I am using a Nikon D5200. I intend to do some image processing on the raw images shot with the camera. But I am encountering a problem when I read the raw images using GNU Octave. Rather than giving bit depth of 16 (since the .NEF are shot at 14-bit depth), the result is just a 8-bit array. What might be the problem?
imfinfo("/media/karthikeyan/3434-3531/DCIM/100D5200/DSC_1094.NEF")
ans =
scalar structure containing the fields:
Filename = /media/karthikeyan/3434-3531/DCIM/100D5200/DSC_1094.NEF
FileModDate = 10-Oct-2016 18:10:02
FileSize = 26735420
Format = DCRAW
FormatVersion =
Width = 6036
Height = 4020
BitDepth = 8
ColorType = truecolor
The result from exiftool is as follows:
exiftool DSC_1094.NEF | grep -i bit
Bits Per Sample : 14
I am using Ubuntu 14.04, Octave 4.0.3.
