Nice one, the texture of the parking lot shows up well in this very harsh lighting. I'd like to see more urban landscapes in colour if you have them. How are you achieveing a neutral colour balance with long exposure times?
Mathew, the length of the exposure is not the problem, but the temp of the manmade light. Generally speaking I bracket toward over exposure the extra density allows for more room when fixing will colour that is way off.
I'll post more later I've reached my daily allotment for now
