Lily

Elizabeth: Looks like this is your first Flora post so welcome to the finest Flora gallery on the planet and for helping it remain so. Beautiful subject and overall a solid capture. The only thing that gives me a little pause is your POF. I find the near anthers that are a bit OOF a little distracting. When faced with this kind of subject that has a bit of depth to it I practically wear out my DOF preview, especially if I'm trying to get it with a single capture. It can be tough balancing the desire for full sharpness of the subject while maintaining a pleasingly blurred BG. Great to have you aboard and looking forward to more. >=))>

A beautiful plant, but not American Columbine. This is a hybrid Spider lily of some sort. There are many hybrid varieties. Google Spider Lily. You will find some close to this. 

Welcome to Flora, Elizabeth! This is a very tough plant to get full focus on. You have done a good job except for the near OOF anthers. I have worked Spider Lilies a few times before. The best way, IMO, is to close down to about F16 to F22 and make sure there is no background or use a setup background. I have tried stacking images, but there are too many artifacts created by crossing petals and anthers.

Nice comp and colors.  I would like to see more DOF to get all the anthers in focus.  But this is still a nice image of a cool looking plant.

A very snazzy looking lily, Elizabeth.  I do kind of wish for more dof, but you'd really be pushing the shutter speed unless you had a tripod and no breeze.  Did you take any shots from a little lower with the stone wall as the bg?  I kind of like the looks of the part of it I can see.

There have been some very helpful comments already, Elizabeth.  I will just add that I think the light on the flowers as seen against the dark background works really well.  Hope to see more from you !!

Thank you all for the comments and suggestions.  This is my best image of the lily.  It was hand held and at a time when I knew even less about the camera than I do now.  And boy, do I have a lot more to learn.  I am now playing with F-numbers, there is so much to consider with each picture.
