I was interested to see this article. The big rush on this was some 20 years ago...
From what reading I've done since, yep, a lot of the "dyes" used to print up camo colors are high UV reflective. Deer have tons of "rods" and few cones in their eyes..ergo, better night vision and more attuned to the UV spectrum than color.
I've seen guys question all that "research" based on not being able to ask the deer...
I do trust that you can identify rods/cones in the eye by physical exam hence the "knowledge" on how varied critters see...
Ever notice how a flour org or green safety vest truly "glows" just at twilight? I figure it's something like that... the UV filtered shots I've seen show a rather glowing "whitish" when there is untreated UV...
Will deer always see it? Doubt it, if you don't move and they don't look at or toward you. I fidgit.
So I tend to buy the silly Atsko spray..soak the cothes I buy if they don't say "NO UV Dyes" in production of this product (which many have in years past) and then never wash with brightening agents.
I use such products year round at home... No dye/No perfume. It's a package deal and I opt for it to avoid perfumes..danged allergies!
So it's way not new... I even had some "filters" we used in Photog to check for "balance". By using them toward low light, I could see some of the "glow" in products... I bought a cheap ole "Black Light" bulb, put in a trouble light and hung my stuff in the garage many, many years ago and turned it on... Any of you (besides George)
old enough to remember going to a dance with a black light and your white socks glowed flourescent!? Or the lint on your dark pants? :eek:
I saw with the blacklight bulb where my clothes "glowed" and spraying the atsko uv killer...let it dry... went away.
What the heck... why not? it's all part of the fun of preparation... required? Doubt it!
Wool's fun...but sometimes too hot... had camo help me blend in and have deer look right through me many times as long as I didn't make eye contact... so I just have fun checking this stuff out and do what feels right...
