4th time typing this... missing a ton of filters... artistic, brush, pixillate...help.
also i apparently have the extended edition. i find that i can only get to them in filter gallery
What version of photoshop and operating system?
Have you moved or copied any plugins from older versions of photoshop into your present version?
That threw me off when you said pixelate, but anyway in cs6 you can go to Preferences>Plugins and check Show All Filter Gallery Groups and Names
