Summicron 50/2 : Natural Light portrait

At a pals house there was a ray of sunlight from the setting sun that went through 2 doors and a hallway and had this finely defined edge, so I got a pal of mine to stand in it. he was reluctant to be photographed, and wanted to take a shot of me.

So I asked him to stand there so I could get the camera setup, I took this shot , and handed the camera to him for 1 other shot. By then, the light was gone......

 I took 2 of my hand to get the exposure correct and then took this one shot , we took a total of only 4 !  I converted this one to B+W to see if it looked better ?
