One of the questions I get the most is how I take daytime long exposure photos. I made a video so you can see exactly what I do, how I look at the clouds and light. Here is a another blog post I made covering this exact topic along with lots of sample photos.
Here is a long exposure I did almost a year ago, omg where does time go?? I remember this particular morning, one of my friends picked me up and we headed out bright and early. We stopped at this awesome pier to do some long exposures with some filters. It turned out great even though it was very gloomy out this morning.
We stuck around until it was really bright and kept on shooting until we got really really hungry.
