要修正Photoshop中的色差問題，首先使用鏡頭校正工具自動(dòng)校正，其次可手動(dòng)調(diào)整色差滑塊，針對RAW文件建議使用Camera Raw進(jìn)行更精細(xì)的控制，必要時(shí)採用高反差保留和克隆圖章工具手動(dòng)處理頑固色差，最後可通過保存配置文件提高後續(xù)工作效率。具體步驟為：1. 使用濾鏡→鏡頭校正→色差選項(xiàng)卡調(diào)整去邊f(xié)ringe 滑塊；2. 對RAW 文件使用Camera Raw 的“去除色差”功能並微調(diào)紫綠色調(diào)範(fàn)圍；3. 對殘留色差複製圖層後應(yīng)用高反差保留並混合為“亮度”模式，再用克隆圖章小心處理；4. 若常用特定鏡頭組合，可在Camera Raw 中保存設(shè)置為新預(yù)設(shè)以便快速應(yīng)用。

Chromatic aberration — you know, that pesky color fringing around high-contrast edges in your photos — can be a real annoyance. The good news? Fixing it in Photoshop is actually pretty straightforward if you know where to look.

Use the Lens Correction Tool

Photoshop has a built-in way to tackle chromatic aberration through its Lens Correction feature. This tool works best when you let it auto-correct based on the lens profile, but you can also tweak things manually.

• Go to Filter > Lens Correction
• Switch to the Chromatic Aberration tab
• You'll see sliders for Remove Fringe from Edges — adjust these to reduce green/magenta or blue/yellow halos
• If the automatic detection doesn't catch everything, zoom in on problem areas and fine-tune

One tip: this works best on JPEGs or smart objects. If you're working with raw files, consider using Camera Raw first (more on that later).

Try Camera Raw for More Control

If you're editing raw images, Adob??e Camera Raw gives you even better control over chromatic aberration. It's basically the same toolset but with more precision.

• Open your image in Camera Raw (right-click the layer and choose “Convert to Smart Object” if needed)
• Go to the Lens Corrections panel
• Under the Color tab, check the box for Remove Chromatic Aberration
• Fine-tune the sliders for Purple Hue Range and Green Hue Range if needed

This method often does a better job because raw files retain more data, especially in those tricky edge details.

Manual Fixes for Stubborn Cases

Sometimes the automatic tools miss spots — especially in high-megapixel images or extreme crops. In those cases, you might need to take matters into your own hands.

• Duplicate the layer
• Use the High Pass filter on the duplicate layer and blend it with the original using the Luminosity blend mode
• Zoom in and use the Clone Stamp Tool carefully on small fringes that won't go away
• Avoid over-sharpening — that can actually make chromatic aberration worse

Just keep in mind: manual fixes take time, so only do this if the fringing is really distracting and the automated methods don't quite cut it.

Work Faster with Profiles

If you shoot with the same camera and lens combo often, Photoshop lets you save lens correction profiles. Once you've dialed in the right settings, click Save Settings as New Preset under Camera Raw. That way, next time you shoot with the same gear, you can apply the fix with one click.

So yeah, correcting chromatic aberration in Photoshop isn't bad once you know where to go. Start with Lens Correction or Camera Raw, and only dive into manual fixes if you have to.
