Stitching errors are a common problem in panoramic photography, where the photo stitching software made a mistake in lining up the images when it stitched them together. After stitching your panorama you might see some places where objects have been distorted, misaligned or cut in half during the panorama stitching process. Here are the six most common causes of stitching errors. 1. Not enough overlap between frames. If you don't allow enough overlap between frames when shooting, your software may not be able to stitch the frames together properly. 2. Distortion. If there's a lot of distortion in the original images, it can make the images much harder for the software to stitch together.[..]

Panoramic digital photos cover a wide angle of view. In its extreme a panoramic photo can cover 360 degrees of view. Such panoramic photos are for example taken from a sky scraper to convey the view it provides. Most new digital cameras provide a panoramic mode that supports such photography. There is no formal or definitive definition of what a panoramic photo is. It is common practice to define panoramic photos as such that cover a wide angle of view. How wide? A common definition is "wider than our eyes can see" - or in other worlds - provide an artificial view that otherwise we could not have gotten by just looking at the scene (without moving our head left and right or up and down[..]

The majority of consumers who purchase a new digital camera opt for a point and shoot model. Many wouldn't and probably shouldn't, consider an SLR. However, for those who want greater control, an SLR camera can certainly be a good option. Point and shoot cameras produce great pictures, but an SLR is for those who want more. Most of the basic point and shoot cameras offer all kinds of automatic functions to allow us to take pictures with a minimal amount of fuss. No messing around with focus, aperture settings, shutter speed, or even flash in most instances. Their ease of use, affordability, and smaller size has kept point and shoot cameras on the top of most consumers shopping lists.[..]

The world we live in is three dimensional, we see in three dimensions yet when we photograph we see only two dimensions. In order to create images that add a third dimension we need to add some perspective or depth. The big question is what is perspective and how do we add it? Because we can't see a third dimension in our images we need to create an impression that there is depth to the photograph. This is created by the relationship between elements in the image showing the space between them and giving a sense of depth. Our brains need to discern which elements are near and which are far away. If we can do this then the sense of perspective is created and the third dimension is added.[..]

Samsung WB500 Review

Posted by admin

The Samsung WB500 impressed me a lot. It is a digital camera with a long zoom lens (10x zoom) that comes in a relatively small body. Although it is still too large to fit into a pocket, Samsung has ensured the WB500 is still small enough to take most places with you. As well as the obviously capacity for zooming in on distant subjects the WB500 also has wide angle capabilities. The minimum focal length of lens is equivalent to 24mm in 35mm format. At the time of its introduction this was the first 10x lens to offer such a wide angle. A wide angle lens is great for packing wide landscapes or groups of people into a shot. In addition to the usual selection of scene modes Samsung has also[..]

To capture clear images, high-quality cameras generally use lenses that require manual or automatic focusing. Unless the lens is focused correctly, the subject will appear soft and blurry. In contrast, the majority of simple cameras, including cell-phones, disposable and inexpensive snap-shot cameras use a fixed-focus lens that does not need to be focused. Fixed-focus lenses, also known as focus-free lenses, are designed to render everything in a scene in focus. Fixed-focus lenses are not the same thing as auto-focus lenses. The automatic mechanism of an auto-focus lens still must adjust the lens to achieve maximum sharpness. A fixed-focus lens, on the other hand, never needs to be[..]

As someone who is passionate about, you are probably interested in knowing how to include more depth of field in your photos. There is a lot of literature on this subject. If you're a professional photographer, you've probably learned some things about wide angle (shorter focal length) and telephoto lenses (long focal length). For years photography textbooks and magazines have been promoting the idea that a wide-angle lens provides more depth of field compared to a telephoto one. However, if you type 'depth of field' on Google, you will soon come across a lot of articles arguing this assumption. Recent tests taken by experts, including several photo magazines, have proven that,[..]

Today, though, opinions and expectations have changed. Today's consumers want the best that technology has to offer on all of the features.

One of the best digital photography tips involves something know as depth of field, or bokeh. This is where part of the photograph is in sharp focus while the rest of the image is out of focus, or blurry. This technique adds lots of interest to a photograph by separating the main subject from the photograph and drawing the viewer's attention right to the area of the main subject. The blurred background does not compete for the viewer's attention. You can do a couple of things to create an image with satisfying depth of field. One way to accomplish good depth of field is to separate the main subject far enough from the background so that the background is not in focus. For instance, if[..]

The way a subject is reproduced in a photograph can be very different from how it looked to you as you took the picture. When you cast your eye over a scene, everything in it seems more or less equally sharp, but sometimes in the finished shot only part of the subject appears acceptably sharp. This zone of sharpness is called the depth-of-field, and it extends in front of and behind the point that you actually focused on. The size of the zone is determined by three key factors - the aperture of the lens, the focal length of the lens used, and the distance you are from the subject. Varying these three elements allows you almost complete control over the depth-of-field in a picture. When[..]

type="text/javascript"> Portrait photography is all about the subject. Most portrait shots will blur or soften the background so the subject completely dominates the photograph. To achieve this effect, lenses between 50mm and 135mm lenses are often used. Standard zoom lenses, which usually come together with a camera body, cover this focal length range, and are therefore quite suitable for portrait photography. Sometimes, however, it is necessary to use a large aperture lens with an even greater maximum aperture. In these cases 85mm lenses are the ideal option, especially if portrait photography is a serious pursuit. Some portrait lenses to consider are: - EF85mm f/1.2L USM. This medium[..]

It's very useful with portraits, close-up and macro photography. When done properly it can isolate your main point of interest and will give your prints more depth and better composition.

It's useful to think of telephoto lenses as telescopes for your digital SLR camera. Like a telescope, a telephoto lens enlarges your subject, bringing it closer and making it appear larger in your viewfinder and on your camera's digital sensor. Lenses with a focal length longer than that of a 50mm standard lens can be classed as telephotos. In practice though, 85mm is regarded as the shortest telephoto focal length for fixed or prime lenses, while for telephoto zoom lenses, the short end of the telephoto range starts around 70mm, as in a 70-200mm telephoto zoom. The longer the focal length of a lens, the greater its magnification. Thus a 100mm telephoto lens gives twice the magnification[..]

Long lenses Telephoto lens settings allow you to fill the frame with distant subjects. But the ideal maximum focal length to take with you will depend on your holiday plans The main purpose of telephoto lens settings is that they allow you to get 'closer' to a subject without having to move your feet, magnifying the image in comparison with shorter lenses. They are essential in situations where it is impossible or unwise to move within a certain distance of the subject. But whilst the use of long telephotos with sport and wildlife subjects is usually essential, most subjects will occasionally benefit from the use of a more extensive zoom.

Anyone with children has been in a situation where you'd love to get some good photos of your little darlings in the school play. Unfortunately, the last time you tried resulted in tiny faces barely recognizable. This was due to the distance and the fact that the flash didn't carry too well causing a weak, grainy enlargement. Since you have to arrive early anyway, reserve a front row seat with a prepared sign and take a few snaps of your made-up, costumed kids behind the scenes using the props as a background. Snap a few full length photos and some closer up. If you have more than one or another player is available, have the children act out one of the skits (a highlight if possible).[..]
