The discussion of boat color for best visibility reminded me of a pair of photos taken from a Canadian search aircraft that was posted on the Folbot Forum (http://www.folbot.com/yak.htm) a couple months ago. The first is just the bare bones; the second has the "survivor" located. The survivor is wearing a hi-vis yellow PFD, and I believe the aircraft is operating from their "standard" search altitude. The photos are taken on a bright, sunshiny day, with what looks like a fully-developed 15 knot sea running (white caps, in other words). The challenge is to see if you can locate the survivor in the first photo. Anyone thinking that hi-vis anycolor helps much to make you visible from a search aircraft should take this test. Can't post the jpegs here, but I'll email the pair to those who want to take the test. Or, maybe somebody has a Web site I can shoot these to? Happy searching. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Many have asked me to send the pictures of a "Survivor" clad in a hi-vis yellow PFD via email, and with the source's permission, Mark White has agreed to post the pictures. I wish I had more info on them, but my source did not have that.

David and Mark, thank you very much for those sobering jpegs. Gonna make sure I carry my smoke and dye anytime I'm on open water.....

G'Day, Thought provoking photo's! Our local coast guard who get deeply involved in helicopter rescues told me that reflective tape was often visible from a helicopter.

Reflective tape seems like a very inexpensive way to add a factor of visibility. I've read suggestions that people use these patches on the deck and hull. Placing strips on paddle blades helps, too. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Very impressive, makes you stop and think about everything you would want to have with you if you were in that situation.. I remember reading an article about the USCG using animals, and I can't remember which either bird or mammal, that had much better eyesight than humans, in helicopters to locate people in the water.

I didn't say anything after viewing them on my system at home but I confirmed what I saw when I looked at them on my system at work. The area in the vicinity of where the kayak is supposed to be looks a bit mottled to me. There seems to be a slight greenish tint on the photo only in the area around the location of the kayak. Looking at the photo with photoshop and zooming in to 400% and it looks like a "smudge" tool was used. Maybe it was just the lighting in the photo. I certainly hope a doctored photo was used to prove a point. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

> > Gonna make sure I carry my smoke and dye anytime I'm on > open water..... > Dye has been on my list for a year, but I haven't found any at local boating stores (Boaters World and West Marine). Someone on paddlewise mentioned over a year ago that "plumbers dye" worked well. Can someone elaborate on this - can you be more specific than plumbers dye, how do you carry it and in what quantity, what's the shelf life, etc?

My eye was instantly drawn to that spot, perhaps because of the surviver there or perhaps because of a bad doctering job. When I look at the blown up image I would say it is suspicious, but I can't conclusively say it was doctored. It just may be that the surviver is just a more diffuse reflector than the highlights on the water. In any case the picture makes the case very poorly. As I said before, there are a lot of reasons why this is so. The eye is an amazing receptor capable of resolving many times more detail than can be displayed in a 585 X 410 pixel jpeg. Furthermore the brain can process moving images to get far more infomation than one still image from the same data stream contains. Are dye and smoke packs a good idea? Absolutely. Does this picture drive that point home? Not in my opinion. Pete Staehling Yahoo!

I would not trust any JPEG photo to show fine details, simply because it is a "lossy" format. When a JPEG file is compressed, info is lost that cannot be recovered. Everytime the image is opened and saved, more info is lost. The higher the compression, the greater the loss. And high contrast edges often acquire halos or other artifacts during compression. It might be these artifacts you are seeing, rather than deliberate tampering. TIFF, TIFF, hooray!
