Thanks, Archibald.
In truth I wish I had used f/22; the fewer images I need to stack the better. I find it very difficult to get a seamless blend when you have elements that are overlapping (ie, flowers and grass), and both of them are moving between shots. If in one shot the flower is very sharp but the grass directly behind it is a little soft, and in the next shot the flower is slightly soft and the grass is very sharp, but they have moved compared to the first shot, it is very difficult to get that to look right. This is especially true for elements in the very near foreground when your lens is inches from them. There just isn't a lot of room to "fudge" like there is for elements in the midground. I did have to clean up the stack and it would have been easier if the flowers and grass that were overlapping each other were sharp in one shot.

Thanks for the explanation. I don't have experience with focus stacking landscapes, just macro. And I realize the situations are very different. Certainly motion in the scene would be an issue in landscapes. So your solution is to reduce the size of the stack, and that is done by stopping down. Very well executed.
