Last time I mentioned about using fog in photos. I needed a month to make this micro-tutorial about light. Photographers should know that you should get the “best looking” pictures in a one hour window after sunrise or before sunset. This should give a huge contrast between the shadows and lit areas. But the one hour rule is good for portraits taken on a flat field near the equator far away from the city. When it comes to a crowded urban area in Poland during winter you could get 15-minutes-or-less window for your best shot.
I was amazed by the shadow-light play that had place somewhere between 4:25 and 4:40 near a railroad station in Warsaw – Ochota but – as I said – it took me almost a month to get the timing and weather right for some shots.
