Thanks to all who have posted. This is all very helpful.
What I did with my SQ-A, since I can't seem to get my poorly designed manfrotto head to tilt more than 90 deg, is mount the tripod on the ceiling (or use a crane if shooting outdoors) and compose while laying on the floor on my back (a pillow is handy). Then, for printing, I took an angle grinder and a jack to my 6x6 neg carrier so I could rotate it 45 deg for printing. After getting the print mounted and hung (using a mirror, of course), I then have people view while laying on their side using the same aforementioned pillow and bingo! it looks great!
Sometimes I find myself turning a 6x6 folder 90 degrees for a better composition.
Do the tones change if you rotate it clockwise as opposed to anti-clockwise?
See! Now, this is getting really confusing!
I often hear people in Europe who quote paper and film sizes say the width first, then the height. In other words, where I might say a photograph is 8x10, a person from across the pond might say 10x8.
When I'm talking about the frame of my Rolleiflex, should I call it a 6x6 or should I call it a 6x6?
Inquiring minds want to know!
If you break it forward, can you see into the future?
