How to Make AI Image Tools Generate More Human-Like Images

With the continuous development of AI Image generation technology, more and more creators are hoping to obtain more realistic and human-like images, whether it's for character design, social media, or artistic creation. They prefer high-realism portrait generation features compared to cartoon or other artistic style images. Realistic-style images not only better meet a wider range of commercial needs but also look more realistic visually, increasing the credibility of the images. Today, let's take Picool.ai as an example to delve deeper into how to use AI to generate more human-like images.

Choosing the Right Style and Model

The models on different AI platforms vary greatly. Some are good at 2D anime illustrations, while others excel at realistic portraits. If you want to generate more human-like images, you need to do the following:

Choose a realistic model: In Picool.ai, when selecting an image generation style, you can prioritize choosing styles related to realistic styles.

Clearly tell the AI: When writing the prompt, clearly tell the AI that you want to set the image style as realistic or human-style. If the final generated image does not meet your requirements, you can also choose the Image to Image function in AI Image to make more subtle adjustments to your prompt, making the generated image more aligned with your needs.

Comparison examples:

Prompt: “a beautiful woman” → may generate images with a tendency towards cartoon or virtual styles.

Prompt: "a photorealistic portrait of a young woman, 8k, DSLR lens" → more lifelike

Prompts should be specific, especially facial details

When generating portraits, AI Image often fails to produce high-quality results due to vague descriptions, so the more specific your prompts, the better the image quality generated by AI Image tools.

Facial detail prompts:

Keen eyes, detailed eyelashes, natural lips, defined jawline

Skin Texture:

Realistic skin texture, pores visible, smooth lighting

Photography Effects:

DSLR, 50mm lens, cinematic lighting, depth of field

Practical Tips:

If you want to generate very beautiful and highly realistic portrait images, you can refer to photographic terms in the prompt, such as studio lighting, bokeh background.

Lighting and Environment Settings

Light is one of the key factors affecting the generation of images by AI Image tools. Natural light, as well as various soft lights and indoor lighting effects, can make the images generated by AI Image tools more similar to photographic works.

Recommended lighting effects: warm sunlight, studio scene, rim light

Avoid using terms: cyberpunk style, sci-fi style, these two prompt words will cause the content generated by AI Image to become more sci-fi or artistic.

Make good use of negative prompt words

Common issues with AI-generated character images: incorrect number of fingers on characters, asymmetrical faces, and overly rough skin texture that looks like plastic.

In Picool.ai, these errors can be reduced by using negative prompt words.

Common negative prompt words:

blurry, deformed hands, extra fingers, asymmetrical face, cartoonish

Effectiveness: After using these prompts, the images generated by the AI Image tool will become cleaner and reduce strange details.

Improving the Resolution of AI Image Tool Generated Images and Post-Processing Optimization

Even if the images generated by AI Image are already sufficiently realistic, if we can further process the post-processing optimization of AI Image, it can also add a touch of perfection to the image effect.

High-definition magnification: Avoid jagged edges or blurriness in the image.

Partial Repair: Fine-tune the details of the eyes and mouths of characters in AI Image-generated images, and so on.

Skin Retouching: You can moderately smooth the AI Image, but retain the pores and texture of the image

Find the AI Image Feature

Enter your prompt words

Waiting a few seconds will bring the image (if the generated portrait image is not satisfactory, you can adjust the prompt and try several times)

Common Issues When Using AI Image to Generate Images

When using the AI Image tool, the following issues may occur:

Error 1: The prompt is too vague

Solution: Use more adjectives to modify nouns, or add more image detail prompts.

Error 2: Ignoring light description

Lack of light and shadow settings will make the image look rather stiff,

Solution: Modify using various different light adjectives.

Error 3: Use the image generation feature only once

Solution: Generate multiple times, gradually adjust your prompt, and if the text-to-image feature doesn't work in Picool, you can also choose the Image to Image feature

Summary: Realistic images are not achieved overnight

When using the AI Image feature to generate portraits, it's not completed with just a simple prompt. You need to select a clear photorealistic model and have more precise control over your prompts. If possible, you can also use more detailed prompts to control the lighting effects of the image, making it look more realistic.
