I saw this pic today that was stunning and back lit. I just couldn't believe it. For the life of me I can't solve this mystery. If i shot that, the foreground woulda been totally black. I checked out the description the person put on and they said they used "5 stop graduated ND filter" I'm posting the pic below. Now does that filter have anything to do with what i'm talking? If it does can u please explain how it works Basically how can someone shoot a pic like this? The only thing I know is to use Fill Flash. but I don't think they used that here judging by the distances. Please help
