How does a three-dimensional display work?

Built-in screen works in a similar way as already known in the nineteenth centuryfotoplastykony. Each eye receives slightly shifted image that the brain is connected to athree-dimensional object. The problem was, however, the separation of the two versions of a photo or video. Applied to the sets of lenses, or two-color or polarized glasses. All solutions have the same drawback: the use of additional equipment required for viewingthree-dimensional images.

The three-dimensional camera for photography presented by Fujifilm is not necessary.The display is designed so that if you look in front of him, the two eyes may be routeddifferently image. The same works for digital photo frame, you can buy the kit. There is also provided to enjoy the 3D image viewing photos at the right angle and fixeddistance.

3d photography

Three-dimensional movies are doing a stunning career. Cameras to enable them tospin, however, are expensive. On the market there are cameras, while performing three-dimensional photographs. At the moment only available for the average model isKowalski Fujifilm FinePix Real 3D, but if the experiment succeeds, it certainly will goafter them other manufacturers.

Principle shooting is simple and has been known since 160 years. It mimics the way weperceive the world. The 3D camera has two lenses, which carry pictures at slightlydifferent angles. Just as the human eye. An image of each lens is cast in a separatematrix. Then both images are processed by the camera and stored on a memory card.Shooting is done so as in a normal digital camera, as long as you have become accustomed to a very natural way of holding the camera in such a way that does notobscure any of the lenses.

The same could have been done before, but this involved the performance of the twoimages into a series of carefully mounting angles and a computer. Execution of twoimages at the same time also allows you to capture moving objects.

There is more good news: for viewing images you do not need special glasses, at leastnot always. Can be seen on the screen of the camera or stand-alone display, on a typical monitor (with glasses), and soon even on ... printed prints!

Not about photography, but interesting news:)

Board of Directors of ICANN, which is the institution responsible for the granting ofdomain names, voted on Friday for running a domain. xxx, a long-awaited end, whichwould be characteristic of the pornographic. The decision was taken by a majority of 9: 3, and 4 Council members abstained. The turnaround in policy by ICANN may be so controversial that the first time the Councilhas acted contrary to the recommendation of the Governmental Advisory Committee(GAC), which issues opinions on draft decisions. Contrary to appearances, theadoption of the new domain is not telling the whole of the sex industry - some have already invested a lot of sites on this subject in the previously existing domains

Some tricks

Lighting plan was not too complicated, but it is not simple. Due to the need for a shorttime I did not flash the full freedom of power regulation. In which case it can be done? I will not say anything new, if you mention that the amount of light is mostly dependent onthe distance that must be overcome. Usually the larger the distance, it is weaker. Of course, sometimes the reverse is also focused beam, but the lighting of this type at thissession not been using, so for now I'll put this topic. If you do not have lamps with a wide range of adjustment, you can successfully exploit this principle. Another method is to use gray filters. I am thinking of films that are produced in several luminosities by companies such as Rosco and Cotech. Do not forget the savings - no need to buy a full range of filters, a lot is better to also buy them in the roll than in sheets.This allows us to put them before the lamp twice or more times complex.

Only in rare cases, extremely short exposure time is important and that's when you shoota bottle was needed. For lovers of low-cost solutions, unfortunately this is not goodnews. Simple studio lights do not flash time adjustment, and indeed even the more advanced very rarely have this option. I use hardware broncolor Swiss company, whichin the top models of generators provides a degree of control of this parameter. Eventhough the shortest time, I achieve only the lowest powers the flash.

Photographing water in motion

To perform almost every person needs professional tools. Occupation photographer is no exception, but not enough in the studio camera, flash, several tripods and computer.We will need more tools and accessories to be used in a variety of specialties. There must be a professional course, large machines such as computer-controlled milling machine, although this would probably be useful sometimes. Every photographer, depending on the course should complete their own set, which should not be missing tapes, veins, plasticine, scissors, pliers, etc., etc. - could be exchanged for a long time.Are also very helpful for multiple mounting accessories manufactured by companies such as Manfrotto or Foba, but without them it can be to deal with. 
I have never concealed that the pictures I make are the result of combining photography with computer processing. I mention this because already at work in the studio we have to think about editing later. For this reason, the implementation of the photographic material for this work was divided into several parts. Is good practice to draw the everything before the session to clarify the expected results and consider what steps to divide the work. Drawing does not need to be beautiful, but should include all the elements to be included in the frame.
First of all - a glass with ice cubes and mint. Its preparation took a long time, even though the peppermint dough was stuck to the bottom so as not to be inferred, and the bones were made of acrylic and the wicked do not leap to the surface. The same paste and position of everything in an attractive manner cost no small effort. If someone come to similar compositions without difficulty and is looking for work, willing to hire him in his studio as a stylist. To facilitate your work, after setting the frame and focus was to determine the necessary background to where the glasses. This allowed it to be discontinued in exactly the same point, whenever there was a need to. After each set, ice and mint zalewaliśmy gently mix them lightly carbonated, so as not to disturb the composition of the glass.

Depth of Field

The depth of field (DOF) is a parameter used in optics andphotography to define the scope within which the objects observed by the optical devicegives the impression of acute (ie, with clear, nierozmazane contours).
The large depth of focus provides the focus of most elements in the picture, but littledepth of field (the precise focus at the subject item and blurred background) is sometimes highly desirable for portraits and art, because the subject is isolated against the background of the environment.

Immediately, the extent of depth of field are the following factors:
- aperture - the smaller the aperture is left (ie: the higher the aperture, eg, 16 or 22), thegreater the depth;
- the distance at which it is set to focus the lens (the distance between the object and the camera) - the distance is less, the depth of field as well.
- focal lenght

Indirectly, the extent of depth of field is affected:
- resolution and the size of the sensor / film
