Although I find some of the cabin shots posted here on A.net to be interesting, in general I'm much more interested in seeing the outside of an aircraft, and I have yet to attempt to upload a cabin shot here. However, I'm flying on Air Canada's new 777-300ER next Monday, and I thought that would make an interesting cabin shot. As an experiment I made my first-ever attempt at a cabin shot yesterday on a Pinnacle CRJ - the flight attendant was far more interested in her knitting than anything else going on in the cabin, so I got bold.
I did not use the flash on my 300D for obvious reasons, and the results were unfortunately horrible. I stood at the rear of the cabin and shot down the aisle. Most of the window shades were open, causing the areas around the window to be overexposed, while the center of the cabin was underexposed. I set my ISO to 200, but even with that and f5.6 my shutter speed was only 1/25, a bit too slow for handheld for my hands on a moving aircraft. Prior to my 777 trip, any pointers anyone can give me for a simple cabin shot will be welcome (or a link to a previous post covering this in detail as I couldn't find anything helpful).
