Let's break down the anatomy of mood boards.
When thinking of your mood board, consider the location or locations you're thinking to take your photographs. This helps you and your photographer when scouting areas that have similar looks and feels of your described locations.
It's not always necessary, but adding a chosen texture or items to your mood board helps give a bigger picture of the type of session you're aiming for. This can be an image of pumpkins for the falls season, the texture of water crashing on rocks for an beach sessionm or simply texture of comfy pillows if you're planning for an in-home session lounging on the couch.
This is the part most people preparing for session have the hardest time with especially when planning for a family session. When thinking of outfits, you want to consider a number of things: weather of those locations, purpose of session (holiday portraits are usually festive colors like burgundy reds, bold greens, and khakis, for example)
Just as long as you're not too matchy-matchy (think 90's boy bands with all the matching outfits.. you don't want that life.
Lastly, the emotion you want to emulate in your overall session should be shown in your mood board to help your photographer understand the emotions you're going for. It helps if you've chosen a photographer that is well-versed in pulling the emotions out in their subjects. Do you want your session to be filled with joy, laughs and happy family vibes? Great! Add images of this emotion in your mood board.
