A circular polarizer would have the same effect, they serve the same purpose as a linear polarizer for incoming light but depolarize the light passed to the camera. Its possible that a filter could have been used but I think it would have affected the reflection from the ball also plus the cloud reflections also seen on the water. I've seen some pretty clear water but this doesn't look right. Also, while the shadow of the boat is visible no detail of the bottom is visible. I don't know what the sea bottom is like in this area, perhaps its just flat sand with no rocks or things growing there.On Thursday, May 31, 2007, at 12:10AM, "Richard Knoppow" <dickburk@xxxxxxxxxxxxx> wrote:----- Original Message ----- From: "Jeffrey Thorns" <puresilver@xxxxxxxxx>I'd agree that the lack of a reflection looks odd, though this could be the effect of a linear polarizing filter, which will block out a reflection from a dielectric such as water completely for some angles. I'm not sure that this is true for the circular polarizers recommended for most modern cameras. Other than that I've seen water this clean is some mountain lakes where the water was so clear you could get vertigo while swimming.To: <pure-silver@xxxxxxxxxxxxx> Sent: Wednesday, May 30, 2007 6:57 PM Subject: [pure-silver] Odd pictureThis is not exactly a high-brow site, overall, but this one picture is a bit odd. Almost looks like it's been Photoshop'd; http://www.boredstop.com/index.php?option=com_content&task=view&id=15&Itemid=33Maybe its real but notice the ball or float to the leftof the boat: it has a reflection, the boat does not. Even ifthe boat is sitting high on a V bottom which is paintedblack one would expect to see some reflection from its whitesides. Also, although the image is not large enough to besure, there appears to my eye to be some odd blurring in thewater around the left side of the boat. Again, it _may_ belegit but (as Red Skelton used to say) somehow it just don'tlook right to me. --- Richard KnoppowAll the best LarryLos Angeles, CA, USA dickburk@xxxxxxxxxxxxx
