I am photographing an onion and would like to create a lighting pattern similar to this..
I have the onion in a light box I created, using a white sheet as the cover and laying on a black felt. The flash was outside the sheet on the left back with a book serving to restrict the light to the back portion of the onion. 1/64 power on the flash.
I am not getting the one sided lighted with the opposite dark or darker. What am I doing wrong?

| One thing that immediately comes to mind is that you may have the white sheet (lightbox) on on all sides of the onion except where it is sitting on the felt (you said that you laid the onion on black felt) and the light is reflecting off of that. If this is the case, you will need to subtract that light from the equation. |

| Also take a shot with the same settings, but without triggering the flash. You should be seeing as close to black as possible (to ensure you're not picking up any ambient light from anywhere) |

OK, I brought the felt around opposite the light to knock down reflections and increased the power of the flash so the flash is providing more light that the ambient light. I also under exposed the image and let the flash serve as more of the light.
I got a lot of "felt" in the image on the left and knocked it out with Lightroom. Is there any way to avoid that felt being picked up without PP... ie: for a basic challenge? |

more distance between the onion and the felt that is draped behind/around it

Also, not sure if you did this when you set up the felt, but make sure it is draped and forms a nice curve. It will absorb light better. If you're still getting a reflection off of it, change the orientation of the curve in relation to your light source so that it is a bit less oblique. Kinda hard to explain in words...so here is a terrible Paint illustration which hopefully will help. |

Drop your ISO back to 100, Pump the flash brightness up and also the aperture to restrict how much ambient is coming in to play, work around f11 maybe even as high as f16 this will ensure only the parts hit by the light are illuminated. Play around with it from there and you should be able to get the effect you are after.

Is it just me, or is it going to be difficult getting the onion in the shot if it's behind the camera? :P

the diagram is two of separate views - the top left and the bottom right. Top left is showing the placement of the onion in relation to the felt background and the bottom right is like an aerial view of the entire set-up.

| are you diffusing the flash? try direct light and meter on the highlights... |
