Practical Test Sequence: 7 Steps to Better Results

Follow these steps to find the right model and settings without running unnecessary tests or overprocessing your image.

Optional: If you're a paid user, you can download all AI models in advance to save time and streamline your workflow.

  • 1. Start with the right model.

    Use the flowchart above to choose a starting point. Real-Photo v3 is suited to photographic fidelity, More-Detail GAN v3 emphasizes detail and sharpness, AIGCsmooth v3 is designed for AI-generated images, and Smooth Diff v2 is worth trying for smoother images, illustrations, and line art.

  • 2. Compare a second model when needed.

    Use the same source image, output scale, and comparable settings for a fair comparison. Test a second model when the first result does not meet your goal or when another model has a clear advantage for that image type. Focus on meaningful differences in detail, noise, texture, and naturalness instead of generating multiple results without a clear purpose.

  • 3. Adjust Strength to avoid overprocessing.

    If the result looks too sharp, smooth, or artificial, try reducing Strength if available. If basic image quality still needs improvement, consider checking 2-pass processing or compare another model. Keep the result that looks most natural for your image.

  • 4. Use Face Restoration only when it helps.

    For portraits and old photo scans with unclear facial details, compare results with Face Restoration on and off. Keep it enabled only when it improves facial clarity without unwanted changes to facial features, proportions, or skin texture.

  • 5. Use the minimum processing needed.

    Decide whether you actually need more pixels before choosing an upscale factor.

    If the original dimensions are sufficient and you only need to reduce noise or improve clarity, start with x1.

    For low-quality images with significant blur, noise, or compression artifacts, try restoring the image at x1 first, then evaluate whether upscaling is necessary.

    If you need a larger output, start with x2 rather than jumping straight to the maximum scale.

  • 6. Check the final output, then scale up your workflow.

    Evaluate the result at its intended viewing or output size—not only in Preview or at 400% zoom.

    For print, consider the final pixel dimensions, print size, and required DPI; for web or further editing, check the exported image at its actual use size.

  • 7. Batch Process Only After Testing.

    Aiarty supports batch export with shared settings, as well as per-image adjustments when needed. Before processing a batch, test your chosen model and settings on a representative image. Once you're satisfied with the results, apply them to similar images to streamline your workflow. However, images with different lighting, ISO levels, noise levels, or cropping may require individual adjustments.

Choose by Image Type

Birds & Wildlife

Bird and wildlife photos often contain intricate details such as feathers, fur, eyes, and fine patterns. High-ISO shooting, low light, or cropping can make these details look noisy or soft. The challenge is to improve clarity without making natural textures look artificial.

Start Settings

  • Upscale: Choose x1 if the original dimensions are sufficient and you only want to improve image quality. Choose x2 if you need a larger image.

  • Strength: Start with the default value, then adjust it based on the result. Lower it if feathers, fur, or other fine textures look exaggerated.

View software settings >

Other Settings That May Make a Difference

  • Enable 2-Pass Processing: This adds an extra x1 enhancement pass and may help refine noisy, grainy, or slightly blurry images. Compare the result carefully, as extra processing can also make details look too sharp or intense.

  • Adjust Max Tile Size: For large wildlife photos, check the Max Tile Size setting if processing speed or GPU memory is a concern. Smaller tiles use less GPU memory but may take longer to process. Larger tiles require more memory and can produce smoother results with fewer visible tile seams. Choose a setting that suits your hardware and image size.

Why

Real-Photo v3 is designed for realistic photographs, with an emphasis on fidelity to the original image and natural-looking detail. It is a sensible starting point for high-resolution wildlife photos where reducing noise matters more than adding pronounced new textures.

If the bird's feathers still look soft or lack definition, compare the result with More-Detail GAN v3. This model is designed to restore clearer, sharper details and may bring out intricate feather patterns more strongly.

Watch for

Inspect the bird's eye, beak, head, and wing feathers at 100% zoom. Look for reduced grain in the background and darker areas, while checking that individual feathers remain distinguishable. Pay attention to fine edges and color transitions as well: they should look clear without appearing harsh, smeared, or artificially reconstructed.

If It Looks Wrong

  • Noise remains visible: Compare More-Detail GAN v3 with the same upscale setting and inspect both results at the same zoom level.

  • Feathers look too smooth or lose definition: Try More-Detail GAN v3 to see whether it preserves finer patterns more effectively.

  • Fine details look exaggerated or artificial: Lower Strength. If you are using 2-Pass Processing, turn off 2-Pass and process the image again.

Choose by Image Problem

Blur and Soft Focus

A photo may look soft when the subject is slightly out of focus, fine details are not well defined, or the original image has limited sharpness. This can make important features, such as eyes, hair, and clothing textures, appear less distinct.

Aiarty Image Enhancer can help improve perceived clarity and bring out visible details in suitable images. The best settings depend on the type and severity of blur, as well as how much detail remains in the original.

Start Settings

  • Upscale: x1 if you only want to improve clarity without enlarging the image. Choose a higher upscale factor if you also need more pixels for a larger display or print.

  • Strength: Start with the default value of 1, then lower it if edges or textures look too sharp or artificial.

View software settings >

Optional

  • If the image still lacks definition, try enabling 2-Pass Processing. Compare the result with standard processing to see whether the extra enhancement improves detail without introducing unwanted artifacts.

  • For old portrait photos, you can also try testing the results with Face Restoration enabled.

Why

More-Detail GAN v3 emphasizes detail and sharpness, making it a useful starting point for images with soft edges or textures. It may help make features such as eyes, hair, and clothing patterns more distinct.

If the result looks too sharp or changes the original texture, compare Real-Photo v3. Its emphasis on natural-looking photographic detail may provide a more restrained result for some images.

Watch for

Inspect the eyes, eyelashes, hair strands, and edges of the clothing pattern at 100% zoom. Check whether these areas look more defined without developing bright outlines, exaggerated textures, or unnatural transitions.

Also compare the subject's facial features with the original. Improved clarity should not come at the expense of a recognizable, natural-looking face.

If It Looks Wrong

  • The image still looks soft: Compare Real-Photo v3 and More-Detail GAN v3 at the same upscale factor and inspect the same areas. If the source is heavily blurred, the improvement may be limited.

  • Edges look harsh or details appear artificial: Lower Strength. If you enabled 2-Pass Processing, turn it off and process the image again.

  • The face looks different from the original: Compare the facial features carefully and avoid settings that produce convincing-looking but inaccurate details.

Choose by Desired Result

Keep the Original Look

Best for: Realistic photos where natural textures, recognizable features, and fidelity to the original matter more than strong sharpening or pronounced detail enhancement.

If an enhanced image looks too sharp, too textured, or noticeably different from the original, try the following adjustments.

  • Start with Real-Photo v3. It is designed for realistic photographs and emphasizes natural-looking detail. If the result still looks too soft or changes important textures, compare it with another suitable model using the same output settings.

  • Lower Strength if the effect is too strong. A lower value may help preserve the original texture and appearance. Compare the result with the original to find a balance between improved clarity and natural-looking detail.

  • Choose Fidelity for Face Restoration when resemblance is the priority. If Rebuild produces facial features that look different from the original, try Fidelity and compare the results. Check that the restored face remains recognizable.

  • Turn off 2-Pass Processing if the image looks overprocessed. An additional enhancement pass may make details more pronounced, but it may also introduce excessive sharpness or texture. Compare the single-pass and two-pass results before deciding which to keep.

By Input Format

RAW Images

RAW files retain more of the original image data captured by the camera than JPEGs typically do, giving you greater flexibility when adjusting exposure, white balance, and tonal details. However, RAW images can still contain high-ISO noise, softness, or limited fine detail, depending on the shooting conditions.

Aiarty Image Enhancer supports a range of RAW formats, including DNG, CR3, CR2, NEF, ARW, and RAF, so you can enhance supported RAW files without first converting them to JPEG.

Which AI Model Should You Use?

Choose a model based on the image content and your enhancement goals, rather than the RAW format itself. Real-Photo v3 is a useful starting point for natural-looking enhancement of real-world photos. If you want more pronounced details, compare it with More-Detail GAN v3.

Workflow Tip

For greater control over the final image, adjust exposure, white balance, and other basic settings in your preferred RAW editor first. Then use Aiarty Image Enhancer to refine clarity, reduce distracting noise, or enhance fine details. You can continue editing or export the enhanced image in a supported format afterward.

By Output & Workflow

Aiarty Image Enhancer supports different output needs and photo editing workflows, whether you want to improve image quality without enlarging it, continue editing in Lightroom, process multiple photos efficiently, or prepare images for high-resolution printing.

Enhance Without Upscaling

If your image already has enough pixels for its intended use, you may not need to enlarge it. Choose x1 to improve image quality while keeping the original pixel dimensions.

This is useful when you want to reduce noise, correct softness, or clean up compression artifacts without increasing the image size.

Lightroom Workflow

Aiarty Image Enhancer can work alongside Lightroom Classic, allowing you to use Lightroom for your regular photo adjustments and Aiarty for AI-powered enhancement.

In Lightroom Classic, select a photo and choose Edit In > Edit in Aiarty Image Enhancer to send it to Aiarty. Apply the enhancement settings you need and export the processed image. You can then continue working with the enhanced photo in Lightroom Classic.

Add Aiarty to Lightroom

This workflow is useful when you want to keep your existing Lightroom editing process while adding another step for noise reduction, sharpening, or upscaling.

For detailed instructions, see our guide to using Aiarty Image Enhancer with Lightroom Classic.

Batch Apply Settings to Multiple Images

When you have several photos that need similar treatment, batch processing can save time. You can apply the same settings across multiple images or configure each photo individually when their needs differ.

To apply the same settings to multiple images:

  1. Click one of the images and configure its settings, including the AI model, upscale factor, and Strength.

  2. Click Batch Export to apply the current settings to the other images in the batch.

If the images require different settings, select each image individually, adjust its settings, and click Single Export for that image.

Batch processing works best when the photos have similar quality issues and enhancement requirements. For mixed batches containing portraits, wildlife, and heavily compressed images, individual adjustments may produce more suitable results.

FAQs

  • 1. Which AI model should I use for portraits?

    For realistic portraits, start with Real-Photo v3 for natural-looking enhancement. If you want more pronounced detail in areas such as hair, eyes, and skin texture, compare the result with More-Detail GAN v3. For soft or low-resolution faces, try enabling Face Restoration and compare the results before exporting.

    The best choice depends on the original image quality and the look you want to achieve.

  • 2. Which AI model should I use for old photos?

    Start with Real-Photo v3, which is designed for real-world photos and old-photo restoration. Adjust Strength to balance clarity and natural texture. If faces remain blurry or lack definition, try Face Restoration and compare the available restoration modes.

    For heavily damaged or extremely low-resolution photos, review the result carefully to make sure reconstructed details still look natural.

  • 3. Which model is best for reducing noise while preserving details?

    For realistic photos, start with Real-Photo v3 for a natural-looking result. If you want stronger detail enhancement, compare it with More-Detail GAN v3.

    Adjust the Strength slider to balance noise reduction, sharpness, and texture. If the result looks too smooth or overly sharpened, lower Strength and preview the image again.

  • 4. How do I avoid waxy or plastic-looking skin?

    Start with a model suited to realistic photos, then adjust the Strength slider to reduce the intensity of enhancement. Avoid applying Face Restoration automatically to every portrait; enable it when facial details need additional reconstruction.

    Zoom in to inspect skin texture and facial features, and compare the enhanced result with the original before exporting.

  • 5. Should I enable Face Restoration for every portrait?

    No. Start by enhancing the image with a suitable AI model and adjusting Strength. If the face already looks clear and natural, additional restoration may not be necessary.

    For old, blurry, or low-resolution portraits, try Face Restoration and compare the result. Choose Alpha Overlay when you want to better preserve the original colors and appearance, or Gradient Overlay when a face needs stronger reconstruction.

  • 6. Should I enhance images before or after editing them in Lightroom, Capture One, or Photoshop?

    A practical workflow is to perform your basic edits first, use Aiarty Image Enhancer for AI-powered enhancement, and then return to your photo editor for final adjustments.

    • Before enhancement: Adjust exposure, white balance, and basic tonal settings as needed.

    • In Aiarty: Reduce noise, improve clarity, restore details, or upscale the image.

    • After enhancement: Fine-tune color, contrast, retouching, and other finishing adjustments.

    The ideal order depends on the image and your editing workflow. For example, you may prefer to reduce noise before applying strong sharpening or to make final color adjustments after enhancement.

  • 7. In what order should I use Image Enhancement, Face Restoration, and AI Eraser?

    A useful starting workflow is:

    1. AI Eraser: Remove unwanted objects if necessary, then inspect the reconstructed areas.

    2. Image Enhancement: Improve overall clarity, reduce noise, and upscale if needed.

    3. Face Restoration: Enable it when faces need additional detail or reconstruction.

    4. Final review: Check edges, skin texture, colors, and any reconstructed areas before exporting.

    Not every image needs all three features. Preview the results at each stage and avoid applying extra enhancement when the image already looks natural.

  • 8. What should I do if the enhanced image has unwanted color shift?

    Open the Color section and find Restore Color. Increase its value to bring the enhanced image's colors closer to the original. You can also fine-tune Color Temperature and Tint if needed.

    Preview the result and adjust the settings until the colors look natural.

  • 9. What should I do if square or checkerboard-like artifacts appear after enhancement?

    Try changing Max Tile Size in the settings. Preview the result after each adjustment, as the best setting can vary depending on the image and processing conditions.

  • 10. Do different AI models have different GPU requirements? Can my GPU run Aiarty Image Enhancer?

    Aiarty Image Enhancer can use CPU or GPU processing, and GPU acceleration can improve processing speed. The actual performance depends on your hardware, image dimensions, and processing settings.

    The published system requirements describe supported hardware for Windows and Mac, but do not specify a separate VRAM requirement for every AI model. To check your hardware, open Aiarty Image Enhancer and select Hardware Check from the top-left menu. You can also consult the official system requirements.

  • 11. Does Aiarty Image Enhancer require an internet connection?

    An internet connection is required to register the software and download AI models the first time they are used. Once a model has been downloaded, image processing does't require a continuous connection.
