Flickr member bengt-re serves up this dusty electronics eye candy of a 47Î© 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
Exposure: 0.5 sec (1/2)
Focal Length: 70 mm
ISO Speed: 320
Exposure Bias: -1/3 EV
10 thoughts on “Aged resistor macro”
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/
