Code: Select all
raspistill -w 1296 -h 972 --raw -o test.jpg
Also, I was able to decode the raw file to Adobe DNG using the raspiraw tool and it is in fact 2592 x 1944 pixels.
I was hoping to use the raw output to compare the effect of 2x2 binning on low-light noise performance, but I'm not sure how to get 2x2 bin mode from Raspistill. Does the --raw option force the sensor to full-resolution regardless of requested JPEG size, which is then done by a GPU downsample ?
