Which lighting style was most difficult to create? Which gave you the best result ?
1: The most difficult Lighting style that was difficult to me was the Rembrandt Light because it took me some time to get the angle just right where there was a semi light triangle on my right (your Left) cheek. Plus I have glasses and I wanted to take a challenge.
2: I say the best result was from the short light because the light was perfect during the time of day for some light to come from the side while my ear in the frame is not lit from the light which is what was needed and I think it worked out.
