Common Mistakes to Avoid
1. Using Low-Resolution Source Images
Reason: Attempting to upscale an already blurry or pixelated image will result in a blurry, artificial-looking result, no matter how good the upscaling algorithm is.
Solution: Start with the highest resolution source image possible to maximize the quality of the upscaled result.
2. Over-Upscaling
Reason: Increasing the image size excessively leads to significant detail loss and unnatural artifacts. The algorithm has to guess too much, resulting in a poor outcome.
Solution: Upscale in smaller increments and preview results to find the optimal balance between size and quality.
3. Ignoring Noise Reduction
Reason: Upscaling often amplifies noise and artifacts present in the original image, making the final result look grainy or messy.
Solution: Use noise reduction techniques before or after upscaling to improve the overall clarity and smoothness of the image.
FAQs
What is the best AI upscaling tool for Photoshop?
There's no single 'best' tool, as the ideal choice depends on your image and desired results. Popular options integrated with or compatible with Photoshop include Topaz Gigapixel AI, Let's Enhance, and Adobe's own Super Resolution feature (available in some versions). Experimenting with free trials or demos is recommended to find what works best for your workflow and image types.
Will upscaling always improve my image quality?
No. Upscaling increases the resolution, but it doesn't add detail that wasn't originally there. While AI upscaling can intelligently fill in gaps, the results are best when starting with a high-quality image. Severely low-resolution images will still appear blurry or pixelated even after upscaling, though significantly less so than the original.
