True, but define "useful" and you will find that some images are posted here as a bit of whimsey, some are posted as an example of a particular event or experiment the poster was involved in or shot. Occasionally an image has been posted to demonstrate a particular technique,

Pardon me for changing the subject, but here's an experiment. I spent some time doing some table-top photography a couple of days ago using radical edge lighting with a couple of lights behind the subject. It's harder than you might think because positioning the lights is what makes it work or not work. I was using just a couple of Home Depot clip-on lights and regular 60W bulbs.

I am not really into table top. But I think that image is rather interesting. Keep trying the effects using that method is neat.

I did about 150 shots using various items as the subject. The idea is to illuminate something that is clear glass in such a way that the edges are white and the inside is black in the way the unicorn is illuminated.

The unicorn is the only shot that is even close to keeping. The taller the object the more difficult it is to illuminate the entire edge of the subject. The unicorn is about 2.5" tall, so it was fairly easy.

I used a jerry-built softbox to diffuse the light, but my Home Depot reflectors and regular light bulbs don't focus the light well enough.

I got the idea from a fellow member of one of my camera clubs. Here's his:

That's two exposures, though. One for the radical rim light and one for the lemons.
