Thank you for asking, because I forgot to note a few details from earlier. Once you install it, while in the game, press Shift+F12 to enable the effect. It basically adds several different effects to the game such as bloom and blurring. I will post a few screenshots tomorrow as an example.
The guy who created it was boris vorontsov and it was designed for GTA San Andreas. It turns out that it worked in a bunch of other games (because its based in DirectX), so many communities have been distributing it in various places for each of their own games. Whether you have the right to upload it to the file library, I can't say for sure, my apologies.
I don't believe it's a problem based on how many other places are distributing it (but of course that's not always the best way to measure). It used to be distributed by RailSimDepot but they are closed down now.
Some people don't like the effect when enabled, but keep in mind that tweaking the "enbseries" file (it is easily editable as a text file with somewhat obvious variables) can change the strength of the effect.
Edit: I should also note that it's pretty GPU intensive, so depending on your graphics card, the framerate hit may be too much to use. Currently at my settings, this drops me from ~160FPS to ~60FPS.

There are definitely some moments when it seems like too much. However, I haven't confirmed yet but I believe that spec5sx's screenshots of his UP Cascades Sub route has HDR turned on it and I definitely think his screenshots look amazing. I could be wrong of course.
