The Tiffen 4 x 5.65" 1 Cool Blue Hard-Edge Graduated Filter helps to specifically add a cool, purplish-blue coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a hard-edged transition between the density and clear areas. The 1 color density provides less cool blue coloration than the 2 density filter.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 4 x 5.65" / 101.6 x 143.5mm.

Note: A horizontal orientation filter's line of transition runs parallel to the long side of the filter.

1 Density Color Graduated Filter    Cool Blue Coloring in Select Areas    Hard-Step Graduation    ColorCore Technology

Provides a deep cool blue coloring to select areas of the image.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.

Q: 5. This summer I will be traveling and Im looking to use my iPhone 5S or maybe a Go Pro 3 or 4 to record some behind the scene videos of both my travels and me doing photography. Normally I would bring my laptop but due to weight and capacity constraints, I'm looking for another solution to back-up these videos. Would I be able to transfer the videos Note, I will be in the backcountry without cell reception? FYI, I'm keen on this solution as it has an SD Card reader to allow me to back-up my photographs from my DSLR.

A: Yeah as long as you have power going into the hard drive you should be able to back up files from the SD card. It kinda just dumps it into a folder though, so if you're super peculiar about naming convention and formatting, you should use this purely as a backup solution and not wipe your cards.
