I've been playing with HDR software over the last few days.

I found this on the web.

http://www.essentialhdr.com/Download.aspx

The free version works very quickly,but only saves as a small file.
The full version is half the price of Photomatix but probably does not have as many controls.

Worth a try.

I tried this when I was first thinking about HDR but for me it didn't give the results I wanted. Might be user error on my part, though!

Have been playing around with Dynamic Photo HDR. Seems simple enough to use.

Anybody else tried it?

Have you tried Picturenaut? It's freeware and can be found at www.hdrlabs.com/picturenaut

Picturenaut includes image alignment functions as well as a tone-mapper. It doesn't accept RAW image input, so you need to convert the input images into 16bit TIFFs (without messing about with any settings in your RAW converter). The Picturenaut HDR output can be saved in a wide variety of file formats.

My first impressions are that this s/w is very fast and useful for producing a more natural style of HDR than many of the examples of exaggerated tones which seem commonplace from Photomatix.

The HDRI handbook mentioned on this site is an interesting read with some pointers on how technologies & formats becoming commonplace in the motion picture industry may influence the future of digital still cameras.

Thanks for posting that link - looks interesting and I'll give it a try.

Just to defend Photomatix - it doesn't have to produce exagerated results (though they can be quite startling and fun to do). A gentle hand can get quite a natural feel.

I posted this to the gallery a couple of days ago not intending to put it in a thread

Exposure-Blend - a plug-in for The GIMP is also quite neutral in its presentation, and as it presents the result as 3 layers very malleable (but limited to 3 exposures).

I've been trying to find the download for "exposure blend", but all the linked sites seem to point to a text download only.

Have you any idea where I can get it, for Vista?

Have you tried here:-

http://tir.astro.utoledo.edu/jdsmith/exposure_blend.php

then just copy the scm into your GIMP Plug-in directory - should be platform independant as exposure blend is a gimp script rather than a program.

(sometimes the site seems to vanish for a few hours)

That's the site I've been trying to download it from, I just get a page of script, nothing actually "downloads"

I've tried this link, in the section "Installation"
For Gimp v2.3 or later, use this version.

It goes to this page http://tir.astro.utoledo.edu/jdsmith/exposure-blend-tinyscheme.scm

These are the first few lines
;; exposure-blend.scm: Blend 3 bracketed exposures.

I haven't got a clue what I'm meant to do with it :o

Download the file, save it and then stick it here

Gimp2.6\share\gimp\2.0\scripts\

assuming gimp2.6 and a default install - should be on your c:drive under program files

Gimp will read the file and know what to do - it is all very undramatic

You will then find exposure blend as an option under

Filters/photo/exposureblend in the GIMP image window.

Hope this helps

I gotta backup Photomatix here, although alot of my tonemapped shots using photomatix are "pushed and extreme" photomatix can and does some nice tonemapping, I think its just easier to overcook things in Photomatix due to is easy user interface.

This is one of my more nicer shots using photomatix. Excuss the composition and compression :o

Nice example

I agree there is nothing intrinsically wrong with Photomatix and it can produce quite natural results.

The 'problem' (if you care to regard it as such) is that it has spawned a school of heavy handed users who go "WoW" and don't bother with anything much more than the top few sliders, the result is the typical Photomatix image, clouds and all.

Unfortunately that can end up producing images that have lots of detail, but very little real dynamic range - because it has all been compressed to make everything visible.

Even on your 'extreme' examples you obviously take care to avoid that pit fall and have produced some good images as a result.

Thanks Nick, but I'm still stuck.

Am about to reply to your PM :)
