I assume "90" refers to the angle of the bounce? When bouncing, the angle should always be such that you hit the subject. If you're 5 feet away from your subject and have a 10 foot ceiling, the bounce will be more than 90. If he's 30 feet away, it will be greater. The further away, the less need for the card. (That's what the plastic thing is, right? Not a diffuser?) If the angle of the bounce is more than about 75 degrees, much of the bounce is just hitting the floor. A *very* rough rule of thumb might be to subtract 1 to 1.5 stops for the ceiling bouce, add a .5 stop for the card. Basically, cut your effective range in 1/2, at least. Different ceilings have different reflectances. The often have odd colors too. Watch out for beams and chandeliers too. If you're not sure how much your bounce and reflector are weakening your flash power it's best to "flash bracket" - shoot some of your shots with your bounce/card outfit, shoot a few straight on with the flash without any modification/bounce. If in doubt, shoot the "money" shots with straight-on flash. tv
