Tina when your put your camera on a tripod to test your film or lens you're not testing your tripod. You're testing the sharpness of your film and or lens. Your just taking out the variable of the hand holding which is quite high. If you don't use a tripod it could be said all your testing is your hand holding ability. Exceptions would be be if you were using a flash whose very fast durations make for a realistic expectation of how much sharper one lens might be over another. Or film or sensor. Perhaps another would be the Bonneville Salt Flats at high noon. On a Tuesday.
