Huh?

Use lossless compressed, at least.

You do have a solid and verifiable reason for making these statements? Yes?

About as solid as it gets: I've developed compression/decompression code for use in flight control computers. Lossless means precisely that: There is no difference between the original uncompressed data, and the data that comes back from the decompression process. If there was any difference - even a single bit - Boeing 777 airplanes wouldn't be flying.

But you said there was no reason (your emphasis) to use uncompressed RAW. The link that Jurwees posted says, under Uncompressed, "This method is useful for customers who wish to use 3rd party software to open their images."

There's one reason right there. Doesn't necessarily mean it's the BEST method to use, but it's there for a reason. Boeing 777 airplanes notwithstanding.
