Photo-realistic icons can be handy when designing certain types of software products and Web services. While converting an image into icon is easy, creating a good-looking small-pixel-count icon from a high-resolution photograph is not.

Every application icon comes in a variety of sizes, making it time-consuming to create a single icon image. Icon making is a complex process, and although taking a photograph and converting it into an icon image may sound tempting, the results produced without following certain rules are disappointing at best.

Various Resolutions

Each icon image contains a number of icons sized from 16x16 to 256x256 pixels. When creating an XP icon manually, you have to remember about the different sizes, and take care of each resolution if you want a fully compatible icon image.

Different Color Depths

Translucent Icons

The True Color icons support semi-transparency with alpha mask, making the icons blend with their background to provide better visual experience to the user. Semi-transparency is a powerful tool for creating smooth, realistic icons with soft shadows and anti-aliased edges.

Icon File Format

Icon Resizing Issues

The smallest icons come in 16x16 and 32x32 pixels. While the small size makes it easier to hand-draw an icon, the same matter of size makes it difficult to create a usable icon image out of a photograph. Existing resizing methods fail miserably when it comes to sizes like these. In order to produce a good-looking XP icon, you have to use software that applies downsampling algorithms designed specifically for the small-size images.
