The Singh-Ray 67mm LB ColorCombo Warm Circular Polarizer/LB Color Intensifying Filter combines the best of two photographic worlds. For any outdoor shooter, a polarizer is a "must" while for those interested in "stepping up" the color intensity, an enhancing filter is the proven way to go.
With this Combo filter, Singh-Ray has made an improvement in their previous Polarizer PLUS Color Intensifier filter by making this updated version at least 1-stop faster - certainly a benefit in marginal light or hand-held photography. In addition, the thinner mount version of this filter makes it useful on lenses as wide as 12-24mm - again a big plus when shooting vistas.
The LB Color Combo Warm Polarizer/LB Color Intensifying Filter should also be used in conjunction with Singh-Ray's Galen Rowell Graduated Neutral Density Filters. The "lighter and brighter" transmission the filter provides really helps you accurately position the grad as you're looking through the viewfinder.
