I've got a 5D3 build here.

Everything goes into the 'modules' folder, except for the autoexecbin which goes to the root folder of the card, right?

Also, when this newest build is on my card, there is a possibility to shoot normal video(without the double iso thing), right?

Sounds right for the file locations. I believe H.264 video shouldn't be changed and you should be able to disable the module, but there's only one way to find out. I would experiment with it tonight, but I don't dare try something this new the day before a big shoot.

Hopefully reg addresses are the same on 6D. I need a reliable way to figure those out.

Dear A1ex, your team work is effortless, generous and FREE. I wonder how come we see people here complaining a new funcionality does work on this or that model. I here to say, I deeply thankfull for the work you do even if my camera is not able to new funcionalities just because there are people like you and your team putting hours, knowledge and inteligence to the benefit of all of us. THANK YOU MAGIC LANTERN!!!!

Amazing stuff as always.

A1ex hacking sensor to its roots is really good. Can I expect RGB Raw output from sensor now?

I want three RAW files for one click. Red RAW, Blue RAW and Green RAW. Sensor recording for only one color per RAW file and producing 3 RAW files.

We have Foveon sensor technology from Sigma that has 3 layered sensor. Each layer is dedicated to just one color. Can we mimick it with ML now.

For those wanting to see a test of the Dual ISO feature in use, I put together a video comparing normal raw video and video shot using the new Dual ISO feature. More details and testing methods used can be found at the Vimeo link... http://vimeo.com/70459941.

Wow, this is quite exciting and impressive. How dysfunctional of canon to not exploit the fact that they'd basically made a camera which can capture a true HDR image in one shot.

It should be possible to do some quite sophisticated denoising of the iso1600 image guided by the data in the iso100 one.

Updated cr2hdr.exe, works for me under Wine. The dependencies (dcraw and exiftool) are included in the zip file.

I've got a 5D3 build here.

Does this one work on firmware 1.2.1?

Lichtgestalt · « **Reply #59 on:** July 17, 2013, 09:27:26 AM »

Dears, I'm sorry for maybe stupid question, but I really want to know..
Is it possible to read one shot twice? I mean - read sensor at iso 100, save it to buffer, and immediately read the same data at iso 1600? For CCD sensors it is definitely impossible, but for CMOS sensor it is not so obvious. So could you please help me?

Hi,
is possible postprocessing dual iso's files on mac with raw2dng?

Yes, has to be consumed with WINE.

What about 720p 48p? A1ex would that be a way to get around the lineskipping?

Yep wine for now until scrax has the time to update the mac raw2dng.

sebamax · « **Reply #64 on:** July 17, 2013, 09:49:35 AM »

Grazie Walter,
think will be possibile compiling an update to raw2dng ?
I hope in scrax

isnt the whole point of raw to record the entire RAW image the sensor sees? and isnt iso on the canons just digital gain? So how if this gaining any DR over just shooting raw if iso has no effect on raw?

Audionut · « **Reply #66 on:** July 17, 2013, 10:00:26 AM »

Ouch.

Reducing the image size to around 33% all but eliminates the problems in the tree. But the power line is beyond repair.

a1ex · « **Reply #67 on:** July 17, 2013, 10:05:51 AM »

Here, a different interpolation method may give different results. Try choosing another one (in cr2hdr.c, there are some defines at the top).

I guess plain averaging will handle this one a bit better than medians.

The real point of RAW is to be working with uncompressed footage in post. My understanding is this technique is like hdr at the photosite level and of course ISO affects RAW - try using footage shot at 6400+

Keeping my fingers crossed for Scrax to come through. This is beautiful work!!

Can you use this module with the 5D Mark II and where do I find it?

Walter Schulz · « **Reply #73 on:** July 17, 2013, 11:28:06 AM »

First post in this thread, third line. End of it.

Good news for the 7D owners. Thank you Alex, we appreciate your efforts
