Filters

You can use filters in Clip Studio Paint to apply various effects to a selected raster layer. Filters are broadly categorized into "Blur", "Sharpen", "Effect", "Distort", and "Correction" categories.

You can use "Quick Filters" and "Quick Effects" to apply filters to a selected layer or over all displayed layers.

·You can create a selection area to limit the effect of the filter to only that area.

·Depending on the expression color of the selected raster layer, it may not be possible to apply certain filters.

·You cannot use filters if you are selecting multiple layers.

Quick Filters

Quick Filters adjust the colors of the image on the canvas. You can use Quick Filters from the Filter menu > Quick Filters dialog.

Apply to selected layer

Select the Filter menu > Quick Filters > Apply to selected layer to apply the filter only to the selected layer. Quick Filters can only be applied to raster layers with the expression color set to Color. In other cases, the following will happen.

·If you are selecting a layer type other than raster, a message will appear asking if you wish to rasterize the layer. After the layer is rasterized, you can apply Quick Filters.

·If the expression color is set to Gray or Monochrome, a message will appear asking you to confirm the change of expression color to Color. If you change the expression color, you can apply Quick Filters.

·If you are selecting a layer mask or selection layer, you cannot select a Quick Filter in the dialog. You can adjust some of the settings.

Apply to all

Select the Filter menu > Quick Filters > Apply to all (create merged layer) to apply the filter to all layers visible on the canvas. After you confirm the chosen filter and settings, a new merged copy of all layers will be added to the top of the Layer palette with the filter applied. The existing layers will remain unchanged.
