Hello again,
I've been using this, with good results.
I updated my git version and realize that there was no presents any more
for the E-PL1.
Some changes have been made. Now there's noiseprofiles.h.
The presets are only present now, if the picture was taken with that
camera, right?
When I first did the profiling, I entered the name of the camera and
iso's by hand,
so I changed this:

now the presets are there again.
Can this be applied to master?
You told me that was something wrong with the blue channel.
When I have the time, I will take a new set of shots and do another
profile, this time with all ISO stops.
Please continue the great work,
Best regards,
José Carlos
