I updated the AVS Project Contrast thread sticky at the top of this forum ( http://www.avsforum.com/avs-vb/showthread.php?t=852467 ). It now includes a ton of details on the Sony DI, including measurements of dynamic contrast, dynamic gamma, contrast performance of Iris 1 vs Iris 2, etc. For people who are interested in the Sony DI implementation this is a must read.


Please feel free to add your comments, questions and criticisms at the end of the contrast thread. Here is a few tid bits that appear in the contrast thread:


The chart below shows the shadow detail/dynamic contrast results between iris off and iris 1 modes of the VW50.



Dynamic Gamma - Iris 1 vs Iris off



Dynamic Gamma - Iris 1 vs Iris 2



Dynamic Contrast Examination - Iris 1 vs Iris Off vs VW50 with same on/off performed natively.

How about the downside of DI ? My Pearl has noticeable iris pumping that drives me crazy in some scenes where it oscillates for up to 30 seconds. What causes this and can it be fixed ?
