GPT Image 2 Tutorial for Beginners: First Image to Usable Asset

This GPT Image 2 tutorial is the path I give new teammates: one clean success, then controlled iteration—not random prompt gambling.

Step 1 — One boring success

Start with a single subject on white. Celebrate a sharp silhouette before chasing style.

Step 2 — Change one variable

Only light, or only angle, or only background. Multi-variable edits hide what worked.

Step 3 — Aspect ratios with intent

• Square for catalogs
• Vertical for stories/ads
• Wide for headers

Don’t generate square and pray for a crop.

Step 4 — Know when to switch models

If you need the same person across a set, move to Nano Banana 2 on /generate.

Practice brief (30 minutes)

1. White-background product
2. Same product, 45° angle
3. Lifestyle shelf
4. One portrait
5. Note which prompt lines mattered
