Fake High Dynamic Range (HDR) Script

Post#1 by tim » 17 Mar 2018, 21:09


found here: http://registry.gimp.org/node/11776
hdr-eff.zip #
zipped .scm file (unzip, put in your GIMP's /scripts/ folder) Changed code to add a copy of your original layer below the top layer so that you have a copy to play with (requested by Pat)
(2.19 KiB) Downloaded 595 times
The result is very saturated in colors.
I use it the result from this script and turn down opacity to use as a color boost layer.

Interesting T, I am especially pleased with the outcome of the sea and shore, however the sky and clouds are a bit rubbish.

RJKD, if you don't like the sky you can always blend (since this image is easy to blend).
So that you keep the sky of original but have the land of the resulted image.

Here I tried to blend it with darker sky.

Tin, I think you found a nice script. I like the effect. The only thing I don't like is that when it runs, it incorporates all the layers you have in the stack so that you do not have an original copy available. Any way to fix that?

I tried this on a portrait of a woman. On lowest value, was too strong. I placed the HDR over the Original and adjusted opacity. I like the image. Does not look washed out as the original was a little.

The amount of color looks stronger to me once I uploaded it. There is still lots of room to decrease the opacity more to one's individuals taste.

yeah the script kills all your layers. I just duplicate image before running script and then paste the result over top of my copy.

UPDATE: @Pat625, I have added a changed version of the hdr-eff.scm (zipped) which will automatically create a copy of original layer and put it below the result so that you can play with original.

Tin, you are so sweet! I had duplicated the original but it included it in the script, or did you mean you did a copy command before you ran the script, and then pasted? This is so handy to have the orig at the bottom of the stack.

On these next ones, I put the HDR over the orig. and played with opacities, gave a better outcome. I think I can use this script a lot! Thanks for finding it, and for making it more convenient.

The script in first post makes a copy of your selected layer and then after the script runs and it calls flatten image, i then add the copy back in below the top layer so that you have your original to work with.
If you have the script in 1st post then you don't have to worry about the manual duplicated which i used to do which is:
I duplicated the image. then run the script on one copy, then after it's done I copy the result and paste it over my other original copy of image that script hasn't ran on.

sorry for being so dense T, what do you mean "blend", would i just use the original sky over the Fake HDR?
