In some previous posts I showed the results of experimenting with focus stacking. In those posts, I would combine one of the individual shots with the finished effort to show how shallow the depth of field could be on individual shots and how deep the focus was on the final image. I was pondering whether this was an effective way of communicating the concept to someone when it occurred to me that animation might be a better way. I created a new stack of images for a different subject but this time I used Photoshop to animate the movement of the point of focus through the shot and then show the final image. This can then be an animated GIF. I wonder, does this provide a better demonstration?
The jets approaching SFO have their gear down long before they reach Coyote Point. However, if you look into the distance, you can see them lower the gear somewhere around the San Mateo Bridge. The A380 has a gear sequence that involves the outer gear coming down first followed by the body gear. I figured I would shoot at long range and then animate the sequence. Heat haze was not great but I think it shows the way things work. Maybe in the winter I will try this again and see if I can get a cleaner image.
