It's not trivial to calculate from scratch the amount of light required (as you have no idea how much is absorbed, reflected etc. and it will vary according to how the lights are positioned). What you can do, is find out what shutter speed your camera meter is suggesting currently and work it out from there. You'll want to aim for 1/2f where f is the focal ...
The 70D unfortunately doesn't support controlling group C directly. It will however fire group C flashes when set to fire ALL. (Source: The manual) The Canon optical wireless flash system still contains all three groups, it is simply a limitation of the camera body. You need something like the 580EXII to control group C.
Do you know how the image was made? It looks to me a lot like some of the flower images created by Katinka Matson. They're gorgeous, but they're not photographs -- the flowers are arranged on a flatbed scanner and scanned. The way the light falls off quickly and uniformly around the flower looks a lot like what you see in Matson's work.
To hazzard a guess, I would say that the lighting was done with a twin-tube affair, with the tubes arranged above and below the lens. The upper tube was the main (more powerful) light; the lower tube was fill at about half the upper tube's power (down 1 stop, or a 1:2 ratio with the "A" tube at the top). To get the fall-off you see from front to back, the ...
I am an artist and a photographer. I do have a knowledge I got from my teachers at the art school which may answer your question regarding "why left oriented lighting is preferred" Most of the artists in the history, including the academic photographers, designers, sculptors, studied nature to understand objects and light. Most of them studied pencil ...
You may find useful this wikipedia page You can calculate the exposure value with the given formula: EV = log2(N^2 / t) setting: N = the f-number (aperture) you will use t = the exposure time you will use they both depends on your camera: search a middle aperture for your lens and a time you will likely use (a rule of thumb is that the slower time ...
The main reason why there will be reflection on such a surface will be due to light spillage and light bouncing off bright walls. my suggestion is to block this light spillage with Matt Black Cards Set up your panels; standing or flat, makes no difference, it is how you wish to display them so that you are able to show the maximum beauty of each panel. Get ...
It's also very possible that the outside was darkened in post. The light might be from a twin-light flash where you can aim the lights more precisely. http://www.bhphotovideo.com/c/product/239656-USA/Canon_2357A002_MT_24EX_Macro_Twin_Lite.html
I agree with @claraonager: anyone in attendance gets to be a gaffer. I just found some "nano" paracord and picked up a 300-foot spool to add to my bag, but have not used it yet. Small (half-inch) binder clips pack in a small light space, easily grab a cloth, and have a handy place to tie paracord on. Look at surplus "space blankets" for reflector ...
