Re: Yet another "prints-darker-than-screen" but with a twist...!

Back with an update. I tried measuring my monitor luminance with my camera, an Olympus OMD-EM5 (which I absolutely adore btw - completely irrelevant! :P). I used the method described in the former posts, but since it wasn't complete and couldn't have any measurement that would be of value, I searched around and found out a nice method here  and with quite some help from the tables here .

While having my monitor brightness to 0 and contrast to 70, I measured a completely white background with my camera, at ISO 200 and f/5.6 . Shutter speed was about 1/25, so basically this means that I have an EV slightly larger than 9, between 9 and 10 (by consulting the appropriate table), or in fact, an EV between 10 and 11, since my ISO is 200, not 100 like in the table.

Therefore, a value of 10+ EV gives me roughly a value of ~128 cd/m2 (or a little more), which is quite good, even though not perfect for printing.

That is a very nice method to approximate your monitor's brightness if you don't have a dedicated tool, and it seems quite accurate for the roughness of it.

The procedure solidified my belief that I'm pretty close (at least as close as one can get without a calibrator). If only I could find a way to further reduce brightness by a hint, closer to ~100 cd/m2, I think that would be perfect. :-/

Any thoughts?
