The following assumptions were made to calculate the number of images per card(SanDisk):
MP = 1,000,000 pixels
1MB = 1,000,000 bytes, 1GB = 1,000MB
TIFF image has 24 bit color depth, one of 16,777,216 colors per pixel
JPEG 100% Quality = Visually lossless JPEG compression with 1:10 ratio of RAW image
