http://www.flickr.com/groups/hdr/pool/ - Wyzard, on 10/12/2007, -0/+6HDR is used all the time in movies, actually. I believe they have (expensive) cameras that take HDR pictures directly, rather than having to do multiple shots with different exposure settings. Industrial Light & Magic has even developed a standard image format called OpenEXR (http://www.openexr.com/) and an open-source set of tools for reading and writing OpenEXR image files.
These photos are a strange use of HDR, though. They're taking HDR images (in the form of a set of LDR images at different exposure settings) and squashing them into an LDR final image. That's called "tone mapping" -- adjusting brightnesses in a non-linear way so that you can have a really bright object in your picture without making everything else nearly black, or have a really dim object without making everything else really white. But HDR itself isn't about tone mapping, it's about preserving the true brightness of everything in the original scene.
Take a look at the "OpenEXR Samples" page on the OpenEXR website, and compare the groups of images shown there. If you have access to a Unix/Linux system, install exrdisplay yourself and download the sample photoset. It's pretty impressive -- in photography terms, you can choose the exposure you want *after* you take the picture. - samuelcotterall, on 10/12/2007, -1/+5I Digg because they look awesome.
I don't give one about how simple this effect is, but someone has created some photos that look really cool and that's what matters.
I do fashion/portrait photography which is simpler than this technique, yet people always comment on how much they like my work, and how I have done certain things, so I can't see why there is all the negative feedback from this... - kindrobot, on 10/12/2007, -2/+6Unsexy
- kennyboy019, on 10/12/2007, -0/+4Dodge and burn baby, dodge and burn.
:p - Wyzard, on 10/12/2007, -0/+4I should add that I didn't mean HDR plus this sort of tone mapping, as seen in these photos, is regularly used in movies. It's used mainly to provide greater flexibility in production, I think -- you can adjust the brightness in post-processing to make it look like a sunny day even though it was overcast when you were filming, or even film a scene in broad daylight and make it look like nighttime in the finished product.
It also probably makes it easier to integrate live-action footage with computer-generated elements, since the computer rendering is inherently HDR anyway and you want to match up the lighting so that the CGI elements look like they're really part of the scene. - Glidedon, on 10/12/2007, -0/+4Pretty ironic if you ask me. People using camera techniques that make the real images look fake. And people using Photoshop to make fake images look realistic.
- synaesthesia, on 10/12/2007, -2/+5These pictures are great. I've always thought Tokyo to share some of Gotham's grittier and grimier qualities and these pictures really bring out the misery and despair. Not that Tokyo isn't a great city, but on a rainy afternoon the gray of the sky and concrete turn everything into a soul-draining granite-colored blur.
Too bad they didn't catch the blue-tarped hobo village right behind Shibuya, less than 30 feet away from stores selling $200 t-shirts to spoiled thrifty teenagers. - PercyKittenz, on 10/12/2007, -2/+5That's pretty cool. I'd love to see a movie done in this style, but I don't see a way to build a digital camera that could do the same thing. Maybe they could shoot the scenes and later apply the colors digitally based on these stills? It'd be a neat effect if they managed to do it, however it got done. Kind of like Sin City with the color saturation turned all the way up instead of down.
- vanillapod, on 10/12/2007, -3/+6Lets see you make a tutorial then. It's pretty good as an introduction to HDR.
- brownspank, on 10/12/2007, -2/+5It's never morning in Gotham. :)
- Lacero, on 10/12/2007, -1/+3My Canon D100 brackets to a max +/- of 2-fstops. I've experimented with HDR and using Photoshop CS2 to do some pretty neat effects. I think we'll be seeing some more advances in this area.
- bitcloud, on 10/12/2007, -1/+3theres nothing HDR about these images. They are achieved through the same technique used to create true HDR images, but the dynamic range of these JPEGs (any JPEGs) is 256 levels. A HDR image has many more levels of dynamic range (as many as you are willing to include)
HDRview is the only software I know of for viewing true HDR images: http://www.debevec.org/Probes/
there are also HDR format photos included on this page which allows you to adjust the light levels on the photographs to range from underexposed to over exposed/blown out.
Pretty photos, but no digg. - radu79, on 10/12/2007, -1/+3That's the coolest thing ever!
I wonder how well it works with digital cameras, especially the non SLR ones. - subvertman, on 10/12/2007, -2/+4where is batman?

Even that's not working? - inactive, on 10/12/2007, -1/+3I've been doing this in the film darkroom for years. Takes a lot more time, but the results are more realistic, and more visually stunning.
The object in my efforts is not to look surreal, but just offer enough additional 'information' to make the picture interesting.
I hear a lot from people with better ideas with HDR, but I haven't seen any significant difference.. halos, foggy cut-ins, and over saturated shadows... bleh... - klausbaerbel, on 10/12/2007, -1/+3I much prefer DRI (DynamicRangeIncrease) over HDR.
On Flickr is a group devoted to it: http://www.flickr.com/groups/dynamic_range_increase/ - lollerskates, on 10/12/2007, -0/+2Also, I guess it's better if you're Asian. I would assume that you don't get as many stares.
- AngryPenguin47, on 10/12/2007, -0/+2HL2: Lost Coast utilizes HDR so the upcoming expansion pack to HL2 will probably use HDR as well. w00t!
- Shinglor, on 10/12/2007, -1/+3I agree, these photos don't look very good at all. The first example from Wikipedia looks nice though.
- alexzizka, on 10/12/2007, -1/+3
Its sweet but i wouldn't say Gotham city. Gotham city is all Art-deco architecture, and if you haven't realized it, Tokyo is not Art-deco. - Malakin, on 10/12/2007, -2/+3You don't need AEB. Take a picture, then adjust the settings, then take another picture and repeat for as many pics as you want (obviously a tripod is needed). With most non SLR's the dynical range is pretty bad so the difference between your most and least exposed picture has to be quite a bit for the HDR to work well. I find AEB doesn't usually provide enough exposure range so you end up just doing it manually anyways. I usually just use 3 pictures but the first will be very dark and third will be very bright. If you push the effect too much you end up getting halos around things like this guy did, an effect I try to avoid but it depends on what you're going for I guess.
- Weakling, on 10/12/2007, -2/+3It is not about how simple an effect is, it is about how it is applied. Everyone can apply colors and fonts to a text and it is very easy to do, but that does not mean it automatically looks beautiful. In this case the HDR tone mapping is the easy effect, but it is overdone here imo. Give someone a box of crayons and the first few drawings the person will try to use every color in the box. Over time he will learn to only use the ones that really make the drawing better. Again, it is not about how easy something is, but how it is applied.
- yongfook, on 10/12/2007, -1/+2Any camera that has an AEB (Auto Exposure Bracketing) feature can do this - I think most non SLR digicams have AEB nowadays.
- freedomwv, on 06/17/2008, -0/+1Actaully HDR is more of a super real perspective on reality. It is what our eyes sees. We may not notice that the human eye can actually see the world this sharp but it can.
- blinkgreen, on 10/12/2007, -0/+1those pics look totally awesome!!! i could really get addicted to something like that. you can even make your pics look artistic so that people can think that you're like a genius or something.
- Bhima, on 10/12/2007, -1/+2The typical range of auto exposure bracketing is insufficent
- CypherXero, on 10/12/2007, -1/+2I wrote an article about a year ago, describing how to use HDR in Photoshop CS2.
http://www.cypherxero.net/blog/?page_id=436 - freedomwv, on 06/17/2008, -0/+1Tokyo`s dark side very cool. For some dark Tokyo history google girl in cement. The story will shock you.
- knotty, on 10/12/2007, -1/+2As to doing in with one source photograph - It IS POSSIBLE with a RAW image.
Simply extract a picture from the RAW at -2EV (for example), one correctly exposed and one + 2EV and combine them in a program such as photomatix. Not as good as completely separate photos but it works.
But as Weakling says above, the effect this guy has achieved is pretty easy (just be sure to use a good tripod) and usually what you try to avoid when making HDR images - unless you are going for the 'Gotham City' effect every time.
These examples are better:
http://www.hdrsoft.com/examples.html
And a couple of my own:(using photomatix and multiple exposures is a good way to take photos at night without flash).
http://fishlake.info/pic1.jpg
http://fishlake.info/pic2.jpg
And as to viewing 'proper' HDR images as noted above, you can use HDRView, SPI-V (a panorama viewer made in Shockwave which does Adaptive Dynamic Range - the image is exposed correctly for the area you are looking at, much like the way our eyes work) - and RAW images are a limited form of HDR images too - you can choose the level you expose them at after the fact in Photoshop or similar. I'm sure there are other ways. - Osjpr, on 10/12/2007, -0/+1That white outline hurts badly...looks so much like bad printing technique
- Stockwell, on 10/12/2007, -0/+1-damn first one was in the wrong place--
Thanks Weakling, much appreciated.
Cheers.
The pics have my 7yr old fascinated - this afternoon we're going to do our own first HDR's.... let's hope it turns out into something more or less decent hehe.
Thx again Weakling... ;) - CrAzYKiLa, on 10/12/2007, -0/+1Pretty intersting Article even though im not a photo person , Pictures look a little wierd though..
- Osjpr, on 10/12/2007, -0/+1It's not that it contains too much information. That is a bad emphasis. It's that no electronic device can represent the contrast that our eyes can see.
- Stockwell, on 10/12/2007, -0/+1Thanks Weakling, much appreciated.

Bookmarked for wallpapers. - Stockwell, on 10/12/2007, -1/+1Groovy intro in to HDR
(check out the pics of Tiny Tokyo as well on the site) - SatansMagicHat, on 10/12/2007, -1/+1Anyone have any mirrors to this? The site seems to be congested.
- TheNik, on 10/12/2007, -1/+1I don't see where they got Gotham from, but they are nice pictures none-the-less.
- dolphumous, on 10/12/2007, -1/+1I'll give it a whirl. Thanks.
- maino82, on 10/12/2007, -1/+1It's nice to see HDR being turned into an art, but I'd love to see some more tech articles for us in the lighting business. It's a really great tool to create luminance and illuminance maps of a space. I know most people are talking about using the auto-bracketing feature to do HDR shots, but really if you want to do HDR photography you need much more than 3 shots. Generally 5-10, ranging from extremely dark to extremely bright. You essentially want to get a photo with as close to pure black and as close to pure white in them as possible, then a bunch of ranges in between. From there you can compile them using photoshop or (my personal favorite since it's then compatible with radiance http://radiance-online.org ) photosphere ( http://anyhere.com ). This lets you analyze light levels in a scene provided you have a reference luminance (such as from a grey card of know reflectance). It's fun! try it out!
- dolphumous, on 10/12/2007, -1/+1Is there a way to do this with only one existing picture?
- lollerskates, on 10/12/2007, -1/+1...You mean New York?
It's not that bad here, really. - Weakling, on 10/12/2007, -1/+1It can be faked a bit with some effects yes and if you take a lot more time you can come very close, but it is totally up too you if it is worth the effort. The most quick and dirty way is copy the original to two other images, turn up the brightness and down the contrast of one and edit the EXIF as a minus 2EV picture. Do the reverse on the second copy, turn down the brightness and up the contrast and edit the EXIF as a plus 2EV picture. Load these two plus the original one into Photomatix and you will get an approximation of the same effect.
- PunchMeIBleed, on 10/12/2007, -1/+1wow beautiful
- Stockwell, on 10/12/2007, -5/+5Give us your tutorial then, and see if we'll digg it.
Nonetheless a nice introduction to most people into HDR. So quite whining.
If you say you cando better, please prove so. - llbbl, on 10/12/2007, -1/+1"In computer graphics and cinematography, high dynamic range imaging (HDRI for short) is a set of techniques that allow a far greater dynamic range of exposures than normal digital imaging techniques. The intention is to accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to the deepest shadows.
This provides the opportunity to shoot a scene and have total control of the final imaging from the beginning to the end of the photography project. An example would be that it provides the possibility to re-expose. One can capture as wide a range of information as possible on location and choose what is wanted later.
Gregory Ward is widely considered to be the founder of the file format for high dynamic range imaging. The use of high dynamic range imaging in computer graphics has been pioneered by Paul Debevec. He is considered to be the first person to create computer graphic images using HDRI maps to realistically light and animate CG objects."
http://en.wikipedia.org/wiki/High_dynamic_range_imaging - electronicmaji, on 10/12/2007, -1/+1HDR hmmm is it possible to film in this? It would look sweet to do a movie all in this style kind of like a colorized noir film..
