Magic Lantern has long been a fan favourite to “unleash” the features of Canon cameras we wish they had. Lately this has included pushing what we can get out of the sensor.
As reported on Planet 5D:
“Tests have been done by ‘Marsu42’ of CanonRumors, which show numbers of up to 15 stops of DR when using this feature combined with the ‘dual_iso’ module that Magic Lantern already includes in their nightly builds.”
This means that for example on 5d3, iso 800 with ML has more dynamic range than iso 100 with Canon :-> … and at high iso you’re getting 7% more dr which is nothing to sneeze at, esp. since it builds upon Canon‘s advantage vs. Nikon: d800@6400 = ~8.3 & 5d3@6400 = ~9.4 ev. According to sensorgen.info the 6d should add another 2/3 stop (once the code is adapted for it) making good ol’ Canon the superior sensor for low light high contrast shooting.
Since this is a new software update I’d recommend you proceed with caution, however, these are exciting results for both stills and video shooters!

The folks at Magic Lantern have no cracked the EOS 5D Mark II and EOS 6D and made the cameras capable of shooting in “dual ISO mode” which increases dynamic range to 14 stops. We’ve seen this previously for the EOS 5D Mark III.

A video showing the difference between normal RAW and Dual ISO RAW can be seen below. Take a look at the shadow noise reduction in the Dual ISO RAW example, pretty remarkable. The person that made the video did so in a “worst case scenario” way, so your results should be dramatically better if you’re actually trying to make great video.
In case you missed it, this is part of Magic Lantern increasing the dynamic range of the EOS 5D Mark III and EOS 7D by 3 stops using a dual ISO technique. You can read about it here.

The Magic Lantern team is letting the world know that they are at the beginning of a new function for the 5D Mark III and EOS 7D. Apparently they’ve figured out a way to boost dynamic range by 3 stops by using a new way of making a photograph by using ISO 100 for some of the vertical lines and ISO 1600 for the rest of it. Sounds wild to us, not sure how they’re doing that. There will be a process to combining the lines of 100/1600 ISO to give you the full resolution file.
From Alex at ML
- Works for both photos and raw videos on Canon EOS 5D Mark III. On Canon EOS 7D, photo only (since it can’t do raw video).
- What are the benefits? more dynamic range (less shadow noise).
- The functionality was not really in Canon firmware, but in the chip that samples the sensor. Canon firmware does not make any use of it (they just set both ISO “registers” to the same value). It was implemented on the hardware side though (and that’s why it works only on these 2 cameras, because only they have two ISO amplifiers).

Magic Lantern is onto something…
There have been a lot of posts lately about Magic Lantern’s breakthrough enabling RAW video recording on the Canon EOS 5D Mark III.
Below is an ISO test of the standard H.264 of the 5D3, and what the RAW video from Magic Lantern looks like. This was done by Dustin J Tolman.
The results are pretty remarkable and easy to see, this software is still in its early stages and will probably get a lot better over the next few months.
An ISO test comparing Canons H264 compression vs Magic Lantern’s 14 Bit RAW hack.
• First I converted the RAW files with ML’s raw2dng.
• Next I dragged the files into Photoshop which opened up Adobe Camera Raw.
• I selected the first image and used the auto white balance setting which got rid of the heavy magenta tone.
• Then I synchronized the additional files, and exported them as 16bit tiff files.
• First I tried to use QuickTime 7 to create an image sequence, but it render the video with incorrect color.
• So instead of QT I ended up using Final Cut Pro X to create an image sequence to a ProRes 422 HQ output.

Are you covered if you use Magic Lantern?
DIY Photography did a great article on third party firmware and whether or not it voids your warranty. They did it for various brands including Canon, Nikon and Panasonic. Of the three, only Canon is “okay” with you using third party firmware and your warranty will not be “voided”. The only catch is if you “brick” the camera and it’s related to third party software, Canon will not cover that repair.
“There is no such thing as “voiding” the Canon warranty, there are simply repairs that are covered, and those that are not.
For instance, the repairs for a failure of the buttons on the back of the camera within the warranty period, on a camera that does not show any evidence of mishandling or misuse, would likely be covered. Repairs for a camera that is “bricked” or otherwise having issues directly related to using a third party firmware would not be covered.”
Canon doesn’t mention anything about EOS-1 bodies and third party firmware in the above story. However, I have been told Canon would take legal action against anyone publicly releasing unauthorized firmware for the EOS-1 bodies, so this is probably why we haven’t seen any development of such software.

Canon EOS 50D Cinema Camera!
Magic Lantern has made it possible to shoot RAW video on the 5 year old Canon EOS 50D. The forgotten 15mp APS-C predecessor to the EOS 60D.
The software is very early in development, but at least one person that has shot with the camera and firmware is quite impressed. EOSHD notes that the camera has hardly any moire or aliasing in early tests and the ISO performance is terrific. The larger pixels on the 15mp sensor really do make a positive difference over the 18mp sensor that we’ve had for years now.
Below is a bit of information of what works well with the current software on the EOS 50D.
Resolution & Performance.
Results (24 fps):
1592×1062 – frame skipping after about 50 frames (67.7MB/s)
1592×840 – frame skipping after about 480 frames (53.5MB/s)
1592×720 – no frame skipping (44.3MB/s)
1320×1062 – frame skipping after about 300 frames (56.1MB/s)
1320×960 – frame skipping after about 1200 frames (50.7MB/s)
1320×840 – no frame skipping (44.3MB/s)
1280×1062 – frame skipping after about 250 frames (54.4 MB/s)
1280×960 – no frame skipping (49.2MB/s)

A busy week for the folks at Magic Lantern. First they hack the EOS-M, now they have made available the alpha 3 version of the 5D Mark III firmware.
The following feature detail is from a1ex from the Magic Lantern team
The most important change is a card test executed at startup. My 16GB (Kingston 266x) card has problems, and I’m trying to diagnose the issue: maybe it’s just my card, or maybe it’s related to this. If the test fails on your camera, please report.
There are also a few handy tweaks:
- Histogram and waveform moved to bottom
- New experimental display for focus peaking (extreme sharpness)
- 16:9 bars for anamorphic preview
- Focus box moves faster (not yet customizable)
- After taking a picture and pressing Zoom In right away, you can scroll through pictures
- Saturation boost when adjusting white balance
- Warnings for bad settings (e.g. if you set picture quality to JPEG instead of RAW by mistake)
- Dim the red LED while recording (make it less distracting)

… and again
It seems the Magic Lantern team cannot be stopped. They have successfully hacked the Canon EOS-M and plan to port the software to the EOS-M in the coming months.
You can read all about it and its progress on the Magic Lantern site.

Not included in the April update?
I’m wondering aloud if we’ll see the blinking red AF point firmware update for the EOS 5D Mark III before April?
Maybe the recent clean HDMI out software from Magic Lantern forced their hand.
