Read in a photo magazine ling ago that Japanese studio wedding formal portraits (bride in ultra expensive kimono) are by default done using 8x10 large format cameras. Technical quality is beyond question. The wedding shoot cost a bomb.
In fact with the explosion of easy to use DSLRs and compacts in primary school childrens' hands, how do pros differentiate themselves?
By being the ultimate in technical quality and good composition. Use medium format digislrs with =>50MP backs or 8x10 inch format film cameras.
