Indeed.

Kudos to @a1ex for updating the 20-bit cr2hdr & @N/A for making this possible on Mac. [emoji108]

Thanks for sharing @chris_1975 and the hot pixel fix is just marvelous!

I used Dual-Iso to take all of the images in this album. They are not great photographs and I processed them in a very contrasty way though, so it can be hard to tell, but the difference between regular cr2 files and Dual-Iso files are really dramatic.
Any Canon 650D owner probably knows that that the noise levels of this camera is a pain in the ass, especially when you try to pull the shadows even a tiny bit.
Dual - Iso sorted all of these issues for me. So whenever there is no tripod around, Dual-Iso is on.

Latest Dual Iso Picture :)

Zeiss 35mm

100/1600 ISO

Converted with Photoshop. Love the dual iso feature even for black and white images. So much control over the light!

These two images were shot on a trip to Lisbon, where I was taking all of my images with dual iso feature turned on. At first I was a little afraid, that I would end the trip with about 500 unusable pictures, but they turned out to be far better than I thought they would end up being. I won't do it again though. Using dual iso I realized, that in most cases I won't need it. Mostly it looks unreal and unpleasing to push the dr too much. I'm a total fan of subtle effects in that matter. So most pictures I ended up grading normal in a way I could have done without dual iso. For certain situations though I like it. The best thing about it is, that you can adjust the lighting in post, without having to think too much about it while taking the images. Taking a proper exposure in the first place is of course the far better option, but for spontaneous pictures, where you have to rely on camera metering, it can be a blessing to have it turned on.

I like those bw pictures very much. Well composed.

Jazzepisode

Thank you. That means a lot to me :)

One virtual copy created from the original dual iso -file and then blended together in PS with luminosity masks :)
I really need to get back to taking pictures this summer, haven't had inspiration in a long time unfortunately!

Where is that picture from? Surreal architecture.

Jazzepisode

That picture of mine? From that same trip to Lisbon. It is a part of the train station Lisbon oriente built by Santiago Calatrava. It is part of the architecture exposition from 1998.

I've experimented a bit with Dual ISO on my Canon 60D, not with any great success. I am primarily looking to reduce noise in shadows. First time I tried it with a high-contrast area, it had bad sawtooth artefacts in the transition, which I think A1ex subsequently fixed according to a post. I just did a quick test today when out, a shot from within the car on a sunny day. All I see is the reduced resolution, no gain in quality. I would still like to experiment with the method using 2 brackets on a tripod, but I have to change ISO without bumping the camera.
Here's a crop from my experiment using a Canon 60D with Magic Lantern Nightly.2015Jan24.60D111 and Dual ISO set to 100/1600 and decoded using the Mac version of cr2hdr 2.0 Beta

Could you make the picture smaller? I think 900 pixels is maximum allowed.

Done. Added link to full-size image, as the detail and noise levels are rather the point.

Hi guys!

I have done a small trip in Asia and since every picture in this flickr is Dual ISO even the small time lapse It's a pleasure to share with you.

Hope you like it  :)

Thank you ML

Danne

Very nice pictures micbil. What settings and what converter did you use to trasncode them? Thanks for sharing
