Wow,
Check this out!
By utilizing a feature set that Canon has never accessed, the team over at MagicLantern have managed to get 14 (yes 14) stops of DR out of both the 7D and the 5DmkIII.
Apparently, they're setting some lines on the chip at ISO100, and other lines at ISO1600, only possible on these two bodies because apparently they're the only ones with two independant amplifiers.
Very interesting stuff.
Check out those shadows!

and...
Warning
This code changes low-level sensor parameters. In the technical doc you can see how this method messes with the feedback loop for optical black, for example. Therefore, it̢۪s safe to assume it can fry the sensor or do other nasty things. My 5D3 is still alive after roughly one week of playing with this, but that̢۪s not a guarantee.
We don̢۪t pay for repairs. Use it at your own risk.

Who here uses MagicLantern? If I tried it out, what are the chances I would screw something up? |

i use it on my 50D. mainly for the ability to shoot video. i've never had a problem with it. |

you cant brick your camera, its loaded off the memory card, its kind of like dual booting the camera firmware, if you dont like it or prefer not to use it as i did, you simplly delete it off the card and you go back to the using old firmware.
the only problems that could really happen are spelled out in the warning above where the hardware is attempting to to do something unintended and *could* break something, its highly unlikely. for instance the 50D, by default cant record video, so it would not have been surprising to see an issue with the sensor overheating (note that inst the case as far as i'm aware, it was just an example) where the the newer bodies who can record video with the stock firmware have failsafes in place to prevent it or the sensor design is different.
magic lantern is so popular and most problems have already been hashed and if you give the new features like this a few weeks they will get vetted to. |

Hasn't bricked my gear yet.

jeebus. that looks promising. |

Interesting turn of events... the issue, at least in the near term, is that the RAW development algorithms need to be customized for it. I downloaded the RAW file for the 5DIII still image, and the result in ACR is really funky looking. Specialized demosaicing algorithms are an absolute requirement. |

This one actually is potentially higher risk, given what they are playing with. Still, I think the risk is relatively low. The pain if bricked, however, would be serious! |

I use it on my 60D.
The two features I have playing mostly with are
1. Auto Focus Stacking - Pretty neat for macro work. You specify the near focus point, far focus point, number of shots and it does it's magic.
2. Exposure Bracketing - You can specify the number of exposures and the step range. Nice for HDR work. |

True enough, but it's not like they're doing anything more than adjusting two amplifiers independently, or overdriving the chip or anything, ISO1600 isn't exactly high on either of these bodies.
Hell, I'm seriously considering moving from my 50D to a 7D just for this reason..... |
