I have yet to try using the mask from background feature in Agisoft as I've been creating key's from a green screen background. How are you ensuring that the background exposure is the exact same with and without the subject? Exposure locking? Or does Agisoft have some tolerance when it comes to this?

While we are talking about capturing reflective surfaces with PS, have you guys seen what Ten24 has been able to do?

Non Destructive Reflective Surface Scanning using Photogrammetry

Apparently this isn't achieved by using polarization. HDR's maybe to reduce blowout? Anyone have any ideas?

Hey WickedShell,

Thanks for the update on the lack of USB trigger in Magic Lantern for EOS M. Here's hoping it gets added soon.

Thanks!

No prob guys! That's what's so great with these forums, everyone helps each other.

Also, Chad we use CHDK on our cameras and works perfect with the hubs. Just make sure the remote trigger is set to "Two Push". This allows for the first push to focus and second to fire.

Hey Guys,

What we did was create a trigger that would just simply interrupt the power supply on a standard usb hub. This way any cameras plugged in to the hub would be triggered simultaneously by the push of the switch. By default the hub is off until the button is pressed.

Then to pull the images off (still a pain and not ideal) we would just disable remote trigger on the cameras, then connect the hub to the PC to retrieve images (via Windows Picture Import). This is nice because you can then tag the images to a specific camera number.

Hope this helps!

Hey Chad,

Very cool setup! We are actually using the Canon A1400's in our camera rig, but haven't tried the DNG format due to the lens distortion. Have you found that Photoscan works around it nicely? Or do you tend to just do full zoom to reduce the effect?

Thanks!

Thanks for the info on the Canon EOS M WickedShell! This is a camera I have been looking at as well. Can you confirm if Magic Lantern adds remote trigger via USB similar to that of CHDK?

Thanks!
