Hey gang. I'm finally back, and here is out two part series on HDR. I'm starting this thread so we have a place to talk about HDR, and exchange question/ideas. I have spent the past month working with HDR, and I have to say it's the most exciting thing in photography I have ever found. The key is all about how you use it, and I'll be talking about that in more detail next week.

Here is a shot from the Rimrock area that I took in HDR last week... Gavin www.seimphotography.com

Gavin, this is a great shot. Try the technique on some of your portrait shots. Then use the channel mixer in photoshop to tranform to B&W. You will be blown away.

Also if you like what the Tone Mapping steps does to the images, check out LucisArt @ www.lucisart.com/. There is a trial version. This is a extremely interesting plug-in that will bend your brain.

Have fun!

Regards,

MikeV.

Just to add to this, the image below was done with 3 RAW exposures and pushed through Photomatix/Tone Mapping. It was then brought into Photoshop for the B&W work (channel mixer, dodge & burn):

Here is one of the better ones from my first crack at HDR. I took this handheld while waiting for my Sr session to begin. I added some grain and glow in PS.

I am finding that I get really gross over saturation on most images even after tone mapping. Is this just a matter of messing with the different sliders and settings in Photomatix?

Do most of you shoot 3 shots for HDRs or 5?

Thanks!

3 or 5? It depends on the contrast of the scene. I've found that if 3 images cover the entire contrast range, throwing in a few extras that overlap really does nothing but muddy the water.

Without a tripod I use the my Auto-bracketing on the D70s which "at best" can do 0, +/-2 stops. On the tripod I use up to 5 exposures - but this is a huge "pain" on windy days.

Texas Blue Bonnets
Hdr with 3 exposures at +/-2. There was a little bit of movment in the bluebonnets but i blended it out.

HDR is quite lovely, however, often overdone in my estimation. To me an effect that overwhelms the subject is distracting from the value of the original image...in my mind. This one of the bluebells is quite a good balance, I guess I have to keep playing around to get it right.

The setting that keeps HDR from looking "fake"... (in Photomatix) is the light smoothing slider. I tend to keep it at 1 or 2. anything lower and you get a halo.

GRRegis says:

Dreamer2471985 is right about the light smoothing slider, but I also find that the strength and color saturation can also make the Image look "fake." If I'm making a realistic HDR, I like the keep the strength and color saturation around 40-50 and the light smoothing cranked up to 2. I've been experimenting off and on with HDR for about 6 months and still hardly an expert at it, but here are a couple of my favorites. I'm posting one that is more realistic and one that is more "fake" because I think that some element of "fakeness" can be good. Also, another application for HDR that I haven't heared mentioned is night shots, and in my opinion it really gives them a pop that is hard to achieve otherwise so the realistic one is one of the night HDRs I have done.

The Square

Fountain at Wangfujing HDR 1

I also have an HDR set that has all the HDRs I have done over the past months. Looking back on some of them now (OK a lot of them), they are really over done, but I feel like I should keep them up to show how my technique has progressed or changed. www.flickr.com/photos/grregis/sets/72157600186405763/

Agree with GGRegis. My earlier HDRs look quite different than what I produce today. Also during that time Photomatix has evolved too :-)

Here's a shot from this past weekend.

I listened to the first HDR edisode on the show yesterday (I'm a bit behind on the episodes). Anyway, just wanted to show a HDR I did a few days ago.

There are some situations where I like HDR. This is one. It was impossible to get a good exposure of both the window and the other parts of the image so i did a multiple exposure and merged them in Photomatix. I still want it to look natural even if it's a HDR wich i think this does.

I also like the other pictures shown in this thread. HDR pictures that still look natural are great!

Jas15duke2, thanks for the comment, I really appreciate it. I too think that was one of the nicest one I've done which is why I posted it evnthough it's not very realistic.

I like the way the lines on the brick flow Roger, and I know what you mean about windows. I feel that this show needs a solid object of interest

Hey Gavin,

I know this post was started a year ago but I was just out to Utah and Page Arizona and got to swing by the Rimrocks.

I use DPHDR (mainly because it is inexpensive, easy to use and produces good results). The keys, as someone mentioned above, is to keep the over-saturated look to a minimum and produce realistic photos. I have an HDR set on flickr and I've gotten a chance to do HDR in buildings and outside. Here is a link to a couple of the shots:

Bryce HDR

All are from different environments but I find that 3 shots, -2,0,+2 seem to work very well. I have found that my Manfrotto 486RC2 does better than my 322RC2 head to prevent slight movement when combining the photos.
