Deionized water is what all chem/bio/etc. labs use for "pure" water. It is
at least the equivalent of double distilled water. Many cartridge
combinations provide triple or better distilled water equivalent. 
So in most laboratory usages (photo lab included) deionized water would be
better than ordinary distilled water.

If my chem & photo lab experience has taught me incorrectly, I'm sure Mr.
Gower will correct me.
