Before we look at some Photoshop fun bits, a little piece of useful information.
Plenty of jerks steal lots of information from this page and the whole site. They lift complete pages of text and photographs. These morons are too useless to produce anything themselves. Copyright theft is also a criminal offence.
To continue . . .
What is a pixel and how big is it?
A pixel is as big as you want it to be.
Photoshop images are made up of digital information in the form of pixels. Pixels have no inherent size because their size will depend on the resolution of the image. With two files of the same dimensions, a file with a resolution of 150 pixels per inch will have larger pixels than a file of 300 pixels per inch.
In image-editing programmes images are known as bitmap images, also referred to as raster images. Drawing programmes, such as Illustrator and Freehand, create vector graphics mathematically. When an image is resized, a new mathematical calculation is made, which maintains the quality of the image.
Vector programmes are best suited for strong graphics and text where sharp edges are required.
Where does the word pixel come from? A: It's an abbreviation of the expression picture element.
Hidden splash screens
A splash screen is like the title page of a programme.
To see the one for Photoshop, go to Help > About Photoshop on a PC, or with a Mac go to the Apple icon > About Photoshop.
Each edition also has its own hidden splash screen, known as Easter Eggs, used for the Beta test version. On a PC, hold Control the go to Help > About Photoshop.
On a Mac, hold Command and go to Apple > About Photoshop.
The Photoshop fun with these wacky screens started with Version 1 and those shown here are for Photoshop from version 4 up to the present version.
With Version 4 on a Mac, you can hold Alt and click on the cat's nose. The cat opens its mouth and burps.
Version 5 was code-named 'Strange Cargo'. Type BURP, the crate opens and the cat looks out and burps. The cat's name is among the lines of text and that does something as well. Marc Pawlinger's face is within the flare; he is one of Photoshop's developers.
Version 7 still has the electric cat.
Version 8 has its own screen and mousing over reveals a couple of extra images.
The Image Ready programme had its own hidden splash screens, complete with quacking ducks. Explore with the Control/Command and Alt keys. And there is a duck within the logo.
Personal messages abound
At the bottom of each image is a small band of white; click on it before the credits start scrolling. Let all the credits scroll through and as the credits roll starts again, personal messages (Adobe Transient Witticisms) appear on this band of white.
Plums! Chicks dig it.
Besides, I have freckles.
The streets are cold in Q3, ya know.
Chaos, panic and disorder - my work here is done.
The efficiency of the coconut wireless is not to be underestimated.
They go on forever and I've not yet survived to the end.
The Photoshop developers are just a bunch of old hippies.
The hidden splash screen in CS3 is about the plainest there has been.
The splash screen image can be copied and opened in Photoshop.
Open Levels and drag the Highlight slider to the left to reveal that cat again, inside the pill.
Drag it completely to the left and there are paw prints behind the text.
Move the Shadow slider to the right and an image of Bruce Fraser appears.
Bruce played an important role in digital imaging and software development and died in 2006.
For the Witticisms in CS3, click just above the credits before they start to scroll.
And now the hidden splash screen in CS4.
The cat makes a return in CS5, and the white rabbit with its curious implications.
The developers continue the Photoshop fun in CS6 and the hidden screen is quite restrained and cool.
Once again, hold Control/Command and go to Apple > About Photoshop.
With a Photoshop panel open, such as Layers or Paths, click on the arrow in the top right corner. Hold Alt as you select Panel Options or Palette Options depending on your version of Photoshop. Merlin was the code name for Photoshop 2.
No more 'Merlin' in CS6.
Who started Photoshop and When?
In 1987, Thomas Knoll was a post-graduate student at the University of Michigan. While preparing a thesis, he wrote a computer programme to display greyscale images. His brother John became interested here. At the time, he was working on visual effects for George Lucas films and the two brothers began collaborating on the programme.
Thomas expanded the code to display colour images and installed it on the first of the colour Macs, the Macintosh II. The new computer was sent to John and together they developed new file formats and more processing facilities. Around this time, they named the new programme Photoshop.
Thomas developed new functions like selections, Levels and Hue and Saturation, while John set about finding a market in Silicon Valley.
A short-term deal was made with Barneyscan, a scanner manufacturer, who released a version of the program as Barneyscan XP with their scanners.
Following a demo to Adobe, the parties made a deal in September 1988. It involved a licence to distribute and the Knoll brothers were on a royalty.
Thomas continued developing the programme's code, while John worked on plug-ins. With input from a few Adobe employees, Photoshop 1.0 was released in February 1990.
Thomas Knoll still works on Photoshop development, particularly on Camera Raw, and his name is first in the list of credits.
No more typing
The typewriter was first invented in 1714, but the first practical machine was made in 1843. The word 'typing' comes from then and is part of history.
The modern word for using a computer keyboard is pidifing or to pidif.
It's an acronym of Positive Interface with Digital Input Facility.
A few of those developers must have a few rather slack moments.
In some earlier versions, choose the Type tool from the toolbox.
Click on the Panels button in the Options bar to bring up the Character panel.
Pidif in a font name, such as Verdana and then put in the names francis or anthony; take no notice of the beeps.
Click on the Panel symbol again. The image is not the same in all versions.
There is an Easter Egg on this page too.
No keys required, just the mouse. It's all part of the Photoshop fun.
