The differences in transparency are an artifact of how the 3D Viewer
generates its volume visualization. It is actually a series of
semi-transparent slices oriented at the closest angle to "top down" from
the camera. You can see this most dramatically if you:
A) visualize an image stack with very few slices, such as the Mitosis sample
B) orient the volume at an edge or corner, then rotate back and forth
across the border
One way to minimize the discrepancy is to use the Reslice command with
smaller output spacing, and "Avoid interpolation" unchecked. As a rule of
thumb: the closer your Z resolution is to your X and Y resolution, the less
of a discrepancy there will be.
You could also try other 3D visualization solutions with your data, such as
the BigDataViewer [1], Volume Viewer [2], or Icy [3].

Curtis
