I just want to give a huge thanks to everyone working on Dual ISO. I decided to test it out in the video function and here is a quick sampling of it. There are definite circumstances where it really shines and looks quite good in video form. I think it looks pretty good in the first 3 shots. The last shot was really just to see how much dynamic range I could get. All were shot 100/3200, so that maybe the problem with the chroma artifacts in the last shot. I've learned that if a shadow is right next to a highlight, there can be issues. I am really excited to continue to see which scenarios it looks the best in.

For photos, take the black correction algorithm from cr2hdr - it should help. If you upload some samples, I can try it.

A1ex,

I unfortunately don't have the DNGs from this shoot anymore, but I have uploaded a clip to vimeo that shows off what we're talking about. Its barely noticeable in the compressed h.264 version, but if you download the original MOV, its pretty apparent in the dark grey shirt and on my face when I lean forward into a darker area.

I will make sure to hold onto to the DNGs in the future if it happens again to be able to share the originals with you.

Thanks again for all your hard work on the raw module.

are you sure it's the mosaic filter that give the boost? maybe it could be the same with or without?

can you show me some footage please? that would be definitely what could make me buy the 7D. :)

thx

Brawl, Here is a video I did with the Mosaic Filter installed. All the images looked pretty clean to me. Hope this helps.

I just checked on it and Vimeo now says that its converting it into 1080p instead of 720p, so for the moment its just showing SD...? Kinda weird. It should be HD again soon and it definitely looks way sharper...lol.

Update: It should now be 1080p in the embed.

For this test I wanted to try out the new Canon 7D ML raw ability on a longer shoot. The goal was to see how good of a image we could get while also telling a short narrative. All the clips were shot at 1728x972 with a 1000x Komputerbay 64GB card.

The first thing I noticed is that the 7D is still prone to over heating on long shoots. There were times we would stop and dump the footage solely because the camera needed to cool down and was dropping frames or producing too many corrupted frames. Ice packs were used several times. It was Texas in August, but were always in the shade and so this was disappointing to learn that raw recording doesn't produce any less heat for the 7D. I haven't made the switch over to .mlv, but I've read that it produces less corrupted frames, so I will be switching soon.

We shot separate audio and then synced in post. We unfortunately had some issues with it, but this had nothing to do with the ML raw recording module.

The images pretty much speak for themselves. This is way better then anything you can shoot with h.264. Many, many thanks to the whole ML team and all the contributors on the ML Forum.

We used a VAF on the shoot and didn't noticed any moire or aliasing. I did notice some vertical lines especially in the dark grey shirt. Not sure if that was from processing them in ACR or not.

It took me two days to process the footage before I could start editing, so that was a new experience. I edited in FCPX, so after I tweaked the incoming footage, I exported each sequence to ProRes 422 (HQ) then synced all the audio. As long as you use a clapper, this isn't difficult at all.

All in all, the image quality is SO much better then h.264, that I really can't go back. No matter how much more difficult it is to work with (and I'm sure it will continue to get easier) its the only way to shoot with a Canon DSLR for me at this point.

I got the chance to test out the updated raw module today. I wanted to try to get some skin tones in a difficult situation and in an easier one. I used a 64GB 1000x Komputerbay card. The first shot is a mid with the subject partially in the sun and the shade. I forgot that I didn't have my VAF on for the first shot, but I put it in for the second one, which is a closeup with the subject evenly exposed. I've been really impressed with the image that has been coming out of the 7D with the raw module.

All the DNGs were processed in Lightroom. I added some sharpness to try and pull out the detail that was there without going overboard. I recovered the highlights as much as I could. I had to adjust the tint back to 0, and I moved the white balance to about 5000 K. Hopefully this is helpful for someone. Major props again to the whole ML team and all the forum members that have contributed to getting the 7D this far. Lets keep pushing!



It should be downloadable if anyone is interested.

@tiktak There won't be any change in the quality of the DNGs. Like with the other raw capable Canon DSLRs, setting the picture quality to sJPG frees up more of the buffer and hence we get more frames before it fills up.

Hello everyone,

I've been following all the recent developments with the ML team over the last few months, trying to read everything there is. It's a really exciting time for Canon DSLR owners and I want to give a huge thanks to all the developers for their hard work bring this to all of us common folk.

Here are some examples of a few Dual ISO shots that I've taken so far on my 7D. These are both 100/1600. I'm still trying to get the hang of it, but it is an amazing feature.

I'm using the cr2hdr.exe from A1ex's Reply #469
