High ISO – Who needs it if you got a big flash?

As they say, it’s not the size of your flashgun that counts but the sensitivity of your sensor (ok .. they don’t say that but they may as well).

The photograph below was made with the flash at ISO 160. As you can see, the flash fired enough to properly expose the objects on the table. When shooting with such low ISO the flashgun assumes the role of Key Light and overwhelms the festivities of ambient lights – which was not what I wanted this image to convey.

The frame below was created with the same Aperture and Shutter Speed settings but the ISO was increased to 1250. At this level of sensitivity the flash functions merely as a fill in and the camera is able to absorb most of the ambient light. Can you spot the difference?
