I found this image that has a similar color grading to Liam Wong's Tokyo Nights series though it isn't actually his, and I'm curious as to how the effect may have been achieved.
It's obvious the image has gone through a heck of a lot of post processing as I'm sure the original photo was not lit originally using pink and blue light.
I'm thinking they could of achieved this effect a few different ways possibly by playing around with the color mixer, color balances, gradient maps, painting in colour and fiddling around with blend modes? What do you think? How is it done?
