Seriously .. Large

Hello Friends and business colleagues,

Ahh … wide-angle photography, probably one of the easiest types picture taking, but also one of the most difficult to excel at.

Have you ever tried to put 30 people in a single photograph? You would try to stack them, some of them on the floor or even ask some of them in the back to skip to the press of the shutter!? You are also trying to ensure that are able to see the faces of these people in the photograph. Difficult if your Camera Lens is not wide enough and you have to move further back to give place, which may not be possible if space is limited. When shooting indoors with flash, you can go back even give you an underexposed photograph, such as flash often not is powerful enough to reach longer distances.

Apart from the utilitarian function to get good photos of the group, wide-angle shots allows you to portray the scene in detail with unusual and sometimes exaggerated perspectives. This is especially true of Super Wide Angle. Smaller items can to appear larger than the large objects within the same scene, effectively shifting the balance of the composition of the image. When used well, can draw attention on the subject of interest in the foreground, at the same time while preserving the context of the whole image, showing the location or event in the background.

Choose your interest in the foreground with caution

-Great Options

Lenses are classified by their focal length. Usually, the lenses fall into one of these categories:

° angle super wide (10 ~ 24 mm)

· Wide Angle (24 ~ 35 mm)

· Standard (about 50 mm)

· Telephoto (70 ~ 300 mm)

· Super Telephoto (300 mm and beyond)

These numbers indicate the focal length, which describes the field of view lens that attainable. Indeed, the field of view of a 50mm lens is considered as an approximation to what the human eye sees. A Digital Slr owners can choose from a variety of lenses ranging from a wide-super all the way to a super telephoto. But what about the rest of us?

owners digital Compact Camera are not left out of the picture. There are a multitude of wide-angle adapter for digital compacts, both made available as accessories, as well as by other manufacturers. These can be attached through wires or bayonet lens mounts on their bodies. There are also some third party lenses can be attached magnetically!

-Focal length multiplier

Note: The "focal length determines the lens' field of vision, which is the last angle of view Instead of using this lens. 'Field of view crop "is often referred to as" focal length multiplier "for the sake of simplicity.

Digital photography from the hardware perspective, is based on the principles of 35mm film. For a photographer who shoots with film, there is no such thing as a "focal length multiplier, because for them, everything is 1x. This means that a 50mm lens is a 50mm lens. Not so for a digital SLR. One objective of 50 mm almost becomes a 75mm lens, when connected to a Nikon D200 digital Slr Camera. This is due to "coordination length multiplier "1.5 x makes the 50mm lens to take a field of view equivalent to a 75mm lens.

Shooting wide angle is basically a way of representing a scene using a wider field of vision, which in turn is achieved by using a lens with a focal length less than 50 mm SLR camera with 35mm film. These days, with the proliferation of digital Slr Cameras, there may be some confusion about how to calculate the focal lengths.

To keep things simple, we can use this golden rule. If you are using a 35mm SLR camera, the focal length multiplier is 1x. If you are using a Digital Slr Camera, the focal length multiplier can be any of these, depending on the model of digital SLR camera: 1x (eg Canon 1Ds Mk II) 1.3 x (eg Canon 1D Mk II), 1.5 x (eg Nikon D200 or D70) or 1.6 times (eg Canon 30D).

To get the actual focal length (and both the field of view as possible) of your lens, multiply the focal length of the lens with the multiplier.

Example 1

Nikon D200 (1.5x multiplier) a lens of 17 ~ 70 mm

The real extent of this combination focal length is 25.5mm-105mm, achieved by multiplying the area with 1.5 camera

Example 2

Canon 1Ds Mk II (multiplier is 1x) with a lens of 70 ~ 300 mm

The actual range of focal length of this combination is still 70-300mm.

Example 3

Nikon F5 (35mm Film Camera with 1x multiplier) with a fisheye lens 15mm

The actual focal length of this combination is still 15 mm.

The reason behind the focal length multiplier is the size of the recording media, the CCD or CMOS. Different cameras different sizes using CCD / CMOS, for different reasons, for example. to make a smaller camera and better energy efficiency. For Digital Cameras compact that do not fall into the category of digital SLR cameras, focal length multipliers are rarely used because they have interchangeable lenses. What we do have adapters are wide-angle or telephoto adapters. A wide angle adapter can be called an adapter 0.7x wide. What does this number is this adapter shortens the focal length of the lens incorporated by multiplying by 0.7, creating a wider field of vision.

Super wide angle shots sometimes appear distorted, but show much more in the background, lending a picture frame

-Focus Wide Angle Lens

A feature inherent of the camera lenses is that wide angle lenses come with more depth of field compared with telephoto lenses. This approach reduces errors in some extent, which means you can focus on almost anything around the center of the image and get an acceptable image sharp. In this case, a small gap increases even plus the possibility of a sharp image. For best results, however, we can use the "1 / 3 of the distance rule." Look inside your visor camera, the estimate of the distance from the nearest point that is visible in the viewfinder, until the last point that is also visible in the viewfinder. Focus on a point is approximately one third of the distance away from you. If you can not use auto focus effectively on this issue (perhaps due to low light levels very low or early change in the morning on a mountain), we can estimate the distance and focus the lens manually using the distance scale on your lens. A small opening (eg F16) gives you more depth of field, so if possible. That's why it's good to carry a tripod, which allows you to use smaller apertures without movement of the camera.

"Composing with wide angle lenses

Wide angle photography has its own set of challenges. Despite that lets you show over the scene, sometimes less is more. If not properly framed, wide-angle image can include distractions that hurt the image, because a wide angle lens sees a wider field of view than a normal lens. Therefore it is good to fill the frame well, that compose it, so that only the necessary elements are included. Landscape photography is a classic candidate for the use of wide angle lenses. In order to shoot landscape photography interest first map is important. Wide angle lenses allow you to include a substantial part of the knowledge acquired in the frame, so use it also for the choice of a close that is really interesting.

When shooting super wide angle, you can get away with a slower shutter speed due to the focal length minimizes errors short slight movements of the camera, opening new possibilities for photography. An example is holding your hand SLR camera on a busy street busy downtown, capturing a clear image of your subject while rendering the pedestrian traffic like a blur because the shutter speed slower.

Attention wide angle

Exercise more care when handling your DSLR or Digital Camera with wide angle lens / adapter. Some wide angle lenses protruding glass is more exposed and susceptible to accidental contact with dirty fingers or worse, could end up scratched. If the lens accepting an UV filter, get one. It will protect your lens from many dangers. Many wide angle lenses allow you to focus closer than a telephoto lens, so a lens hood help in some measure to protect the lens of his over-zealous attempts to get one more shot.

Wide angle photography is exciting, go out and experiment!
