Photographer Jen Pollack Bianco told us that she uses flash for "fill-flash situations" when she wants "some additional light in the foreground of the photo to keep the contrast from being too dramatic."

Bianco, who won first place in the IPPAWARDS' "Travel" category, said the iPhone's flash is also "particularly useful for sunset shots" or for subjects "backlit by the sun."

Likewise, Brendan Ó Sé recommends only using flash when taking pictures in "very strong sunlight to fill in shadows."
