Some 'camera tone mapping' results

Post by **OnoSendai** » Mon Oct 08, 2007 1:39 pm

Here are some results, after calibration, using data from Carbon's experiment. See http://www.indigorenderer.com/joomla/fo ... php?t=2046 for more details

Camera was a Nikon D80

Camera white balance was set to 2800K.

Indigo white point was set to A (correlated colour temperature of 2856K)

More results will follow shortly.

8 second exposure:

nice - colour looks better than the actual photo

great to finally have Indigo calibrated!

What I can see, is, that your renders are more saturated than the shots...

Could be an Exponent + bumpmap issue (or the lack of one), though....
would be very hard, to get that right.
Oh, and it also could be the lack of that black cloth, that also reflects light, which gets ignored in your test...

especially the very dark photo shows bandings, so, Indigo is superior in that point.

Besides those two things and the slightly folded appearance of the photo-chart and some slight noise in Indigo, they match

GREAT WORK!!!!

I think the color issue is due to the camera software, the sensor, ...
Looks pretty good I think, quite close, close enough for me

All I can say, it's WOW. Great job ONO. I think this is as close as it's going to get considering all the conversion factors and different environment (studio/indigo).

Just WOWOWOWOW..

Thanks ONO..

hi Ono
did you used the jpeg or raw files, because jpgs are indeed processed by camera software, raws are usually less saturated in their default.. and also have less contrast..

and Kram, what you see is not black cloth but glance of black velvet (nothing is less reflective except black fur)..

banding is caused by uneven glass of clear light bulb..

Very very nice stuff Ono!
I can't wait to use it.

Ok I guess this is what the new exposure settings is for

Now if I just knew what all this meant and how to use it!

A page that explains the difference between the three tone mapping methods would be nice. Can someone post a link please.

Indeed the documentation is lacking. Would be cool if someone could update the wiki, before leaving 3d and Indigo ^^

thx
