During his talk he was able to give a practical demonstration on the differences in the way Adobe Lightroom processes images between its 2010 and 2012 setting with some apparent clipping taking place in the latter. I am sure this has given some people food for thought and has certainly got me planning to run some tests on images of my own.
Coincidentally I had been chatting with a friend that same day regarding colour perception. Dennis displayed an image on the same lines. The one I was talking about was:-
a) A
b) B
c) they are both the same,
The correct answer is c). Feel free to check this out. I have done so several ways and they are indeed the same colour.

ReplyDeleteThat is an excellent example of how Luminance Contrast can seriously play tricks on what you perceive as tonal values...Even when you show people how B is the same tone as A they don't believe it and ask to see it again, At least it is better than the Dress for testing visual perception!
