Asking to see my setup is a great complement Matthew as I know how good you are in product photography. I doubted a bit to show it because it is so poor... but then again I thought as a good
strobist that you are you will not judge my lack of equipment but the creativity... Anyway, please excuse my rudimentary setup...
We start with the reflection. My pieces are placed in a glass (35 X 25cm) that has been painted previously with two layers of black acrylic. To protect the painting as it comes off very easily I pasted a black cardboard. This painted glass will give you the sharp reflection. Then I worked my lights just above the pieces. I can't have my light exactly above because I have a low roof in my room and I don't have the arm, so I just work close the my soft box. In this case I used a strip of black carton around the soft box, this will make my background black as light is not lighting the cloth. (this is important)
The light will be hard in the pieces but will give light to my reflection so I have two options. One use a hard diffuser but the light will be even on the pieces, or to use a gobo and give some shadows.
The next step is to give light to the pieces from the side, so you place a reflector to give them light. This reflector goes from the background cloth to the foreground... in the back I have a black sheet of paper, so the light will not be reflected in the black cloth, but the problem comes when you need different light values in your picture as I have two white shells and one blue. So I paste another strip of black paper in the reflector not to give light to my shell in the foreground. I will be just bouncing light with a little strip of white reflector.
I know it is complicated, and maybe I could get the same results by doing all in photoshop blending exposures and masks and all... but I find easier to get my picture right from the beginning...
Here is the setup
#S1
this is the picture I got, it comes out of lightroom. As you see it is a nice picture to work with colors, contrast or any other treatment you want to give.
#S2 with diffuser
#S3 with gobo
This is a very easy photography because you don't even need flash to do it. You also can work with natural light. Just by taking care about the light.
here is a simple setup. My light comes from the roof, so I use a gobo to the light pieces and a diffuser (my dearest bowl) to diffuse my light. I use tripod and long exposure.
#S4
#S5 this is the result.
In all the result pictures I only worked my curves to give contrast.
#3 and #4 and all pictures of this setup and stills I post now are taken with a P&S (Canon G9), my soft box is an octagonal 60cm with a 300WS studio flash.
I really don't know how well I am doing when I am working most of my still with my G9, instead of my 5D. I posted a question about this in another thread because I am a bit worried about printing. I don't know if it makes any difference taking my pictures with a P&S or with a DSLR with good lens when it comes to print.
The reason I use the P&S is that gives me very sharp pictures, very easy to carry around, and I can use HSS (1/2500 sec) which is some cases is useful.
If you, Matthew, or anyone else have a question about my setup, feel free to ask, I would try to help.
