Tip 5: How to brighten people.
People are tricky, and sometimes your favorite moments can't be captured in the perfect lighting. I think bright, contrasty photos can be really flattering for skin tones and just generally make your photo look better small or far away (which is good for posting on Instagram).
In the photo above, I used brightness and contrast as well as my favorite Afterlight filter with a blue tint (Relic in the Original pack) to help correct our red skin tones caused by the sunset.
