Laura, and the others, thanks so much for your comments. Re: lighting- very technical and complex here. The flowers were in a vase, on our kitchen table, with the blank (black) screen of my laptop for a background. The only light was coming through the window, behind the flowers and whatever other room light there was. Was really trying out different long exposure settings. I did use a tripod and remote shutter control. Pretty low tech, actually. Thanks again. Happy spring!
