How to Craft the Best AI Space Prompts

Writing a good prompt is a skill. Certain methods help you get better results from the AI. Follow these practices to create clear instructions that produce stunning images.

Use a Clear Structure

A helpful structure for prompts is Subject → Context → Style. Start with the main subject of your image. Then, describe the environment or background. Finish with the artistic style. This order helps the AI prioritize the elements correctly.

Add Specific Details

Include 4 to 6 descriptive words that add visual information. These are "high-signal" details. Words for lighting, mood, color, camera angle, and material help the AI understand your vision. Specifics lead to a more accurate image.

Specify Composition and Framing

Tell the AI how to frame the shot. Use terms like "close-up," "wide shot," or "aerial view." You can also specify the viewpoint, such as "low angle" or "bird's-eye view." This gives you more control over the final composition.

Use Negative Prompts

A negative prompt tells the AI what to exclude. Phrases like "no watermark," "no text," or "no extra limbs" can prevent common errors. This cleans up the final image and removes unwanted artifacts.

Iterate One Change at a Time

Your first image may not be perfect. After you generate an image, adjust one part of your prompt. You can change a color, the lighting, or the background. Small, single changes help you refine the image toward your goal.

Be Succinct but Informative

Long prompts are not always better. Focus on words that have the most impact on the image. Remove filler words. A concise and informative prompt is often more effective than a long, confusing one.
