This is probably better addressed in the development forum
Ok. I have my new port dumping (sd780) a really raw image. However even rawtherapee does not open it... How do I determine if the file that is being dumped is valid in any way? The raw is 12-bit. I've read that I may need to add a new setup to dcraw for my new camera? Should I drop RAW entirely and use DNG for determining if things are going ok?
I'm a little confused how I should debug a RAW output that has no format. LOL
Any advise or links are appreciated.
If you just want a quick look to see if the image is right, there are some programs you can load it into. For example, using irfanview you can use "open as->raw file" and then set the parameters you think are right for your cam. If you have the right buffer in CHDK and the right parameters, you'll see an image.
You can also write a very simple program that takes the 12bpp packed it into something more common (like 8 or 16 bit raw which you can then load as a greyscale in photoshop or gimp). I've attached the one I used in the
sd990 port.
For actual shooting, I'd probably just go with DNG, although you could certainly hack dcraw if you want.
