HDR Photography

Hey guys,
I was just wondering how i would go about creating HDR photos. I assume there is post-processing involved. So...what programs do i need, and what do i need and what do i do.

Thanks, Izak

Search on these forums for help, its been covered to death now.

Photomatix Pro in combination with Photoshop will do the trick

But indeed, there's a lot to be found on the forums (or the internet for that matter)

A very good HDR site is http://www.hdrphotos.n​et/

I had the same thought when I read the post because I was aware of that TOS. However, I didn't make the post because I didn't want to get in a poop squabble with another user. However, that being said I'm glad you had the nerve. POTN has changed over the last few months and I am seeing a sharp increase of the "google it" posts as well as serious questions being answered with smart**s replies. Either Pekka has decided to loosen the forums a little, or the moderators simply have too much to do. I would guess it's the later. /Dan

Nothing worse than doing a google search for a problem you have been having and it turning up a forum that finally after 2 hours of looking you see a post by someone asking the same question or having the exact same problem as you. Then when you look in the thread the only response is 'try google'. ARGH!!!!

Having said that I don't think the response was that bad. It might have been more helpful to provide a link as well, but didn't really strike me as particularly rude or anything.

I don't think it was rude, but perhaps you misinterpreted Radtech's post. It was not his language to use the word "jerk." It originated with the owner/originator of this forum who specifically requested in his stated rules that "search it yourself" replies not be given. Click on the link Radtech supplied and scroll down to #4. /Dan

Thank you all for your responses. I was not at all offended by sandos remark. I have been on these forums for a few months and have seen numerous threads on HDR. The day I wanted to delve into the subject that is HDR i couldnt find a single thread on it, spent over a half hour looking. Thus, i started this thread. Thanks alot for all your help and sorry for all the trouble. ANd thanks rzych for all the links.


Peace, Izak

Glad you wernt offended, I often think that seraching for an answer will provide you with a good grounding for doing your own research as opposed to just being given the knowledge on a plate. Anyway, im friendly enough... that's why i put a smiley.

I agree with Sando. Posts with smilies at the end can't be offensive.

My HDR attempts have been very frustrating so I was hoping to see some quality answers to this post.

I purchased Photomatix Pro,
put Canon 30D, Tamron 28-75 F2.8 XR Di lens on Bogen 458G tripod and locked it down.
used mirror lockup and self timer, manual focus
took 5 images from -2,-1,0,+1,+2, in manual mode by changing shutter speed only
generated HDR,
Used tone mapping to make the best image I could.

Results: YUCK!

Results appear to have washed out areas in all highlights, images not sharp, colors not saturated, etc.

HELP!!!!

Thanks

Would be hard to tell without seeing a post of the picture. Off hand, images only one stop apart may not be the best thing to do. Also, how much dynamic range was in the scene to begin with? If what was there could be really covered with one exposure, then you may tend to get a flat result. Take a look at http://hdrphotos.net/f​or tutorials on using Photomatix. This guy does better at explaining Photomatix than the people that make the software.

Does anyone know of a digital camera that automatically adjusts the ISO per pixel? I know Canon has amplifiers for each pixel so I think they could do it. I'm looking for getting the HDR function automatically when the camera takes one picture. It's just like in audio when you use a compressor to keep from clipping the signal. As the input approaches the maximum value it changes the amplifier to ease the saturation. It sure seems like this is the next step digital needs to address. Everyone wants to take HDR which requires several different exposures, and a tripod, to get the final result.

I searched Google to see what I could find, but didn't see anything.

Bill,

Currently, the only way to create an HDR is to take the 2 or more differeing exposures and blend them by hand, or using HDR software.
