Welcome to the typical plight of the first time SLR purchaser.

Unless you're a fairly serious hobbyist (in which was you can probably stop reading this article), you might be a little baffled at all your lens options as an SLR owner. You're probably asking yourself which types of lenses you need, and what all those crazy letters and numbers in front of the name mean. How is a poor consumer to choose?

Let me make it simple for you. I'm not going to give you a complete course in everything you need to know about camera lenses, but hopefully after this, you have some idea of that you want to buy. First of all, let me state that unless you have a good reason to choose otherwise, you'll want a zoom lens. As you probably know, a zoom lens allows you to change the magnification of your lens (we'll start calling it by its proper name, the "focal length," from now on. These are extremely convenient, and very high quality these days, so there really is no reason to choose a fixed focal length, or "prime" lens.

So, the first thing you'll notice when shopping for zoom lenses are the focal lengths. Focal lengths for zoom lenses are designated using the number hyphen number system, such as 18-70. These numbers represent the focal length in millimeters, and the larger the number, the more "zoomed in" your picture appears. Assuming you're using a digital SLR, this particular example would zoom from a moderately wide angle view (28mm) to a moderately close up view (70mm). This would be a good, everyday lens to carry around.

The second set of numbers represent the "speed" of these, which basically means how much light the lens lets in. In photography, the more light, the better. This is what the "f" number means, and the lower it is, the better. For example, a 18-70 f4 lens is better than a 18-70 f5.6 lens. Sometimes, you'll see two numbers, like "f4-5.6," which means that the speed gets slower as you zoom out. This is perfectly normal, but its something to be aware of.

So, which lenses should you buy? Well, the easy answer is to buy something with a huge range, like 18-300, and be done with it. However, a general rule of thumb is that the longer the zoom range is, the poorer the image quality. However, many of these lenses are a lot better than they used to be, and for many casual photographers, the image quality trade off is worth the convenience.

Many beginners find digital photography rather challenging and rightly so. Today, more and more digital cameras are being created and it seems like the more digital cameras they make, the more difficult they become to use.

I own a Canon Powershot S3 IS. I purchased this digital camera about a year ago and I still haven't utilized all of the awesome little features this camera has to offer. Now you may not want or even need a camera with tons of features. It really depends on the type of pictures you plan on taking.

Regardless of the camera you own or are planning to own, you should have a well rounded knowledge of digital photography. I hope the following 20 tips for taking digital photography will prove to be useful in your quest for taking better photographs.

1. Know your camera. One of the biggest mistakes you can make is not taking time to learn about the features of your camera. Don't be lazy. Read your instruction manual.

2 - When shooting sunny outdoor shots, try adjusting your white balance setting from auto to cloudy. The auto setting will make your shots appear too cold. When you change it to cloudy, it will increase the warmth of your pictures.

3 - If you are looking for superior image quality, the ability to use a variety of lenses and print large high quality photos, then considering a Digital SLR Camera.

4 - Use your flash outdoors. Sometimes, even on a sunny day outdoors, there is still a need for a flash. If the sun is directly over head or behind your subject, this can cause dark shadows to appear on the face. The flash will help lighten the subjects face.

5- Sometimes simply turning your camera and taking vertical shots can make a world of difference. Experiment more with vertical picture taking.

6 - Do not put your subjects directly in the center of your shot. Move your subject off center to inject more life into your photos.

7 - Learn how to hold your digital camera. One of the most common problems beginners face is the shaking of the camera because they are not holding it properly. Of course, the best way to avoid shaking the camera is to use a tripod. If you don't have a tripod, then you should be holding your camera with two hands. Put one hand on the right hand side of your camera where you actually snap the photo and the other hand will support the weight of your camera. Depending on the camera, your left hand will either be positioned on the bottom or around your lens.

8 - Learn about the "Rule of Thirds". This is a well known principle of photographic composition that every beginner should become familiar with. Do a search online and you will find many tutorials on this subject.

9 - Look at other photographers work. Just spending time studying the work of other photographers can provide loads of inspiration.
