Flickr member bengt-re serves up this dusty electronics eye candy of a 47Ω resistor in the wild. I sure enjoy me some good ciricuit board macro and this shot has some sweet detail including specs on it’s creation –
Camera: Canon EOS 40D

I’m curious what sort of macro lens was used and if there was much cropping.
For the screen resolution it’s easy for the Canon 40D to get a shot like this from 20 feet away. But if it’s uncropped, it is a much more impressive feat.
Not really all that impressive. Looks like he’s using a Sigma 70mm f2.8 EX DG macro lens, so this must be 1x magnification or less (unless he’s using extender tubes). My Canon MP-E 65mm could just about fill the frame with that crack on the right side if I cranked it all the way up to 5x magnification.. not that doing so would be any better of a picture, necessarily.

Photos are lovely, and without pics it didn’t happen, but really I’d quite like to see a line or two about what the resistor is -in-. It’s clearly attached to something and it’s been there for a while. This would be more interesting to me than a “this is a resistor” photo.
I know what a resistor is and I don’t think it can be that unusual knowledge for this site.
@Stephen – This is a pic submitted to our flickr pool and I enjoyed it – thought others might as well.
You can likely find more info by commenting on the flickr page.
If you like resistors, I have a photo on Flickr that shows some very old carbon composition resistors that are marked with the pink band that denotes “high stability”: http://www.flickr.com/photos/anachrocomputer/287693395/
