[Sticky] DSLR - calibration masters, BPM, have different size ?
This question was asked by @peju, I have moved this to a separate topic:
My Master D/F are pre-made for each iso, expo and separated for each camera model Im using. and follow the instructions how to made them. Now I noticed they coming out with a different pixel size than the subs.
The APP told me that these M-F/D is not same size as the subs and will not be used in the process.
Is this problem familar ?
Best regards, Peter
This is not a problem, but normal.
For DSLRs, the sensors are bigger than the image dimensions of the regular frames. All frames have raw borders and these are removed in the raw conversion as a final step. All raw converters do this.
APP calibrates all DSLR data using the whole sensor. So all Masters and Bad Pixel Maps will have image dimensions of the whole sensor.
So the difference in image dimensions are the raw borders that are cut-off from frames. The raw borders usually don't contain any usefull data so we need to crop them away.
Let me know if this clarifies it 😉
@peju, If APP tells you that the calibration masters don't have the correct size for the light frames, than you are not loading the original CR2 frames for calibration, which you must do.
You are probably loading fits files that were processed already?
