Back in the old days the canonical example of an over-used effect was the HTML
<blink> tag. One of the top candidates today has to be the ‘glow effect’. Having said that, if used judisciously, it can be a very effective effect. So, when should you use it and how can you implement it?
When to Use a Glow
The short answer to this is rarely. There are some very specific instances when an obvious, in your face glow is appropriate. Scenes that naturally include a source of illumination are the obvious use case. Examples include space scenes, aurorae, fires and flames, bio-luminescence, glass objects, neon signs, sunlight through windows, water and ice.
More common, and often over-done, are glow effects in logos and lettering.
Perhaps the most common ‘correct’ usage would be in user interface elements such as glowing buttons etc.
Finally, glows are often employed to produce more abstract images.
