If a vertical slide contains information critical to your presentation, it is best to have slide copies made of the upper and lower portions that approximate, as much as possible, the television 3 x 4 aspect ratio. It is best to avoid extreme contrasts such as black and white clothing. The television system has difficulty showing details when there is a high contrast ratio between objects. The television system also has difficulty with tight or busy fabric patterns such as tweeds. They result in odd, moire patterns appearing in the video image.
Pastel colors are easy on the viewer's eye and convey a cool, relaxed image.
Clothing that contrasts with the background will provide separation, presenting you in a more complimentary setting that has visual depth and interest. Be cautious about wearing jewelry. It can sometimes create reflections that may cause disturbing flares in the video image. Also, a necklace or tie clasp can rub against a lavaliere microphone attached to your clothing creating a distracting noise in the audio. Contact the Video Center for assistance early in the developmental stage of your presentation.
