Taking 3D Shooting To The Limit — with 3 Cameras!

Or n cameras for that matter: Taking 3D Shooting To The Limit — with 3 Cameras! – Creative COW.

I have been thinking about this same idea. At times, we don’t know what the inter axial lens spacing should be for 3D – so why just shoot with n cameras instead of 2?

Having 2 cameras gives us stereoscopic views. But sometimes we need different spacing – adding a 3rd or 4th or more cameras to the camera array enables us to record multiple stereoscopic views simultaneously.

Before long, as n goes to infinity, I guess we end up with holograms!

Consumer 3D TV market remains small

This refers to broadcast cable/satellite/over-the-air 3D TV viewing:

Only 2 percent of TVs in the U.S. are able to show 3D programming, according to the most recent data from research firm IHS Screen Digest. Thats about 6.9 million sets out of 331 million. After this years Christmas buying rush, IHS expects the number of 3D-capable televisions installed in homes to jump to 19.3 million, mostly because 3D viewing technology is being built into most new large-screen TVs. But even with the jump, 3D TVs will amount to less than 6 percent of all sets.

Which is also why I think 3D is taking off “online” first. “. Broadcast needs huge markets while online delivery can work for small market segments, just like the hundreds of small market Youtube channels are working today to deliver content to consumers and profits to small producers.

The future of 3D “TV” could bypass the traditional multi-channel delivery model.

A few more macro #3D images

Ran out in the yard late in the day to grab a few closeup photos. Being at a northerly latitude, its already fall and most things are drying up and dying off.

All photos taken using one Canon SX1 IS in macro or super macro mode and moving the camera between the left and right images.

Red/cyan glasses needed for viewing.

Macro Mondays? Time to ramp up close up 3D photography

Yesterday, on a whim, I shot some 3D close ups using my Canon SX1 IS macro wide angle lens feature. One of the examples I posted yesterday, and repeat again in this blog post.

It occurred to me that we do not, exactly, see good 3D with our binocular vision on extremely close up subjects. In fact, when looking at things really close, it may be easier to shut one eye and focus only with the one eye.

Our eyes are too far apart to see good 3D on very tiny objects at very close range. But a camera can take images just millimeters apart, creating beautiful 3D rendering.

Perhaps we should start a new online meme of “#3DMacroMondays” or similar! If you use Google+ and follow any photographers, you know what I mean – there are days for landscapes, portraits and what not.

I know that I am going to start shooting a lot more 3D close ups. Its easy to carry a single camera while hiking and there are plenty of miniature subjects to choose from!

If you do not have a macro capable lens, you could always pick up some inexpensive extension tubes. For example, here are some micro-four-thirds macro extension tubes – I plan to eventually get these for my m43 camera: Macro Extension Tube Set for Micro Four Thirds Cameras
