As it turned out, I returned to Venice in March 2012 ... just a few months later. On my agenda was to revisit Casa Goldoni with a "real camera." After dinner (3 slices of pizza), I headed back over to check out Casa Goldoni. Ah, the door was open and the lights were on. There was no way I could use a tripod due to the position of the iron bars on the doorway. Consequently, I placed my Holga on one of the cross-beams and held it snugly in place with my hand for several bracketed exposures. Got it!
Couldn't wait to see how much BETTER the film shot was in comparison to my iPhone photo. Boy, was I surprised ... same subject, same vantage point and basically the same lighting. Not the same aesthetics though. Check them out for yourself ... two totally different images.
Lesson learned ... sometimes the best camera for the job is the one you have with you!
