Playing with the IRIX 15 Stop ND filter was one of the most interesting experiences I’ve had.
After reviewing two of their lenses, the folks at IRIX sent me the Irix Edge Neutral Density ND32000 for review; and the experience of using it became one involving a better understanding of the environment around me, settings, the weather, etc. Yes, that’s right–it cuts out 15 stops of light. With an ND filter like this, a photographer can shoot with their camera on a tripod and not need to stop their lens down a whole lot. Instead, they can shoot at f4, f5.6, etc. While it’s very tempting to sometimes shoot at incredibly long exposures too, the photographer using the IRIX 15 Stop ND Filter should be incredibly aware of their environments. While that may sound like common sense, it’s a situation that baffled photographers who have been shooting for even longer than me.
