We’ve been shooting at 100/1600, 400/3200 and 800/6400 and we find the results to be rather well balanced. One thing to keep in mind is that the bigger the gap between your two ISO values, the lesser the dynamic range will be in the midtones. The first ISO value is something you set on camera, through the ISO button on the top and the second ISO value is done from the Magic Lantern menu. A green dot next to the option means the setting is enabled. Once in the menu, browse over to the “Expo” menu and go to the Dual ISO option and press the set button. Once you do that, you should bring up the Magic Lantern menu by pressing the delete key. In order to get your camera to shoot photos on Dual ISO mode, you need to ensure that the video toggle on the back of your camera is set to photo mode. This will help keep your workflow very streamlined (and avoid conflict between files). We extracted the video stuff into a folder named Video Work and the photo files into Photo Works. Extract the contents of the respective zip files into separate folders. You can download CR2HDR (the photo module) from here and the video module from here. You will need two separate modules, one for video and the other for photo, to achieve this. They first need to be “normalized” before you can do anything usable with them and for that, the ML guys have written custom code. Unfortunately, since the custom firmware is altering the way the CR2 (RAW files) and the movie files are being created, normal RAW converters or video editors can’t do much with them. We recommend a powerful system to handle the task, something that can easily run Adobe Premiere AND Photoshop side-by-side.ģ) The process is somewhat time-consuming, so you might want to refrain from shooting a wedding or any other bulk-image assignment using this technique.Ĥ) Magic Lantern Nightly Build CFW for the 5D Mark III is HIGHLY EXPERIMENTAL and should be used with extreme caution as neither we, nor the Magic Lantern guys take responsibility if you fry your sensor. While you gain a few stops of dynamic range, what you also gain is moiré and aliasing.Ģ) The process of converting the footage and CR2 (raw) files into something usable is quite intense. Before we begin, here are a few disclaimers.ġ) Since this entire custom firmware deal is major hackery, there is some degradation in quality.
