You can take a picture on a Mac in two main ways: using the camera (webcam) or by capturing your screen. Below are the simplest methods.

1. Take a picture with your Mac’s camera (Photo Booth)

This is what you use for a selfie or a “normal” photo with the built‑in camera.

  1. Open Photo Booth
    • Click Finder in the Dock.
    • Go to Applications.
    • Double‑click Photo Booth. The camera light next to your webcam should turn on, and you’ll see yourself on screen.
  2. Choose your photo style
    • At the bottom left, pick single photo or 4-photo burst (a strip of four shots).
    • Optional: click Effects to add fun filters or backgrounds.
  3. Take the picture
    • Click the big red camera button at the bottom center.
    • A 3‑second countdown plays, then the Mac takes the photo.
  4. Find or share the photo
    • Thumbnails of your shots appear at the bottom of the Photo Booth window.
    • Drag a photo to the Desktop or another folder, or use the Share button to send via Mail, Messages, or add to Photos.

2. Take a picture of your screen (screenshot)

If by “picture” you mean “capture what’s on my screen,” use these shortcuts:

  • Whole screen:
    Press Command (⌘) + Shift + 3.
    → A file is saved to your Desktop (by default) as a .png.

  • Selected area:

    1. Press Command (⌘) + Shift + 4.
    2. Your cursor turns into a crosshair.
    3. Click and drag to select the area you want, then release.

  • More options (Screenshot toolbar):

    1. Press Command (⌘) + Shift + 5.
    2. At the bottom of the screen you’ll see tools for:
      • Capture entire screen
      • Capture selected window
      • Capture selected portion
      • Record screen
    3. Choose what you want, then click Capture.

Tip: After capturing, a small thumbnail may appear in the corner; click it quickly to crop, annotate, or share without hunting for the file.

3. Super quick “how‑to” recap

  • For a camera photo of yourself :
    • Open Photo Booth → red camera button.
  • For a picture of your screen :
    • Whole screen: ⌘ + Shift + 3.
    • Part of screen: ⌘ + Shift + 4.
    • Toolbar with all options: ⌘ + Shift + 5.
