing. The actual drawing skill mattered less than I assumed.
Same thing with photo editing. When I started, I thought pros used hundreds of techniques on every single image and had some secret internal checklist they ran through. So I shadowed a retoucher for a day at a commercial studio. She spent 80% of her time on three things: levels adjustments, spot healing, and dodge and burn. The rest was details you'd barely notice unless someone pointed them out. And nobody ever did.
So here's what I want to do: walk through three real projects. One photo edit, one composite, one digital painting. Not hypothetical examples designed to look good in a tutorial thumbnail. Actual workflows with the settings I use when I'm not trying to impress anyone.
Photo editing first. Find a photo where the subject looks good but the lighting is flat -- the kind of photo you'd normally delete because it's technically fine but looks boring. Open it. Ctrl+J to duplicate. Name the duplicate "edit" because honestly, naming layers takes time and I'd rather spend that time editing.
Add a Levels adjustment layer. Look at the histogram, not the image. For a typical underexposed photo taken indoors under artificial light, you'll see the data cluster toward the left side with empty space on the right where your highlights should be. Drag the white slider left to about 220-235, wherever the data trail ends. Drag the black slider right to about 15-25. The middle slider brightens or darkens midtones and I usually push it to 1.15 or so for a subtle lift that doesn't look obviously edited.
Add a Curves adjustment layer next. This is where most beginners get lost because you're looking at a diagonal line on a grid and it's not obvious what any of it means. But here's the thing: you only need two points. Place one around Input 60 Output 50 for deeper shadows that still have detail. Place another around Input 190 Output 200 for slightly lifted highlights that don't blow out. The line should curve gently. A sharp S-curve creates that horrible HDR look where every edge gets a glowing halo and the photo looks like it was processed in 2008 by someone who just discovered the clarity slider. You know the look I mean.
Now color. Add a Selective Color adjustment layer. Pick Neutrals from the dropdown because neutrals are where color casts hide. Adjust Cyan by maybe +3, Magenta by -2, Yellow by -3, Black by +2. These are starting points, not rules carved into stone. Every photo needs slightly different numbers depending on what it was shot with and what kind of light was in the room. The idea is to cool the neutrals slightly and add depth, which counteracts the flat yellow-green cast that phone cameras seem to produce no matter what lighting you're in.
If the subject is a person, zoom in to 100%. Look at the skin. Is there a color cast? Red blotches, yellow patches near the nose, that sort of thing? Add a Hue/Saturation adjustment layer and pick Reds from the dropdown. Lower the saturation slider slightly, maybe -5 to -10, and shift the hue slider by +3 toward orange. This makes skin look more natural without the obvious "I definitely edited this" oversaturation that screams amateur.
But don't stop there. The spot healing brush, shortcut J, for blemishes and stray hairs and whatever else is ruining an otherwise good portrait. Set the brush to slightly larger than what you're removing. Hardness around 50%. Just paint over the spot. Sometimes a single click samples better than a long stroke. I have no idea why. Photoshop's sampling algorithms are mysterious and occasionally vindictive.
Export. File > Export > Export As. JPEG, quality 80, convert to sRGB, embed color profile. Done. That whole edit, start to finish, takes me maybe four minutes on a photo I know. Longer when I'm experimenting.
Compositing. This is the thing people think of when they imagine Photoshop. Putting a person on a different background and making it look like they actually stood there when the photo was taken.
And I'm going to tell you something that most tutorials skip: the hardest part, by far, is the hair selection. Everything else is relatively straightforward. If you're compositing a bald person or someone with very short hair, congratulations, your life is easy and this whole section will take you ten minutes. But if your subject has long hair with flyaways and wispy strands and all that stuff, prepare to spend more time on the selection than everything else in the composite combined. It's just the nature of the tool -- fine hair against a complex background is genuinely hard to separate cleanly, even with the latest AI-assisted tools.
Open your subject photo. I use Object Selection first because it's fast and sometimes it works surprisingly well on the first try. Draw a rectangle around the subject. Photoshop guesses the edges. If the background is simple, it does a decent job. So then you refine. Click Select and Mask in the Options bar. The Refine Edge Brush on the left, second tool down, is specifically designed for hair. Paint along the hairline where individual strands meet the background. Set the Radius slider to 3-5 pixels. Set Smooth to 5, Feather to 1. Output to New Layer with Layer Mask.
Now open your background. Drag the subject layer from the first document into the second. Ctrl+T to transform, hold Shift to maintain aspect ratio, scale the subject to fit the scene. If the background is a 6000x4000 pixel beach photo and the subject was photographed against a wall, the scale needs to make visual sense. A person should be roughly a third to a quarter of the frame height for a full-body shot in a landscape.
But the compositing step that actually determines whether people believe the image is lighting matching. And most tutorials stop before this part. Look at the background. Figure out the light direction. Is the light warm like sunset or cool like overcast afternoon? Are the shadows sharp like noon sun or soft like a cloudy day? You have to answer these questions before touching any adjustment sliders.
Add a Curves adjustment layer clipped to the subject layer. Brighten the side of the subject that faces the light source. Darken the opposite side. Add a Photo Filter adjustment layer on top, also clipped. Warming Filter 85 at maybe 15-20% if the background is warm. Cooling Filter 80 if it's cool. This unifies the color temperature and it's subtle enough that even you might not notice the difference when toggling it on and off, but your brain notices, and that's what matters.
Shadows. Create a new layer below the subject. Brush tool, soft round, black, opacity 30%. Paint a shadow where the subject would cast one. Look at other shadows in the background photo and mimic their angle and softness. If the background shadows point to the right, your subject's shadow better point to the right too.
So then add a tiny amount of Gaussian Blur to the subject layer. Filter > Blur > Gaussian Blur, maybe 0.3 to 0.5 pixels. This matches the slight softness that almost all photographs have. Perfectly sharp subjects on slightly soft backgrounds scream "cut and paste." It's a tiny thing but it's the difference between a composite that works and one that looks like a bad Photoshop job from a Facebook ad.
Digital painting. New file, 3000x3000 pixels, 300 DPI. Big enough to print later. Pick the Brush tool. Right-click on the canvas for the brush picker. A hard round brush with opacity set to pressure works well with a tablet. Without a tablet, just adjust opacity manually in the Options bar.
Start by blocking in shapes. Don't try to paint details yet. Sky color on one layer. Ground or foreground on another. The main subject on a third. This value blocking approach is how I start every painting and it means you can fix one element without disturbing the others.
For a simple landscape: gradient tool for the sky, warm orange to purple for sunset. New layer, dark silhouettes for mountains or trees against the sky. New layer, the sun as a soft circle with Gaussian blur applied so it glows. New layer, clouds using a soft brush with low opacity. And then the Smudge tool, the finger icon in the toolbar, pushed sideways at 50% strength to create wispy cloud shapes. It sounds dumb to describe but works surprisingly well.
Blending modes make digital painting much easier. Set a new layer to Overlay and paint with a warm orange where light hits. Set another to Multiply and paint with a cool blue where shadows fall. I use Overlay, Multiply, and Soft Light for basically all my shading and I'm not a professional illustrator, you get the idea.
After a few of these projects, you'll notice the same patterns keep appearing. Duplicate the layer. Add an adjustment. Use a mask to control where it applies. Blend modes for lighting. The specific tool changes but the workflow is the same. Once that clicks, Photoshop stops being overwhelming and starts being genuinely useful for the things you actually want to make. And that's really the whole point.
