Originally posted by photoptimist you could use joergens.mi's suggestion of setting the camera in each mode, writing down the camera's "shots remaining"
A pie chart would show each picture and video format on the card, and it would show how much space is remaining according to each image format. I don't consider camera programming space limited, as its much easier for manufacturers to buy higher capacity memory than lower capacity. Actually even for consumers, lower capacity memory is going away in favor of higher capacity. 1, 2, and 4Gb memory cards have all disappeared from the store shelves in favor of 32Gb, 64Gb, and 128Gb.
Ok, thanks for the opinions, guess I'll bin this idea.
