Okay, let's get some CONTEXT and clarification here.
When I first addressed the camo issue with Doug (in the "cover scent LIE" thread), the CONTEXT was STILL HUNTING. You know, where you're not frickin' hiding up in a tree all day long. SOMETIMES, you get caught out in the open, with no cover. Deer appear when they appear, and sometimes you get caught off guard and you have to stand dead still, hoping the deer don't see you for what you are. It was then I supposed it would be better to be in a camo pattern like ASAT or Predator (patterns where the sole purpose is to break up your outline) than in a solid color. It was also there that I dismissed camo that turns into a solid blob from a distance (e.g. RealTree and Mossy Oak, etc). My argument has NEVER been that you shouldn't try to blend in with your surroundings (when possible).
When I made the direct statement to Doug that, assuming you were caught in this position during a stalk, "I guarantee you that if you are standing against a tree in a single solid color and I'm standing against a tree in ASAT, the deer will make you out first," he basically dodged it. And, it's funny, he posts an article here that's basically a backing for Predator camo or patterns like it.
Let's clear it up. Doug IS saying that camo makes absolutely no difference for deer. He IS saying that deer CANNOT distinguish between a jacket of solid color or a jacket with a pattern on it...that there is NO difference. NEITHER of the articles he posted support this, and NEITHER does a deer's limited ability to see color.
What I am saying is not that we can't have an UNDERSTANDING of how we THINK deer see, but that there is no way for us to KNOW EXACTLY how deer see. There is NO conclusive evidence whatsoever that wearing a pattern like ASAT does NOT help you blend in with your surroundings. There are, however, plenty of distant pictures that show exactly how well it DOES help conceal your outline and blend it into your surroundings.
UPHunter - Understanding engines and being able to observe how viruses work are not exactly the same thing as knowing exactly what an actual image looks like to a species with whom you cannot communicate. Even in talking to my color blind friend, it is very difficult for him to explain to me how he sees things, and vice versa. I don't think he can really comprehend what a human's full color spectrum looks like, and I can't understand what it's like to see in his more limited spectrum. It's kinda like trying to understand why a catfish likes to eat that nasty chicken liver dough bait. I can take a bite if I want to, but there's no way in hell I'm ever gonna "get it", even if a scientist could "explain" it all day long.
