The clouds were providing a very ominous background to the city skyline yesterday until the sun went down and then turned into quite a spectacular display of colors. I used a 2 Stop Graduated ND filter to balance the sky and a 3 Stop ND filter and allowing me to get an exposure time of 25 seconds. The long exposure time creates the smooth texture on the water which also helps to illustrate the movement of the river. Single Exposure – ISO 50 – f/22 – 25.0s – 28mm Canon EOS 5D MkII Body and Canon EF 28mm f/1.8 Lens. Photographed in Minneapolis, Minnesota on 7-3-2014 at 8:00...

I stopped by the Ford Lock and Dam right after another storm moved through the area, hoping to use the dramatic clouds as the backdrop for the rushing waterfall. I noticed that the locks were both closed, I have not been to this dam recently, but I was surprised to see them both closed. The photo of the St. Anthony Falls Lock and Dam I posted from yesterday shows the lock open with water rushing through it. I eventually wondered to St. Anthony again tonight and noticed that the lock was closed as well. This is a good sign for anyone effected by the recent flooding because it means that the river is returning to its normal volume. 3 Shot HDR with exposure times of 0.8s, 0.2s, 3.2s – ISO 50 – f/22 – 17mm Canon EOS 5D MkII Body and Canon EF 17-40 f/4L Lens + 2 stop ND filter.

Viewed from the Stone Arch Bridge in Minneapolis the Sunset over St. Anthony Falls was very interesting yesterday. By using the multiple shot HDR technique I was able to capture the details of the buildings and bridge, made difficult by the setting sun behind them. Also the details of the clouds and the bright sun were all preserved to create this dramatic view of the waterfall at sunset. 3 Shot HDR with exposure times of 1/200s, 1/800s, 1/50s – ISO 400 – f/16 – 40mm Canon EOS 5D MkII Body and Canon EF 17-40 f/4L Lens.

Looking towards Minneapolis and the Third Avenue Bridge over the Mississippi River at sunset. I started shooting long exposures of some of these scenes and I really liked the effect which it created on the water by smoothing out the waves and making the reflections very bright. It occurred to me that If i was to use Auto Exposure Bracketing (AEB) to make one image as normal, one image -2 EV to expose for the clouds and bright sky and one image at +2 EV to expose for the details of the buildings that they could all be merged together to create one image impossible to capture with normal methods. The name for this technique is called HDR or High Dynamic Range because it creates a much larger range of brighness than normal range between the dark shadows and bright sunlight. The +2 stops over exposed version has little detail in the sky but because it was a 6.0 second shot it has the beautifully smooth water reflecting the sunset. The -2 stops under exposed version has excellent detail in the sky and clouds but the bridge and buildings look like a silhouette they are so dark. Most DSLR cameras have an AEB feature (it could have a different name) which when switched on will make your camera shoot in groups of usually 3 photos (sometimes 5 or 7) but i think three is plenty. By using a tripod and shooting groups of three photos in rapid succession I was able to capture the exact same scene exposing once for the sky, once for the shadows and once for...
