5 Effective Tips On Creating Realistic Images With AI Image Generators

1. Use Better Prompts

Instead of saying "a person," try "a middle-aged woman with short gray hair and green eyes, wearing a red sweater." The more details you provide, the more realistic and accurate your image will be.

2. Use Reference Images

Many AI generators allow you to upload reference images. This can help the AI understand the style, composition, or specific elements you're looking for. For example, if you're creating a landscape, upload a photo with the lighting and atmosphere you want to capture.

3. Test Negative Prompts

Negative prompts tell the AI what not to include. This can be particularly useful for avoiding common AI quirks. For instance, adding "deformed hands" to your negative prompt can help ensure more realistic hand renderings.

4. Adjust Technical Parameters

Most AI tools offer settings like guidance scale, sampling steps, or seed values. Start with the defaults, then tweak:

• Increase sampling steps (for instance: from 20 to 50) for more detail.
• Lower the guidance scale (for instance: from 7 to 5) for more creative interpretations.
• Save seed values of images you like to recreate similar styles.

5. Post-Process With Traditional Tools

AI-generated images often benefit from some touch ups. Use photo editing software to:

• Adjust contrast and color balance for a more natural look.
• Blend multiple AI generations for the perfect composition.
• Fix small imperfections or oddities the AI might have created.

Remember, creating realistic AI images is a skill that improves with practice. Don't be afraid to test and try different styles with your prompts and model settings.
