First of all thank you for the great device, software and webinars.
I read the book "GDV in medicine" and it is stated there that one could/should use a Filter in some cases. When I was at an institution a few months ago, 2 GDV measurements were made, one with and one without filter (a thin film of dark color), but they were using an old model of the GDV camera. The question that arise are:
Do we still have the possibility to use a filter withe bio-well device?
Does the application of a filter make sense with the new devices?
If we can use a filter, maybe some information about what the filter does technically and with the results would be great.
