For this photo, I placed the lens next to one of the flowers and focused on the ground. Then I set the lens to manual focus so focus would be locked on that distance. The ISO was 800- selected this high because it was windy and the flowers were moving, so I wanted not only a lot of depth of field, but also a faster shutter speed. F stop was maxed out at f16. That resulted in a shutter shutter speed of 1/1600 second. Rather than using a remote shutter, I set the camera to fire using the built-in intervalometer. I tripped the shutter to start the intervalometer and then set the camera in the dirt facing up to capture the blooms in the sun, which was peeking out from the clouds. I tried several different flower groupings to find the best composition. Shadows were opened up in Adobe Camera Raw.
Please remember that when taking a photo like this, be careful not to hurt the flowers, and be sure to follow all posted rules of the location you are visiting.
