There has been serious concern regarding the protection of online data as a result of problems with computer hacking. There are safety measures that you can take to protect your photographs on the computer.

One is digital watermarking, which is the process of embedding information into a digital signal that can be used to verify its authenticity along with the identity of the owners. The signal where the watermark is embedded is a host signal .A watermarking system is divided into three steps, embedding, attack and detection. If a person makes a modification to a stored watermarked digital signal that is an attack. Detection is when there is an attempt to extract the watermark. In visible digital watermarking, the information is visible in the picture or video in the form of a text or logo, which identifies the owner.

In most countries, including the US, your photos are copyrighted automatically when your photos appear online. However, under special circumstances, you can also file your photo with the US copyright office.

Another method is called hidden layers. This is when you place the actual image behind a transparent foreground image. The online image appears completely normal but it cannot be right clicked and saved. If they try, the result will be a blank foreground image.

You can disable right clicks by letting your visitors know that you are serious about image protection and when they try to save they will see a notice instead of save as.

There are different options on which camera lens to use when photographing your subject. The type of lens that you would use would depend on what you are trying to accomplish with your photo, Lenses can add more creative control.

A wide angle lens exaggerates depth and relative size in a photo. It exaggerates the sizes of near and far subjects and has closer minimum focusing distances. This lens enables the viewer to see a lot more in confined spaces. A wide angle lens is great for capturing expansive landscapes.

A telephoto lens are used for enlarging distant subjects and can normalize the difference in size and distance between near and far objects. Using your camera, you can fill the frame by zooming into the picture with a longer focal length filling the frame entirely with your subject. Telephoto lenses are also used for landscape photography as well as wildlife photography.

A macro lens is used in macrophotography or close up photography. This is about shooting pictures of small objects and filling the frame with tiny objects. Most cameras have a macro mode, close focus, which enables you to get a sharp focus within a few inches of the subject.

Point and shoot cameras have a digital zoom that performs a similar function to the telephoto lens in that it magnifies the image. However, digital zoom does not really zoom; it just enlarged the image by taking a portion of the image and enlarging it to full size.

In order to prevent someone from mistakenly deleting or overwriting some of your photos, you need to take action to back your files up. It is also a good idea to make your archived photos read only and password protect the photos folder with an easy password. You should store two backs- up copies after each photo is captured. They need to be stored in a cool, dry place with a constant environment and minimal need for movement. Be sure to store the media in a plastic bag prior to storage if there is a chance of humidity.

The primary method for consumer back up has been CD, DVD and Blue-Ray. The methods are inexpensive and very compatible. Some removable media only lasts five years, at which time you would have to transfer it over to new media.

External hard drives can store a lot of information in a small area, and permit the back up data to be accessible and modifiable.

Large corporate back- ups use the tape back- up method. However, consumer models have not kept pace with the storage density that hard drives have.

The photographer who uses a compact digital camera or camera phone usually takes JPEG photographs, which saves storage space. Each batch of photos should be backed up in two copies on removable media. Archived photos should be transferred to new media every five years to prevent corrupt images by keeping the data fresh and the storage technology up to date.

Color is an instrumental element in creating images. The various functions that comprise a photograph are what keep ones interest in the photo. Color and time of day all influence a photograph.

Color has two functions in photographs. The first is to grab the attention of the viewer for an extended period of time and when the viewer’s eyes wander from the photo, Very saturated or intense bold colors keep the viewer’s focus and grab their attention seen in a sunset Using a mix of contrasting colors is another way to grab a viewer’s attention, seen in an image of fall colors consisting of red, orange and yellow leaves.

One of the most powerful functions of color is that color sets the mood of an image. This is a more subtle application .Different colors create different moods. The color blue elicits feelings of calm or cold. It is a reflection of how one perceives the color in nature, such as in peaceful cloudless skies or a large calm ocean. The color green offers a feeling of lushness and freshness that is associated with spring and new growth. Yellow, orange and red are warm tones that exhibit feelings of warmth and comfort. You often see these colors in flowers, foods, etc. Aside from the vivid, bold colors, the use of light also creates a mood in an image. When photographs are taken before sunrise and twenty minutes after sunset, it is presented in a soft, blue light.
