LE simulation via Bracketing, using shutterless, Full Res Silent Picture | |
Creates brackets for post processing a simulated LE exposure | |
User must set FRSP mode, ie DNG or MLV and also wheather to use Dual-ISO | |
BUT note that only DNG mode has been tested ;-) | |
Exposure Sim should be on | |
Should be in LV | |
It is best to have Canon review set to OFF | |
Base exposure should be between 0.25-14 secs | |
Version 0.8: Requires the Lua Fix | |
