Control over the chemistry and film thickness (scale of hundreds of nanometers) allows for spectrum-specific sensor reception, including outside of the visible light range. Modern consumers respond with "ZOMG, better cell -phone cameras!?""
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
