As far as I am aware (I too no longer post in the new Photography group, 14 years was long enough!)
Peter lives with his parents and has written some great scripts. As he didn't partake in the group for very long, maybe he 'gave' it to Rusty? I wouldn't know.
As far as I am aware, Rusty doesn't write scripts, but does take good photographs :-)

Enjoy trying PSP 2019, I have stuck with X9 for the time being.

JoeB wrote:Back in the days of PSPX1, a member named Peter Anderson (aka Rusty) created a script called Rusty's New Dynamic Range script, the stated purpose of which is to increase the dynamic range of an image. The practical purpose is to even out the dynamic range of an image where, like the image originally posted in this thread, the lighting is uneven in a gradual way, although of course it does affect the dynamic range overall. The major perceptual effect is to make the darker areas lighter and the lighter areas darker, and it affects the entire image.

I applied the script to this image. But because it made the sky much more dramatic (like applying an HDR filter) I first I isolated the sky area by selecting it, promoting it to a layer, then going back to the previous layer and running the script. Also, the adjustment layer it creates defaults to an opacity of 50%, and I hiked it right up to about 93% until I felt the lighting was fairly even.

The first image is the result of just using the script.

The second image - personal preference - is the result of taking the image created with the script then Clarity at 53 and then Brightness at 11 and Contrast at 6. In other words, if the script does most of what you want to achieve, then other tweaking - brightness, contrast, colors, sharpening, etc. - can obviously be used to suit personal preference. Of course you have to merge the adjustment layer created by the script before you can do further tweaking.

I have used the script many times over the years on images with this type of lighting problem. If anyone thinks it would be useful just let me know and I'll post it in the Scripting sub-group.
Hello JoeB,
I am interest in using the script you mentioned. Can you post it ? Thanks
