I think it would be better to use LM7809, which is a 9V part: 7810 is 10V. It is only just rated for 1A though, which is a bit close to the OPs 750mA estimate for his camera current drain. http://www.fairchildsemi.com/ds/LM/LM7809.pdfSilicon diodes drop .6 to 0.7 volts, so I think if you series 4 diodes (.6v * 4) = ~2.4v but if you parallel them for current-handling they may not share the current flow equally.
Anyway why not use LM7810 !
one component. with 3 leads: ground, in,out.
Yeah, If he can find one that can handle higher current, it would be better.
