What is Digg?84 Comments
- aurigus, on 10/12/2007, -2/+28In case anyone else is wondering what HDR is:
High Dynamic Range

- Korvaras, on 10/12/2007, -0/+12They've been related since international modern style, and post modernism dude. While they can be seperate, they also can be used in unison in a design.
- rudolphdude, on 10/12/2007, -0/+9Cuz your opinion isn't mine and I think HDR is great. Have a good day!
- beelz, on 10/12/2007, -2/+10there was a store on digg a while back about Tokyo that showed how to do it.
- md81544, on 10/12/2007, -0/+7As long as you can produce several images at different exposures, with no changes to the scene in between, you should be able to get an HDR image out of pretty much any digital camera. A camera with multi-auto-bracketing helps a lot.
- bmobile, on 10/12/2007, -2/+9^ dude, its an effect called HDR...it takes effort to produce images like that.
- hriwo, on 10/12/2007, -3/+9I love HDR photos automatt is one of my favorite photographers on flickr, I only wish I could master it.
- bigpeeler, on 10/12/2007, -0/+6Why'd they change it? I can't say. People just liked it better that way.
- metamongrel, on 10/12/2007, -3/+9what? photography isn't a technology?
- RacerX, on 10/12/2007, -0/+6Here is the Tokyo article with tutorial:

- kevinwiatrowski, on 10/12/2007, -1/+6I get obsessed with getting direct sunlight in my photos. Looking at the great things this guy can do with a cloudy day, maybe I should be obsessed with getting better at my own composition and technical skills.
- ConceptJunkie, on 10/12/2007, -1/+6Um, I don't suppose it's possible that he converted the HDR image to something we can view with our browsers?
Naah. - myskja, on 10/12/2007, -0/+5For those interested in HDR/bracketed photography, here is another one, 6-8 seconds long exposure:

Here is one with exposed hidden detail, manually adjusted for HDR:

3 exposures, bracketed:

- dnder, on 10/12/2007, -1/+5Dude your sarcasm suucks
- m4ktub, on 10/12/2007, -0/+4And here we go with these "Amazing" stories.
http://digg.com/technology/_Amazing_,_digg_,_revealed_:_Top_422_digg.com_attention_grabbing_words
The pictures are nice. I specially like that dark cloudy sky. - rudolphdude, on 10/12/2007, -0/+3Try going a few hours into the day before excessive drinking.
- mrops, on 10/12/2007, -0/+3I have played around with GIMP. There was a nice tutorial on how to do it on at http://www.gimpguru.org/ (for some reason this site is showing me 404 at the moment).
Anyhow, the trick was to put two or more layers over each other and only making correctly exposed parts of it visble via transparancy Mask on each layer. Once done, just merge all the visible layer and you get a HDR image. - finnif, on 10/12/2007, -0/+3Maybe because it's built into Photoshop CS 2?
- RevnCliffie, on 10/12/2007, -1/+4And where are your amazing photos to woo the masses into traveling to NYC?
- Kitsune818, on 10/12/2007, -0/+3I'm not impressed by that wikipedia church photo at all.. It looks unnatural and almost blury.
- agdtinman, on 10/12/2007, -1/+4These are NOT HDR images.
They’re tone-mapped images generated from an HDR image. Seems like semantics, but it’s sort of an important distinction that’s been completely lost during this trend. An HDR image contains the varying exposure possibilities for highlights and shadows, using the starting images you gave it. You can think of it as giving you control over the actual light in different areas of the scene. The tone-mapping process is essentially a way of taking all that HDR information and generating an image that shows all the best-exposed parts. It brings out details in shadows, under-exposes bright highlights, etc. - tuartboy, on 10/12/2007, -0/+3Due to the necessity of multiple exposures (in-camera exposure bracketing is bare minimum and results improve the more images you get (up to a point of course (read: 9-10 ish is typical))), HDR is not well suited to action or even portrait photography. Still lifes and landscapes work well, however.
- samKreuzer, on 10/12/2007, -0/+2It's possible. Shoot in RAW (1 picture). And then in photoshop adjust the exposure times. Create pictures with different exposure times. Finally create the HDR picture with the different pictures.
- TheWalkingDude, on 10/12/2007, -0/+2In case anyone wondered about "New Amsterdam": http://en.wikipedia.org/wiki/New_Amsterdam
- Philbert, on 10/12/2007, -1/+3I agree, decent HDRIs are usually not available for free so this caught my eye. Just to be sure I tried loading one of the images into HDR Shop and it gave me the message "The loaded image is a Low Dynamic Range image [meaning "normal"] HDR Shop needs to convert it to a High Dynamic Range Image".
Check out https://doschdesign.com/products/hdri/ for some collections of excellent HDR images. I use Dosch Skies all the time for lighting my outdoor scenes.
Great looking photos regardless! - myskja, on 10/12/2007, -0/+2You mean camera equipment and such? For those three shots I linked to I used a Canon 10D with a 17-40L lense. I now mostly use a 20D though. And I manually blended the shots together in PS.
- md81544, on 10/12/2007, -0/+2I can see it being a bit of a new fad with lots of HDR-style images appearing (a bit like the incredibly annoying "scratchy LP sound" fad on music tracks we had for a while). However in the right circumstance, it's fantastic. The interior of the chuch in the Wikipedia example image is beautiful.
- maino82, on 10/12/2007, -0/+2yes, theres a completely free program that you can download called photosphere ( http://www.anyhere.com ). the OSX build has a gui, and the other OSs are just a command line tool. it's pretty easy to use once you get the hang of it. if you want to just make pretty pictures, all you have to do is use the tool to compile all the pics into an HDR image. if you want [i]accurate[/i] pretty pictures you need to go through a process of calibrating your camera using a luminance/illuminance meter and a grey card of known reflectance
- tikal26, on 10/12/2007, -0/+2Cinepaint is can do it look here for instruction

They have a linux version and I know they were working on a working windows build called glasgow (their new and improve arch) They were supposed to realese it the 21st, but I don't know what happened, but is at least worth keeping an eye on it if you use windows and cheking out if you use linux. - samKreuzer, on 10/12/2007, -0/+2If you like to create own HDR pictures, try Photomatix.

It's possible to create realistic pictures. Take a look at my pics:

This one is a bit too much :)

For some reason I thought it was hilarious that this sentence ended with the word dude. Large meaningful words followed by valley talk...nice.... - drycounty, on 10/12/2007, -0/+1Very nice. What setup did you use?
- KiltedMile, on 10/12/2007, -1/+2Anyone seen any wedding HDR photog?
- xxdesmus, on 10/12/2007, -1/+2those asre absolutely incredible. wow.
- orangetiki, on 10/12/2007, -1/+2prob just saved down for the masses. But yes the actual raw files are even better. Although I can't remember if it is .raw or not.
- whoutz, on 10/12/2007, -0/+1Composite-Imaging always creates that nasty halo between the images. Its a nice idea but rarely ever looks perfect. I used a GND filter on my camera and that works really great. Here are some pictures I took of the grand canyon using a GND (graduated neutral density). It's basically a square filter with the top tinted 2 stops and the bottom is clear and you can slide it up in down in a bracket to match the scene. Does a transparent job without that nasty halo. They say, its always ebetter to take the beer can out of the picture, than to try to remove it with photoshop. GIMP!

- samKreuzer, on 10/12/2007, -0/+1You are right. Color mapping is used for making the HDR visible.
- bgwynne, on 10/12/2007, -0/+1This may sound like a stupid question, but do you need to have a tri-pod to do this? I'm sure it will make it more effective, but I don't have one, and was wondering if I could still try doing some HDR photos. Anyone???
- tuartboy, on 10/12/2007, -0/+1"Really, the full benefits benefits of HDR can't be seen by the eye. If the HDR image is meant to be seen in the full gamut by a human eye, it has to be "remapped" into the visual range, thereby losing its HDR properties."
My comment from above. - tuartboy, on 10/12/2007, -2/+3you can do that with your pocket camera. It's not rocket science...

I use HDR regularly in maya for hyper-realistic lighting and it is critical in lighting objects to be composited in live action plates. I believe this is where it is most useful. - djblast, on 10/12/2007, -0/+1right click...set as desktop background.
it is stretched a bit, but it works great. - Books, on 10/12/2007, -0/+1Wow, a lot of those are absolutely amazing.
- inactive, on 10/12/2007, -1/+2ummm....was that supposed to be funny?
- ktalinu, on 10/12/2007, -0/+1Another cool gallery http://photos.byethost7.com/index.php?path=Cityscapes/
