Hi Colin,

That's impressive you have had success using 2 cameras for the same scene, and as I imagined only doable by effectively eliminating any parallax effects. I think in the context of a TSE, this additional requirement would severely limit not only the artistic composition of the shot, but also the locations at which you shoot from. Generally, it is the foreground objects (nearby, or otherwise) that make a wide angle totality shot really stunning. For me, I like to remain mobile as well (i.e., move at the last minute if the weather is dodgy) so trying to find a good shot with no near foreground objects, at the last minute, may be too difficult and probably a deal breaker. Still, it's an interesting idea if anyone is willing to try it!

OK, so 1/10s is the limit for bulb via a PC. This is probably OK, as you can choose the correct ISO to not have to go faster than this. This way, you could probably shoot every 1 second, alternating exposures (then combine each set of 2 shots using layer blends). Effective cadence would be 2 seconds during totality, yielding a 2.5 second sequence at 24 fps (for a 2 minute duration totality).

The only problem I see with my suggestion of three separate sequences which are cross-faded together, is that there is little room to cross fade, particularly between sequences 2 and 3. I would imagine you'd need at least a second or two of footage overlap to do a good cross fade.

By the way, I have not seen any light curves, but will have a look.
