I have a Canon S5 IS and my files always come out as .jpeg. So I am not sure why yours would have a .rgb file extension. I will have to check into this further. I don't have an extensive understanding of all the ins and outs of cameras and their workings though
As an aside, my Canon S5 IS has been giving me "lens errors" and shutting down. I have had it for over 8 years now and will miss it when it's gone
p.s. Thanks
@dave, for the new
emoticon. I really am despondent over my camera going bad
