One of the most valuable things that I have done is to keep a photography journal. Here I write down when and where I went and what the weather was like i.e. 4-6 am, 72°; very windy; Heald Street apple orchard or 7:45-9pm 96°humid, very foggy on the Squannacook downstream from the grist mill in Townsend Harbor. Then I jot down what I I photographed like what flowers were in bloom, any animals that were around; was it a successful shoot.
If you are photographing a body of water, does it have significantly different water levels over the course of the year, record those as well? This can have a major impact on the water flow like waterfalls and the size and width of a brook or river.
Later if you are going to a certain location, you can go back and see what you successfully photographed and what time of day was good. Speaking of the time you may want to take into consideration how close to sunrise or sunset you were there. This is because the time alone can throw things off. If you decided to go to a certain place where you had been at 8pm in the middle of the summer, but now it was the autumn; it would be pitch dark in the fall. Think reasonably.
In your journal you may find that certain places tend to be windy or early morning in the fall by a specific pond has that touch of fog to give your photos that special atmosphere you like..
Keeping your journal for your local areas pays off big time in the long run. Whenever you are thinking about shooting pictures in a certain spot where you have taken notes before, you can go to your journal and see what worked best. This way you cut down on your time experimenting with various areas and can focus on the places that worked best for you before.
Good luck and see you on location…
