Well, when we project a bright video image onto a large movie screen in an auditorium, the image appears brighter and easier to view in detail when the lights around the screen are off. Turn the house lights on (in other words, light up the peripheral area) and viewing the image is not as enjoyable.QuoVadis:Well let's take a quick lesson in how you "SEE" something. Light bounces off an object, comes back at you, enters your eyes, your brain processes the info. If the light that comes back at you is blocked by a black skirt, you will not process that because it is not getting to your eyes. A clear skirt will let the light enter.
I compared masks on the net and this was one advantage that the clear skirt had....especially for photographers.
Simple really. Now are you a converted?
Also, I noticed that when you take an eye exam, they darken everything outside of what you are viewing.
Sorry, QuoVadis, I'm not converted to your POV.
