speeding up filters in Photoshop

by Heather Young

Not in the mood to spend half an eternity waiting for Photoshop to process a filter on a large image? Here's a way to make things a little quicker. It's especially quick if you know your keyboard shortcuts.

  • Use the marquee tool to select part of the image. Select an area that's just big enough to give you an idea of the effect the filter will have.
  • Choose the settings for your filter, press ok or enter to apply.
  • Undo the filter. (Either go to Edit > Undo, or simply press Cmd + z if you're on a Mac, or Ctrl + z if you're on a PC.)
  • Deselect the area you selected with the marquee. (Either go to Select > Deselect, or simply press Cmd + d if you're on a Mac, or Ctrl + d if you're on a PC.)
  • Run the filter again. (Choose the first option from the Filter menu, or simply press Cmd + f if you're on a Mac, or Ctrl + f if you're on a PC.)
  • That's it!
