A couple of days ago my brother in law (using adobe products) and me tried to emulate the Masashi Wakui look following the excellent analysis from the post here in the forum. We got relatively close, but couldn’t get things to glow and there was still less color in our pictures.
Shortly after that I had the idea to use the residual of a wavelet decomposition to color areas. The coloring part worked nicely as expected but using the wavelet decompose brought another surprise that I hadn’t expected, “flooding” lights using a higher decomposition layer. Tried it on a picture from Tokyo as I had been there a couple of years ago and, sorry if I sound arrogant, but I am totally stoked about the result.
Tried it on a daytime scene with colored lights and it also works nicely, though the effect is different:
Tried it on another country, and believe it or not, it also worked!
I am really happy as things turned out and there are more possibilities to this technique.
