on further testing drop down to medium dynamic range and you have no issues wth normal; hard or very hard

i agree with simple. After more testing, i like the mdr the best with normal.

i also find that the LOW DYNAMIC RANGE makes the image darker and in places you loose detial LDR should make all the detials visable and a tad lighter here is a example.

original


autohdr LDR normal settings


LDR with standard settings different program.


as you can see in the second image there is too much black being enhanced causing a lot of detial to be lossed from the bushes / trees directly to the building itself i have lossed way too much detial at the back of the building is almost a ocean of darkness no matter which of the 5 presets i use they all result in similar loss

i think you are on to a good thing here and i know your program is at early stages and i do thank you for letting me test it so please keep up the good work (m glad it works on 64bit)

Thanks Simple. I think I'm using the term LDR incorrectly so should change it to something else. I've got some interesting progress on automatically avoiding halos but still a lot to do. If nothing else it's a very interesting programming problem.

What is the other program you used by the way? I notice it is cropped more - is that your choice or something the program enforces?

Quick preview of the current and new version (under development) which calculates a much more sophisticated map to use in the adjustments. I'm also quite liking the new map on it's own - sort of a blueprint effect.

Having tried my hand at writing very basic code I can just barely begin to understand the amount of work that went into it. I am very impressed! I like the tractor picture a lot. It is not as "real" as some of the other hdr images on here but enjoy the effect immensely. Time to start hunting through the archives!

the detail enhancement looks better on the new one, be interested to try this one out when you get it finished.

this must have been a ton of work, impressive.

Been away for a few days but there is now a new version available at the same link http://www.martinandanna.talktalk.net/docs/AutoHDR.exe

It's a bit slow on larger pictures but I'm pretty pleased with the results so far. It's got a very smart fuzzy edge-detection algorithm I designed which means there are no halos. There are a few rough edges to smooth out but for now, here is Simple's test image on the 'Hard' setting:
