optifade optimised?

17 03 2010

Okay, I guess I have to apologise for not having many photos from this year’s IWA. What can I say? When I wasn’t walking from one appointment to another, I was waiting to see people, and when I was free to take photos… well let’s just say I need some practice with my new phone to get half way decent pictures from it!

One thing I tried to get a record of was some of the new ‘forest’ coloured Optifade deer-hunting camo from Sitka. This is the first time I’d seen it in the flesh, and one or two hunting sports retailers had it on their stands.  You can judge for yourself in this photo, but to my mind the balance of that colour palette just looks wrong for sitting in a tree-stand.

Their original Optifade colourway was based on their “deer vision” theory, I’m wondering if this colouway is somehow based on that same principle.

According to the theory Optifade are using, which is based on the part of the electromagnetic spectrum ungulates can see, there should be no green on the pattern, so the green should be replaced by brown.

There should not be any blue either! The blue should be black. The colour ungulates like deer can see is green, so avoid any form of green.

My understanding of deer vision is that they are much more sensitive to blue light, marginally less sensitive to red, and that they cannot distinguish between red and green.
I’m not sure where there’s blue in the pattern, but I can definitely see wanting to remove that if it’s present.

“The colour ungulates like deer can see is green, so avoid any form of green.”
What? It doesn’t matter if an animal “sees” a color. What matters is if a color matches *their* perception of the colors in the terrain. That may mean using a different type of green, or it may mean getting away with a yellow or orange instead, but it’s not about avoiding the colors they can see. If camouflage was about “avoiding colors they can see,” we’d clothe our military personnel in flat-black UV-reflective jumpsuits.

S-sorry if I sounded like a douche earlier.

What really worries me – maybe you guys can put my mind at ease – is I can’t see this stuff disrupting symmetry at a distance. It just looks like a really nonspecific texture map. With what I understand of non-primate vision and processing, symmetry is what I’d most be worried about, and yet this stuff seems like it would just blob out into a human silhouette at 200m, probably quite a bit shorter for an animal with less-than-primate visual acuity.

I am only going by what Optifade e-mailed me, it shows that deer are most sensitive to yellowish green and bluish green. So only brown or greyish green, as I would think brown would look greyish green to a deer which can not see red, would be needed. If I were to go by the info from Optifade then on a winter camo, when most deer hunting is carried out, should have either no green or very little green, if that is what deer, which are leaf eating machines, can see. So I would say from the info from Optifade that any form of bright green would be attractive to a deer and attract its attention, and see the hunter, or am I wrong?
As far as humans go the most effective colours have low illuminosity (brightness) like Olive Drab, and Stonegrey-olive. Black is detectible because it has little reflectance at all and looks like a very large area of shade, sometimes black is indeed the most effective colour in some situations. If there was a colour only humans could see then that would be a bad colour to choose.

Oh, yes, definitely, though in that instance it’s as much a matter of matching the background as it is dealing with the deer’s spectral sensitivity.
I know value comes into play somewhat, but another major factor (and one I think you’ve touched on with the greens) is saturation.
Low-value or luminosity colors work well against a dim background, but in an area dominated by something like sand or snow or concrete, you want a commensurately light value.
Regarding deer, they’re not quite as sensitive to red light, so that might be considered a color only humans can see. Colors near red – brown, orange, etc. can work okay against both, so long as the color either matches something in the background or environment, or appears to match the background when spectral sensitivity or the effects of distance are figured in.
Oddly, bright orange works somewhat well against deer, as their lower spectral sensitivity turns it into a somewhat dull color that we might imagine as olive drab.

The pattern Dominic took photos of at the German show in March looks similar to the Optifade (U.S.) Big Game Forest pattern, but it is actually the new Optifade European Forest pattern. The U.S. Big Game Forest pattern is for Tree Stands (up in trees) whereas the European Forest pattern (shown in the photo) is meant for ground (stalking) hunting. There are differences in the directional flow of the two different Optifade Forest patterns (U.S. = Verticle flow vs. Euro = Horizontal flow) patterns and the coloration is different between the two.

Yes, I designed both of these patterns for W.L. Gore (Gore-Tex) with input from Dr. Jay Neitz, a top expert in ungulate vision, and my design partner; Lt. Col. Timothy R. O’Neill, Ph.D. (U.S. Army, Ret.) the world’s top camouflage expert. We have special algorithms, based on extensive R&D, to show us how the patterns appear in the ungulate vision. Specific colors used can be identified by the ungulate but in such a way as they only see specific portions of the pattern and actually causes the ungulate to see through the pattern as if nothing threatening was there.

Thanks for providing us with that clarification, Guy.
