The most exciting technology available in the present period to create 3d pictures is the use of CAD software. This technology allows the production of extremely smooth 3d images from any CAD drawing. It is this ability to create unique 3d pictures that has attracted the attention of large numbers of architects, interior designers and artists. The result of using this technology is that you can design anything from skyscrapers to cars and space shuttles with ease.
In order to create unique 3d pictures all you need to do is to adjust some of the design parameters of the model. For example, if you wish to have a building with an old-fashioned design, then you would be well advised to alter the aspect ratio of the model by increasing or decreasing the ratio of the height and width of the building. In order to give a building a unique look you can experiment with different values of x and y for the different ratios. You can also change the viewpoint by altering the perspective of the camera. All these things can be done with the help of sophisticated CAD software. The 3d pictures will be a reflection of your choice and the combination of the various aspects will give the final output.
Another very interesting type of 3d photography is stereo 3d photos. Here you have a simple choice of two views, one straight ahead and the other normally referred to as orthoscopic, which can be tilted through the use of a panoramic camera. This stereo effect is obtained through the fact that the images that are produced are of equal size on both the views. The advantage of stereo 3d pictures over normal 2d photos is that it gives a much more realistic and natural look to the photographs. Also, there is no loss of resolution since both the views are of the same resolution.
One other interesting type of 3d pictures is the depth of field effect, also known as the shallow depth of field effect or depth cue. This type of effect was discovered long back but has only recently started being used in modern 3d photography. With this effect the depth of field is formed by a blurred or blended image of the object placed in front of the camera. The camera then tries to match the blur on the near side of the scene with the depth of field on the far side. This produces a shallow depth of field effect.
This type of photography is also known as blurring of the field. Depth of field photography was first developed in the war field during the Second World War. The blurring was due to poor vision conditions and was later adapted in commercial photography when the processing speed was increased. The blurring in depth of field images can be observed in any good SLR photography program.
The usage of SLR cameras has increased tremendously and now all photographers require having at least one SLR camera for every photo shoot. Most beginners go for the automatic settings but later on move up to the manual mode. SLRs are very useful in capturing natural scenes. For example, taking a group photo of people at their workplace can be done with an automatic or a semi-automatic mode. However, in order to take crisp and clear 3d pictures with more professional results, you will need to use the aperture settings. The wider aperture will let more light to enter the scene and hence provide better color and contrast.
