Here is the diffuser in place. The black lump on the camera is a Canon ST-E2 Speedlite Transmitter. Flash units are not shown.Hi Rik.
I promised I would show you the Chinese Lantern Diffuser.
It is a simple 8 inch cylinder paper lantern, $3.50.
I cut out the bottom and added a 1/4 inch thick ring made out of steel and powder coated flat black.
I used some para-cord and a cord cinch to handle attaching it to the camera.
This is about as simple as it gets. It follows the camera and lens up and down.
This one has a full stroke of 15 inches.
I am working on a nylon version that is 10 inches in dia with a 20 inch throw.
You just point a couple of 430 EX flashes at it and it's done.
This is not very sophisticated but it is easy to build and works real well.
Please feel free to share this idea with your friends.
Below, a sample image made using it with a highly reflective subject (orchid bee). Canon 6D, 100mm Macro at 1:1.
Shown below are other stages in the setup...
Here a specimen has been secured on a glass slide with a small ball of dental wax. The slide is placed on a clear table with a photo gray card beneath it. This will give a soft neutral background.
Next the bellows is placed over the specimen with its weighted base on the table top. The attaching cord is fully extended.
Here is another view of the bellows diffuser ready to be attached to the camera.
Finally, pull the diffuser up so that the lens enters the hole on the top. Secure by tightening the straps over the camera, as shown in the first image above.
Just point the flashes in the general direction of the diffuser and you will have a nice soft fill light.
