If the camera's firmware is already Version 1.3.6, it is not necessary to update the firmware. Corrects a vulnerability related to firmware update.įirmware Version 1.3.6 is for cameras with firmware Version 1.3.5. Corrects a PTP communications vulnerability.Ģ.

It's definitely worth reading the PDF just to get the background on what's going on, so head on over to the Magic Lantern forum to check out the document, as well as download the new update.Firmware Version 1.3.6 incorporates the following fix:ġ. The team over at Magic Lantern have done impossible things over and over again, so I don't doubt for a second that literally anything is possible. The new 70D, however, might actually be able to do it since it supposedly has 8 channels. The reason this is possible, it seems, is because of an 8 channel readout in the Mark III and the 7D, whereas most of the Canon cameras only have 4, so they will not be able to take advantage of this update.

It's taking dual readouts from shadows and highlights and combining them in a seamless way very early on in the picture pipeline. This new breakthrough is actually operating in a similar way to how the sensor in the ARRI ALEXA operates. The upside, though, is that it is a very serious increase in dynamic range. This is a major change in the way the sensor is actually operating. Again, this is not like all of the other Magic Lantern advancements that have come before it. I don't recommend this for anyone not willing to lose their camera (at least for now).

The sensor will scan half of the lines at ISO 100 and the other half at 1600 (Figure 2). the answer to this question is the key to some massive improvement in image quality. What do you think it will happen if we change this register to 0x403 or 0x043? So, back to our CMOS register #0, it looks like the LSB nibble is probably some flag, and the other two are some sort of amplifier gains. In LiveView, the gain is only applied to the YUV image (it does not affect the 14-bit raw data at all), but in photo mode, the gain is burned into the raw data. These ISOs are obtained by applying some digital gain to the raw data acquired at the nearest full-stop ISO, and this gain is configured from the DIGIC register 0xC0F08030 (SHAD GAIN). Here's a little taste of that:Īs expected, intermediate ISOs like 160 or 250 do not cause any changes in ADTG/CMOS configuration. This may never be something you use on a daily basis because of these issues, but for some instances, if you need the dynamic range, this could work very, very well, and there won't be the strange motion issues that come from HDR and combining pixels.Ī1ex has written a mathematically dense but extremely informative PDF explaining the situation and what was done in order to achieve this as well as how the images can be processed to look better. You are more at risk for aliasing and moire since the sensor is now being sampled differently, and you're also losing 5x and 10x zoom to check focus. You also are losing some resolution with this mode, as you are halving resolution in the highlights and the shadows. My 5D3 is still alive after roughly one week of playing with this, but that's not a guarantee. Therefore, it's safe to assume it can fry the sensor or do other nasty things. In the technical doc you can see how this method messes with the feedback loop for optical black, for example.

This code changes low-level sensor parameters. This is not something you want to mess around with lightly. This is a pretty serious change in the way the camera is exposing a normal image. So what are the downsides? For starters, this is not like Magic Lantern RAW, where the team has simply grabbed what the camera is already doing. To get a natural HDR look: try my automatic color grading script. For RAW video files: latest raw2dng.exe. It requires dcraw and (optional) exiftool in your path. For CR2 files: cr2hdr.c (Windows: cr2hdr.exe).
