Manipulation Techniques
Describe a variety of digital media techniques
Digital media can be manipulated or changed in many different ways. The methods used depend on the type of digital data and the purpose for which the data is needed.
Resizing- The process of altering the size of an image. The image proportion can be kept the same and the image won’t be distorted. Resizing can also be done to a computer window.
EG-Adjusting the size of a photograph so it fits on your document.
Cropping- The process of trimming a file to select only those parts that are required. The original content is not removed but the unwanted part is hidden so that it is not displayed.
EG-Cropping a family photograph so that only one person is visible.
Rendering- The process of covering or coating an item to create a whole item or 'image'.
EG-Rendering a sound creates an image of the sound; rendering an image covers the basic framework of the image with a covering of colour, texture or pattern.
Special Effects- Any draw tool that provides additional functionality to a digital media file.
EG-An image filled with a gradient fill.
Time Coding- Time code is set to the number of frames per second.
EG-24fps is used for 35 and 70mm film; 29.97 is used for most film editing
Data Sampling- Data sampling is when digital audio data is attained from real sounds. Samples or measurements are obtained from a microphone or digitising device to convert them into digital data.
EG-Recording music to your phone from a live concert.
Morphing- Short for metamorphosing, morphing refers to an animation technique in which one image is gradually turned into another. Many advanced animation programs support some type of morphing feature.
EG-When you are morphing two or three animals together to create a metamorphic animal.
Tweening- "Tween" is actually short for "in-between", and refers to the creation of successive frames of animation between key frames. In computer animation, the term is most commonly used for Flash's "shape tweening" and "motion tweening" processes, where the user can define two key frames and Flash will automatically create the in-between frames.
EG-Combining Two images together to create one succinct image. Like tow cars facing each other with a blend of backgrounds.
