The Cokin Z-Pro Series Hard-Edge Graduated Blue 0.6 Filter is designed for use with a Cokin Z-Pro Series Filter Holder. It can be used to add blue to a hazy or colorless sky. When used instead of a polarizer filter to enhance the sky within an image, the desired effect can be applied only to the sky, without any unwanted polarization or additional contrast to any part of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A graduated filter with a hard-edged line of transition is useful for images which include defined horizon lines. This filter has up to a 0.6 density and reduces light from entering a lens by up to two stops.

This filter is made of durable, optical resin (CR39) and measures 1.6mm thick.

Q: 7. 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.

A: Yes, it will work with 2.0. Less transfer speed but it will still work fine.

Q: 9. Will the software support Canon RAW files, so that I can back them up on the drive AND view on iPad from the drive?

A: Sort for the delay...the answer is NO ! But the drive work fine. You need to export on your computer to convert...
