Hi, I’m Geoff. You may know me as Foomandoonian.
I know how to index a GIF and when to use a JPEG or PNG. I know what a process colour is and when to use spot colours. I know what a Bézier spline is and can use one. I know what a UV map is, and when a procedural texture might be better. I know what blending modes are, and the difference between ‘lighten’ and ‘screen’. Aspect ratios and resolutions do not confuse me. I know what an f-stop is and how to make good use of depth of field. I kern. I know why style sheets cascade. I know what a canonical URL is and can tell you everything you really need to know about SEO in twenty minutes. I can produce excellent compositions and usually tell you why. I know the meaning of far too many acronyms.
I learned all these things for fun. Do you want to know more?
