ML ISOs tend to reduce what i recall i called "amplifier glow" (magenta-like glow in the shadows, visible when pushing high ISOs and/or in long exposures). Especially the preamp seems to be the major contributor here. I tried various settings starting from Canon ISO 200, from ADTG only (reduced until WL drop), to 0xFE gain 0 and preamp standard, to 0xFE 0 and pregain 1. Only lowering the pregain reduces the glow significantly.

Only ADTG: https://www.dropbox.com/s/qb09hezgo8crxml/5D3_ML%20ISO%20149_only%20ADTG%20crop.jpg?dl=0

Only 0xFE: https://www.dropbox.com/s/o2a6ebavivq6o79/5D3_ML%20ISO%20137_only%200xFE%20crop.jpg?dl=0

0xFE=0 and pregain 1: https://www.dropbox.com/s/jgls31kr5vfls4f/5D3_ML%20ISO%20110_0xFE%280%29_pregain%281%29_crop.jpg?dl=0


At high ISOs, ML ISO settings tend to clean up the colors a bit, and move the a bit toward green (presumably because the amp glow is reduced):

ISO 3200, Canon: https://www.dropbox.com/s/1ookn81oekq9pvb/5D3_C_ISO_3200%20Crop%202.jpg?dl=0

ISO 3200, ML (pulled from 6400): https://www.dropbox.com/s/afukgac8y90br1s/5D3_ML%20ISO%203200%28from6400%29%20Crop%202.jpg?dl=0


Now lets push the exposure a little bit:

Canon: https://www.dropbox.com/s/pdymz714lpov89u/5D3_C_ISO_3200%20Crop%202%20%28%2B1%20EV%29.jpg?dl=0

ML: https://www.dropbox.com/s/yiq2qdeb4exkq95/5D3_ML_ISO_3200%20Crop%202%20%28%2B1%20EV%29.jpg?dl=0


BTW, is there any way to convert a DNG to ML RAW video or MLV? So that i could try the vertical stripes fix from MLV Mystic to reduce the banding noise?

Not meaning to be impatient, but did the research on this get to the point of making it into a "Nightly Build"?

The info on the introductory OP from Jan, 2014 seems to indicate it is still experimental if someone is willing and able to do a compile from source. Or not?

Do devs need help with testing on 600D at this time?

Yes, any test you find on this thread, that was not done on 600D.

Same for any other camera ;)

I'll start reading through the thread when I'm less busy. Though I don't mind  if I can be pointed to specific test procedures in the mean time.

Updated first post - on 5D3, you may now use the crop_rec build to run these tools (they no longer require GDB).

FYI, the latest adtg_gui contains an experimental 3K crop mode for 5D3 as well.

Been lurking for a while, and have been running ML on my 6D for over a year and love it.  I finally am able to compile on my Mac after a week of trial and much error (I know nothing about coding).  I'm trying to run the ADTG module and edit the registers.  (yes, I've enabled CONFIG_GDB)

My problem is that when I try to run the adtg_gui module, I get these errors:

Quote
tcc: error: undefined symbol 'strstr'
tcc: error: undefined symbol 'patch_hook_function'
[E]failed to link modules

Can anyone help a newbie out?

Try compiling ML core as well from the iso-research branch, not just the module.

adtg_gui.mo - is there new version which is compatible with current experimental branches crop_rec? the currnet link on 1st page does not work with it

No progress? Need any testers for 600D? I could compile and help with some data. I would really like to see this on nightly builds...

Welcome - feel free to experiment and share your findings.

FYI - the raw_diag module is on the downloads page for quite some time.

Cool, thanks a1ex. I'll do some test and send some data...
