Started over in my Glock thread I thought I'd start a new thread for sight comparison.
Not a professional photographer and I'm just working with lighting in my basement, so this is kinda of crude, but maybe it'll help those who've never seen FO or Trijicon sights.
First to recap: Standard white outline-dot sights in regular room lighting.
Now let's dim the lights an move all of them forward of the gun. In a tactical situation, I don't want to be back lit anyway. So this would be a more critical, home defense lighting scenario. It's also what you run into on some indoor ranges with poor lighting at the shooting position. The target appears brighter than it actually is because exposure was based on the back of the gun. (Told you I'm not a professional.)
Next are examples of Fiber Optic and Tritium sights side by side with regular room lighting. Note the Tritium's aren't very "white" and don't show very well in light.
Now let's dim the lights some. Again the target is over exposed because of the long exposure time to show the sights. The Tritium's are starting to strut their stuff, though the FO's haven't lost it totally yet.
Finally, let's really get some low light levels. You can't see the front sight because my focus was on the rear and the camera was looking between the two guns. Not the perfect sight picture. Imagine your bedroom, 2am in the morning, something's moving just outside your door way. Only the nightlight and some street lights coming in the window are what you have for illumination. That's why I like my Trijicon's for my house gun.
As crude these pictures are I hope they give a feeling for the difference between the various sights.
Of course if you have a 2,000GigaJigaWatt LED flashlight mounted on your gun, you can just blind the intruder without firing a shot.
