Hello everyone,
Since yesterday, I test DualISO mode on my DSLR.
In the menu, it is now possible to choose values as: 100, 200, 400, 800, 1600, ...
However, multiples of 160 ISO get better result to retrieve the dark tones, why not add: 160, 320, 640, 1250 ...?
To get there, I tested the functionality upside down, and I set the camera to ISO 2500, then DualISO on -5EV
Recovery of Shadows was better (less chromatic noise) than with the device in 100iso and DualISO 1600.
With 1250iso and DualISO -4EV and the results were also better.
What do you think?
Thanks
