SUMMIT COUNTY … Still fascinated by the light, textures and flows in the freezing rivers of early winter. It’s a challenging photography environment; wet, chilly and not much level ground for a tripod, but the resulting images are rewarding to me, full of life and vibrant color. You have to choose the right time of day. If it’s too bright, you can’t use long exposures to smooth out the water, at least not without a neutral density filter. If it’s too dark, the images end up murky. But when you get it just right, it can be pure magic.
