techniques of photography fundamentals - Using wide angle lenses

A wide angle lens can be a powerful tool for exaggerating depth and relative size in a photo. However, it's also one of the most difficult types of lenses to learn how to use. This page dispels some common misconceptions, and discusses techniques for taking full advantage of the unique characteristics of a wide angle lens.



OVERVIEW

A lens is generally considered to be "wide angle" when its focal length is less than around 35 mm (on a full frame; see camera lenses: focal length & aperture). This translates into an angle of view which is greater than about 55° across your photo's widest dimension. The definition of ultra-wide is a little fuzzier, but most agree that this realm begins with focal lengths somewhere around 20-24 mm and less. On a compact camera, wide angle is often when you've fully zoomed out, however ultra-wide is usually never available without a special lens adapter.

Regardless, the key concept is this: the shorter the focal length, the more you will tend to notice the unique effects of a wide angle lens.

What makes a wide angle lens unique? A common misconception is that wide-angle lenses are primarily used for when you cannot step far enough away from your subject, but yet still want to capture all of this subject in a single camera frame. Unfortunately, if one were to only use it this way they'd really be missing out. In fact, wide angle lenses are often used for just the opposite: when you want to get closer to a subject!
So, let's take a closer look at just what makes a wide angle lens unique:

• Its image encompasses a wide angle of view
• It generally has a close minimum focusing distance

Although the above characteristics might seem pretty basic, they result in a surprising range of possibilities. The rest of this page focuses on techniques for how to best use these traits for maximal impact in wide angle photography.

techniques of photography fundamentals - Tips for sharper pictures

Produces sharp images razor-sharp photography is the desire of many lovers, and a variety of camera features and additional accessories are created to help us produce this sharp photos. From tripod, stabilizer (or camera lens) through photo editor software tool equipped to sharpen the final image.

How to hold the camera

How to hold the camera very influential on the stability of the camera (read: the sharpness of images), read how to hold a good camera.
 

Shutter Speed.

If you speed up the shutter speed, then you will get sharp photos. Remember the standard rule for sharp images when you shoot handheld: "use a shutter speed faster than your lens focal length". Here penjabarannya:

•     If the length of your 50mm lens, shoot with a shutter speed of 1 / 60 sec or faster
•     If the length of your 100mm lens, use a shutter speed of 1 / 125 second or faster
•     If the length of your 200mm lens, use a shutter speed of 1 / 250 second or faster

Aperture

Aperture affects depth of field (area of ​​focus in your photo). Reducing the aperture (increase the number, for example you choose f/22) will add depth of field, meaning a sharp areas in the bigger picture will include objects near and far, so the sharpness of the picture as a whole actually decreased.
Then do the opposite, select a large aperture (small number, eg f / 4), then you will focus sharply only near the focus area. Choosing a large aperture that lets you get a faster shutter speed.
 

ISO

Adding the ISO will speed up the shutter speed and lets you choose a larger aperture. If you are photographing indoors, ISO was larger, but do not overdo it (eg: select ISO 600 for shooting inside the house). choose the ISO is too high (above 800), can cause noise (small black spots) in an image starts to look.
 

Focus

Do not just believe with autofocus camera, check carefully to use the eyes in the eyes of your focal point is located. When photographing the face at close range, make sure the focus falls diarea eye. When photographing an object, make sure the focus is there where you want the area's most sharply. Autofocus camera could be wrong and instead focus in addition to dropping the object that you want.
 

Lens

If you happen to have an SLR camera, choose the best lens you can buy. Good quality lens that can drastically improve the sharpness of your photo. KIT lenses are usually offered for sale as a complete package with its camera quality is usually terrible. My advice, if you will buy a new SLR camera, buy separately between the camera (body only) and the lens. Do not buy a package of KIT. A lens with good quality is usually characterized by a large aperture (eg f/2.8).
 

Sweet Spot Lens

The lens has its sweet spots respectively. Sweet spot is certain where the lens aperture will produce the sharpest images. Lens sweet spot is usually located two stops above the maximum limit the ability of the lens aperture. For example, for the f/2.8 lens is its sweet spot at f/5.6. Then use aperture f/5.6 lens if you shoot with it, your photo will be sharp razor-sharp.
 

Tripod

A tripod is impractical and inconvenient, but if you are "willing to" take it, you'll get sharper photos. Especially if you want to generate the HDR or panoramic photos, let it go bring a tripod.
