This video shows a quite stunning demonstration of available light vs. soft flash. In this demonstration, I set the lens to f1.8. By shooting with an aperture wide open like this, I’m able to achieve a look that is identical to shooting in low lighting with the lens wide open.
Not a lot of people venture this wide open in flash photography, and that’s a huge missed opportunity for creativity. Watch this video, and you’ll see a comparison between available light and a very soft flash puff.
One thing great about using flash for your indoor images is that the main color temperature never changes. this dramatically increases your workflow in post.
