Browny pollution when using ND filters

[Brigham Edgar]

Only ever had ghosting with the Panchro's when stacked...do NOT stack them. By themselves never had an issue, ever! The only negative is stacking or if light reflects off the front then back onto the subject your shooting. But performance outside of this I don't think you will find better for an IRND combo.
Want bad IR effects...my F3 is like an IR camera if you stack anything...ever!

If you use a diffusion filter - you are stacking.

Rob, really...you know what I mean and so does everyone else.
