My Olympus MFT Camera has a number of aspect ratio options. I think L/H its 1:1 3:2 4:3 16:9 and then its also got 3:4 Vertical I suppose 4:3 has the most pixels and is the RAW format. Which do you use and why? Even if I'm not doing RAW processing and just using the JPG should I use 4:3 so I have something to crop? Does anyone pick image aspect at the time of shooting on a per picture basis? IF you are printing snapshots exclusively (does anybody do that anymore? - I suppose not if you have anything more than a point and shoot) do you pick 3:2 to match the 6"x4" format of snapshots?
