Any FWIW, You can't have a 'real life' photo. Doesn't work anything like the human eye(s). With your background RR, you should know that!
So is long exposure photography cheating too?
....No offence or accusation of cheating etc was intended. I just genuinely wondered how well kept and clean your engine bay was pre Photoshop enhancement and manipulation and now I remain in great admiration of your work, both in what you mods you have done and your photography.
