Has anyone here made HDR images?

I'm really impressed by this technique, and as my new camera has automatic bracketing (it can take three photographs of the same subject at different exposures) I thought I'd give it a go.

Any tips?

Ooh ooh ooh, cheers for that John I shoot all my phots on a three shot bracket, (can do it with 5 shots as well) so I'll be trying this new technique!!

[cyberhippie]

Wow nice effect, you can dowload free software here

[Hyderabadi]

I've been reading up about this technique too and am going to try it out.

Thanks CH for the link.

There is another program, not free, http://www.heliconsoft.com/ which I've downloaded for trial.

I have got a full version of Photomatix PRO V 2.3.3, with serial numbers etc.  

Please let me know if anyone wants it, and I will send you the link by PM.

I have uploaded it to a file sharing website.

Can you convert to a web friendly format with this Mecurie, I'm really taken with this and would like to add some stuff to my web pages!

Hi CH

I really dont know if you can convert to a web friendly format with this, but you might want to ask John or Hyderabadi, who seem to be familiar using this application.

The all I can do is to send you a full version software by email.  Let me know.

Merc.

those HDR  photos look great. Can regular images be HDRised using software, or is HDR a feature on cameras?

[Hyderabadi]

It should be possible to work with the image as a .jpg and save it to any other format. This particular program does not save to .gif. Only .tiff which creates huge files and couple of other HDR formats. But using say Photoshop you could save for web. I know CS2 supports HDR.

Here are a couple of tutorials I found:

You use regular images and run them through a piece of software...

Hyderabadi's links are worth checking out.

[Hyderabadi]

Thanks Mercurie for the software contribution (    ) and John for the topic. I did get to try out HDR Photography and below is the very first result...only do not ask me please about issues with MS Vista and its amazing problems with .crw files....that doesn't even belong on this forum.

There is another larger picture on flickr, for those who would like to look at it in full size.



Have time I think for another beer and another picture....

As I'm discovering, it is possible to shoot in  (not in the RAW ) .RAW ( if your camera has the option + it may be called .crw / .cr2 / .nef / .mrw.. and so on) then with a program that can read and edit such files, change your exposure settings after the picture is taken, save them with different file names and go HDR.


But that would be cheating of course.   

Here's another one:

You need to experiment with the settings on Photomatix to get interesting results, but it is very versatile and capable of producing dramatic effects or subtle ones!

I have not tried doing HDR with a .raw file yet, because I have simply bracketed three photos (-1, 0 and +1) and used those.  The results have been really interesting.

I have put together the graphic below to show the basics of HDR.

I can't wait to get out there with my tripod in good light and get some really good shots

I have a feeling we are just scratching the surface John. I remember reading somewhere about not just bracketing but a more 'pure' form would be to eaccurately expose as well as focus on three different elements of the same scene, say 'One Pen Please' boys, the Taj Mahal behind them and the dramatic clouds behind it and make a HDR image. Or was that even HDR? Worth trying though.

I'm not sure  where I read this but I'll try and dig it up.

[Hyderabadi]

And it may be too soon for me to say this being a - Two HDR Picture Wonder, but the technique seems to be more effective in landscape than macros, considering the light and shade?

Edited by Hyderabadi, 08 June 2007 - 01:23 PM.

[john.sw]

It works well for macros too!

It is fantastic for architectural shots, partly because the subject doesn't move!

Here's another handheld shot with a bit of jiggery-pokery.  I have to say that it is so much more fun than my old darkroom - there's no cleaning or washing up to do afterwards!

As far as using three different photos, I haven't tried it yet, but I shall!

Um... Save As...

In fact, PhotoMatix converts to .jpg .tif and .bmp automatically.

Some of your flickr photos, excellent as they are, would have been fantastic in HDR!

[cyberhippie]

I'm still on the free version which doesn't allow to save as Jpeg just Tiff or hdr

Anyways the whole thing just stopped working, I hate Vista

[Hyderabadi]

Here's another one.

BTW, some of these pictures were taken on and around Brasstown Bald, the highest point (4780ft) in the Georgia part of Appalachian mountains. . Went there on a small vacation and came back yesterday. The kids got to do a bit of cycling, trekking and fishing Rainbow Trout (which we grilled later).



These are Mountain Laurels.
