As a default, I set my digital camera view at the 3:2 aspect ratio, too, for similar considerations. The ratio of 4:5 also serves my practice with portrait and landscape subjects. Thank goodness we can easily switch ratios at will with digital photography.
In the mass portrait industry, it’s standard practice to install cropping composition masks in camera viewfinders. Ours had guidelines for 7:5, 5:4, 5:2, 3:1 aspect ratios, plus a head box for portraits and head & foot lines for full body portraits.
