Learning to “see in 3D” to improve 2D photos

As a 3D stereographer, I am always aware of the 3D space in front of me. And when shooting 2D, I often wish I was shooting 3D!

The key idea, in this linked column, is that by learning to see in 3D, we can improve our 2D photos. You might think “seeing in 3D” is obvious – after all we see a 3D world around us. But truly, as 3D photographers know, learning to see in 3D is a technique all unto itself.

How to create 4K 3D Videos for Youtube

Using Sony Vegas Pro (and presumably newer version of Sony Movie Studio)

  • I used the MainConcept AVC/AAC (*.mp4, *.avc) codec
  • I selected Custom Frame size and set width to 3840 and height to 1080.
  • I set maximum bps to 40,000,000
  • I set average bps to 32,000,000
  • On the Project tab, I set Stereoscopic 3D mode to “Side by side (full)”
  • Upload the file to Youtube
  • Add the following as individual “tags” in the Youtube “tags” section:
    yt3d:enable=true
    yt3d:enable=LR
    yt3d:aspect=15.99:9
    yt:crop=16:9

After Youtube recodes the video, the viewer will include 1440 HD and 2160 4K viewing options. Select your 3D viewing options and select 2160 4K – note, you need a fast Internet connection. This produces a much higher quality 3D image than the normal Youtube 3D configuration.

————-

Using Magix Movie Edit Pro (version 13 – should work on 14 too)

  • Compress the output to an mp4 video as 3840×2160 (not 1080). This creates a vertically stretched “half frame” on the left and right – however, since its 1920 wide, we end up retaining all of the original 1920×1080 on each stream.
  • Set to side by side, half frame (didn’t work for me when I set to full frame side by side)
  • Select a high bit rate such as 40 Mbps or faster
  • Upload to Youtube with the tag yt3d:aspect=15.99:9
  • In Advanced settings, select “This video is already 3D, and then select “Side by side: Left video on left side”.

After encoding, this shows up as a 4k 2160 3D video and plays as you would expect, but at a much higher image quality.

Gondoliers inside The Venetian, in #3D red/cyan anaglyph

As you know, everything in Las Vegas is a little out there. Inside the enormous Venetian hotel and casino there is a canal and gondoliers shuttle visitors along the interior canal, while singing.

This was taken with a Fujifilm W3, handheld, at probably 1/30th or 1/15th second (I didn’t check the EXIF) and ISO 800. The Fujifilm W3 becomes quite grainy at ISO 800 but it was needed in this poorly lit area.

#CES2013 #CES Report on consumer 3D cameras

Consumer 3D cameras are not selling.

The Lumix 3D1 is still being sold but I picked up word that sales are slow and it might not be continued, perhaps later in 2013.

Fujifilm is no longer manufacturing the Fujifilm W3 (confirmed) but is continuing to sell from existing inventory. I was told by a Fujifilm staff member who knows the issues well, that sales have dropped off sharply on the W3 – if demand were to ramp up, they can immediately run another production run. However, reading between the lines, its not ramping up – to illustrate, B&H Photo and Walmart.com both listed the camera as discontinued. At least from their sales. But if two huge vendors discontinue selling the product, then sales volumes will not be ramping up.

Toshiba has no cameras on display at the show and no one had any information on the Toshiba Z100, which is pretty much half priced at Amazon and B&H right now.

The Sony Bloggie 3D is no longer being made, but they are showing the new Sony TD30 which updates the TD10 which updated the TD10 video cameras. These uniquely record two full 1920×1080 video streams, producing very high quality 3D video images. Sony is also showing their digital recording binoculars, which view and record in 3D. They were also showing a prototype of a new model that is smaller and lighter and which will be available this coming year – no info on time or price.

The big announcement though, is Samsung’s NX300 and the new integrated 2D/3D lens. The 3D images I saw looked very good. Here’s a view of the camera with the dual 2D/3D lens in place:

The camera can output a live 3D video over HDMI, and they were using that to show live pictures of convention goers. The Samsung reps I talked to felt that the other 3D cameras on the market were too low end (my thoughts too). The early adopters for 3D are not low end consumers, but the semi-serious amateurs who buy $500 to $2000 cameras and look for quality.

The NX300 is an APS-C sensor, a very high quality camera system, and the world’s first single lens 3D camera. The parallax is quite good based on what I could see (both naked eyes and using active shutter glasses on their monitor). Here is what the parallax looks like – click on the image for a bit bigger version (due to being on a cellphone link, I’m using smaller picture sizes than usual):

I am very impressed with the NX300 3D image quality. If a wider angle lens version of this became available, I could see using this as a primary 3D still and video camera.

GoPro is the other vendor that continues to have a 3D solution. They have a package that combines two GoPro Hero cameras and a sync cable between them, plus some 3D alignment capabilities in their Cineform Studio (free and pro versions).

Consequently, a mixed bag on 3D consumer cameras – sales are confirmed as not being great at the low end.

But Samsung might have figured it out, though. The 2D/3D lens is a darned good 2D lens and will likely be bought just for that. If sales are decent, Samsung will introduce more lenses featuring the 3D capability.

Everyone is showing 3D TVs, including 4K 3D TVs (I don’t know where you’ll get 4k content for a while yet – there will be a new Bluray spec for 4k but its not done yet.) I really liked the Samsung Ultra 3D TV (4K) – wonderful image quality. It seems that the extra resolution enables some very fine parallax to be used – something to think about. Such fine detail would be lost in lower resolution renderings.

3D is being shown, but its not all over hype at this point. It’s just 3D. Stream TV, an R&D firm from Europe was showing the best, hands down, glasses free 3D display. They also have a tablet glasses free 3D display.

The technology pieces are coming together. I don’t think the marketing has been where it needs to be yet, on consumer 3D image capture.

I cross posted parts of this to two 3D related photo groups on Yahoo.

Other items of interest

LG had the world’s largest 3D video wall. Their sample video made outstanding use of “theater space” projecting images 20 feet or more in front of the screen and at times, nearly over the viewer.

The Winbot is a great idea – it is a window cleaning robot. I think the price quote was $299.95. Considering the bother of cleaning windows, this is an amazingly well targeted product. Cleans an entire window like this in a few minutes.P1000784

 

 

This year’s new thing is giant smart phones – how big is too big? I have no idea. But 5 inches and I think even 6 inches are being shown in places.P1000795

 

 

Sony has a lot of software accessories now. Some, not all yet, are beginning to understand how software can add value and differentiate their products from competitors. Another example would be Nokia, who is adding a large number of software-based features, available only to owners of Lumia phones.P1000773
