find that magic command. By a combination of educated guessing and trial and error. This needs for someone to have both cameras, or for two or more people who have the different cameras to cooperate together and hunt for the right command which unlocks the mystery. I am out of this one because I don't have one of the cameras currently in question. But I did have a big pile of mr97310a cameras, and that is exactly what I did. Started sending various commands and checking whether or not I got different results until I found what works. So, good luck. The answer is probably there if one looks for it.

long silence from here, but there has been illness in the family. I do keep trying to watch whatever is going on. Hans, I agree with your general characterization of the public's perception of 0 versus 1. But on this particular occasion I suspect that the general public would see that 0 corresponds more naturally to "off" than 1 does. Hoping that all is well with you and others. Cheers, and this is just my two cents on a trivial issue.

d decompression for the JL2005B/C/D based still cameras. The compression algorithm is pretty much standard JPEG, but two things are unusual. First, the compression or decompression proceeds down columns of width one block, not across rows. Second, the thing which is being compressed is the Bayer pattern, so each block is of width 16, not 8, and there are sub-blocks for each of R, G1, G2, and B. If anyone is curious about this, the code can be pulled down from gphoto.svn.sourceforge.net, in trunk/libgphoto2/camlibs/jl2005c.
