Photoshop version 1 was release by Adobe in 1990. Thomas and John Knoll (Photoshop’s developers) began development on Photoshop in 1987. The program was intended from the start as a tool for manipulating images that were digitized by a scanner, which was rare and expensive device in olden days. This is what version 1.0 look like. It is very primitive program and doesn’t have a quarter of functionality compare with the Photoshop version 9.0 known as CS2.

The most obvious thing lacking was layer support, which was introduced in version 3.0 sometime in 1993. Photoshop 1.0 included primitive selection tools and basic image filters/adjustments.

In this picture you can see Photoshop’s whopping two palettes, which let the user pick a brush, color, and pattern.

This is Photoshop’s preferences dialog box, believe it or not. You could set up separation, interpolation method, and column size, among others.

There was even (very primitive) type support in PS1.0, as you can see here. You could set font leading, spacing, style, and alignment — and you had to write your text into the type dialog, after which it was placed into your image.
