This image from Frank Doorhof was shot using just one speedlight modified with the Rogue FlashBender 2 XL Pro and it demonstrates how you can create beautiful, soft light on your model without loosing the “crispness”.
"The cool thing about the FlashBender XL is that you can literally just “mold” the light anyway you want. It’s without a doubt my favorite speedlight modifier. It’s so versatile it just keeps challenging me to push myself forward into more creative uses.”
