Re: Prepare Images for dcraw

AFAIK you cant. The raw data is not comparable to that of a normal can because the way the sensor works. The sensors reads and records pixel by pixel instead of a one time exposure. So you can only recreate the process in which the sensor recorded the data. I wish they would use another name then R...

Re: Interesting Python "awb_gains" Compatibility Issue

This is not a solution as you cannot manipulatie WB in greyworld. It is therefor pretty useless for f.i. academic purposes.

Re: New AWB algorithm in test firmware

Re: New AWB algorithm in test firmware

Re: AWB Off does not work and fixed whitebalance gains cannot be set

Seems to have to do with the new awb setting -awb greyworld . Just updated the firmware with rpi-update.and it works fine again and the greyworld option as added value.

I take that back, works not for the color, only the color of the thumbnails.

Re: Ubuntu Mate or Server doesn't boot on Raspberry Pi 4

:idea: Just install mate-desktop from Raspian repo. Want a server? Choose the console config in raspi-config boot setting. Rermove all desktop bloatware. :idea:
