The russian modder Boris Vorontsov is working on his ENB Series Mod for many years. This is developed for different engines in order to give engines for games(primarily good old games) a better optic transferation.
Boris uses often new effects he inplement into games with his ENB stuff or he adds a mod for renderpath increasing up a notch, for example DirectX8 to DirectX9. To the new used effects count various blurfilter and SSAO (Screen Space Ambient Occlusion) and Indirect Lightning - both techniques, that offer a better lighting and shading. Theres's reflexions and watereffects, too.
HDR stands for High Dynamic Range and offers an even more realistic way to have graphical effects for Lighting and Shading in games. One of the first major titles was Half-Life 2 back in the day that addressed HDR support in a patch. Since then almost any title has worked with those stuff.
Tim from ISI is probably not on boat with other graphic departments if he questions those namings which are fundamental nowadays.
Shows that ISI isn't the forerunner regarding graphics as said before. Anyway aquiring some of those techniques for rF2 shows are increasing a lot in their development.
