One thing people love are good memories, and pictures are a great way to savor good moments. Before everything became digital, slide viewers were the rave. In 1931, the slide viewer was born. People used slide viewers to view their pictures, usually during a gathering or special event. Due to the advances in technology, slide viewers are rarely used today.
How Do Slide Viewers Work?
Slide viewers use positive film instead of negative film like many cameras. Instead of prints, the positive film is put in a cardboard, rectangle frame to be viewed in the slide viewer. Once the film is placed in the slide viewer, the light in the viewer shines through the film, and projects on a surface, such as the wall or ceiling.
What Size Slide Will They Work With?
Most slide viewers use standard size slides which are 35mm positive film. Some slides use film that is 2 inches and 1/8. Most of the time, you can view slides that are over 50 years old, and keep special memories.
Types of Viewers
Yes, there are different types of viewers. Some viewers are more common than others. Common viewers include slide, overhead, and digital viewers. Viewers that are not as common as others include, cabled, wireless, AC powered, and battery powered. Each type of viewer has there benefits and disadvantages.
Slide viewers use a mechanical system that allows different slides to be changed when you’re ready.These viewers have a bright bulb that shines through square slides. A slide viewer magnifies and projects the images on small square slides.
Overhead viewers display information on transparencies, including notes and images. These viewers were used for the first time in 1940. Like the slide viewer, the overhead viewer contains a bright light. The bright light is housed in a large box with a lens over the top. The transparency is placed over the top of the lens. An overhead viewer has a long arm with a mirror that projects the transparent image onto a wall, ceiling, screen, or other surface.
Digital viewers are more up to date than overhead and slide viewers. These viewers, like overhead projectors, are used to display images, video, and data. Information can be shared through digital viewers through memory cards, computers, or electric devices. Digital viewers require bright bulbs to display information correctly. Because digital viewers can display a variety of media, they are more versatile than other viewers, and smaller than most viewers available.
Uncommon Slide Viewers
Cabled viewers are often favored over wireless viewers because the connection is more stable. Cabled viewers can be connected to many data sources. These viewers are less expensive than wireless viewers, the connection is not susceptible to an interference, and the viewer does not need to be wireless in order to operate.
