When we arrive at the put-in location, we'll get every paddler outfitted with a life jacket. Next, our river guides will provide a safety talk and paddling demonstration before we load into the boats and begin our paddle. Our adventure will start by paddling along the Missouri River to an uninhabited island.

This class is designed for photographers with beginner to intermediate experience who want to take more intentional, impactful photos.

Bring any camera you'd like help with, including your smartphone, DSLR, mirrorless camera, or point-and-shoot. We'll cover camera settings, practical shooting techniques, and tips for getting the most out of the equipment you already own.

During the class, Kim will share examples on the projector, break down how each image was created, and explain the settings, composition, and techniques used to achieve the final result. Then we'll head outside for hands-on practice and apply what we've learned in real-world situations (weather permitting!)

Topics we'll cover include:

Camera settings and when to use them

Smartphone photography tips and tricks

Composition and framing techniques

How to make a scene stand out

Understanding light and how it affects your photos

Kim Dillion’s Bio:

Photography has been at the heart of Kim Dillon's career for 25 years. After studying both photography and graphic design in college, she began her career as a graphic designer and editorial photographer for Smith Mountain Laker Magazine in Virginia. It was there that she photographed her first garden, a project that sparked a new passion and became her speciality. 

For the past 15 years, Kim has specialized in photographing gardens, landscapes, and outdoor living spaces for landscape designers, gardeners, and publications including St. Louis Homes + Lifestyles magazine. She believes photography and design naturally go hand in hand, and she brings both disciplines to every project, creating images that are visually compelling and thoughtfully composed.

Kim enjoys sharing her knowledge with others, helping all skill levels learn to see light, composition, and beauty in the world around them.
