what's up with this?

[memphishooter]

I put a 2 gig card in my D50, and the total number of shots is NOT double what it was with the 1 gig! One gig gave me 288 standard size files, but the 2 only allows 562. Doesn't make sense.

Every file saved will be of a different size - and there may be considerable variation. Depending on the image content, every file will compress to a different size. If your camera has an option to create a fixed file size (I don't recommend that), remember that the camera also creates a directory in the memory card which takes up some space.

1GB isn't 1GB and 2GB isn't 2GB...

When you format you will loose some of spaces this happens also to computer harddrives!

The image size also varies as mistermonday said... not much My RAW files goes 9MB to 12MB on 10,1MP.

I have 16GB card for my EOS 40D I get 15,6GB or something I think, lost of 400MB. How much you lost it depends on how much you have on your card, perhaps you loose 100-200MB or something on your 1-2GB!

When you double the size of the drive, the size of the File Allocation Table (FAT) increases. The FAT is like an index of where the files are located.

The bigger the drive, the more files you will have, the bigger the FAT will have to be.

It simply depends on file size you choose to save. It also depends on picture content every picture have different sizes.
