I built KeychainViewers.com as a new better, faster shopping cart when my shopping cart at ColorSlide.com became too confusing.
I take my client’s digital images and I print them to a device called a film recorder. It has a built-in 35mm film camera and it uses a small TV screen as the light source. Your image is printed with 4 thousand lines of resolution on that small piece of 35mm film, which results in very sharp slides.
Then I cut the film and place it inside these retro keychain viewers and mail them all over the country.
