I noticed some noise creeping in on some images so I've put up a new version 1.85 which has a 'Quality Boost' option. It takes about 3x longer with it selected but the results are much cleaner so you can push it harder. Here is one of my Natural History Museum shots with the detail on Maximum and the Quality Boost on. Again, not necessarily to my taste but it shows how far you can push it now.

I tried a few freeware programs which just seemed to do some simple and unimpressive tone-mapping which wasn't the effect I wanted so I wrote my own program. I've put it here http://www.martinandanna.talktalk.net/autohdr.html if anyone would like to try it and feedback would be welcome. I've only been playing with it for a few days but I've found some ways to reduce halos in most pictures and keep sky and faces smooth in most situations. Got some more ideas but they'll be more work to program.

Very simple to use - you just open an image, process it automatically and save the result. There are a couple of options you can adjust but the defaults work well on most things I've tried. I think this is my favourite so far. I love the effect it gives on clouds and water.
Martin,

First of all, kudos to you for having to skill to WRITE a program of this nature! I've only had my camera for a couple weeks, and 1 of the first things I said was that I want to process pics to HDR. I am mesmerized by the quality of the pics after being processed this way.The program (of choice) seems to be Photomatix. I thought I was going to have to buy a copy of it, then kept reading and came across a post of someone that was using your FREE program. Among other things, I LOVE the fact that your program processes ONE pic! I thought I was going to have to start of by learning how to take pics under multiple exposures with my camera. Also, I love the simplicity of your program. Just load the pic, process and save. I love that there are a few adjustments you can make to tweak the outcome of the pic, but not so many that they are mind boggling. A simple, yet effective program that a BEGINNER can understand, and it's FREE! You can't beat that with a stick! I suppose that one day I may have to "graduate" to the use of Photomatix, but for right now, I support you and your program 100%! I'll be using it for at least a YEAR to get my HDR skills honed. Also, I'll post pics on here for constructive criticism.

I really like the results from the right side of the building up to the hannuka bush on the lower left. After that not so good. All the vegetation looks pretty bad, but the brickwork on that building and windows are awesome.

Thanks. I think this example shows the importance of starting with a good shot. There's just too little useful information in the trees to get a good result there in this case.

I agree with Bynx. The trees on the left look way over exposed, but the building? MAGNIFICENT detail. I'm still playing with the program with some of the images I took. I'm still trying to choose which settings work for which pics, but when I get it all looking right, I will post some before and after pics.

QUICK GUIDE TO USING PANASONIC RW2 FILES WITH AUTOHDR

1/ You need AutoHDR version 1.87 or later
2/ Open the file in SilkyPix and save it as a 16-bit tiff
3/ Rename the file extension from .tif to .tiff
4/ Drag/drop the .tiff into AutoHDR
5/ Process as normal

Here's a quick before/after taken with my new FZ38. The 'Before' is the jpeg created by the camera and the 'After' is the jpeg created by AutoHDR from the 16-bit tiff:

Before:


After:

My first try at this autoHDR. I have a Sony a550 and knew the contrast was extreme but I took it anyway. Some may not know the CN Tower in Toronto. I used DRV Level 1 I think. Thank you Martin as your program rescued an otherwise good memory but lousy pic. Do you have any opinion on the in-camera Dynamic Range options in the Sony (and I believe Nikon...)?
