Taking care of and properly maintaining your media is essential to prolonging its quality and usefulness.

  • Problems will occur, with both data and the equipment, if kept at temperatures over 100 or below 20 degrees. 65 degrees is ideal for storage.  Don’t use media and equipment immediately after quick temperature changes (going from cold outside to warm indoors). Avoid those temperature changes when possible.
  • When storing, use the safety switch – protect yourself from recording over important material.
  • When storing media and equipment, make sure to protect from dust, dirt, and damage.
  • Always label and identify recordings.

Some Suggestions in Media Care and RecordingAdditionally, when recording, there are several other things to consider.

  • Record at a standard speed to ensure better sound and video quality.
  • Use the highest data transfer rate – you will lose recording time, but gain quality.
  • Always check how much time and memory you have left on a tape and how much battery is left for the camera.
  • At the end of every recording, review your tape for quality.
  • Always take your media out of the camera to make sure it’s not taped over, and label it clearly.

The Types of TVs

As technology has improved, we have many different choices in how we view our videos.

The first is the old fashioned way – the “tube” TV, or the CRT (cathode ray tube). This is the big, bulky TV that paved the way for television sets in general back in the 1930s. Although the technology is older, it still projects a quality image, by projecting an electron beam through a vacuum tube to the phosphorus coated screen.

One of the newer technologies is the LCD (liquid crystal diode) screen. These are flat-screen TVs that send electric current through a liquid crystal solution, forming a quality image. They are fairly energy efficient and seem to be replacing a lot of the CRT style TVs, but are still quite expensive.

Plasma TVs are another style of high-quality flat screen TV. These tend to use more power than LCD screens, and don’t last as long, but they do offer a sharp picture with brilliant colors and deep blacks.

More Monitor Differences

Another thing to think about is not only the type of TVs that are on the market and how they display picture, but also the basic difference between television receivers and picture monitors – both used in the production industry.

Television receivers are designed to display broadcast programs and sound. They include a tuner, allowing them to receive television programming. Picture monitors were designed to provided higher quality images and don’t include the technology to receive off-air broadcasting. They may or may not include audio technology, but their higher quality picture quality usually makes them more expensive.

The Science of Seeing

The way we see color doesn’t change depending on what we are viewing.  Color is picked up by our eyes through color selective “cones”, discerning colors from the color spectrum: red and orange, green and yellow, blue and violet. Most colored surfaces reflect a mixture of three primary colors – red, green and blue – in some proportions. The green of trees is actually a mixture of different shades of light and green throughout.

Cameras see color slightly differently. They use the same basic system as the eye, but light sensors in the camera can only respond to the intensity of light and cannot directly identify colors. When a color video camera is recording, the image and color passes through a sensor and over a light filter, signaling which colors you should see. When you watch these scenes and images, your eyes see color by analyzing its parts.
