The Tiffen 6.6 x 6.6" 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 6.6 x 6.6" / 167.6 x 167.6mm.

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: 1. Sounds perfect for what I want to do. On a planned overseas trip, I will use a Canon point & shoot with a SD card, and older (early digital) Nikon with a CF card, and 2 iPhones for photos. The SD card is straightforward, but can I transfer the iPhone pics wirelessly or will I need to connect by the USB cable? Also, can I transfer from the Nikon (w/CF card) using theUSB cable? Eventually I would want to transfer copy all the photos to a Mac computer so will I need to format the device to Mac format before I use it? And one more question: when my travels are over, would this be a good device to backup all my Macs and keep the device offsite? DEP in GA

A: Hello,Apologies for the delay I hope this answer will still help you. You will have to check with WD, for direct connection from your Nikon to it. This unit has it's own wireless system, so that you can wirelessly transfer phontos from another device (laptop,camera, etc....) The catch is your other device will have to use Wi-Fi to connect to it and transfer pics.Yes you can treat this unit as a separate external HD and connect it to you MAC to download your pictures. Although I think it's a bit of over kill, I think you are better off just buying a separate external HD. for less money to can get a 2 TB ext HD.Used this unit on trips to Las Vegas and Spain (just returned) and found that the wireless aspect a bit of overkill. Good unit if you're not bring a laptop on a trip. But if you have a laptop you better off just using a small external HD and download your pics to the laptop and HD.

Q: 2. Help! Love the concept of this drive. I'd love to consider it for travel back-up of camera files BUT BUT BUT I use Compact Flash and Cfast. Is there a way to connect an external card reader to this drive ???Thanks for any clues.

A: There is no (standard) way to connect an external card reader. The device does, however expose itself as a wifi hotspot so if you have a laptop (or multiple laptops) with cardreader(s) you could use those and copy directly to the drive without having to connect the drive to the laptop.
