Using filters

    To use a filter, choose the appropriate submenu command from the Filter menu. These guidelines can help you in choosing filters:

    • The last filter chosen appears at the top of the menu.
    • Filters are applied to the active, visible layer.
    • Filters cannot be applied to Bitmap-mode or indexed-color images.
    • Some filters only work on RGB images.
    • Some filters are processed entirely in RAM.
    • Gaussian Blur, Add Noise, Dust & Scratches, Median, Unsharp Mask, Solarize, and High Pass filters can be used with 16-bit-per-channel images, as well as 8-bit-per-channel images.
