Nice Andy, Camera obscura?

Some glass fragments about 2-3mm in size, with the flash behind it.

Thanks, drizzle, here is the original if you like to add it to your wallpaper collection, or maybe make a big print of it.

Notice that I cropped the lower right corner and then mirrored it vertically to get the composition I liked the best.

Good guess, but no... I'll give you partial credit, tho :). No post-processing, either.

Ha! I don't have the kit, but that's the method. Longer focal length lenses use larger patterns- the photos above, using my 85mm, require patterns about 1" across (the front element is about 3" diameter), while my 24mm needs patterns smaller than 1/3"- too small for me to fabricate- I just print a design on paper and cut it out with a knife (under a microscope).

I tested a new optical device today, the crystal sphere.



This picture is intended as example in a photo challenge I'm going to host in DPReview next month. The title is "Still life: Raw and Product" and here we see quartz stones of which crystal spheres are made.

Ohhhhhhh I see there is quartz in my future....well coversands are quartz too.

So is that a quartz crystal ball or a glass one?

Should be crystal, at least the shop that sells them tells that These spheres are made by first crushing natural quartz in to fine pieces, then it's melted, removing most of the impurities. then it's poured into molds and finished / polished etc in traditional crystal ball methods.

But I had no chance to check it.

A great article today about photographing/filming food commercials:

I'm very excited here. I just got my brand new Pentax K-5 in the mail today and oh boy do I like it. Still learning how to use it but I absolutely love the build quality and low light performance. Below is a picture taken with the 18-55mm kit lens in a very poorly lit room (F4.0, ISO3200, F/25 i think). The image resizing really doesn't do the pic justice.

I don't go for 'camera pr0n', but I'll make an exception for this:



A colleague in the art department (www.markslankard.com) graciously lent me one of his view cameras to work with. We are doing a 'lecture exchange' next semester, he's going to talk to my Physics II class about photography and I'm going to talk to his Photo II class about imaging. The view camera gives complete control over the location and orientation of the plane of best focus, and I asked to borrow it because I'm having trouble getting a clean shot of this:



It's a vinyl record that is lit with grazing incidence- when the angles are just right, those colors pop out. For some reason, the area ion the left (closest to the lamp) is always fuzzy- it doesn't matter what I do. I'm hoping some time with the view camera will give me a better sense of how to control the plane of focus.

That's really excellent! Did you use any filters/polarizers to get the sky so dark?

Andre's dragonfly reminded me of a picture I took in Spring, during some training exercise over Zalew Zegrzyński.
