It is not easy to break into a new hobby, especially one that is quite difficult to master. It is quite discouraging to be taking photographs only to find them too dark or blurry, all the time. It is not easy to easy especially for a beginner in photography to be able to perfectly grasp all the techniques right away, more so the terminologies that come with the technique. But if you are really quite intent on you wish to keep true to your passion, you have to find a way to take some time to learn, practice and completely embrace these new things starting with the following:
* Shutter Speed. This is the amount of time that the shutter is open, to allow light to strike the Charged Coupled Devices (CCD). It converts light that comes in through the lenses into electric signals into digital images. It can be adjusted with the aperture to be able to capture a specific subject. When you set your camera with a slower shutter speed, more light will get in since it is opened longer. If you try to take photographs using this setting, say photographs of different bodies of water, you will find that this will create a beautiful effect. On the other hand, if you set the shutter speed to a faster speed, you allow less light to come in since the shutters are moving quite fast and this is perfect if you wish to create some sort of freezing effect, so this will be perfect when you are trying to take action shots.
* Aperture. This works hand-in-hand with the shutter speed and it is also sometimes called the AV or the aperture value. It functions to increase or reduce the thickness of the light beam that goes through the lens to strike the Charged Coupled Devices (CCD). When the aperture is opened, it will reduce the aperture value; and when the aperture is closed it increases it. You can try this trick by taking pictures of nature, perhaps in a garden or in the mountains. Take a flower for instance; you can take different kinds of photos of a single flower using different effects. When you have the aperture open, you will be able to bring much emphasis on the flower and its surrounding will be out of focus. However, if you take a picture of the flower with the aperture closed, you can adjust the range of focus so that the other objects will not be lost in the picture.
* Camera Shake. Those who are just beginning in photography will encounter all kinds of problems and one of the many quandaries is camera shake that produces blur. When you cannot keep the camera still, and if it moves while you are taking a picture, you will create a blurred image. You can easily increase the shutter speed to counter this problem; and if that does not solve it, you can also choose to increase aperture too while making sure to using the flash. If the previously mentioned techniques does not solve your blurry problems, then perhaps you are better off with a tripod. While many of the newer DSLR models come with anti-shake features, it is still nice to know how to deal with this problem, especially if you are handling older models.
These are only some terminologies, to help jump start you; do not close your doors for more because there is just so much that you have to learn.
