Three really nice ones. The first two are some of your BEST ...
These aren't pictures of flowers, these are using flowers to create kaleidoscopic art ... smokin' hot style, it looks like you're getting your technicals dialed in.
Jim,
About the only thing that I'd do would be to ... maybe ... lighten up the center shadows a touch to balance them in with the brilliant backlighting. Probably not much, just enough to kinda emulate some fill lighting. I think it would likely be to hard to control actually fill lighting to balance with your wonderful backlighting exposure.
I've been kinda watching what you've been trying to do ... and these pretty much look like you "nailed it", with previous ones I could see you were struggling to get what you wanted.
These are Suh-Weeeeet ... so diggin' the kaleidoscope styling.
Congrats on the hard work and diligent effort to get what you had envisioned to where we could see it too.
Kent, thanks for the comments. Trying to control the lighting is obviously a big issue. It is especially difficult to balance the front lighting and back lighting. Typically the front lighting is ambient and the back lighting is a flash. I have been shooting at the local arborteum and greenhouses so I cannot use a tripod for the camera or support for the flash. That means I am usually hunched over with my left hand trying to position the flash and I am rocking back and forth to hit focus and shooting with my right hand. Needless to say with the flash going off in broad daylight I am noticed and cannot get away with even one of my feet slightly in the flower bed. I think I need to start buying some flowers and shooting in a more controlled environment. Getting out of the wind would help but I really need a tripod and better control of lighting. Trying to get the lighting right by checking the camera LCD is also difficult. I really need to check results on a computer monitor and then fine tune.
