Whitewater and a 10 Stop ND Filter

Borrowed a 10 stop ND filter from a buddy for the weekend to shoot the whitewater of the South Platte River in Eleven Mile Canyon again. Set out early in hopes of finding a bounty of wildlife in the canyon before all the people arrived, but came up empty with that effort 🙁 The plan was to drive all the way to the end of the canyon in search of wildlife and then try out the ND on the way back down.

On the way up the canyon I scouted out a few good spots where I thought an ND would work well and hit each one along the return trip. I will say this, using a 10 stop requires a lot of concentration! Fortunately I downloaded a neat little app for my phone the night before called simply “Exposure Calculator”.  To use it I just set my camera to A mode at f8 and ISO 100 to get an exposure reading  and plugged that info into the app as the  base exposure. Then for the new exposure I plugged in the same data and selected 10 as the ND factor and wala, the app gives me my new shutter speed 🙂

I forgot my cable release so in order to successfully execute a long exposure I set my drive mode to two second timer, camera to maunal exposure mode and lens to manual focus at the same focal length and focus as the shot prior to installing the 10 stop. I also switched over to live view mode to lock up the mirror and then took the shots. Playback showed that I indeed got the correct exposure and I could see that the water was smoothed out as expected 🙂

Satisfied that I had captured the scene,  I returned the camera to all the normal modes and continued down the river. Then of course I

repeated this entire process at each location, getting both motion blur and regular images of each spot. Very time consuming and the big dog didn’t appreciate all the standing around the tripod one bit 🙁 Don’t think I would have the patience to do this all the time like I see some photographers on YouTube doing. But I do really like these two images and may actually get myself a 10 stop someday!

Of course these images and more are available on my website for purchase as wall art on glossy metal and acrylic sheets, stretched canvas and traditional framing and matting.  Tons of cool gift, household and tech items are also available with a picture, including, apparel, coffee mugs, phone battery chargers, phone cases,  blankets and more!
