去除瑕疵或改善皮膚質(zhì)感而不破壞原圖質(zhì)量的關(guān)鍵是採用非破壞性編輯。首先使用帶有獨(dú)立圖層的修復(fù)畫筆工具，在上方新建一層並開啟“採樣所有圖層”選項(xiàng)，按住Alt鍵（Mac上為Option）採樣乾淨(jìng)區(qū)域後單擊瑕疵處，100%放大檢查邊緣自然度。其次嘗試頻率分離法控制皮膚質(zhì)感，複製兩層後對頂層應(yīng)用圖像設(shè)置減去模式、偏移128、比例2，設(shè)為線性加深混合模式並模糊底層直到紋理消失，再將頂層反轉(zhuǎn)並切換迴線性光模式，從而分別調(diào)整顏色和紋理。最後通過曲線調(diào)整層對中間調(diào)進(jìn)行明暗調(diào)整，創(chuàng)建曲線調(diào)整層針對陰影或高光微調(diào)S型曲線，用柔邊畫筆在蒙版上繪製僅顯示需要的效果，必要時(shí)降低圖層不透明度以保持自然過渡。這些方法雖比直接克隆稍複雜，但提供了更高的靈活性和更佳效果。

When it comes to removing blemishes or smoothing out unwanted skin texture without damaging the original image quality, the key is working non-destructively. That means using tools and techniques that preserve the original pixels while letting you make reversible changes. This approach is especially useful for retouching portraits where maintaining a natural look is essential.

Use the Healing Brush with a Separate Layer

Instead of painting directly on your image layer, create a new empty layer above it and use the Healing Brush with the "Sample All Layers" option turned on. This way, all your fixes are isolated on their own layer, making them easy to tweak or remove later.

• Hold Alt (Option on Mac) to sample a clean area near the blemish
• Click once on the spot — don't drag or overdo it
• Zoom in to 100% to make sure edges still look natural

This method keeps your original image intact and gives you full control over how much healing you're applying.

Try Frequency Separation for Skin Texture Control

Frequency separation splits an image into two layers: one for color and tone, and another for texture. This lets you smooth skin texture without affecting the underlying tones, which helps maintain realistic results.

• Duplicate your layer twice
• On the top layer, go to Apply Image (under the Image menu), set blending to Subtract, offset 128, scale 2
• Set this layer's blending mode to Linear Burn
• Blur the lower layer until texture disappears
• Flip the top layer and switch its mode back to Linear Light

Now you can work on each layer independently — softening texture on one, adjusting color on the other.

Dodge and Burn on Midtones Using Curves

If the issue isn't a blemish but uneven texture or lighting, dodging and burning selectively on midtone areas can help even things out. Create a new Curves adjustment layer and target the shadows or highlights to lighten or darken specific spots.

• Make subtle S-curve adjustments to increase contrast locally
• Paint on the mask with a soft brush to reveal the effect only where needed
• Lower the layer opacity if it looks too strong

This technique avoids harsh transitions and keeps the edits looking natural.

These methods take a bit more setup than just cloning everything away, but they give you much more flexibility and better results. Non-destructive editing isn't just about being safe — it's about having creative freedom.基本上就這些。
