I think I prefer the second one, mainly because the halo around the tree in the upper right on the first one stands out too much. How many shots did you bracket for this?

I don't like the way the car looks, it's too blue. You may find that it will look better if you do a saturation adjustment layer with the car masked and the blue saturation down to zero. (Does that make sense? It's ahrd to explain.)

I've never been able to make an HDR image that I'm happy with, I guess I'm more of a naturalist and t's difficult to get a real looking HDR image. Are you using photoshop, photomatix or something else?

Either you are going too crazy with the tone mapping or your pictures have too much dynamic data loss (look at the specs on the sky). And you are over-sharpening the final shot as well.

HDR image should come out looking like this:

http://www.clubna-t.com/gallery/albums/userpics/10001/hdr12.jpg

I shoot in RAW mode to lose as little dynamic data as possible, I found it better to manually find the ideal exposures rather than just bracketing.

Can someone explain, in non-photo-geek terms, how to do an HDR photo?

Ronald Mcdonald
09-21-2007, 05:09 PM
If it helps, I'm using a Nikon D40, and have Photoshop.

DareDevil
09-21-2007, 05:35 PM
Well, you need photoshop CS2 or higher to do it, so i hope thats what you are currently running.


Alright...

First, it's important to turn off some automatic exposure features so that you have full control because you don't want the variation introduced when the camera automatically adjusts exposures between each shot. First, determine the correct exposure for the overall scene and set it manually. If you're camera is normally on Program (automatic) mode, point the camera at the scene and note the aperature and shutter speed, then turn the dial to Manual and select those exposure values. Next, turn off Automatic White Balance by setting it to a specific temperature or icon such as Sun or Cloud.

Generating an image series for HDR works better if you have a tripod because you'll want avoid the slightest shake or variation between shots. It also works better if you have more than 3 shots to combine, perhaps as many as 7 or 8 even.

I dont know about your Nikon, but most SLRs have menu options to do auto exposure bracketing (AEB) of 3 images, so try using that feature as the foundation for creating and HDR image rather than trying to manually fumble with shutter speed in between.

To take a series of photos with the camera's AEB feature, I could set AEB so that each expsoure is about 1 stop apart, such as -1, 0, +1.

...set the camera for multishot so that when you depressed the shutter button the camera automatically snaps 3 images in quick series.

If you have a tripod, then you should try 6 to 8 exposures per series, each with about 2/3 or 1 stop apart, like... -3, -2, -1, 0, +1, +2, +3.


Ok, so now, just click, hold down, and try to stay perfectly still until all the shots are done. Doing this yourself, you should hear a rapid 'click-click-click'. BUT, if the lighting is darker, then the second and third shots will be noticibly longer, so you get a 'click', 'cliiiiiiick', and 'cliiiiiiiiiiiiiiiiiiiiiiick' in a row. Without a tripod or camera rest, for the third exposure to come out well its very important to control the camera and keep it very still.

Open Photoshop CS2 or higher to get started.

choose File > Automation > Merge to HDR.

On the pop-up window click Browse to choose the files you wish to merge.

Click the checkbox to align source images. (helpful if there is a shake)

Click OK and wait a minute or two, and you will be shown a preview.

Adjust the slider under the histogram for Set Whitepoint Preview until you're happy with the result.

You might be happy with the image here so you could save it as a JPG with the quality Level of 12 (highest), or you can work on it more.


There are also TONS of tutorials that may be easier to understand if this isn't explained well enough for ya.

nvm. i downloaded cs2. i went to try out hdr and when i did, after i browsed both pics because i only used 2 that i had, it said " there is not enough dynamic range to constuct a useful hdr image" can someone please explain to me what this means and why it comes up.

It's basically telling you that you only used two.... HDR means High Dynamic Range, in the two pictures you have there isn't enough range...get it? It's best to have atleast three or more. Hope this helps.

Also after you have set the point on the graph the is another area where you can change the tone and gamma and stuff. This is how you can make some pictures "glow" sometimes (like the sky around the trees in Kirk's pictures). Lemme see if I can get some screen shots...

He is talking about setting the exposure. 0 is a "good" regular picture, -'s are underexposed (typically darker) and +'s are overexposed (really light)

What kind of lighting do you need for HDR?

Every picture I have seen is done outside, so is that the best location for a quality HDR picture?

It's not the lighting as much as the seperation in exposure (like Daredevil said)... also probably most of the HDR images you see are of cars, and they're normally outside (hahaha).




I've got some screen shots ready (waiting on photobucket)...

DISCLAIMER: I am not a professional and never considered myself to be one. This was put together by me to help better explain my findings with others, If something is wrong, please inform me so that this information can be corrected.


Alright, Step 1 (instructions under image)
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/01.jpg
Select "Merge to HDR"

Step 2
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/02.jpg
Here's the window that will come up

Step 3
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/03.jpg
After you select your three or more images click okay and wait. (This takes a minute of so and the screen will flash with windows opening and closing)

Step 4
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/04.jpg
This window will come up when the process is finished. Notice the three images on the left, these are the ones that I took (one regular, one over, and one under). Here you set the Whitepoint like Daredevil had said on the histogram. Also for better compatability and further adjustments, set the Bit/Chanel down to 8

Step 5
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/05.jpg
Click okay and wait for the progress bar.

Step 6
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/06.jpg
This is the tonal mapping I was mentioned earlier. Here you can change the exposure if neccesary.

Step 7
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/07.jpg
On the drop down go to "local adjustment". Here you can change the radius and threshold and play with them how you like. I find setting them a little higher creates a surreal "glow" kind of effect. Your choice.

Step 8
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/08.jpg
Click okay and wait, the image is now being made.

Step 9
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/09.jpg
At this point you're basically done, but as you can see mine were done on the beach and they were still really washed and I also want to show one more thing....

Step 10
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/10.jpg
Under adjustments, select "equalize" This will level some of the high spots and make the image a little more "deeper" looking.

Step 11
http://i63.photobucket.com/albums/h130/CanTheWhales/HDR/11.jpg
Notice the sky is much blue-er? That's equalization. If your still not satisfied, you can go into image>adustments>... and and change hue, color balcane, contrast, whatever, but this is the best this picture will really ever be.

So there, I hope this helps, and I'm sorry they wern't a nice of pictures as Kirk's but they were all I had at the moment.

Also thanks to ShiZor9 for letting me shoot his 'Vert that day.

Again I hope this helps, if not let me know and I'll see if I can better explain it or fix any problems.

It seems to me like you're all missing the point of HDR. Lets start with a definition:

Dynamic range is the range of light that a camera can record in any specific scene, from light to dark. With your normal dSLR you'll get about 6 stops. To put it simply, think of it this way: your camera can only capture a certain range of light at a time. You can move that range up and down via exposure adjustment, but it won't grow or shrink. Anything OVER your range will be OVERexposed (recorded as a hex value of #FFFFFF). Anything UNDER your camera's range will be UNDERexposed (#000000).

HDR involves taking multiple exposures of the same scene at different exposure values. A typical example would be taking your base shot at the exposure value chosen by your camera's meter, taking one picture at +2EV and one picture at -2EV. In your first picture you have captured 6-stops of light, and you have captured an additional 2-stops of light in each of your other exposures (The second pic moved the range up two EV's, the third moved it down 2 EV's from the base exposure). Combining these pictures together should give you approximately 8 stops of light in your picture.

The purpose of this is not to create a surreal, oddly highlighted picture. You can use it to do that, obviously, and there's always going to be some portion of a surreal effect but that's not what it was originally intended for. The purpose is to capture detail in a scene that is not normally possible via your camera.

In this thread there are a bunch of images that have been run through the HDR process just for the sake of processing, and as a result they seem over-processed to me. Once you get over the novelty of HDR, it really doesn't serve a huge purpose for most scenes.

HDR is put to good use in scenes that have a high dynamic range. One example would be when you're taking pictures of a subject in a shadow with a portion of the scene including a sunlit background. Normally your camera will expose for the shadowed subject and blow out the background leaving you with a background that is either mostly or completely white. HDR would
bring the background back into the scene and provide some detail.

In closing, here's an example of a scene that benefits from HDR. This scene would have had too much dynamic range to capture without HDR.

P.S.: I'm not going to get into tone mapping or explaining why everything starts to get the halo effect. If you're interested in reading more on HDR, start with the wikipedia article: High dynamic range imaging - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/High_dynamic_range_imaging)

I need someone like you, to really teach me HDR.

Cause I can't figure it out, even following the directions people posted.

First off, ditch the Photoshop HDR tool. Get yourself a version of photomatix from wherever it is you got photoshop from.

Second, see here: Stuck In Customs » HDR Tutorial - Featuring HDR 2.0 (http://stuckincustoms.com/2006/06/06/548/)
This guy is amazing with HDR techniques. Knowing the theory is one thing, getting pictures like this is entirely another.

Nice Write up 94TurboGSR :thumbup:

Just something i noticed with this picture that may help some understand the "concept" of HDR, rather than "Ooo...it looks cool"

In a BIG scene, like this picture, its almost always hard to catch the full color and detail of the whole scene. By taking pics under several exposures and processing them in Photoshop, you can create a picture that will show details in both the dark and bright areas of the scene.



Example:

http://img63.imageshack.us/img63/2862/tablewithredboxdisplayog1.jpg (http://imageshack.us)

Box 1: There would be no way to see ALL the way back here...Without HDR Merging. Not to mention the color quality of this area.

Box 2: Dark clouds are a bitch to shoot when your not focusing on them. Again, Without the Merging process, you wouldn't be able to get the detail in the clouds to that extent. It would be more of a solid object and an area of darkness.

Box 3: Since the Fisher Price is obviously the point of focus. These areas wouldn't have much detail either, Due to it being overcast. But the HDR even brings out the ripples in the sand. Just another example on how bad ass HDR is.

So as 94TurboGSR said, knowing the theory is one thing, getting pictures like this is entirely another.

BUT...At least you have the theory down :D

nice post info guys..

i've been starting mine with photomatix and finishing up with a lil touching in photoshop..

it'd be alot easier for me to practice if i had a frikin camera...

*****TO ALL WHO HAVE A GOOD CAMERA******
feel free to post up some pics with different exposures for me play with :D :Thumbup:

Thankyouverymuch, sir.

I know the theory. I just don't really care for HDR most of the time. I find that I'd rather take the exposures and cut/copy/paste in photoshop without the help of an HDR processor. HDR pictures are generally plauged by halo's around any areas of large contrast, and that's easier to limit when I'm not working with an HDR processor.

Anyway, here's an HDR I processed with photomatix. It's good, but I prefer my original:

So I want to get a setting with a big dynamic range for it to work right, right? So at dusk, dawn or an overcast day would be ideal? I have a point and shoot camera that goes from -2 to +2 s I can get some variation on exposures. I'll give it some work this weekend if I like anything I'll post it up. You guys should get side jobs as photography/photoshop teachers.

Those who can, do. Those who can't, teach.

I probably should be a teacher. :-P
