Understanding ChatGPT Images
How image creation, editing, references, and limitations work.
Find the subject first. Then name the setting, color choices, and details you would check against the brief.
What you will be able to do
- Choose generation or editing from a real brief.
- Identify the parts of an output that require human review.
The core principle
ChatGPT supports creating images from written requests and editing uploaded or generated images. It also supports text and transparent-background requests. Those capabilities are not promises that every instruction will be met. A prompt is a brief; an output is a candidate.
In this course, start with a small still-life brief rather than a complicated campaign. Decide what success means before generating: one cup, a clear focal point, and no text. If you already have a useful composition, try an edit instead of rebuilding it. The learning goal is to distinguish the task from the result and to notice unintended changes.
Course practice: keep a brief, candidate, and review note together. Write what worked, what missed the brief, and your next specific instruction. This hub prepares prompts and tracks practice; generation happens separately in ChatGPT.
- Choose generation or editing from a real brief.
- Write one sentence stating the intended use and main subject.
- The review note separates an observed result from a requested change.
A workflow to try
- Write one sentence stating the intended use and main subject.
- Choose create for a new scene or edit for an existing image.
- List three visible conditions the candidate must satisfy.
- Review the output against the conditions and record one next change.
See the difference in the brief
Course-authored example. Use it as an experiment, then judge the image you actually get.
Make a nice portrait.
Create an editorial portrait for a professional profile. Use the attached portrait as the identity reference. Frame head and shoulders against a neutral grey background with soft light from camera-left. Preserve recognizable facial features and natural skin texture. No text.
The revised prompt states purpose, reference role, framing, lighting, and what to preserve.
Create a tabletop still life with one cup and no text. Inspect it against three criteria. Then ask for a single background change while keeping the composition. Save both prompts and your review notes.
How to judge your result
- The chosen task matches the brief.
- You can point to the main subject and describe one mismatch.
- The review note separates an observed result from a requested change.
Common mistakes to watch for
- Calling the first candidate finished because it looks attractive.
- Confusing image analysis with image generation.
- Using a private reference without permission.
