What incredible finds can you make among dusty old slides from the 1970s?

35mm slides, also known as "reversal film," are called this because the image is placed on a transparent base.

Before being digitized, 35mm slides were traditionally viewed using a slide projector.

The resolution of a 35mm slide is roughly 4000x2600 pixels.

Kodachrome, a popular color slide film, was introduced by Eastman Kodak in 1935 and was widely used until the introduction of digital technology.

Slides from the 1970s might have a red tint due to the "bleach bypass" effect caused by the aging of the dye components.

110 slides, introduced in 1972, were available in two formats: one with a 2"x2" slide mount and a 13mm x 17mm transparency, and a smaller version with a 1"x1" slide mount and the same transparency size.

Digitizing 35mm slides can be done using flatbed scanners or dedicated film scanners.

Popular slide scanner brands include Epson, Kodak, and Reflecta.

Slide scanners can vary in resolution, with some offering up to 10,000 dpi.

The process of digitizing slides also helps to preserve the memories and enables easy sharing through social media and digital platforms.

Slide mounts are typically made of cardboard, plastic, or metal.

A single roll of 35mm film can hold between 12 and 36 exposures.

Before the 1970s, most slides were black-and-white.

Color technology became more popular during the '70s and '80s.

Some popular 35mm cameras from the 1970s include the Nikon F2, Canon FT QL, and Olympus OM-1.

The rise of digital cameras in the late 1990s and 2000s contributed significantly to the decline in popularity of 35mm slides.

Slide scanning software can help correct issues such as color shifting, dust, and scratches.

Compared to negatives, slides provide better color accuracy and dynamic range but can be more challenging to scan due to their transparent base.

The American National Standards Institute (ANSI) established guidelines for slide mount sizes.

Proper storage of 35mm slides can ensure longevity; it is recommended to store them in a cool, dark, and dry place with minimal exposure to air and light.

In 2004, the production of slide projectors ceased due to the increasing popularity of digital images.
