The Lytro is nothing new. Still, I could not help but write something about him when he finally held it in my hands. Looking back, this is a light field camera that captures a different type of information than is recorded by conventional cameras. This distinction allows the image to be changed in many ways even after the picture is already recorded in memory. The photographer can change the focal point, self shot or more recently even the perspective image.
More specifically, while the optical system of the ordinary cameras converges self shot the light rays to a focal point, self shot Lytro has a group of microlenses in front of the sensor that these same dispersed rays. Consequently, the camera captures not only the intensity of light reflected self shot by objects in the scene, as well as calculates the trajectory of the radiation. The result is that it can deduce how a particular image would be if it had been focused differently. In practice, this means that the photographer can shoot images self shot without worrying about focus, which can be changed later.
Of course, there are numerous reservations as to this process. The first is that the resolution is degraded. Because of Manira as the pictures are rendered, there is no direct relationship between the resolution of the sensor and the final image. In any case, the images are converted to JPEG end with only MP 1.2.
Another issue is that the Lytro sensor is very small. With about 6.5 x 4.5 mm, it is not much larger than a smartphone sensor. In practice, this means that the shallow depth of field effect can be achieved only when the camera is very close to the depicted object. Even in this situation, the Lytro hardly produces the same legal blur a wide aperture DSLR. In other words, the most fun part of Lytro, ie refocus photos, is somewhat limited. self shot Perhaps for this reason, manufacturers have decided self shot to install a lens of relatively long focal length (equivalent to 43mm - 341mm in 35mm format) that magnifies objects and creates an appearance of depth shallower field.
Finally, the Lytro is still attached to the conventional laws of physics. Therefore, exposure, white balance, sensitivity and other crucial factors of photography apply to it the same way as for any camera. At this point, moreover, the Lytro really is not exceptional. For those who are used to the 4: 3 format, compose in 1: 1 (1080 x 1080 pixels) is also a bit strange.
Despite these issues, I must admit that the camera is so much fun to use. Its unusual shape and its magical pictures give a feeling similar to that 19th century people must have felt regarding trinkets as the Zoetrope. The Lytro is undoubtedly self shot very charming. I do not have so much fun with a camera since we tested the Instax Mini Fujifilm. Here is a picture that I did Cho'Gath of the Terror of the Void with it (click the image to change the focus).
