This is my photo for the capture the sky challenge. Thanks Heidi

I found this to be a hard thing to do. When I tried to take photos of people with the sky in the background, the faces were dark unless I used a flash and when I added the flash, the sky disapeared! Great challenge Heidi, I will keep experimenting! Any tips are appreciated
