Its free and IMO the best addon out there. Here's the site http://enbdev.com/index_en.html . Its fully configurable and after many hours i think i have found a nice sweet-spot on the setup of night vs day. Here are the installation files http://www.mediafire.com/?jq0ouyd0mnj . Just drop both of these into the main FSX directory and it will work.
d3d9.dll : modified d3d file.
enbseries.ini : configuration file (my options included).
Shift + F12: turn whole effect on or off.
Shift + F9: turn bloom on or off.
Shift + F10: turn occlusion on or off, off by default (don't use this, very heavy on fps, marginal benefit in 3D cockpit if u look closely at edges)
Shift + F7 & F8 & F11: turn on reflection, shadow and water effect, all off by default (they don't seem to have any affect o FSX for me, this mod was originally for GTA)
There are also motion blur and depth of field effects but all they did was blur my picture so off by default. Some of the other stuff may work but I haven't figured out how to get them going. Here is the ini file for viewing. The key headings are [BLOOM] and [COLORCORRECTION]. I will post some pictures shortly.
NOTE: Many have problems getting it working with the correct drivers. I'm using Nvidia 9800GTX with latest 195.62 WHQL driver. 185.XX and 186.XX didn't work for me. The general feel I was going for was realism. Darkened cockpits when facing the sun or a bright sky. Eyes adjusting as you look away from the light into the cockpit. The night is like a black hole. No more night-vision goggles or seeing the horizon in the dark with 5 mile visibility. Try a manual ILS approach with 1/4 mile vis. You really need those instruments!
