Hi, everybody!

I've used Rawdiger to calibrate lightmeter in my J1. An executive summary: there seems to be approximately 3.3 stops of headlight room in green channel.

The gory details can be found at http://stasvolik.net23.net/J1_Lightmeter.html .

Special thanks to Iliah Borg and Alex Tutubalin for this tools and for helping me to figure out how to do the job right.

Cheers,
Stas.
