550D + Magic Lantern Dual ISO finally works!
550D + Magic Lantern Dual ISO finally comes!
Here’s my initial test.
Dual ISO records RAW image with different exposure(ISO) for each alternate lines, so we need a processing after shooting(using cr2hdr tool given at Dual ISO page)
I’ve confirmed Dual ISO also works well for RAW video. The problem is processing Dual ISO image with cr2hdr requires a lot of processing time.
I am considering GPGPU optimization for faster Dual ISO movie processing. Stay tuned 😉
I am investigating “DSLR as an illuminance meter”.
Dual ISO will definitely improve the accuracy of “DSLR as an illuminance meter”, which will be valuable for physically-accurate IBL and HDRI footage used in CG/VFX.
