Hans van Driest has posted a possible explanation of why Sony uses the tone compression algorithm that it does. It’s speculation, to be sure, but, if true, might explain a lot. Here is is post, lightly edited for clarity. Sony uses column conversion, meaning they use a lot of ADCs in parallel. This, in combination… [Read More]

Removing the delta modulation component from Sony raw compression
Someone expressed interest is seeing how the Sony tone compression/expansion simulation would work with our test image if the delta modulation component were removed, leaving us with only the 13-to-11-bit tone compression and its 11-to-13-bit counterpart. I’m glad to oblige. Here’s the target image in Adobe RGB: Here’s what it looks like in Adobe RGB… [Read More]
