Digital photography

Digital photography has opened new avenues for amateur and professional film makers alike. For most movie makers , the backup of digital photography offers unprecedented freedom to get the best shots. No more worrying about wasting that precious piece of film running out, in addition to not knowing for sure that anything worthwhile is on it!

Resolution refers to the 'image-sharpness' of a movie file, and is usually measured in dots (or pixels) per inch (DPI). It also refers to the image-sharpness that printers and monitors are capable of reproducing. Depending on your particular needs, movie files can be scanned at various resolutions. The higher the resolution of a document, greater the image-sharpness, and larger the file size will be.

With digital photography printing in mind, the first thing you need to ensure is that you download the pictures at their full resolution. If in the end, you have 72dpi (dots per inch) pictures, your print quality will be useless. A 72dpi resolution is good for viewing on your computer screen, but an image with 200 to 300dpi will give a good quality 8x10 inch print.

Pixel is short for 'Picture Element.' It is the smallest part of a digital image, and each image is comprised of thousands or millions of pixels. This basic unit, from which a video or computer picture is made, is essentially a dot with a given color and brightness value. The more pixels an image has, the higher the resolution of that image will be. One Megapixel is equal to one million pixels.

Joint Photographic Experts Group (JPEG) is a standards committee that designed this image compression format. The compression format they designed is known as a 'lossy' compression, as it deletes information from an image that it considers unnecessary. JPEG files can range from small amounts of lossless compression to large amounts of lossy compression. This is a common standard on the World Wide Web, but the data loss generated in its compression makes it undesirable for movie viewers.

Resolution Guide to Quality Prints
The higher number of megapixels a camera has, the more detail an image will retain when enlarged and viewed

1 to 2 Megapixels
Cameras with this resolution range are sufficient for sending photos electronically via email, but are not ideal for printing or for movie files. Most camera phones, PC camcorders, and PC cameras have a resolution in the 1 to 2 megapixel range.

3 to 4 Megapixels
Cameras with this resolution range are good for printing and retouching the standard 4x6 inch views in media players

5 to 6 Megapixels
Cameras with this resolution range produce professional results when enlarging photos up to an 8x10 inch format and can be good on 14 inch video monitors

7+ Megapixels
Cameras with a resolution range of at least 7 megapixels promise superior quality and detail when printing or enlarging photos beyond the 11x14 inch format and on video format could be seen as best quality

file size is important as well as format
By simply looking at the file size, you will quickly learn to be an expert judge on quality. A picture of 100kb (kilobytes) or less is most probably too low-resolution for good quality digital printing. Once you get to a minimum size of 400kb, you are working with a more useful resolution for an 8x10 inch print. use editing software to get the professional look for the movie.such as final cut pro, movie maker etc

Photo labs and editing technician can easily handle digital files directly from your memory card. Take your digital camera, a homemade CD, or your camera's memory card along for professional quality digital photography printing or convert them as DVD or other format as you require.

Voice over Internet Protocol (VoIP) is one obvious platform that experiences the technological morphology. No longer must VoIP users be confined to their own voices while talking to families, discussing business matters or conducting long-distance interviews. Voice changers could conveniently morph natural voices across many ranges, like age, gender, or both.

Another information front that epitomizes this new morphology concept is the personal absorption of multimedia clips. Technically said, DVD morpher software offers an ability to morph music and movies, adding special audio and video effects to the tracks or removing unwanted scenes from favorite videos.

 you could use your webcam image, without even a webcam while live chatting. People are now able to add animated texts and pictures to the webcam image, or fake it with another face accompanied by real gestures and expressions, which is made possible by something that might be called webcam morpher.
