Like all things technological, the world of digital cameras and photography is filled with acronyms. Here are some of the most common acronyms related to digital photography, together with what they actually mean.
CCD
Charge-coupled device is a system that converts the light signals to digital data. The name CCD is often used for the whole sensor that takes the photograph, though it actually only refers to a part of it.
LCD
Liquid crystal displays are used in digital cameras as a viewfinder. Usually the screen is around two inches measured diagonally and can also be used to play back images taken earlier. LCD screens are also used on some television sets and computers.
ISO
International Organization for Standardization is an international body that sets standards. In photography there are two relevant standards: ISO speed for film and ISO exposure index for digital cameras.

With the onset of the 21st century, photos can be manipulated and altered in many ways using digital imaging and computer aided techniques. Digital photography started a significant change in photographic technology and changed the nature of photography significantly.
Nowadays, the number of photos you can take is much higher, so you can afford to make mistakes. Also, a photograph can often be remedied on the personal computer, even if it was spoiled by too much lighting. While that has made photography more beginner friendly, it is still far from an easy hobby.
Photography has been present for more than a hundred years and yet new innovations are taking place even this day. Looking at it, one has to surmise that photography will develop again in the future. It’s never too late to get into photography and even now it’s too early to stop learning more about it.
Cameras have certainly come a long way since the early camera obscura. Today the digital point and shoot cameras used by many fit easily in one hand and are fully automated. You even need none of the film rolls present in cameras from a couple of decades past, but can store hundreds of high quality photographs on a memory card less than a square inch in size.
If this is the state of photography today, what may the future hold for us? Technologies such as high dynamic range (HDR) imaging and specular reflection have already been developed. They will probably enter the consumer market within the next few years. More long term plans on photographic technology include various forms of 3D modeling.
Regardless of which one of these technologies you will have in your digital camera a few years from now, one thing is certain: your camera will still not take the pictures without your guidance. Choosing the target, the angle of view and cropping the photograph will still be left for you to take care of and excel in.
If you are into photography, you probably want to get better at it. That requires practice - a lot of it. However, it is often helpful to be taught about the theory, too. That’s why online photography courses have become a popular method both for new photographers to get used to the art and for more experienced photographers to hone their skills.
