Sorry, it still seem backwards to me: the picture comes after the format, not the format after the picture. I don't choose 'one format's aspect ratio over another format for a given image' because there is no given image: there's only what I compose in the space available.Regardless of how you feel about cropping, the question was relating to types of composition that you feel work well for a given aspect ratio. Why do you choose one format's aspect ratio over another format for a given image?
My logic tends to be:
1: Bigger format = better technical quality but slower in use
2: Camera (not format) most suitable for job, e.g. speed of operation, movements, lenses available...
3: Intended use of pic, e.g. magazine, exhibition, on line...
4: General preference of format: 5x7 inch a nicer shape than 4x5 inch
Of course there are times when I want to shoot panoramas but when I do there are lots of options. the widest non-pinhole format I have is 6x12cm but I can also electronically stitch smaller formats (I've done it mechanically, too, with 35mm); use a split film format (e.g. 2x 2x5 inch on 4x5 inch film) or just crop e.g. 6x9.
Cheers,
