50D Super Resolution Dual ISO
« on: November 14, 2013, 05:37:13 AM »
Although my main focus is video I'm starting to love my 50D for photography.

I've been experimenting with photo matrixing, taking multiple shots of interesting architecture around Riga, Latvia.

Here's one of my first efforts (click link below for scaled to HD image):



This shot is made up of 15 x 15mp images (3rows/5 columns). Original composite is around 19000px wide. Shot on an old, manual Auto Revuenon 50mm F1.4 but using ML Auto ETTR. Processed with ACR and Microsoft ICE (for stitching the images)

I hadn't heard of ICE until I went looking and it's fantastic. Beats Canon's photo stitch and Photoshop photomerge. Well worth the FREE download if you're on PC http://research.microsoft.com/en-us/um/redmond/groups/ivm/ICE/


View a scaled to HD size here: http://i.cubeupload.com/BIuArx.jpg


UPDATE: Here is a small gallery with a few more. Shot with ML Dual ISO (up to 70x shots per composite/up to 58k pixels wide) Images scaled to about 3-5% of their original size for web viewing ;)

What a wonderful image. Love the tone and old feel to it. Very nice. I'm intrigued to look into this technique!!
May I ask what aperture this was taken at?

I was using a manual lens but I think it was around F8.

Post a few more shots (used Dual ISO for them) in the first post ;)

Thanks. Yes, that can be a problem with this method. Some shots took me a few mins to complete and people/cars move. I've spent the last few hours photoshopping out disembodied legs and ghost cars. The stitching app is great but not perfect.

Really nice images. I think the subtle HDR look strengthen the autumn mood of the pictures.
The pictures inspired me to use DualISO instead of HDR for my next panorama shooting. Thx

For the Panorama stitching i might recommend Hugin: http://hugin.sourceforge.net/
It's a software the gives the user much control over the stitching process, f. e. it's possible to mask out objects.
It takes a while to get into the possibilites of the programm, but it's really worth it.  :)

Doing panorama photography i really learned a lot from this tutorial esp. with moving objects:

More great captures. Does the dual iso function work with the 550D? It seems like a fantastic feature. I thought the 7D and MKIII were the only two cameras to work with it??

If it works on the 50D I guess it can work on the 550D. It's a module so you could try loading it and see what happens.

U welcome =))) I must say that i start in photo, but then come the oportunity for more afordable video cameras and from there.... i just left photografie for the past... but seeing your photos... it just feel to grab my camera and go to street and shoot some photos... like the old times. Tomorrow i will do that (23:14 right now)    =))

You should! :)

I've only ever been into the video side of things but since ML raw video capability came along I find myself shooting less quantity and more quality. This means I'm out shooting far less video unless I have a specific piece in mind (bored to death with tests TBH). I still wanted to use the camera so I tried Dual ISO and I was instantly hooked. I'm gonna spend a lot more time learning photography I think and it can only help improve my raw video work.

Do post the results if you go on a shoot :)

Indeed  :D  ML have been a school for me, a place... can i say a home?? With raw video i just learn to shoot what i want/need, been more careful about what i shoot. Learning photography will make u a lot better in video for sure. 

Im right now in a place (and without money) that i don't like so much, that not inspired to me to photograph or shoot video but in short time i will move and will take some dual-iso pictures... and of course this will be the first place that i will share it =))

May I ask what are you dual ISO settings?  I'm not sure what I'm doing wrong but my images have a blueish washed out tint and when viewed at 100% the images show horizontal scan lines. I can correct the blueish tint by adjusting the white balance but the photos just doesn't seem right. My set up is 5Dmk3, ML nightly,

It sounds like you're looking at unprocessed CR2 files. They need to be processed into DNG format with the cr2hdr command line utility. I used a1ex's cr2hdr-amaze-edge2.exe for the shots in this thread. There is a download link for the .exe in the Dual ISO thread but you'll need to search the forum for it.

Re: 50D Super Resolution Dual ISO

Sure :)

There's nothing much to the basic look TBH other than using the VisionLog DCP to flatten the images then extreme use of the highlight (sometimes -100), shadows (+50 - +60) and clarity (+50 - +70) sliders in ACR. I wanted a fairly muted, low contrast look with a bit of punch (I know, that sounds contradictory lol). I tend to increase vibrance (+20 - +50) and reduce saturation (-10 - -30) which makes certain colors pop and then increase contrast (using the contrast slider) until the darks feel roughly in the place I want. I then use the curves to increase/decrease the mids and highs depending on what is needed (i.e. to recover more highlight info or increase mid contrast).

I didn't use much sharpening as there can be an insane amount of detail when you stitch 50+ 5k shots and Dual ISO means I rarely need to use any noise reduction. Lastly, I manually adjust WB to either warm or cool the look and use the tint slider if it needs subtle correction.

Once I have a look that I'm happy with I apply it to the other shots that will make up the panorama and export to 16bit TIFFs. I then load them into ICE and let it do it's stitching thing. Hit auto crop and export the stitched file as a TIFF (can be a huge file). I then load this into Photoshop, do a little dodge/burn where I think it needs it (i.e. make the foreground more contrasty), play with cropping (although I'm a bit lazy and could probably compose better), add a vignette and a frame using a NIK plugin and save again as a TIFF and a lower res Jpeg. I did use some NIK color contrast on a couple of these shots and use the plugins a lot for other work but these were pretty much all ACR and Photoshop.

I wasn't too careful when shooting a couple of the panos and missed snapping some foreground detail (road,cobble paths etc) but I just filled the missing sections with the clone stamp tool. The images could be much better TBH but I was just experimenting. I feel quite comfortable with the workflow now so I'm gonna try to shoot some 'for print' panos, night cityscapes etc and spend much longer on post production.

If there is anything specific you want to know just ask. I can upload a few of the ACR presets I created but obviously each shot is different and thy probably wouldn't be of any use.

It is really a good example of why all the megapixels, dr, latitude, dual iso and such don't matter much. Despite all that, those are still horribly composed, randomly framed terrible shots. It seems that it does not even matter if the camera is leveled in those mega-multi-milion-pixels "architecture" shots. No ML feature or other hack will ever help fundamentally bad pictures.

I am really glad you have a good sense of humor and distance to your photos. Nothing that I wrote is against you personally and expresses a general thought about photography, using your photos only as an example. If pictures are bad, it does not matter if they are at the top of one's abilities, involve advanced techniques, technologies, are a result of an experiment or laziness - they are equally bad at the end of the day and as such a perfect example that proves my point, which was all I did. Anyone can love your photos if they want, I hope that saying they are terrible is also ok, it is a great thing that we can disagree.

When that opinion (or more specifically, your point), is provided with no supporting contribution on how the photographer may learn to produce "good" photos in the future, specifically when said photographer advised he would be happy for some tips to improve his composition, what you consider poor, then your posts can only be constructed as trolling.  No more, no less.

I would suggest that your next post in this thread contain helpful information.  Opinions are like assholes, everyone has one!

This method of stitching produces some interesting perspective distortions, like the buildings are leaning towards you or leaning away from each other (kind of the opposite of what you usually see with wideangle architecture photography w/o a TS). Is that just a result of the program you're using to stitch? I wonder if photoshop would give it a different look, there are different perspective options in photoshop, but I've never played around with it much

ICE has a few different options for stitching also (camera motion).

Best results will be obtained where movement of the camera is consistent.  This is quite a challenge hand held!

how much dynamic range do you think you get using dualiso ml without taking more then one shot?
also, is it possible to do dualiso in raw video mode on the 50d? is it possible to stich photos if you have a human on the far left or far right of a horizontal photo?
