Today I’ll go for another photography technique post.
I have been experimenting recently with the modified firmware for Canon 5D Mark III that allows to load the Magic Lantern advanced capabilities.
This group of hackers decided to exploit the camera possibilities to their maximum and managed to create a full framework of extended capabilities, much beyond what Canon had originally designed the camera for, and one of these capabilities is to shoot RAW files with dual ISO : in the sample above, even lines are exposed at ISO 100, and odd lines are exposed at ISO 1600.
This allows to considerably expand the dynamic range of the camera, and push shadows without getting much noise while preserving highlights from being burnt.
And in the picture above you can get a clear sky together with a nice foreground that would otherwise be very dark.
