Raspberry cam 2.1

[ibmua]

Fails to make a correct file for me. I'm using raspberry cam 2.1. The tool writes
"Processing RAW data..."
and creates a 9.7mb dng file, but when I open it with Photoshop, the file looks like some strings of colors, not really a picture. Maybe, that has to do with this tool being done for Camera 1.3 and it's resolution, or something similar?

Edit: not sure your script actually works with the up-to-date true raw output by current raspistill version, though.

I encountered the same issue, but based on this:
http://picamera.readthedocs.io/en/release-1.11/recipes2.html#raw-bayer-data-captures
a simple change (attached the modified .c file which needs recompiled).
solves the issue.
raspi_dng.zip
This change doesn'-t autodetect the camera version, it assumes it's v2.

Btw - thanks for the original authors for raspi_dng, it's simple and it does the job!

My team came across the same issue and used this solution for a while.

In the end we created our own fork of picamera so that we could skip the DNG step altogether and load the data straight into a numpy array for our Python processing pipeline. If you'd like to do this check out https://github.com/OsmoSystems/picamraw/
