Yet another new (well, June paper) lens design using metamaterials to create high resolution, planar optics.
Said to work across the visible spectrum, due to use of a material that neither absorbs...

Very nice tribute, Steve!

Great image, Joe! That little camera really works well.
Is that structure really just a stack of containers? Where are walkways, etc.?

This paper reports on a new method of creating flat, diffractive lens structures, an evolution beyond Zone Plates.
Apparently, by creating transparent photoresist patterns of varying thickness (on a...

I tried for quite a while yesterday evening. I never could get past the CAPTCHA!

Count me in, please!

Brilliant, Ned!

Very nice, Ricardo! Amsterbridges - I see two, at least...

Great image! Too bad it's not in color, though; that looks like a lovely specimen of A. muscaria.
Not really all that toxic, unlike its cousins. A bit "magic", and at one time, highly prized by...

A couple of beautiful shots here, Ned! And the Shell Beach Tide Pool brings back so many memories of hanging out and exploring there, and all of the Sonoma Coast, as a kid!
Maybe this summer, I can...

WOW! Makes me think of a landscape on Titan!

We haven't decided where to go; cloud cover is obviously very important.
The Northwest segment looks good, but for a (slightly) longer period...

Thanks, Ned! We're so close to this one, it has to happen. even if I end up in a wheelchair and have to roll myself up north!

There's a lot of "legacy" equipment out there, but I'm not familiar with much of the medium format gear I might find on eBay, etc.
I'd like to find (cheaply, of course!) a motorized 6x6 or 6x7 cm...

Look on amateur telescope making sites for mirror cleaning ides.
Yeah, the projection lenses and filters are intriguing! Extreme aspherical lenses, for which I haven't thought of a good use.
The...

The one I pulled a couple years ago was glass! On the order of 1.5 x 2 feet, maybe bigger.
Cat knocked it over in the living room shortly afterwards, though!

Look for a discarded rear-projection TV. They have a very large first surface mirror at the rear of the cabinet.

Not my work, but I just ran across an interesting set of images.
Finnish photographer Marja Pirila's project, "Interior/Exterior" combines people and their rooms with projected exterior images.

To which I have to point out that the entire 1966+ Adam West Batman series will be released on Blu-Ray in early November.
~$175 on Amazon, but as it's the one and only Real Batman...

All quite lovely, Nick!
The second with the mushrooms and skull(?!) is a very striking grouping, but if my attempt at identification is correct, the previous occupant of the skull died from...
