用 AI 修圖：去背、修瑕疵、放大解析度一次學會
修圖不用再開 Photoshop 慢慢磨。用 AI，去背、消路人、補光、放大模糊照片，幾秒就好。這篇帶你看怎麼用、用哪個。
That One Photo That's Almost Perfect
You've probably experienced this: after finally taking a photo you like, you notice a passerby in the background, the lighting is a bit off, or it becomes blurry when enlarged. In the past, fixing these issues required proficiency in Photoshop, which took years to master. Now, with AI, these annoying little problems can be solved in seconds.
The Five Most Common AI Photo Editing Tasks
- Background Removal: cleanly remove people or objects from cluttered backgrounds.
- Object Removal: simply frame the object, and unwanted elements like passersby, power lines, or trash cans disappear.
- Upscaling: enlarge small, blurry photos and make them clear.
- Face Retouching and Beautification: naturally retouch skin and adjust expressions without looking fake.
- Lighting and Color Adjustment: brighten dark areas, unify color tones, and add depth to your photos.
Mainstream Tools to Choose From, Depending on Your Needs
- Background Removal and Product Photos: PhotoRoom, Pixelcut — can be done on your mobile phone.
- Object/Passerby Removal: Cleanup.pictures — frame the object, and it disappears.
- Upscaling and Old Photo Restoration: Magnific, Topaz, Remini.
- Portrait Retouching: Facetune.
- Professional-Level Color Grading and Editing: Luminar Neo.
A Practical Photo Editing Workflow
- Determine What Needs to Be Edited: background removal, object removal, or upscaling?
- Choose the Right Tool: don't try to do everything with one tool; each has its strengths.
- Edit Step by Step: remove objects, adjust lighting, and finally upscale and export.
- Check the Details: AI may occasionally produce strange results, such as distorted fingers or blurry edges, so review your work carefully.
Things to Keep in Mind
- Don't Over-Edit: especially with portraits, over-editing can make the subject unrecognizable.
- Keep the Original File for Important Photos: in case you make mistakes, you can always start over.
- Check Commercial Licensing: when using AI-edited materials for commercial purposes, be aware of the tool's commercial terms.
TheAI Academy Summary and Review
Honestly, the best part about AI photo editing is that it has made tasks that previously required Photoshop skills accessible to everyone. Removing passersby, upscaling blurry photos, and other daily editing tasks can now be done by anyone.
However, while tools can help, aesthetics are still up to you — AI can remove technical barriers, but it's your eye that determines what looks natural and good. Try using Cleanup to remove objects from a photo you've always thought was a pity, and you'll get hooked. For further reading: How to Use AI for E-commerce Product Photos.
In a nutshell: AI has removed the technical barriers to photo editing, but whether the result looks natural and good still depends on your eye.
