I shoot about 99% of the time in 3:2 format. This holds true to whatever camera I am using, may it be a rangefinder, a DSLR or even on a Micro 4/3s which is optimized to the 4:3 ratio. I am very comfortable with the 3:2 ratio. Having said that, sometimes I do like to shoot in a different format like the 16:9. It enables me to see the world differently, and the compositional techniques will differ to a certain degree. The 16:9 is a widescreen tv ratio. It is refreshing at times to mix up the ratios here and there, but do not overdo them. I’ll leave you with some shots using the 16:9 ratio. It’s fun!
