Here's another image from my "on-black" series. This time a yellow columbine.
#CWLPhotographyTip - This image was taken at the local botanical garden; that is, the image was taken without cutting or removing the flower from it's place in the garden. To accomplish this type of image while outdoors, I carry a piece of black satin cloth measuring 80cm x 150cm (approx 2' x 3' ). I also carry a set of small, spring loaded "A-clamps".
Sometimes I place the cloth on the ground behind the plant or I'll clip the cloth to a nearby plant. If nothing is handy, I'll look for a stick or two and make a temporary "X" frame for the cloth or, if I have one, I'll use my walking stick.
Occasionally, if I know I'm going to be doing a group of flowers, I'll add a small, black umbrella to the kit. Most of the time we photographers like to shoot with the sun to our backs or off to the side. With the sun to our back, we can use the umbrella to cast the cloth into a dark shadow without casting the plant into shadow. The darker the black of the backdrop, the easier it will be to completely isolated the plant.
Once the background is in place and has been put into a dark shadow, if possible, I'll take a series of images at different f-stops and shutter speeds. When I process the images I'll load them into Lightroom first, then I'll load the selects into Photoshop; where I can completely remove the background and replace it with a true black. The darker the original black, the easier it is to get a nice, clean, crisp, "on-black".
Note: Why black satin ? The black satin isn't the best backdrop and I don't use it in the studio. In the studio I use polartec. The satin is very, very compact, and it weighs next to nothing.
Note: The black satin cloth can also be used on a bright day to drape over you and the camera so that you can get a good, clear view of the LCD screen. It slides off the camera a bit too easily so I need to think of a solution to that, but, as log as there's no wind, it works pretty well.
I hope you find the tip usefully. I think I'll try to provide tips on a regular basis going forward. If you every want to know how I did something, just ask and I'll see about doing a #CWLPhotographyTip on it. Until next time, cheers
