A technique I happened upon a few years ago, and occasionally attempted with varying success. It's simply a matter of opening up your widest lens, setting the focus to manual and adjusting it to as close as possible, and then "dancing" around and through an object. Yes you will get funny looks from people as you move in, through, and around, your subject, in this case blooming flowers. The technique is improved with the use of extension tubes (which I don't own, but do covet) or using a tele-converter, I used a 1.4x for these images. Of the 400+ images I made that day I am pretty happy with this group. A couple I like very much and will add them to my website (still in the works...).
