HDR - Frustrated

rsparts

I'm having a very hard time getting this right. I use Auto Bracketing on my camera to get 3 different photos at 3 different exposures - usually -3, 0, +3. I then load them into Photomatix and press "Generate HDR Image" but all I ever get is a crappy looking, usually overexposed, image that looks nothing at all like what I want. So I try tone mapping only to end up with the same crappy effect even after playing with a bunch of the different sliders and whatnot. I always end up with a feeling of frustration that I can't shake. What am I doing wrong??? bagh! It can't be this hard. I have read and read but I just don't get it.

Would you mind posting some samples? Post your final result, even if you don't like it? Even better, could you give us the original RAW files to play with?

I'm not expert when it comes to HDR post proccessing, but I have taken a few damn good HDR pictures. This is my latest, and I don't know if there is a thread to post HDR pictures. I take atleast 5 pictures to get more tonal distinction. Let me know what you think of this Picture. Is this what you are trying to do?

(Side note: Shot for the 5 Speed Kings. Queens, NY.)

Photomatix is crap. I abandoned it about a year ago. I now use Dynamic Photo HDR for all my HDR rendering. It's much cheaper, more simple to use, and you have much more options when rendering.

Here's a few done using Dynamic Photo

Dynamic Photo looks really nice. I'll have to download a trial. Is it a stand alone app or a photohop add on?

I believe it's only stand-alone. For $55, it simply can't be beat.

Those are amazing pics by the way Kenny.

Thanks, these were shot over at the American Airpower Museum on Memorial Day weekend at dusk at -2, 0, +2 on a D100. PP was done using Dynamic Photo HDR, and used CS3 only to tone down any excessive noise.

Kenny,

I find overexposure in Photomatix can be controlled through the black and white point sliders somewhat. It depends on the look you are going for!!!!

The first question I would ask is are you getting the complete tonality of the image in your exposures? +3, 0, and -3 should get you pretty close in most instances, however, you may need more in some cases. Try shooting in manual mode and change exposure values via shutterspeed and see if you get the same result. Find the correct exposure and keep underexposing until you have very little light left in the scene and then do the same at the other end. The underexposed image should be ALMOST completely dark and the overexposed image should be ALMOST washed out. I also take more that 3 shots (usually about 5 or more).

I posted this on my blog about my experiences with HDR (http://willpridham.blogspot.com/2008/07/high-dynamic-range-rural-landscape.html). I usually do exposure blends on landscapes, but recently I've begun experimenting with HDR and all its wonders!!!

By the way, I think many of your photos look terrific! Some are a little on the unrealistic side, but that's ok too! I can appreciate digital art. I love your plane photos!

KennyS

I wish I could have stayed at each plane to take more exposures, but this was an invitational event I attended, and I was working around 20 other New York photographers (with a dying battery). My mindset was to have courtesy the whole time as there were many classic birds to be shot. If I had more time, I certainly would have taken more frames. As for the realism, I appreciate the comments! HDR is a touchy subject with a lot of shooters, and it's nice to see someone look past the process and appreciate the image!

Anyone know of any way to do this in Gimp?.... i.e., manually?

PS: Great work everyone!

EDIT: Never mind... search is your friend!

Kenny,

What I've learned long ago is this... I shouldn't really care what other shooters think with respect to techniques used. There are too many chefs in the kitchen nowadays...

Its the same as the fly fishing being the purist sport argument... It's narrow-minded. Quite frankly, if photographers want to shut the HDR method out of his/her toolshed that's their perogative. Not very smart in my opinion... but their perogative non-the-less.

Push the envelope so that your images are unique and different than other photographers. I know a wedding photog here who uses tonemapping in his WEDDING photos. The photographer is internationally known and gives lectures on shooting weddings... Sometimes his skies look a little unnatural, but that is what the client wants.

HDR is like portrait photography. Nowadays, the rules of portrait photography are very lax compared to 10 years ago (i.e. never show the back of a woman's hands, no split profiles, etc...). Why can't HDR break the rules too?

Great pics!

I use dynamic photo HDR and like others have said, is mostly about what you want to acomplish.... of course having a good tonal range between all the expositions helps a lot ( a picture that shows the darkest well and then ranging to one that show the lightest part well as well) shooting RAW also makes it way easier during the tonemaping.... here is my hdr gallery:

All these New York photographers that I've never met. :cry

Results look crappy without tone Mapping. I hope this will solve your problem

Yeah, really excellent, Kenny...
