Using filters
To use a filter, choose the appropriate submenu command from the Filter menu. These guidelines can help you in choosing filters: - Filters are applied to the active, visible layer or a selection.
- Most filters can be applied cumulatively using the Filter Gallery. All filters can be applied individually.
- Filters cannot be applied to Bitmap-mode or indexed-color images.
- Some filters work only on RGB images.
- All filters can be applied to 8-bit images. Only the following filters can be applied to 16-bit images: Blur, Average Blur, Blur More, Gaussian Blur, Motion Blur, Noise, Add Noise, Despeckle, Dust & Scratches, Median, Sharpen, Sharpen Edges, Sharpen More, Unsharp Mask, Stylize, Emboss, Find Edges, and Solarize.
- Some filters are processed entirely in RAM. If all your available RAM is used to process a filter effect, you may get an error message (see Improving filter performance).
