Title: ISO experiments (iso-research)
Post by: Audionut on January 28, 2021, 01:38:13 AM
Experimental builds based on CMOS/ADTG/Digic register investigation on ISO (https://www.magiclantern.fm/forum/index.php?topic=10111).

Just a small improvement in dynamic range in photo mode (around 0.3...0.5 0.8 stops). We were able to fine-tune the amplifier gains in order to squeeze a little more highlight detail.

Feel free to discuss build related issues in this thread, and if you would like to contribute with some more technical related things, the original thread is probably best suited.
