I bounced the light of a white wall in this picture lighting up side of the persons face and creating a shadow on the bottom right.I also like the flash you can see in the glasses.
This picture shadows in the picture again make the face pop out more and you can clearly see the detail of the face .The dark background also make the face stand out more.
I picked the image because when we bounced it off a yellow background we got a soft warm colour without using coloured gels. The shadows make the face more 3d making the image pop more.
