First Exposure: Phase One IQ260 and IQ280 Digital Backs

Photographers often take pleasure in criticizing high-end photo hardware and software, and the severest critics it turns out have often never used the gear. Having spent weeks with the new Phase One IQ260 and IQ280 digital backs, I can report that they deliver superb image quality, and the new features extend the capabilities of the backs for the photographers who need them. That’s not to say that there isn’t room for improvements and tweaks in some areas. And as a Nikon D800E user on a daily basis in my commercial studio work, I find the dynamic range and the ability to capture fine detail at low ISOs visibly better with the IQ280, despite a popular report to the contrary.
While landscape photographers can achieve this same result with an IQ180 back, advertising, commercial and fashion photographers shooting both in the studio and on location will be interested in the new wireless capabilities of the IQ2 backs. In the studio, with Capture One connected to my studio wireless network and my iPad running Capture Pilot also connected, a preview of every capture is sent from the camera to the iPad. Well, almost every capture. The connection wasn’t particularly stable, which could have been the fault of my studio network, not Phase One. When it was working, however, my client was able to see and approve the captures I was making of a vintage 1953 Fender Stratocaster while remaining out of the shooting area.
I had even better luck with the wireless connectivity away from my studio. The IQ2 backs are also capable of creating a direct (ad hoc) wireless connection to an iPhone or iPad, without connecting through a computer running Capture One. The image on the 3.2-inch, 1.15-megapixel IQ2 touchscreen is very nice, but evaluating your capture on an iPad is far easier. In theory, you can even adjust exposure and trigger the camera using Capture Pilot running on your iPhone or iPad, but this wouldn’t work for me in the studio and was hit or miss on location.
I use tethered capture for my Windows 7 computer exclusively in the studio, and I was happy to see that the IQ2 backs use USB 3 for this. The FireWire 800 port is still available, but I don’t have FireWire 800 on my computer. Thanks to tech support, I finally found the USB 3 port on the left side of the IQ280 back below the CF card door. But, the USB 3 connection, at least on Windows machines, is still a work in progress. While captures transferred quickly and reliably, I was unable to use Live View, adjust settings, or trigger the camera with Capture One software through the Windows USB 3 connection. By the time you read this, the problem may be sorted out for the IQ280. These features would have been nice to have with the camera suspended 6 feet directly above the guitar. But even without them, the final images are stunning in their detail.
The bad news is that you need a lot of experience to determine the exposure. Even the Sekonic L-758DR only meters in incident mode to EV-2 (at ISO 100), which is the light level of moonlight from a full moon. For areas darker than that, you must rely on experience or luck.
I relied on luck and captured an 8-minute exposure at f/5.6 and ISO 400 underneath a pier where all I could really see was the white of the breaking waves. The image quality is amazing. When I guessed badly, the IQ 260 had so much dynamic range that I was able to process an overexposed 8-minute photo at f/11 of the pier to a usable image in Capture One.
I had great luck with the IQ260 in the studio, both with tethered capture and in the wireless mode. In tethered mode with the USB 3 connection, I was able to trigger the camera and adjust shutter speed, aperture and ISO. The connection was not as stable as it should be, and Live View would not work, but Phase One says it is sorting this out.
It took me a few minutes to sort out the wireless connection. The iPad Capture Pilot app kept attempting to connect to the IQ280 that I had previously used. After manually entering the host name and IP address and selecting the IQ260 address in the iPad Settings panel, I was able to connect. With the IQ260, I am able to adjust the camera setting and trigger the camera. Now all we need is a technological leap so that we can transfer the 55-70MB IQ2 RAW files wirelessly to our computers.
