File size is one good reason. My 5DII spits out raw files at around 24MB each and when converted to 16Bit TIFFs they weigh in at around 126MB, uncompressed. With compression they can still hit around 70MB which isn't as memory card friendly as the initial 24MB. Your question mentions .PNG files - the uncompressed 16Bit .PNG equivalent is still 115MB so ...


Wouldn't it be useful to have a 24-bit RGB format (taking advantae of the camera's automatic processing modes)? Not really. Raw files are actually very space efficient, since they only store one greyscale channel, in 12 or 14 bit per pixel. A lossless 24bit format will inevitably create larger files, while dropping 4 or 6 bits of dynamic range. A 48bit ...


The JPEG format is very good for final output, filesizes are small and with the highest quality settings artifacts are pretty much invisible. It's only if you start editing a JPEG that you will see artifacts and the limited dynamic range. So it's a bad format if you plan to later edit images. If you plan to later edit images than RAW is far better than ...


Some do — for example, most or all Pentax models and higher-end Nikons support TIFF (which, as Raheel Khan notes in a comment above, is better for metadata than PNG). So, there you go. If this is important to you, you can choose a camera which has it. However, it seems that it's not important enough to most consumers to make it something people decide on — I ...
