Flowers and plants can be more challenging then one would expect (at least for me). Primarily, the photographer must be concerned with depth of field, distance to the subject, lighting/shadows, etc. Once you get those parameters set, usually the wind starts blowing (aka: Murphy’s Law). Even the slightest breeze can ruin a shot when focus bracketing. Of course, that’s why it feels so good when you get it right and get that shot!
