I just made the conversion on my camera with the straight 3 pack of AAA's but then I'd have to keep it on the outside. I found a tutorial on how to use the 4 pack and remove one compartment but it seems complicated and you have to mess around with the camera a little more - however, it would fit in the compartment. My question is, would I be able to just use 4 AAA's to power the camera or would that make the images underexposed? My idea there is that too much voltage will make the meter read higher than it should and therefore underexpose the image. Anyway, any information would be great - thanks!
