Photoshop filters are not available usually result from problems with layer type, color mode, or settings. 1. The text layer, adjustment layer and vector shape layer need to be converted into smart objects or rasterized before filtering can be applied. 2. Some filters only support RGB or 8-bit channel mode, and need to be checked and changed to the appropriate mode. 3. When using smart filters, the new filter will be added to the list instead of taking effect directly. If you need to apply it directly, you should first rasterize it. 4. The existence of a selection or mask may affect the use of the filter. You can cancel the selection or copy the maskless layer attempt.

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 requires 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.

Basically that's it.
