Creators of Photoshop (5)
I believe the answer is:
adobe
'creators of photoshop' is the definition.
(I know that Adobe Photoshop developer Adobe)
This is all the clue.
(Other definitions for adobe that I've seen before include "Clay dwelling" , "Clay used for sun-dried bricks" , "Sun-dried brick clay" , "house" , "Building material of clay and straw dried in the sun" .)
