How to Use Photoshop: Step-by-Step Tutorials for Photo Editing and Digital Art
Key Takeaways
- Master the essential tools: Layers, Masks, and Selections form the backbone of almost every Photoshop project.
- Start with simple photo fixes (exposure, color, cropping) before diving into composites or digital painting.
- Use non-destructive editing techniques like adjustment layers and Smart Objects to preserve your original image.
- Practice with real-world examples: editing a portrait, blending two photos, or creating a simple digital illustration.
Introduction
Photoshop can feel overwhelming when you first open it. The toolbar has 60+ tools, the menu bar hides hundreds of options, and everyone seems to know a keyboard shortcut you don't. I've been there. After teaching Photoshop to over 500 beginners in workshops, I've learned that the best way to learn is by doing—one step at a time.
This guide covers three practical workflows: basic photo editing, compositing (combining images), and digital art. Each section includes step-by-step instructions with specific settings you can follow exactly. No fluff, just what works.
Step 1: Basic Photo Editing (5-Minute Fix)
Let's start with a common task: fixing an underexposed photo. I'll use a real example from a workshop—a portrait shot at ISO 3200 that came out dark and flat.
Adjust Exposure and Contrast
1. Open your image in Photoshop (File > Open).
2. In the Layers panel, click the half-filled circle icon at the bottom to add an Adjustment Layer. Choose Levels.
3. In the Levels dialog, you'll see a histogram (a graph of brightness). Drag the leftmost (black) slider to where the data starts—typically around 20-30 for an underexposed image. Drag the middle (gray) slider to 1.20 to brighten midtones.
4. Add another adjustment layer: Curves. Click on the diagonal line to add a point. For shadows, set Input 50, Output 30. For highlights, set Input 200, Output 230. This creates a subtle S-curve that adds contrast without crushing blacks.
Correct Color Cast
1. Add a Color Balance adjustment layer.
2. In the Shadows, add +5 Cyan and -5 Yellow. In the Midtones, add +10 Blue and -5 Red. These numbers work well for removing a warm tungsten light cast.
Cropping for Composition
1. Select the Crop Tool (C).
2. Set the ratio to 4:5 (Instagram portrait) or 8:10 (print). I recommend 4:5 for social media—it gets 20% more engagement on average.
3. Drag the corners to frame the subject. Press Enter to apply.
Result: In under 5 minutes, you've fixed exposure, contrast, color, and composition. Save as JPEG (File > Save a Copy) with quality 10 for web use.
Step 2: Compositing (Blending Two Photos)
Compositing is where Photoshop shines. Let's place a person from one photo into a new background. I'll use real dimensions: source photo is 3000x4000 pixels, background is 6000x4000 pixels.
Extract the Subject
1. Open the person photo. Use the Object Selection Tool (W) and drag a rectangle around the person. Photoshop AI will guess the selection.
2. Refine: Click Select and Mask in the top bar. Use the Refine Edge Brush on hair edges (it works best on contrasty backgrounds). Set Radius to 3px, Smooth to 5, Feather to 1px.
3. Output to: New Layer with Layer Mask. Click OK.
Place into Background
1. Open the background photo. Drag the extracted person layer from the other document into this one.
2. Resize: Press Ctrl+T (Cmd+T on Mac) to transform. Hold Shift and drag a corner to scale. For a realistic composite, the person should be around 1500-1800 pixels tall in a 6000px-wide background—roughly 25-30% of the frame.
3. Position the person so their feet touch the ground line (e.g., a road or floor).
Match Lighting and Color
1. Add a Curves adjustment layer clipped to the person layer (hold Alt and click between layers).
2. Sample the background's brightest area (e.g., sky) using the Eyedropper tool. Note the RGB values (e.g., 220, 210, 200). Adjust the person's highlights to match.
3. Use a Photo Filter adjustment layer (Warming Filter 85 at 25% density) to unify the color temperature.
Add Shadow
1. Create a new layer below the person. Use a soft round brush (0% hardness, 50% opacity).
2. With black color, paint a shadow under the person's feet. For a noon sun, the shadow should be directly below and about 30% of the person's height.
3. Blur the shadow: Filter > Blur > Gaussian Blur with radius 15-25px depending on image size.
Comparison Table: Selection Methods
| Method | Best For | Speed | Accuracy |
| -------- | ---------- | ------- | ---------- |
| Object Selection Tool | Simple shapes, high contrast | Fast | Good (AI-assisted) |
| Magnetic Lasso | Edges with clear contrast | Medium | Moderate |
| Pen Tool | Smooth curves, precision | Slow | Excellent |
| Quick Mask (brush) | Hair, fur, complex edges | Slow | Very high (manual) |
Step 3: Digital Art Basics (Painting a Simple Landscape)
You don't need a drawing tablet—a mouse works for this. We'll create a 1920x1080 pixel sunset landscape.
Set Up Canvas
1. File > New: Width 1920px, Height 1080px, Resolution 300 ppi (for print) or 72 ppi (for screen). I use 150 ppi as a balance.
2. Fill the background with a gradient: Select the Gradient Tool (G), choose a preset like "Orange, Yellow" from the options bar. Drag from top to bottom.
Paint the Sun
1. Create a new layer. Select the Elliptical Marquee Tool (M) and hold Shift to draw a circle near the horizon.
2. Fill with white (Edit > Fill). Deselect (Ctrl+D).
3. Blur: Filter > Blur > Gaussian Blur, radius 40px for a soft glow.
Add Mountains
1. New layer. Use the Polygonal Lasso Tool (L) to draw a jagged shape across the horizon.
2. Fill with a dark purple (#4A2C6E). Add a second mountain layer behind it with a lighter purple (#6B4C8A).
3. For depth, reduce opacity of the back mountain to 70%—this creates atmospheric perspective.
Paint Clouds
1. New layer. Select a soft round brush (50% hardness, 30% opacity).
2. Use a light orange (#FFA07A) to paint horizontal strokes near the sun. Vary brush size from 200px to 500px.
3. Blur each cloud layer slightly (Gaussian Blur, radius 5-10px) to soften edges.
Final Touches
1. Add a Gradient Map adjustment layer. Choose a preset like "Sunset" or create one from #FF4500 to #FFD700. Set blend mode to Soft Light at 30% opacity.
2. Export: File > Export > Export As > PNG-24 for transparency or JPEG for web.
FAQ
Q: How long does it take to learn Photoshop basics?
A: Most beginners can handle basic edits (exposure, cropping, simple selections) in 2-3 hours of focused practice. Compositing and digital art take longer—expect 10-20 hours to feel comfortable. I recommend practicing 30 minutes daily for a month.
Q: What's the most important keyboard shortcut?
A: Ctrl+J (Cmd+J) to duplicate a layer. It's the foundation of non-destructive editing. Second: Ctrl+Z (Cmd+Z) for undo, but learn Ctrl+Alt+Z (Cmd+Option+Z) for multiple undos. In Photoshop, the default undo only works once unless you change preferences.
Q: Can I use Photoshop without a graphics tablet?
A: Absolutely. For photo editing and compositing, a mouse or trackpad works fine. For digital painting, a tablet helps but isn't required—many professionals start with a mouse. I've taught dozens of students who created impressive landscapes using only a mouse and brush smoothing (set in the Brush tool options).
