What You Should Know About Your Digital Camera Lens

The lens is the most important part of a digital camera and there's every reason why camera owners need to get to know this component. Lenses control what a camera captures in terms of the image, perspective and quality and how much light can get in. Adjusting this part plays a vital role in capturing quality images.
The lens is described through its focal length which can either be the single type or the one with various ranges. A lens that has a single focal length is known as the prime lens while the type that has a range of focals is referred to as a zoom lens. Most digital cameras today feature zoom lenses including the point and shoot models.
Cameras having a zoom lens can accommodate different focal lengths within its range. This can be done just by turning a ring around its body. In most cases today, though, this can be done automatically with a click of a button.
Through the focal length, the angle of view for a specific camera sensor size is determined. For instance, a lens with a full-frame sensor can give the same angle of view similar to a 35 mm film camera. A smaller sensor, on the other hand, means that the angle of view is smaller as well.
A short focal length means the angle of view is greater while a lens with longer focal length features a smaller angle of view. With a wider focal length, you are able to take an image at a closer range. With a wider angle-of-view, on the other hand, you can capture a larger subject at a distance. If the angle of view is narrower, you can take a small subject from a specific distance.
Another part of the lens is the aperture. This is the opening inside the lens that allows light to pass through. Wider apertures are also known as bright and fast apertures because of their ability to let more light in. With more light, faster shutter speeds can be achieved.
Apertures are indicated through numbers. A small number means a large aperture such as F/2while a large number implies a small aperture. With prime lenses, they only have one particular aperture. Zoom lenses, meanwhile, have two or more apertures.
The mount is also a vital component of a lens. This is the one that connects the camera and the lens itself. This is often used with interchangeable lens, some of which can fit different types of digital cameras. They can be used directly or through a special adapter.
When using mounts, make sure that the lens is also compatible with the camera. It may be that the lens and mount fit together but the lens is not suitable for the camera due to a different sensor size. Most camera manufacturers produce their own lens mounts that can be used with the same brand of cameras only. But it is also possible today to get a mount from a third party manufacturer which can then be used in varying types of lens and camera.

Canvas Art - The Perfect Gift For Every Occasion

It is not always easy to find gifts for certain friends or family members. Some are very specific about the presents they want, while others already have everything they could ever need. It is very difficult to find gifts for these people, unless you come up with an amazing idea.
Canvas art prints can be gifted to just about anyone. They are appreciated by teenagers, seniors, men and women. Everyone has at least one favourite picture that can be used to create an extraordinary art piece that will be treasured for years to come.
You can use just about any picture to create canvas art. All you need is a digital picture, an old fashioned photo negative or slide, which you provide to your canvas and fine art printing provider. Choose the size of the print or completed canvas you want, and in a few days you will receive your order. Wrap it in themed packaging paper, compose a nice note on a gift card and you are all set.
Before you decide on the picture you want to upload to your canvas art supplier, think about the home of the gift recipients. Do they like modern art, or something more contemporary? What other art pieces do they already have? Are they following a theme? If they have, for example, an African theme going throughout their living room, you may consider canvas art prints of grazing giraffes, or maybe a sunset on a river in the Serengeti plains. Do not worry if the home has no particular decorative style. You can always use a unique family photo, or see if you can get your hands on one of their most favourite vacation snapshots.
Your photo canvas printing provider will ask for the measurements of the pieces you are ordering. When you make your selection, think about the wall space your friend or family member has available. Do not order an over-sized piece when the recipient lives in a small apartment or loft. Instead of being impressive, your large canvas art may then end up being rather useless.
Also consider your gift recipient's personal taste. Do they dress conservatively, or do they not mind being aggressive and bold? What colours stand out? Are they conservative and prefer one single shade, or do they like to mix up their colours and be flamboyant? All these observations are important for your picture selection.
Because you can virtually pick any picture you like and turn it into canvas art prints, you will have an unlimited supply of gift ideas. Family photos will be top hits at wedding anniversaries, on Mother's Day, and at Christmas time, while scenic or abstract pictures can be used any time, even on birthdays, and graduation celebrations. To celebrate the birth of a newborn, transform the child's first picture into a nice piece of art that can decorate the nursery. Such gifts are treasured, and will be passed down through generations.
Quality canvas prints can look stunning for almost 100 years when protected from direct sunlight. They can be delivered to you in a few days, just in time for the next special occasion. So, have you picked out your favourite pictures yet?
