A brief history of computer graphics, from the earliest text character images from non-graphic mainframe computers to the latest photographic quality images from high resolution personal computers.
The main reason for the many computer graphics file formats is their different methods of compression. Find out how the file formats compare and how to choose the right format for the best results.
It's important that all websites optimize their images – Google does, and so should you! This section details how to optimize web images so that they reproduce well, take minimal space and load as quickly as possible.
The process of scanning graphic images has many pitfalls. Resolution? Color depth? OCR? This section will demystify some of the complexities of scanning and help you produce better scans without creating huge, unworkable files.
Retouching is a technical term that refers to the process of editing an image, usually by computer. This can include anything from removing specks and blemishes, fixing damage, adjusting colours, merging images, or total edits. See some examples of my retouching plus a simple tutorial.
This is a collection of various graphics that were particularly complex to produce, complete with explanations of the steps used in their creation. One example is my "World Zoom", which took over a week to create yet runs for just over 15 seconds.
There are some age old optical illusions that are especially effective as computer images because of the bright contrasts displayable on screen. Take a look at some that I've collected and/or re-drawn.
In the early days of digital cameras, family and friends often asked my advice about this emerging technology. Here's some now-obsolete technical info that you may nonetheless find interesting.
In 2015, Google released a new, simplified logo. I wondered if it was possible to create a reasonably faithful version of this logo in SVG format in only 305 bytes.
