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.

Landscape photography is an extremely popular profession. Have a look around your home, and you are most likely to see at least two landscape prints that spoke to you. Photography is an art that has a message. As a photographer you have to find the message you want to convey. If you specialize in landscape photography you might presume your task is easy to complete. As with any photography you have to pay attention to the details, the lighting, shadows, subject, and the equipment.
Black and white landscape photography is the hardest part to attain true artistry because you are relying not on colors but lights and shadows the image will create. The core part of black and white photography is getting the camera to see what your eye sees in color; to bring the highlights and shadows forward with the angle of the picture. Typical subjects for black and white photography are buildings and water. Water provides a contrast to surrounding trees and rocks while drawing the eye. Landscape can cover buildings or bridges among other subjects. Buildings provide angles and contrast you seek when trying for definition and emotion.
For color landscape photography you will need to have contrast between the colors. If the sky is blue and you have blue water below chances are the picture is not going to have the contrast you are hoping for. You will need to take a few minutes to set up the shot and very likely take several frames before being satisfied. Color photography requires fewer skills than black and white photography so if you have mastered the last you will succeed at the first.
You must provide filters for the sunlight if it is a bright day, perhaps a tripod to set up the shot and a professional grade camera to create professional prints. Studying your subject from all angles is also necessary.
Digital photography makes landscape photography easier because you can assess the photo before you leave a site. Again the LCD screen may not show you every aspect of the print so you will want to take a few shots of the same site to ensure a perfect picture.
Even if you are an amateur photographer you can gain professional looking landscape photography. The best way to gain great photographs is to practice with a subject. All photographers start at the same level, some may have innate skills and an eye for the photo, but practice will lead to the best print. Landscape photography probably does not require the skills of wildlife photography; however, it does require skills and practice.

With the new era of digital cameras, photography has become much more common. Almost anyone can afford a camera and most have one. Even many cell phones have a digital camera. While most new cameras are also quite easy to use, there are still many areas in photography where you need to have the knowledge to succeed.
These are some of the most common mistakes made by new digital photographers. If you are an unpracticed photographer, you should try to at least avoid these mistakes.
1. Poor Camera
This is by far the most common mistake these days. Many cheap digital models are only good for either landscape or closeup photographs due to their poor focus. Know your camera: what it can do and what are its limitations. A $200 model should never be used for professional photography.
2. Lighting
Another common mistake is to forget lighting or believe the camera takes care of it all. You will seldom get as good images in dark conditions with a cheap flash than you could in plentiful natural lighting.
3. Cropping
While it is much easier to see what gets in the photo with today’s LCD displays than with an old-fashioned seeker, there are still plenty of mistakes you can make. One thing to remember is that you can crop the image on your computer. That means you will most likely want to include too much space around than too little.
4. Zooming
There are so make things that can go wrong with zooming. The number one thing to keep in mind is to always avoid using the digital zoom. It is a feature found in many cheap digital cameras that basically has the same result as cropping the image on your computer. If you need zoom, only use the optical zoom.
5. Camera Settings
If you are not sure about the settings in your camera, it may be best to use the defaults. If there are several modes, the ‘auto’ mode is usually the easiest to use. You should take care that you use a good format to save the images. Often the high detail mode with the highest resolution should be used, if you are not short on memory.
The bottom line is: if you are serious about photography, you must practice it. Digital photography does not differ much it that sense.
If you do not learn the skills in advance, you are going to have to learn them the hard way, and that will probably mean making these mistakes and more. It can also mean tens or hundreds of lost photos - shots that could have been excellent had you not made a simple mistake.

Right from the beginning, realize that wedding photography and videography services will consume a significant portion of your wedding budget. Also know that it’s an absolute must to book this type of talent as soon as possible, at least 6 months to a full year before the wedding date, especially if you’re planning the wedding during the summer or holiday season. You’ve got to get a head start and although that offer from your Uncle Vinny to photography your wedding (for free!) as his gift to you sounds tempting, resist the offer. This is not the time for amateur shots.
It’s important to move at a fast pace, but never skip the background check. Checking references is a must but so is being allowed to view the prospective photographer’s images from a previous wedding assignment. Don’t rely on the quality of their portfolio which is usually a collection of the best pictures from multiple weddings. You want to view one whole wedding, from start to finish. Also check with the local Better Business Bureau as they’ll have on file any complaints made against the person or company.
