Great little rig  :)
Good to see someone do this, I played around with macro scanning a few years ago but never had the free time to put into it.

I would have thought that polarisation would help your project quite a bit, as a good polarised lighting rig combined with a polariser on the camera would give the ability to capture both diffuse and specular images.

Depending on the quality of the polarisers and position of the lights & camera you should in theory be able to elminate the specular reflection entirely by using cross polarisation.

If you have the abilty to "toggle" the polarisation angle between 0º and 90º, which as your subject does not move (not alive) you would not have to do very fast, perhaps just one polariser in front of the camera that can be rotated from 0º to 90º.
Then you lights only need one polarisation state ( i.e fixed linear polarising filters).

The issue I can see with all the above is that I suspect that your lighting dome and the position of the LED strips will change the angle of polarisation coming from the lights.
Ideally you would need a sphere of evenly spaced lights around the subject all pointing directly at it.

Having said all that I'm sure it's worth just putting a polarising filter in front of your camera and seeing if it helps fix the issue of the spyhole reflection.

The ShutterCell cannot be directly triggerd by Smart Shooter software.

You could though use a very basic Arduino / micro to trigger the ShutterCell input channel, how this could be intergrated with Smart Shooter is another matter and a question for the makers of Smart Shooter.


DNG support would be most welcome indeed  ;)

love the design !
the folding? flightcases is a very clever idea 8)

I always used to use collada export with C4D, you get the cameras then as well if needed.
I have not tried for a very long time though, as I now use Zbrush for UV and mesh clean up instead... much much easier and nicer than C4D :)


General / Re: Raw file batch calibration/sync of image exposure?

You could try using Raw Therapee  --

You should be able to save a " profile" for one image and then apply this to all the others and batch them

Hope that helps,

Yes.. or at least they were a while back and I presume they still are.

What a weird thing to put on kickstarter  ::)

Smart Shooter supports Nikon and is a lot cheaper than Breeze

Hi Christian,

IF you don't use USB communication on the DSLR rig, then what do you use to download the images ?  WiFi cards ?

Hey Manuel,

The test result looks really good, well done !

The machine looks crazy , like it should be in space 8)
The little flashes look cool too.... get some nice connectors and throw away those choccy bloc (connection blocks) though ;)

Here's another video of the rig that shows a little bit more  ;)

@Mfarnquelo... how are the mini flash going ? they sound quite crazy but cool!

Here's a little sneak peak / teaser of the rig I mentioned previously

Linear polarising filters on both cameras and lights would help with specular.
