Re: Any recom for HDR (6x2EV) and batch proc?

It's getting better all the ti-i-ime. Magnified like this it is easy to see the warts, but it is so much better than earlier attempts! https://drive.google.com/file/d/1YJrdTuTYetaVff8czTJYLIuAdtyIB3c7/view?usp=sharing If that link does not show here, it can be viewed here: https://sites.google.com/s...

Re: Any recom for HDR (6x2EV) and batch proc?

Well all right! I have now gone through a full pass from start to finish, and the second attempt is posted here: https://sites.google.com/site/alistargazing/home/image-processing/crescent-moon-hdr . It's shown at 200% or 300% of full size so the warts are in one's face. The big unexpected thing is t...

Re: Any recom for HDR (6x2EV) and batch proc?

<r>And there was much rejoicing (ref to MP & Holy Grail).<br/> I still have a slog to reach the final answer but I figure I now have enough knowledge to get there. <br/> I was on the verge of asking for more help, when I realized that I still had a floating point image. After a quick search on f...

Re: Minor webpage documentation clarification for HDRI

Seeing no more comments and having received a request on github to complete the doc edits, I have done so, included snibgo's suggested mod. For the time being, consider this thread ended.

Some progress, some odd results. https://sites.google.com/site/alistargazing/home/image-processing/crescent-moon-hdr .

Re: Any recom for HDR (6x2EV) and batch proc?

Got it! I decided to keep playing with the notion of working in "high float" without dividing by 65536, so instead I chose the white threshold to be 15270 x 65536 -> 1000734720. I used 15270 since my previous guess at true saturation was 15284. Then snibgo's saturated count gave me: MIN=1.30025e+08 ...

Re: Any recom for HDR (6x2EV) and batch proc?

[edit: Succeeded in the next post - I will leave this "intermediate" post here for continuity] Even more progress! Thanks for your patience to my slowness... I found a ubuntu manpage for dcraw 9.27 ( http://manpages.ubuntu.com/manpages/bionic/man1/dcraw.1.html ), and I think I am starting to catch o...

Re: Minor webpage documentation clarification for HDRI

For the install from windows source ( https://magick.imagemagick.org/script/install-source.php#windows ), I recommend the following changes, all in the spirit of encouraging the non-expert to not give up too soon (I almost did). 1) Directly under the section header "Install from Windows Source" I th...

Re: Minor webpage documentation clarification for HDRI

I managed to create a pull for the first page before seeing your comment. This first one (shown below) is just a one-line change, and I will post the others here tomorrow before creating pulls. The others are of similar "clarification" nature. Very minor in the scheme of things but would have saved ...

Re: Any recom for HDR (6x2EV) and batch proc?

Hmmm, a bit puzzled... saturated sensels output gives me MIN=1.30025e+08 MAX=1.03037e+09 SAT_PC=100 which in a way makes sense since at 14-bit (Canon CR2) I am asking for pixels brighter than 16383. But min 1.30025e+08 ! Wonder if it has anything to do with the dcraw call? dcraw -v -D -W -w -g 1 1 -...

Minor webpage documentation clarification for HDRI

Hi, I have some simple suggestions for the HDRI and Windows build pages - is this the right place to post them? Some things are obvious to experts, but not being one, I stumbled a bit. Perhaps I could help in a small way?
Regards,
Alister.

Re: Any recom for HDR (6x2EV) and batch proc?

Ah, relative to the path containing the images. My relative newness shows - I had only ever used IM from one place acting on images in another. Until now I've never had to "attach" profiles to particular images. Thanks!

Re: Any recom for HDR (6x2EV) and batch proc?

Coming along nicely! Thanks to all your help and snippets snibgo, things are running without errors and I've gone from CR2 to XYZ space and down to sRGB. The XnView decode from CR2 left a bunch of artefacts along the blown-out line that the decode to XYZ to sRGB did not! ( https://sites.google.com/s...
