AV369 operates Route 121 on the 20th October 2009. This image is shown here in stereo. It can be viewed in 3D with Anachrome red (left eye) and cyan (right eye) filters.
If evolution has decided that stereo vision is fundamental to the appreciation of depth in every day life, then why should bus enthusiasm be left in the dark ages with a 2D depth-less representation of the bus world. This photo above shows what I believe to be the first 3D (3-Dimensional) image of a Dublin Bus, AV369 on O'Connell Bridge operating Route 121 to Drimnagh Road on the 20th October 2009.
This image was taken on a dark, dreary, wet Dublin day, signified by the umbrellas that people are carrying. The bus is in motion and is not a perfect shot in the modern image stabilisation, high ISO bus world. However, such complications to the scene further ad to the 3D effect and the sense of depth within the scene.
Just like any stereo image, it needs two perspectives of the scene. In this case the camera is equipped with two lenses that simultaneously take photographs. Then from interpreting the scene, knowing the width between the two lenses, the scene can be seen in 3D in just the same way as the human brain does with its two 2D images.
For the moment, I have gone for one of the oldest techniques for viewing which only requires Anachrome red (left eye) and cyan (right eye) filters, so if you have an old pair of glasses with one red lens and one cyan lens then this should work. The basis for effect this is that the eye is sensitive to three primary colours, Red, Green and Blue. By overlaying two images, associating one with Red and the other with Cyan (the mixture of Blue and Green), one can use the red filter to filter out the cyan image seeing the scene from one perspective, and the cyan to pick out the image from the other perspective. Hence you get a different persepctive in each eye, and hence you see depth.
This technique is a very simple one and the image itself doesn't look good on its own. Much work has gone into the development of 3D techniques, however before the widespread deployment of 3D monitors we must live with some of the more basic techniques.
The two different images are shown below. For the moment its best we stay in our image stabilisation 2D world, however one day 3D may be the norm for bus photography. Let it be known it was done here first. Appologies for the boring explanation, lesson ended.
The left and right images respectively that combine to give the stereo image above. Seeing the differences between the scenes is difficult, the easiest things to see are at the boundaries, where for example in the right image you can see more of the advertisement panel on the VG and more of the taxi plate, while in the left image you can see more of the harp in the flag on the right.
