The Daily Snap – June 17

This snapshot of my camera set-up shows how I am doing long exposures with my Canon EOS-1ds Mark III. First I set up my composition with no filters in place. I used my 24mm TS-E lens for a wide-angle view. I manually focused 1/3rd of the way into the scene, and then tilted the lens into the plane of cracked earth until both the foreground and the background looked sharp (I used Live View to check sharpness). I then put my lens at f10. I normally use some aperture between f 8 and f11 with my 24mm lens (these are the sharpest apertures with this lens). Then I placed a Singh-Ray LB Polarizer into the first slot of the Cokin Z-pro filter holder. Next I placed a two-stop hard edge Singh-Ray grad in the furthest slot on the Z-Pro holder to hold back exposure in the sky. I took a meter reading and got an exposure of 1/8th of a second. I then placed the Lee “Big Stopper” (10 stop ND filter) into the middle slot of the Cokin holder and wrapped a black velvet cloth over the filters and filter holder – see shot above. This cloth prevents stray light from bouncing around between the filters which would cause the image to go ‘milky’ during long exposure. Finally I set my camera to bulb and made an exposure of 2 minutes at f10 (10 stops longer than the 1-8th second exposure) using a cable release. The resulting photo of Abraham Lake (in spring) looks like this:
