I do like the photos cal especially second photo but they do look to me …. becalmed. I would like to have some motion in the blades. That may not have been possible with the first as it was bright but the second was at 1/200 and you should have been able to get it to 1/60-1/30 range. Down there you should get some good motion blur on the blades and it could look like the storm was really blowing.

At the location of these towers, the wind was moderate. It should be noted that these turbines rotate at a constant speed regardless of wind velocity. Each turbine has an anemometer and wind vane that determine the wind direction and speed. The direction info is used to keep the turbine pointed into the wind. The speed info is use to change the pitch angle on the blades to maintain the constant rotation speed.

Thanks everyone for your comments. I was really surprised to get this much response

That is the unfortunate reality. Fortunately we get to work with photography! We can show what we may perceive, not just the reality of things.

The artist adds to the canvas until they stop with their version of reality. Digital photography is subtractive art. First we throw away 90 percent of reality then remove what is left bit by bit until we have only the reality we wish to show. Flickr is like fun. PPG is like work. A camera is a machine of light and time with the purpose of capturing a luminous moment. Like the eye it is a tool of the mind.
