Hi

Tested the 50D "green" issue. Looks like Windows version has the " green " issue for 50d image, but custom build on Mac shows normal image. Please see comparison of same image

green Windows build:

OK Mac 50D build:

50D Mac cr2hdr Tool can also be downloaded:
http://www.gerstel.org/images/canon/dual_iso/cr2hdr

Then you also need to download dcraw and exiftool:

[make]

Hi,

For me it is also new, but got dual iso tool working. Please use next guide for general setup:

Also install XCode and command line tools:
Xcode menu > Preferences > Downloads > choose "Command line tools" > Click "Install" button

Then ML stuff using next guide:

http://magiclantern.wikia.com/wiki/Magic_Lantern_Development_on_Mac

Then you also need to download dcraw and exiftool:

http://www.sno.phy.queensu.ca/~phil/exiftool/
http://lightzoneproject.org/content/mac-version-new-dcraw-available

Then download sources from Bitbucket, I use Andy's.

Goto dual iso dir and type make. It will give the cr2hdr tool.
If you only need cr2hdr and don't want arm tooling (it is complaining about arm then), you can remove dual_iso.c. Make will give some error, but the cr2hdr will be created anyway and works :-)

Building the cr2hdr tool in a mac environment is super easy. Just follow the instructions for downloading the source repository and a prebuilt tool-chain in the 'getting started with development' thread. Then make in the dual_iso modules folder. It builds both the module and cr2hdr.

Here is the binary built as of Aug 11th. cr2hdr for Mac

This is a command line version. I would suggest making a symbolic link to where ever you save it in /usr/bin so you can run it in whatever folder you save your images. You also are going to need to install dcraw. I installed it using MacPorts.

Thanks a lot, but I get error:

studios-mac-pro:canon studio$ ./cr2hdr IMG_0155.CR2

Input file     : IMG_0155.CR2
sh: dcraw: command not found

got Xcode and gcc tools, I will try to compile on local

Hi is there any Mac version of cr2hdr?

I tried myself with no luck....

studios-mac-pro:dual_iso studio$ gcc cr2hdr.c

Hi, just installed dual iso andy600 build on my 50D, but can not find any CR2HDR tool for Mac OSX. Is there any CR2HDR or alternative tool for mac?

Latest builds for the 50D

Magic - https://bitbucket.org/andy600/andy50d/downloads
Tragic - https://bitbucket.org/andy600/tl50d/downloads

Hi, I moved from ML to Tragic TL and tried latest build Tragic.Lantern-2.0-Andy600build.2013Aug04.50D109.reslock.zip

Thank you very much for performance improvement! Now I get more than 40 seconds 1080p.

Previous ML build June 28 I only got few seconds, so this is very good 

CF card is 64GB Komputerbay

Thanks
Jorgen

Shot RAW on the 5DM3 and 50D using the Magic Lantern Hack. The 5DM3 was shot at 1920x1038 (1.85). The 50D was shot at 1920x1038 resolution in cropped mode to match the 5D. A pair of 64GB 1000X KomputerBay CF cards were used for the shoot. The ratio of 5D/50D is approximately 60/40.  Can you tell which shots are which?

https://vimeo.com/71108800

The RAW files were converted to dng sequences with Rawanizer ver 0.5.5. DNxHD proxies were used to edit the footage in Adobe Premiere CC. Once edited, the sequence was brought into Adobe After Effects CC via Dynamic Link and the proxies were replaced with the RAW footage. First light color correction was done in ACR, and additional corrections were performed in AE. All compositing was performed within AE.  Gorilla Grain was added to the final output.

Very nice 

Does the 50D shoot 1920 x 818 in full sensor mode or do you have to use cropped mode to retain such high resolutions?

Hi
This is filmed in crop mode, 50 mm lens. Full sensor goes only to 1584 width. However using a anamorphic lens works very well in full sensor mode. 1344 x 1058 works continuous.

Filmed 1920 x 818, 64gb komputerbay, duration looks continuous & stable. However format CF card so now & then to keep card fast.

Hi,

Looks like shooting in crop mode has little less moire.

Testing 50D crop mode, now 50mm lens turns into zoom lens!

Very crisp image!

Hi

Today I also did some shoot out to test crop mode, will post later. I always put it in M mode, check my settings and shutter in "photo" mode before record. Also in very bright (sun) light I use viewfinder to check, do the focus and then switch to live view for raw recording. This gives me the best & sharp results. If you don't have any filter then shutter must be set higher than 1/48 in bright light.

One more thing: if your "live view" does not really do what you expect in your setting (shutter, iso etc), goto menu, 6th, Live View function settings, expo simulation: Enable 

hope this helps :-)

Some really nice shots in there sir.

The opening flare was epic.

Is this the Kowa 8Z-alike Bell & Howell? Black barrel?

Yeas very nice anamorphic flares, I like

filmed end of the day with nice sun.

Canon 50D Raw test to check moire in high contrast. You can see moire in the water.
Lens: Kowa 8z anamorphic

Some parts were over exposed, is very hard to see in the display, sorry for that.

Looks great but I think you forgot to conform your footage? Did you shoot with FPS Override on? I downloaded the original and it plays back at 30p and looks a little fast

Yes you are right, I shot at 24 fps in the 50D and somehow in the conversion it has been set to 30. I corrected and reposted, Thanks!

Currently CF card IO is the bottleneck....
Imagine you can solve the 14 to 10 bit issue: this bottleneck is solved and resolutions can explode: what about 5d3 4K camera..... just an idea...

Very nice!

I use Alex 4D plugin, which works really well.

In this video I did not use any FPS override, it is shot in 720p 50 which results in 25 fps HDR footage, due to alternating frame HDR method. There are many artefacts and ghosting in this video, this is to show that HDR can not be used in all situations. In video below no fast left-right camera movements are made, so there are no artefacts.

In this video a short demo is given using ML HDR and Alex 4D.

HDR Video test

Please see HDR test here:

This video is created with Canon 550D, ML and Alex 4D.
It has high dynamic range, but shows artefacts when moving camera sideways. However using it the right way the footage looks very good, thanks ML and Alex 4D to enable HDR video!
