Plant photography tends to make us think of tightly focused close-up shots of blooming flowers. Close-ups with strong depth of field are perfect for creating bold, striking images -- but sometimes it's worth stepping back and admiring the big picture.
Don't focus on a single flower; focus on an entire field, or an interesting array of plants, or a jutting rock covered with moss. Shoot at an interesting angle. Maybe that means getting up close to a flower, but shooting with a deep depth of field to keep everything in the background in focus. Shoot from a low angle to balance plants against the sky. In the right location, the scale of a landscape photograph can be more dramatic than the usual tight shot.
When shooting a landscape photo with a wide-angle lens, everything from the ground to the sky will be in focus. Usually, however, plant photography requires a shallower depth of field; the next tip is about distinguishing a flower from its background.
