Auto ETTR does not change aperture, but this script will take your ISO and change the aperture accordingly (-1 EV for +1 EV) same with shutter speed, FRSP has a shutter speed limit, so, why not compensate with aperture?

Original Timelapse script:

--[[
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
Exposure Sim should be on
Should be in LV
Version 0.8: Requires the Lua Fix

maybe you wanna tweak some lines? Here's some info:

Hello, so, i have a little problem, a pin on my CF slot is gone, i was wondering, if i could copy files via USB (but i'm guessing it wont show any MLV) is i possible configure a lua script to bypass USB files and change all mlv to .mov? i would copy the files then change back to .mlv

Fixing the CF is not gonna be possible, no new parts where i live, i managed to run CF using a copper wire but removing the CF and the wire from the camera too many times files would be a problem

When i use dual iso, i get some weird colors every 3-4 frames

4 normal frames


4 weird frames


Am i doing something wrong?

Edit: Vertical Stripes was "Force" turning it off fixed, sorry

[Single]

When i choose Single or Slit-scan shows *preparing* and *beep* but does not capture anything.
