There's always time for flashing :). Thanks for the info, I like to have control :)

Can someone give me more easier instructions to get the uncompressed file?
Of course i read and know the disclaimer.

Thanks

Ooh, that's really neat. You could change the image format to something other than jpeg if you wanted to using that file (to anything GStreamer supports, it looks like). Nice.

Has anyone tried making changes to the config file, and if so, did you at any time go beyond specified parameters and cause issues? Would love to know success/failure in this regard.

Thanks, Thor

I changed it to 99% and the pics seem (quite a lot) better to me. I'd do some before and afters, but I'm having problems SSH-ing into the phone.

OK, I've taken pics at 80% and 99% compression.

80%
99%

The 99% one is nearly five times the file size, but I can't see much difference between them, except maybe on the kindling on the right.

I like my pillows, i'll leave the compression low.

Joshv06, good one!

Yeah. I played and tweaked the settings quite a bit, and tested various things - the default setting is pretty good compromise - so I ended up leaving it at where it is. The more important thing for good quality pictures is to use enough light. So instead of pondering jpeg compression (which is really not making a significant difference here) - add more light. Move closer to the window, add a desk lamp (and set white balance accordingly to tungsten if it is such) or be creative some other way. This is what makes the shot initially less noisy, thus requiring less noise reduction. This makes the most difference really.

I'll be writing a quick wiki tutorial about my experiences with the N900 camera.

Indeed if you pay close attention, at 80% compression you can see more artifacts than 99% compression....but the difference is not big.
