We’ve shared a few pretty cool cross-section light painting projects before, but none of them were ever very… shall we say… cheery. Both projects — 21:31 and Andy Leach’s hologram photo — were created using the same eerie video of human slices from the Visible Human Project. But for those who wanted to toy around with cross-section light painting and re-creating 3D light objects in their photos, that’s all they had.
Well, not anymore. Photographer Hugo Baptista has put together a Vimeo group called “Cross Section Objects for Light Painting“. It contains a number of videos that you can load onto your tablet or smartphone and use to create 3D light painting objects.
Lytro‘s groundbreaking light field camera is finally landing in the hands of customers, and to give people a better idea of how the camera works, the New York Times has published an interesting diagram that shows what makes the camera tick. Here’s what DPreview has to say about the camera:
The Lytro LFC is so unlike any conventional camera that it doesn’t make sense to score it in comparison to them. Ultimately, though, we’re not convinced that the Lytro either solves any existing problem or presents any compelling raison d’etre of its own. If it were higher resolution or allowed greater separation or could produce single lens 3D video it might generate a lot more excitement. As it is, it feels like a product arriving before the underlying technology is really ready.
All of which is a great shame, because Lytro has done a great job of making a credible consumer product out of a piece of fairly abstract scientific research. It’s quite possible that in the hands of the right people it will result in some interesting creations but we just don’t yet see it as a mass-market device.
The New York Times came to the same conclusion — that the technology is revolutionary, but the product isn’t game-changing… yet.
A Review of the Lytro Camera (via Photojojo)
Here’s a cross section view of the consumer light field camera unveiled by Lytro yesterday. Many people have been wondering about the camera’s output resolution. The official specs are enigmatic in this regard, as the resolution isn’t listed in megapixels (it boasts “11 Megarays”). If the diagram is to scale, however, we can learn a little about the sensor’s size. The camera is listed as being 41mm tall, so the sensor appears to be between 7.5×7.5mm and 10.5×10.5mm — roughly the size of a Fujifilm X10 sensor.
Update: Photographer Jim Goldstein did his own calculations can guesses that the photos are equivalent to 1-2 megapixels.
Leica and Sony aren’t the only camera companies that slice their cameras and lenses down the middle to give the world a peek at their guts — Canon does it too. On the first floor of one of its headquarter buildings in Japan is a small museum that has a cross-sectioned Canon 1Ds DSLR and 400mm f/4 DO IS USM lens on display. Back in the day, the camera had a price of $5,500 and the lens cost $8,900, meaning Canon sliced nearly $15,000 of gear in half for this display.
Camera innards are often shown in cross section diagrams, but here’s a Sony Alpha camera and lens that were actually sliced cleanly down the middle (we’re guessing a lightsaber was involved). The build quality of the lens definitely looks cheaper than the sliced Leica lenses we shared last week (as it should). Brownie points if you can identify both the camera model and the lens.

If colleges offered camera equipment anatomy classes, this Leica lens cutaway might be one of the things you’d be examining in the lab. It’s a Leica Tri-Elmar-M 28-35-50mm sliced cleanly down the middle, revealing all the glass and pieces inside that go into making the lens.
