There are some pictures you plan far ahead of time. Some can take years before you get what you wanted. An example was one I got of Castle Mtn few years back during the winter. The idea for that one came during the summer as I was walking along a creek which had calm water. Most winters the creek did not completely freeze over, so I thought the place would be great to get a picture of the Castle Mtn one winter. When everything would be covered with snow except for the small pockets of open water. I tried a few times to get the picture, the light was not right and or the clouds were in the wrong position. After several attempts I got the image and I made sure I got several variations. The list will never be complete for these type of images, always adding more. I like the challenge and I like raising my standards for the image I want.
But I also like the challenge when I see something front of me and I have to hurry to get the picture before the light or the subject change. That was the case yesterday as I saw the moon rising next to Mount Rundle while shovelling snow at home. I saw, ran inside, grabbed the camera and quickly got the picture.
