More Window Frost Abstracts

Here are a few more macro frost images. The first two, size-wise, are about 5mm on the long axis and the last two are about 2mm.

interesting abstracts Doug - I dig em'

wow these are pretty incredible. I really like the light refraction in the first shot . Out of interest, do you mind sharing what lens set up you used for these?

Thanks for the comments, Marko & Runmonty. I use a 3:1 macro lens I kluged together from some old prime lenses - a reversed 50mm Zuiko (Olympus) attached with masking tape to a 135mm f3.5 Takumar (Pentax) Screwmount telephoto. To mount it on the camera, I use a Canon T-ring adapter from my astronomy gear. The focal point is only a couple of inches from the lens and the depth-of-field incredibly small, even with the 50mm lens stopped down to f16 (The 135mm is always kept wide open). Therefore I've just recently added a new accessory to keep the lens parallel with the window pane - a tube which butts up against the window. The only light in the frost images is coming through the window glass and frost into the lens. The image field with the camera's sensor is 5x7mm and I crop images from these. Here are a few shots of the setup.

Individual lenses and tube.

Wow that is quite set up. Thank you for sharing Doug - you have achieved some super results. I just keep going back to look at them.

Some very cool images and quite the lens set up. :thumbup:

Thanks, Iguanasan. Here are two shots from another day. Very little sunlight was getting through the white cloud cover, resulting in more monotone images. I like it better when there is blue sky and the sunlight lights up the brown and grey colours on my balcony, and then those colours get refracted through the frost.

These are really interesting formations making really nifty images! Thanks for sharing!

Wow, these are tres cool, Doug. And the way you got there is amazing. Well done.

Amazing crystal formations captured here Doug. Very well done.
