Roger Cicala reveals winners of First Annual Photogeek contest

By dpreview staff on Dec 2, 2013 at 14:32 GMT

Roger Cicala of LensRentals has revealed the winners of his 'First Annual Photogeek Geek Photo Contest'. What was originally intended as a light-hearted joke ended up receiving over 400 entries from at least 20 countries, and the impressive quality of the entries caused a real headache for the judges.

After a lot of deliberation, Rishi Sanyal won 'Best in Show' for his remarkable 'MacroSetUp' series. Using a whole array of accessories between his Sony NEX 6 and Canon MP-E 65mm f/2.5 1-5x Macro lens, he took pixel-peeping to extremes by imaging sub-pixel structures in the Retina display of his MacBook Pro, which he estimated as just 4μm in width (i.e. less than 0.2 thousands of an inch). 

Rishi Sanyal's winning entry included this image of his MacBook Pro's Retina display. The original image shows clear sub-structures within each individual pixel.  
Rishi's macro setup included bellows, extension tubes and a teleconverter between his NEX-6 and Canon 65mm f/2.8 Macro lens

Aside from this impressive effort, the winners covered the full spectrum of photographic subjects, from cats to cathedrals via teapots(!). Click the links below to read Roger's full roundup (which is entertaining as ever), and to browse through the full gallery of uber-geeky entries.

Never heard of that "Gaussian bokeh" before. The next weekend project it seems.

How about . . .

28:1 with a single (Nikkor) lens and no TC?

(Direct imaging of diffraction rings.)

I think the setup wouldn't be geeky enough, and you didn't shoot an iPad ;) A proper microscope objective would've been outright boring.

You could probably sharpen & remove diffraction rings by deconvolution?

That's very cool Marianne!

I was actually able to get >30:1 (160nm/pixel on my NEX-6) with a variation of my setup that used a reversed Sony 10-18mm f/4 at 10mm. It was hard to judge how much over 30x I got b/c the smallest reference I have is 0.8mm, and it runs off the frame slightly when aligned horizontally with the sensor (24mm sensor width/0.8mm = 30x).

However, I'm still waiting on parts to hold that particular setup together, stabilize, & light it properly. Hence I didn't manage to get any usable photos out of it, and haven't yet verified that it out-resolves the 14x setup I submitted.

Neat though that you can get so much mag simply by reversing a short focal length lens. Just tried my 10-18mm with my bellows/tubes & got ~20x.

It was interesting that even at 14x, sub-pixel structures of the shorter wavelength blue pixels resolved better than those of the green ones, despite Bayer sensors having half the blue resolution. Would be fun to measure blue vs. green/red Airy disks.

As mentioned in the text above, it's not just the color sub-pixels that were imaged. That's easy. Rather, sub-pixel structures estimated to be less than 4µm in size within each individual color sub-pixel of the Retina display were resolved.

Is that necessary? I can get similar results with one macro lens...I'm calling this bogus. Try it yourself with a single macro lens.

Is it necessary? No. Is it considerably more magnification than your single macro lens? Probably yes. The lens combination achieved an approximate 14:1 magnification.

You can see the sub pixels of an ipad with a drop of water:

Shot handheld with the 100L macro but you will see the colours (and even subpixels as the spot dries) with your eye.

The “Gaussian Approximation” by Shea Hadstrom looks very interesting.

If we would ever get a decent programmable camera API, it'd be interesting to see what else can be achieved by changing the aperture during exposure. (Just imaging toying with the zoom effect!)

Yeah, too bad, most cameras are not programmable today.
I have had same idea, I wrote about it here:
http://jtra.cz/stuff/essays/bokeh/index.html
but none of my cameras and lenses allow to do that (without freelensing).

jtra - you should read about Minolta Dynax 7. It got an "STF" function which bascially made multiple exposure shot with different apertures to achieve buttery-smooth bokeh.
No, it's not pure gaussian blur (gaussian goes to infinity, which is impossible to achieve in real world) but it's as close as you can possibly get to it other than a real STF lens.
