The deep blue sky and rays extending from the sun on the Blue Sky Visa Gift Card make a beautiful picture. The photographer’s technique made the sky a deeper shade of blue and made the rays of light spike out from it in exaggerated fashion. She achieved both effects by setting the f-stop higher, which makes a smaller opening in the lens to let light through. Often times the way we see things depends on how much we are willing to open our eyes. Your friends and family will love Blue Sky Visa Gift Cards.
