3. Base Image Generation – Obtaining the initial material from the AI.
4. Analysis and Edit Planning – Identifying parts that require improvement.
5. Basic Adjustments – Correcting obvious flaws.
6. Advanced Adjustments – Applying more sophisticated post-processing techniques.
7. Finalization – Fine-tuning details and preparing for specific use.

You can adapt this process framework according to the specific needs of your project and your own working style.

Basic Post-processing Techniques for AI-Generated Images

Let's start with an overview of basic techniques that anyone working with AI-generated images should master. These techniques do not require advanced skills and can be performed even in simpler graphic editors.

Color Correction and Toning

AI generators can sometimes produce images with unnatural or undesirable color tones. Basic color correction includes:

• Adjusting brightness and contrast – Balancing the overall lightness and darkness of the image.
• Color balance correction – Removing unwanted color casts.
• Saturation adjustment – Enhancing or reducing the intensity of colors.
• Toning – Applying a uniform color tone to unify the image's atmosphere.

These adjustments can dramatically improve the visual impression of an AI-generated image and help achieve the desired atmosphere.

Removing Unwanted Artifacts

A common problem with AI-generated images is various artifacts – unnatural textures, distorted objects, or nonsensical details. To remove them, you can use:

• Cloning tools – To replace problematic areas.
• Retouching brushes – For subtle corrections of surface imperfections.
• Smudge tools – To soften unnatural transitions.
• Noise reduction tools – To smooth out grainy textures.

Careful removal of artifacts is often time-consuming, but significantly increases the professionalism of the result.

Adjusting Composition and Perspective

AI generators may not always create the ideal composition. Basic composition adjustments include:

• Cropping – Removing excess parts and focusing on the main subject.
• Transformation – Changing scale, rotation, or perspective correction.
• Rearranging elements – Moving objects for better visual balance.
• Filling empty spaces – Expanding the canvas and drawing missing parts.

Proper composition is the foundation of effective visual communication, so it's worth paying sufficient attention to it.

Enhancing Sharpness and Detail

AI-generated images can suffer from insufficient sharpness or missing details. This problem can be addressed by:

• Selective sharpening – Applying sharpness only to key areas.
• Increasing local contrast – To emphasize textures and details.
• Applying detail overlays – Adding textures to increase realism.
• Using resolution enhancement tools – To improve the overall image quality.

These techniques can significantly improve the readability and persuasiveness of your image.

Advanced Post-processing Techniques

For those who want to elevate their AI-generated images to a truly professional level, there are several advanced techniques. These approaches require deeper knowledge of graphic editors and more experience, but the results are worth it.

Composite Workflow

Instead of relying on a single AI-generated image, you can combine different elements from multiple generations or external sources:

• Layering multiple AI generations – Combining the best parts from different iterations.
• Masking and blending – Sophisticated combination of elements with smooth transitions.
• Integrating external elements – Adding photos, textures, or hand-drawn details.
• Creating complex scenes – Assembling intricate compositions from individual elements.

The composite approach gives you maximum control over every aspect of the final image and allows you to overcome many limitations of AI generation.

Detail Enhancement and Texture Crafting

To achieve photorealistic results or highly detailed illustrations, it is crucial to focus on textures and details:

• Frequency separation – Separately processing details and color areas.
• Dodging and burning – Manually modeling lights and shadows.
• Texture overlays – Applying specialized textures to increase realism.
• Detail painting – Manually drawing fine details.

These techniques require patience and precision, but they can transform an average AI output into an impressive work of art.

Lighting and Atmospheric Effects

Lighting has a fundamental impact on the mood and atmosphere of an image. Advanced adjustments include:

• Light painting – Manually adding and modeling light sources.
• Atmospheric effects – Adding fog, smoke, dust, or light rays.
• Color gradients – Creating sophisticated color transitions.
• Light accents – Adding reflections, glows, or lighting effects.

Proper lighting can dramatically change the tone of the image and give it a cinematic quality.

Stylization and Artistic Filters

Sometimes you want to push an AI-generated image towards a specific artistic style or visual aesthetic:

• Emulation of traditional media – Imitating painting, drawing, or graphic techniques.
• Complex color grading – Advanced color adjustments inspired by film post-production.
• Applying texture overlays – Adding paper, canvas, or other surface structures.
• Selective stylization – Applying filters only to selected parts of the image.

Stylization techniques allow you to create a unique visual signature and differentiate your work from standard AI outputs.

Specialized Workflows for Different Project Types

Different types of projects require different approaches to post-processing. Let's look at a few specialized workflows.

Conceptual Illustrations and Concept Art

When creating conceptual illustrations, it is crucial to maintain readability and clear communication of the design:

1. Generate several variants of the basic concept.
2. Select the most promising variant and correct proportions and perspective.
