Washing Camo

No arguing that but...

I’m talking about the entire visible light spectrum (near-ultraviolet and near-infrared).

After reading GTO's responses I'm talking about both. I find it interesting that his accessories showed up bright white and his cloths were somewhat hidden. I can't make sense of that from a straight IR perspective so I’m assuming these game cameras are more of a cheap night vision device and not an IR imaging camera (I have ZERO experience with game cams). If this is true it supports the following theory:

Some detergents have phosphorescent properties which enhance the ability to see when viewed with night vision devices.


It would make running both tests (cheap night vision cam and black light) with your no scent detergent of choice a must…from a research perspective.

If it's not true, then I'm lost!

This subject caught my attention because I am always curious if I’m glowing like a candle out there.

I think whitebeard said it best:

I just want people to know that there isn’t one detergent (key word here) that kills UV brighteners. Not a one. And if there is a detergent (key word here is detergent) out there that does, I’d like to try it out.


There are two aspects that can’t be argued: 1) If an IR game cam is lighting certain parts of your hunting gear up, you might have an issue and 2) If the Spearmint Rhino is lighting your hunting gear up, you might have an issue.

Opposite ends of the visible spectrum? Yes. Both visible to predators? Who knows, but millions of $$$$ are spent researching it.

Again, this didn’t help one bit but it interests me...AND you guys are making me think here.

Just saying, but I wouldn't get too wrapped around the axle about how stuff looks with night vision or nightshot or an IR game camera. At least not with regard to detergent or anything else you can do to clothing.

There are some dyes that are completely transparent to IR light. You can have some articles that have a camo pattern printed on them that look totally different seen under IR light. Some materials reflect lots of IR and look really light-colored when viewed with IR illumination. Some things that are really brightly-colored under visible light don't reflect IR well and look dark or muddy under IR.
Even some anodizing on aluminum is transparent to IR. Ever watched a hunting show featuring night hunting and noticed how sometimes the host's black scope looks "silver" with the night shot/NV on?

This is near infrared, just outside of visible for us. Image intensifiers (night vision) and chip cameras, like the game cam in question or a video camera, can all see IR. All chip cameras are inherently sensitive to the near IR spectrum; it's just filtered out for your digital camera or video camera. In that sense, the game cam is a cheap form of night vision.
Further out in the spectrum gets into actual heat. You have to have the real high dollar gear, passive infrared, to see that.
 
Game cameras are DIGITAL camera and use a "sensor" like a DSLR camera.

Some of these digital sensors are more sensitive to IR light waves than others.

Human eyes are not at all sensitive to IR Light waves in the IR wave lenght sectrum of energy.

Not sure what a coyote sees as far as the wave lenghts of light or other forms of energy like IR or UV light.

But I have read that dogs are color blind and only see in shades of gray.

So even if your IR senstiive photo cells in your digital trail camers detect IR light coming off your hunting cloths they coyotes may not see that at all.

The question here should be not can the camera see the bright clothing but can the yotes see it. Can you see it with the naked eye?

Another thing to remember is that the Trail Camera have IR beams of light that they shoot out to take pictures of animals with. But even with the IR light source we can't see that type of light in the dark. So can the animals see that light source? Probably not. That's why they went with the IR lights vs regular light bulbs. I'm thinking that the IR camera lights are sending out IR light waves only and not light waves in the visible spectrum. But I could be wrong about this. Anyone else have any knowledge of what the animals can see as far as the light waves spectrum is concerned?

I assume we are talking about what can be seen a night and what can be seen during the daylight as well here.

To take IR pictures with your DSLR camera put a IR filter on the lens and set your camera up on a tripod and use Live view and long exposures with regular ISO settings. Since the IR filter will block out more visible light the image view finder will be black unless there is a IR Light source shining into the lens. Since all the light in the visible light spectrum is blocked by the IR filter only the IR light waves are coming into the sensor. And remember that the Hot Mirrow is trying to block out the longer IR wave lengths. Some DSLR Camera hot mirrors block out more or less IR light so your DSLR camera may be able to take IR pictures. Or not. It depends on the type of sensor in the camera and the quality of the hot mirror IR filter.

I only wash mine every few weeks. If a coyote is downwind, you are busted in my opinion no matter what. I have been killing them this year with just a green wool shirt on or Saturday I had taken my camo wool sweater off and was just wearing a black carhart long sleeve t-shirt. I was sitting away from the caller 50 yrds most of the time. I'm getting old and have tried all that stuff they market long enough to think it is just there to make money, not help me kill coyotes much.
