October Programming - Forest Bathing
Guided Forest Bathing + Nature Therapy Walk RSVP HERE
Join Jess Thenhaus, Certified Forest & Nature Therapy Guide and founder of Urban Forest Therapy, for a guided Forest Bathing + Nature Therapy experience at Emmenegger Nature Park in Kirkwood, Missouri.
Inspired by Shinrin-yoku, the Japanese practice of Forest Bathing, this gentle, immersive experience invites you to slow down, open your senses and experience the natural world in a different way. Jess will guide you through a series of open-ended sensory invitations, with time to explore at your own pace and optional opportunities to gather and share.
This is not a strenuous hike. We’ll move leisurely, cover one mile or less, and spend plenty of time simply noticing and being outside. No experience with mindfulness or meditation is needed, and the walk is suitable for a range of fitness levels.

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.
