Macro Monday: A Series of Electronics Macrophotographs #manufacturing #macro #photo

Macrophotography is the photography of small things.

That’s the loose (and somewhat prosaic) definition anyway. In truth, there is no agreed upon standard for what constitutes a ‘macro’ photo — it’s rather subjective; c.f. the first three paragraphs of the Wikipedia “Macrophotography” page for a litany of conflicting and overlapping definitions.

My definition of what qualifies as “macro” is technical, but pretty loose. I use magnification as the figure of merit. Anything from about 1/5th to about 10x magnification qualifies as macro for me. Less than 1/5th magnification I’d consider “close-up” (highly scientific term) and greater than 10x I’d consider microscopy.

Now that we’ve defined our terms, here are a few macrophotographs of electronic stuff. All of them were a blast to shoot. I hope you enjoy them.

  1. These are beautiful, John. We were taking macro shots of various types of 3D printing filament recently and could’ve used your expertise. Next time I will remember.

  2. In the past I’ve done some 35mm Macro Photography of my Model Railroad. I used a lens designed for the purpose, a 105mm Micro Nikor on a Nikon FE camera. Nikon makes a 52mm Micro Nikor as well, which is a bit more popular (it’s less expensive!), but the longer working distance wit the 105mm made the difference for me with model photography. For the kind of closeup work you’ve shown either lens would be fine. Depth of field goes to zero at these magnifications, the use of the lenses F32 setting is usually required, and some people have modified their lenses to go to F45 or smaller! This requires a high effective ASA rating or lots of flood lamps. I nearly melted the plastic on my models before I realized how much heat my photo floods pumped out! I had to use more lamps further away from the model!

    I now have a Panasonic G3 camera. The kit lens it came with can get close, but you have to manually focus. I also use a set of screw on closeup adaptors left over from my Nikon. Luckily the Panny lenses also take 52mm filters.

  3. Wow! Those are awesome. That last Neopixel one in particular stands out. I love how it’s even turned on while you’re shooting that one :)

  4. Super interesting routing on the GPS module. Wish I knew more. Great images and great work John. :)

  5. I have always been fascinated by photos of the internals of chips, PCB close ups, etc. great stuff.
