Panoramic Photography


We saw the ultra-wide-angle shots, the goals of its kind to be produced uniquely on the basis of their unique angle. There are other special classes of optics can be even more corners of a hot area: fish-eye lenses - made with special curved - and panoramic cameras - they have the ability to walk, make it or the optics, the field for more angles
Today we will look particularly attractive in this kind of photography and learning how magnificent panoramic images to a series of photographs "parallel" to get.

Note: Some cameras can even rotate 360 ​​degrees on the frame and the remedying of environmental damage.
In the past - what I read in the rule, while the film was - panoramic photo of the first, the establishment of specific equipment is expensive, usually reserved for professionals and enthusiasts are once again very driven and too much time in a dark have room to spend time together and try to "push" to take up a paper, as well as possible programs created earlier. For these reasons, which is dedicated to these conventions really was, in most cases, an expert in the field, saving time and money (I know more "panning" Throughout my career, all the people with very clear ideas of subtraction " special circumstances. "- When Michael Nichols, National Geographic has a picture of a redwood tree length of 115 meters," glue "together with a team of 84 frames of 12 people, 1 million units ...
Today, applications, everything is easier ... Much easier. We do not intend to give you the hunting of small programs, more or less effectively, in order to obtain panoramic images, but to give you some helpful tips to help you implement it themselves (with a much higher quality). In fact, although challenging, are software in circulation was not very good at managing large files imagine should also complete control over the results that a good photographer should constantly monitor to be adjusted.
Of course, manage the use of software, the photo was taken, is necessary. My advice is, with what is provided by the manufacturer to start the camera. Canon and Nikon, for example, imagine a discrete solutions. An offer in fact the buyer of his models, compact bridge, PhotoStitch, while Nikon Panorama Maker on a program of ArcSoft, complex has been developed, but also much more complete. Anyway, as usual, Photoshop Elements version 7 (I think)., Strong is the potential of its Photo merge increased and thus the creation of panoramic images, using Adobe reference point.

The next article, in fact, we see how we can make a panoramic picture with this program very. For now, it is important that some basic simple rules that are required to follow a good series of photos that can begin to develop our panoramic images.

Eight basic rules of photography criticism
A panorama mode. Many cameras to medium-low, in fact, almost all of what is commonly called "Panorama mode." Use it. In fact, you can create a series was used images to create panorama ". Use this feature to reduce the problems of duplication, if they used? Plan for the intersection of the images? To create a panoramic image . panorama mode, typically, the camera activates a number of functions 1) of the display machine shows the last image on the one hand, and secondly, the "live" with what is the goal. Strangely, it is very useful to the picture most properly 2 above. else) if we set the camera to this mode, auto exposure No picture to picture. You can imagine the benefits in terms of the homogeneity of the total light in the final image, and reduction of splicing of the software in the post-production.
Two. Overlapping. The overlap between the images is one of the most important steps in the realization of panoramic images. By clicking on the "slide" along a straight line Click to renew on the following image, much of what has been a previous, dangerous. Nobody wants to see (the Grand Canyon of the Upper Engadine, for example) and a thin white line between them ... Missing part of our landscape! Good idea to take each frame for 30% of previous good ... Sometimes a little more, sometimes less. I think some trust in your photographic media is ideal for understanding "what percentage" is needed to cover the succession of different images.
Three. Stay on this level. When the panoramic image consists of several frames, is four or five at most, not very important. But if the number of images on the horizon to keep the same level is easy. The goal is actually a group of curves Lens: If it a series of images at the same height, the details of the image through the lens, the angle sensor with a memory. For example, if a bit "number distribution of objects in the background, affecting different angle sensor relative to the previous frame, and if the pictures are a sequence accession number" fan effect "to send the ball Editing Software Review. Objects itself, but at different distances at different angles, is "recognized" by the computer as a different ... Can you imagine the results. # 6 on the image to see a demonstration of what I just said.
Four. Exposure to the eyes! If the camera you do to merge the images in post-production, not with a panorama mode (like a digital SLR, for example.) Provided, that is most dispassionate advice I can give you the exposure be implemented manually adjusted. See Figure 7 and you will understand. Note the differences in hue in the air? The software was to "repair" the hole in the position of the exposure to the shopping center, but failed skyline ... Manual setting of aperture and shutter speed on all the pictures in the group for an identical value, he was very driven error.

Five. Beware of moving objects. Moving objects on the stage - people, cars, birds, etc.. - Can double-edged sword. In fact, the subject of some movement is always fun, but be careful they are not too many! First, because too many things to move the ball to send the software (especially when the topics are image recognition along the main trunk lines), and secondly, that they only cause confusion in general. In any case, only the amplitude of the scene is stored, an inevitable moving objects. We try to make sense.
6th Wide angle?. This kind of perspective, we talked a lot. We know that the following areas: 20 to 50 mm focal length wide angle lenses are kept, according to the so-called ultra-wide-angle-20. Panoramic photography, really using the media, which is also part of the recovery drive should not. Distortion "physiological" Because these goals are always waiting. The best solution is to provide a perspective for the use of slightly less than 50 mm, while taking a few pictures of what you usually travel to and once completed, the program does the processing software. We believe him to fix things.

Seven. Left - right, left - right .. No matter which "direction" is made, or from right to left or vice versa. The most important thing is always the same horizontal line, not the nature of the focal length and exposure Touch. Border, the image may be on the right side of the picture, then left, then the central role. If the program that we use is good, no problems. That would be enough to forget the reviews 2 ... A lot of overlap.
Eight. Vertical panorama. As for vertical shooting, with a view stretching from the bottom up often escape the eye not in the "start" a lot of training. It will continue, perhaps a bit more technically convenient (to deal with the stand vertically, is not exactly the best in life, but it really depends on the nature of the present head), but the principles are exactly the same.
