Sculpt­ing shapes with light

ImagineFX - - In depth chaotic Art -

Now that I have my light source, I keep it in mind for the rest of the im­age. The key trick here is to ren­der the im­age as if you were a com­puter: vi­su­alise the light source in your head in 3D, and fig­ure out where it hits. Of course, you can cheat a bit to add some high­lights here and there, even if it’s not al­ways 100 per cent real­is­tic. Here, I add some high­lights on the struc­ture in the back­ground to de­fine the struc­ture, and also at the bot­tom left so that the lit­tle spikes will stand out more. Be sure to add vol­ume to ob­jects by keep­ing their shape in mind and think­ing how light hits them. In ad­di­tion, try lim­it­ing the main lit area to a spec­i­fied area of in­ter­est.
