It snowed last night and at around noon today the sun was coming through a thin layer of clouds—perfect for shooting food with available light.
That's the view out the window and that's my setup for this photo. I did this just to talk about using available light, white fill cards and also I just wanted to take a photo of the cool pewter antique dish I found a couple of days ago.
These two photos were both shot at ISO 100, F5.6, a 6th of a sec. shutter speed on a tripod. The first is just window light and the second has a white fill card placed to the right bouncing the light back filling in the shadows in front. You can see a big difference in the single clove's exposure. I only used one board here but you could use 2 in front to fill in even more shadows.
Then I turned the garlic toward the light, moved the camera so that the light was now coming from behind it. First shot is just with window light, second one, I used the fill card to bounce the light back (you can see where the card is). Less of a difference here. Front lighting is flatter and not as dramatic.
So when there's a blanket of snow outside—open a window and think of it as your big soft box studio light. Grab some white boards and go play.
