ico, it is "normal" that the card LED flashes every x seconds when Ml is loaded. I don't like it either, but there's nothing one can do but uninstall ML.

Wow what a ton to read thru, but 7D raw video is worth it !!   

Well, in my opinion, this is a mess. One shouldn't have to read through nearly 60 pages of forum posts to get something working. I hope some day soon the core ML devs will advance the official development and release new, official, alpha, beta or stable versions!

Looks like most of these files are .exe, anyone have a how to link for mac users ?   

Here's a how to for the Mac: http://www.magiclantern.fm/forum/index.php?topic=7752.0. Note that it uses an outdated build, though. But I don't have the time to read through half the ML forum to figure out which build to use, where to get it and how to install it. So I'll just wait for the next official build.

Hi,

I have been playing around with dual ISO on my 7D. I was able to shoot some pics and convert them to DNG with cr2hdr. However, it seems the DNG-files created by cr2hdr aren't completely well-formed. The Preview app on my Mac, as well as iPhoto and Aperture should be able to open or import DNG-files. However, it turns out they can't read the files created by cr2hdr. From what I've read on the forum, I understand that Lightroom also isn't able to open the files, but Photoshop is. (But I don't have the Adobe apps, so I can't confirm that.) I've also tried GIMP, but that didn't work either.

I tried converting to JPG with ufraw-batch, but that gives very dark images with no details in the shadows. Besides, when converting to JPG, I loose the dynamic range, so that isn't an option anyway. I'd like to import the DNG's in Aperture, to be able to store them in Aperture's library along with all my other CR2's and edit them in my normal workflow.

Does anyone know a way to get Dual ISO images into Aperture without losing the RAW-data? Or is there any chance someone would be able to fix cr2hdr, so that it creates well-formed DNG's. (Note that you don't need Aperture or iPhoto to test. The Preview-app, which is part of OS X, uses the same RAW-reading technology as the other Apple-apps.)

PS.
I even tried to compile cr2hdr myself yesterday, with the latest sources from Bitbucket. I managed to compile it and it works, but gives the same unusable DNG-files.

before i do it I want to know if there a way to uninstall it if i don't want it or if I sell my 7D

Hi jsoucy,

Yes, you can uninstall. As mentioned earlier, you can use bootoff.fir to disable the bootflag. Then format your CF-card and no trace is left of ML. Good luck!

I'm not sure if that is a good idea to save tiffs to Aperture. You then save not raw (CR2 or DNG) but already processed file (TIFF) even if it is 16-bit which increase size of file.

You're totally right of course. The thing is: Aperture cannot read the DNG-file. (I also tried GIMP, but that wasn't able to open it either.) So: I know using TIFF is suboptimal, but it's still better than no image at all!

Hi ChrisContiPhoto,

Yeah, the information about the 7D-port is a bit "fragmented" and unclear at times. This thread is an attempt to fix that. If you want RAW video and Dual ISO, you'll need the 2.3-version from the zip-file that is linked in the start of this thread. And that one works with autoboot. AFAIK, there is no way to fix that, but I'm not a ML-guru, so I may be wrong about that. What I know is:
- There is a bootoff.fir file included in that zip-file. It should be possible to reset the bootflag of your 7D with that, thus disabling autoboot for the camera. (I haven't tried this myself.)
- You can work with different CF-cards: if you don't make a card bootable, your camera will work with Canon-firmware if you're using that card. So If you'd like to switch between ML and Canon-only, I'd suggest working with different CF-cards. Then all you have to do to enable or disable ML is putting another CF-card in your camera.

Hope this helps...

Hi everyone,

I've started a new thread with instructions for Mac-users: http://www.magiclantern.fm/forum/index.php?topic=7752.0

Ok, it works. However, I still need to convert it to a TIFF with ImageMagick, because Aperture does not recognize the DNG.

Hi LOGAN570,

It doesn't work for me, here's the log:

Code Select Expand


BK_11395 File Supported
sh: dcraw: command not found Error: BK_11395.CR2 Input file : BK_11395.CR2
THE END


Am I doing something wrong?

[Software Installation]

Hi all,

It seems my Dual ISO postproc instructions were not too clear. So here's a new attempt, a little bit more verbose...

Software Installation
1. Download the cr2hdr tool from here: https://www.dropbox.com/s/4uvrwzmy740a90b/tools.zip.
2. Unzip the file. You now have a directory tools inside your Downloads folder.
3. Open the Terminal.app program. (You can find it in the /Applications/Utilities/-folder.)
4. Type cd to change directory to your home-directory.
5. Type mkdir bin to create a directory called bin, in case you don't have it already.
6. Copy the files from the tools-directory to it. This can also be done in the Terminal: cp ~/Downloads/tools/* . (Don't forget the last period.)

You'll also need to have the following programs installed. Please follow the installation instructions on their respective websites:
- ExifTool
- ImageMagick
- ufraw

Conversion process
1. Copy the file you want to process to your Desktop. Let's suppose the file is called IMG_0002.CR2 for this example.
2. Open the Terminal.app program. (You can find it in the /Applications/Utilities/-folder.)
3. Type cd ~/Desktop to change directory to your Desktop-folder
4. Type ~/bin/cr2hdr IMG_0002.CR2 to convert the image to an HDR DNG-file.
5. Type convert IMG_0002.DNG IMG_0002.TIFF to convert the image to TIFF. (In case you are able to open the DNG-file in your favourite editor / photo manager, you can skip this step.)

I hope it is a bit more clear now. Good luck!

[Using Dual ISO on a 7D - postprocessing on a Mac]

Using Dual ISO on a 7D - postprocessing on a Mac

To post-process a dual ISO image on a Mac, you'll need the cr2hdr tool. It can be downloaded here: https://www.dropbox.com/s/4uvrwzmy740a90b/tools.zip. It can be called from the Terminal, as follows:

cr2hdr IMG_0001.CR2

Note that cr2hdr uses ExifTool to copy Exif-data, so make sure you have that one installed.

This will give you a IMG_0001.DNG-file. I was not able to import the DNG-file into Apple Aperture. So I searched for a work-around, which I found, using ImageMagick. You have to install both ImageMagick and ufraw to use this work-around. Once both are installed, you can use the following command to convert the DNG to TIFF:

convert IMG_0001.DNG IMG_0001.TIFF

Good luck!

[Installing ML on a 7D using a Mac]

Hi all,

I've just installed the latest and greatest 7D-build on my camera, using my MacBook. As I found the installation instructions for Mac users a little hard to find, I thought I'd share my experiences with you. I hope other Mac-using 7D-owners will appreciate my summary. Here we go...

Installing ML on a 7D using a Mac

1. Preparation
a. Download a ready-made Mac-installation kit from here: https://www.dropbox.com/s/prhvvukktwn3wfz/7D.zip (Thanks, DenJS!)
b. Unzip the file if it isn't already unzipped. You should now have a folder called 7D, containing the following files:

- booton.fir – patched firmware which will enable boot flag in your camera
- bootoff.fir – patched firmware which will disable boot flag
- 7D000203.FIR – original firmware 2.0.3
- MacBoot.class – java application wich help you make your CF card bootable
- run.command – shell script to run java app properly.
- To root CF card – a folder containing the ML-build.


2. Enable the bootflag in your camera:
a. Take an empty CF-card, put in in a card-reader connected to your Mac and copy the booton.fir-file to it.
b. Put the CF-card in your camera and turn the camera on.
c. Open the menu, go to the 3rd yellow tab with the wrench-icon and choose the last option: "Firmware version 2.0.3"
d. Choose "Update firmware" and wait a few seconds. The firmware-update-program will start and after a few seconds you'll return to a black screen.
e. Now turn off you camera and eject the CF-card.
f. Remove the booton.fir-file from the CF-card.
g. Re-install the 2.0.3-firmware: follow the same steps as before, now with the 7D000203.FIR-file.

3. Create a bootable MagicLantern-card:
a. Put the CF-card in the card-reader.
b. Start the MacBoot-program, by double-clicking on the run.command. Enter you password if asked.
c. In the MacBoot program, select the size of the CF-card which you inserted and press Reresh.
d. Select Make DSLR-bootable and press Prepare Card.
e. Now copy all files from the folder To root CF card to the root of the CF-card.
f. Insert the CF-card in your camera and power it on.
g. You should hear a beep, indicating that MagicLantern has booted. You're ready to go! Press the trashcan-button on your 7D to enter the ML-menu.

Not booting?
Please make sure you have copied the files from the To root CF card-folder. If you have a bootable card, but not the files in the root folder, the camera will "hang" until you remove the battery.
