Outfits and color schemes: I feel that you and your family members should wear what you want to wear as long as it’s presentable. Bear in mind, toward the end of the session, I might ask you to place your ankles in the surf, which very often means even your romp is gonna get wet, too—all for a great photo.
Your hair: It gets windy on the beaches. One’s hair can easily wash over your face, not once, not twice, but consistently. So a headband, hair clips, scrunchy, anything to keep your hair out of your face might be the difference between a beautiful photo, and a photo sort of ruined by your hair partially or even mostly covering your face.
Your eyes: the eyes are the soul of the portrait. I know the sun is bright and squinty eyes come with that territory, especially if your eyes are sunlight sensitive. I have tricks to help you. But even when the sun is not in a face, all too often while I’m editing I find eyes that are consistently closed or just barely open. From where I’m taking the photos, I can’t always tell; So here’s the tip: Pay attention to your eyelids. If you sense they are cast downward, it means I’m getting eyes that are not open. Keeping your eyelids open might mean that you need to look above the camera lens, especially when I’m taking low angle shots.
Perspiration. A hot day on the beach. We might be walking around quite a bit to get new photo ops. The tip: Bring along a hand towel, or wipes, at least a handkerchief, especially if you know you’re likely to perspire.
Dress straps and bra straps: Often I see too many straps. If you to want to wear a bra under a dress that has straps, see if you can conceal the bra straps.
