Photoshop濾鏡不可用通常由圖層類型、顏色模式或設(shè)置問題導(dǎo)致。1. 文字層、調(diào)整層和矢量形狀層需轉(zhuǎn)換為智能對象或光柵化后才能應(yīng)用濾鏡。2. 某些濾鏡僅支持RGB或8位通道模式，需檢查并更改為合適模式。3. 使用智能濾鏡時(shí)新濾鏡會添加到列表而非直接生效，若需直接應(yīng)用應(yīng)先光柵化。4. 存在選區(qū)或蒙版可能影響濾鏡使用，可取消選區(qū)或復(fù)制無蒙版圖層嘗試。

You’re not alone if you’ve ever tried to use a filter in Photoshop and found it grayed out or unavailable. The issue usually comes down to your current document setup, layer type, or color mode — nothing’s broken, but something’s just not matching what the filter needs. Let’s break down why that happens and how to fix it.

1. The Layer Type Doesn’t Support Filters

Not all layers in Photoshop can accept filters directly. For example:

• Adjustment layers (like Levels or Curves) don’t support filters because they’re non-destructive edits.
• Text layers can’t have filters applied directly unless you rasterize them first.
• Shape layers or vector-based layers also need to be converted before using many filters.

? What to do:

• If you're working with text or a shape, right-click the layer and choose “Convert to Smart Object” or “Rasterize Layer.” Keep in mind that rasterizing makes the layer pixel-based and no longer fully editable as vector content.

2. Color Mode or Bit Depth Limitations

Some filters only work in specific color modes. For example:

• Filters like Oil Paint or Liquify require RGB or Grayscale mode. If you’re in CMYK or Lab color, those filters will be grayed out.
• Also, certain filters may not work in 16-bit per channel mode. Photoshop sometimes restricts filters for performance or compatibility reasons.

? How to check and fix:

• Go to Image > Mode and see which color mode you're in. Switching to RGB is often the easiest solution.
• To check bit depth: go to Image > Mode > 16 Bits/Channel — if there’s a checkmark, you’re in 16-bit mode. Try switching to 8 Bits/Channel if needed.

3. Smart Filters Are Enabled but You’re Trying to Apply Directly

If you’ve already applied some filters as smart filters (by converting the layer into a Smart Object), trying to apply another filter directly might not work the same way. Instead of applying directly, Photoshop adds the new filter to the Smart Filters list.

? What’s happening:

• You’re not doing anything wrong — the interface just changes. Instead of seeing an immediate effect, the filter shows up in the Layers panel under Smart Filters.
• This is actually a good thing because it keeps things non-destructive.

? Tip:
If you want to reorder or mask filters later, keep using Smart Objects. But if you really need to apply a filter directly, you’ll need to rasterize the layer first.

4. Selections or Masks Are Preventing Filter Use (or Vice Versa)

Sometimes, even if everything seems set up right, a selection or mask might affect how a filter appears or whether it can be used.

• Some filters won’t run if you have a selection active that doesn’t match the layer bounds.
• Other times, a corrupted mask or alpha channel can interfere.

? Quick fixes:

• Deselect everything with Ctrl D (Windows) or Cmd D (Mac) before applying the filter.
• If you suspect a mask is causing issues, duplicate the layer without the mask and try again.

Filter availability in Photoshop isn’t random — it’s based on how your document and layers are set up. Most of the time, a few quick adjustments will get you back to filtering like normal. Just pay attention to layer types, color mode, and whether you're working non-destructively or not.

基本上就這些。
