Hi, Just wonder what the thoughts are on Dual ISO from MagicLantern as it does take two images at differant ISO's and puts them together in software. All I did here was set W&B points with the ALT key held down and a crop. Thanks, Russ

It can definitely increase the native dynamic range of a standard raw file - often at the expense of the resolution of the standard raw file. Sometimes it can lead to artifacts related to moiré and color fringing. And, of course, there is the necessary processing that converts the dual-ISO DNG to a working DNG. Depending upon your application and workflow, the use of the dual-ISO module could definitely be worth it.

A thread I started (in 2013) when dual-ISO became available on my cameras:

I know that BigAl uses DualISO workflow on his airshow images too. There are several other forum members that use it as well. It definitely extends the available dynamic range and the verbose output from the conversion utility (cr2hdr) gives effective dynamic ranges of about 14EV, which is pretty good.

EDIT - I see you got into that thread.

I use a 5DIV now, so I have not used dualISO for while. I would call the dualISO hack a "medium dynamic range" image.
