Can anyone tell me what this is? They are all over the glass and about 1-2mm across.

Hi!

I have no clue what it is, but it looks cool...and ominous.

The image is an extreme closeup. They look white to the eye. I didn't even know there was any color till I blew this up.

Those appear to be sessile jellyfish, I think they are very cool.

That's a really nice photo, you should post it in this thread!

Here's something else I found on the glass. They are about 0.5mm to about 1.5mm. This one is about 1.5mm.

sailmike...I am trying to take some pictures of my own and it seems that you have the closeups down to an art. Any comments on your camera settings. I have an Olympus Z-50 zoom camera with 5 mega pixels and I can't seem to get the closeups to come out as good. Any help would be appreciated.

Actually my dad took it. He is the expert. We used a Nikon D100 SLR camera mounted on a tripod with a 105mm macro lens and three extension tubes to magnify the object. Then tried different F-stops to find the one that worked best. After that, the picture was cropped in Photoshop and also the color improved. It is very important to use a tripod otherwise the picture will be blurry. We used a shutter extension to trip the shutter so as not to shake the camera. This was our first time trying this kind of a picture.

There should be some threads on how to take photos somewhere on this site.

Hope I helped some,
Mike

rubiconman: Check out the photography forum. However, its not just megapixels that make a good zoom camera. You also need a high "optical" zoom to "digital" zoom ratio. The higher optical zooms will give you very nice close ups, but the high digital one's will not. Reason being- the optical zoom magnifies through the lens, while the digital zoom magnifies the image after it is taken through the computer on the camera. My father in law was all impressed with the new Canon he had bought, plus telling me several times about how he saved 300$ compared to the Nikon I had bought. Then he took a close up of some roses. He couldn't figure out why his 5mp camera's images were all pixely and grainy and my 5mp camera's were not. Until I showed him the reason for the cost difference, his camera was 12x zoom, as was mine, yet his was 3xoptical, 4xdigital. Mine is 8xoptical, 4xdigital. I have the nikon coolpix 8700. Canon does make good zoom cameras as well, this wasn't one of them.
