Is there really a difference between 35mm and medium format for wedding photography?
Yes, medium format is clearly the choice of professionals, for several reasons. The vast majority of 35mm users have their film processed at a one hour lab. The process used by these labs is inherently unstable – they simply will not hold up over time. This is primarily due to the elevated temperatures used to quicken the process. Medium format has the added advantages of increased color saturation, the ability to be retouched more easily, capability of greater enlargement, use of professional films, and due to expense, the fact that users of this format are usually more experienced. On the other hand, 35mm equipment lends itself very well to strictly candid work where nothing will be enlarged over 8×10. It is faster, cheaper, and lighter weight.
