Microsoft’s Surface Pro 2 and Phase One’s IQ180
Background in a Nutshell. When Phase One released its IQ180 digital back, its full frame medium format sensor boasting a staggering 80 megapixel resolution was not so surprising. What took the high-end medium format photography community by storm was its large high resolution retina touch screen. Prior digital back screens were postage stamps by comparison. The IQ180 and her sisters the IQ160 and IQ140 were indeed groundbreaking, easily surpassing the viewing screens of its competitors and even those of the smaller format DSLRs such as those offered by Canon and Nikon. Phase One’s sister company, Leaf, released similar high resolution retina touch screens on its Credo line of digital backs.
Phase One now offered “live-view” on its IQ series and Leaf Credo digital backs, but live-view on a CCD sensor is quite limited in comparison to live-view on a CMOS based DSLR. Furthermore, the size of MFDB CCD sensors with its high sensitivity often meant that the sensor was overexposed in live-view mode. Consequently, stopping down the aperture and/or using neutral density filters are often necessary to enable this rather limited live-view function. The Phase One IQ series offered focus-mask, which in my opinion was a sleeper surprise feature on the IQ series digital backs, one that quickly overshadowed the claimed benefits of having live-view. But in a fast moving tech world, the clamor still continued for true live-view, something DSLR CMOS sensors could accomplish well whereas the much larger CCD sensors of MFDBs could not. And again, the voices clamoring for live-view continued, and Phase One answered with its recently released IQ250 MFDB, the world’s first CMOS sensor digital back—with true live-view.
But regardless of live-view capabilities, the most significant limitation on the effectiveness of live view on location is the physical size of the screen. No matter whether DSLR or MFDB, the screen size on the back of a camera or digital back is still limited to about three-inches in width, or about the size of a credit card. Regardless of technology, this is a physical limitation that can not be overcome absent an external monitor. When combined with tired aging eyes, the difficulty of the challenge becomes more pronounced and the proponents of true live view on a diminutive three-inch screen suddenly discover that it is not the panacea that they had been clamoring for.
Tethering in studio is not a problem where powerful computer workstations can run fully featured versions of Capture One Pro software, viewing full resolution digital raw files on large monitors. In prime conditions it is relatively easy to check composition, exposure, and focus. The difficulty or challenge is viewing images while on location with a larger portable screen option. Tethering on location generally requires using a laptop solution mated with tethering options such as those offered by Nine-volt.com. For architectural and interior photographers where size, weight, or carrying equipment long distances is not as much of a concern, tethering with a laptop with a larger 15″ or 17″ screen may not be a problem. Nine-volt offers flexible solutions and I have been able to successfully mount a laptop with a 17″ screen on the DigiPlate Lite, although a 15″ laptop is the largest recommended configuration.
However, size and weight is often a significant concern for landscape photographers and other photographers working on location. A tablet provides a much better form function over a laptop, especially where size and weight are primary considerations. Despite a large selection of tablets on the mainstream market none have had the power or memory necessary to tether a medium format digital back. None, that is, until the introduction of Microsoft’s Surface Pro 2. And I’m not talking about the use of Capture Pilot and viewing scaled down JPEG files on an Apple iPad. I’m talking about viewing full resolution RAW digital files from an 80 megapixel digital back using a fully featured version of Capture One Pro 7 —all in a small tablet format. That’s a game changer.

The Game Changer. A tablet has a better physical form factor for both traveling and viewing in the field than the clam shell configuration of a notebook or laptop computer, a popular selection being the Macbook Pro or MacBook Air. When tethering, additional accessories are helpful to secure the laptop to a tripod for ease of viewing. There is no doubt in my mind that Nine Volt’s DigiPlate is the finest solution for a laptop tethering. For those with a Macbook Pro or Air, look no further than Nine-volt. The DigiPlate and DigiPlate Lite are both well-crafted and CNC machined from aircraft grade aluminum and allow for infinite configurations and tethering options. Both are designed with laptops in mind and although I could attach the Surface Pro 2 tablet to the DigiPlate Lite, I found myself wanting a smaller and lighter on location solution yet—as even the DigiPlate Lite weighs almost as much as the Surface Pro 2 tablet itself. I have instead decided to use the Nine Volt tethering solution in studio only.
The Microsoft Surface Pro 2 tablet weighs two pounds. It is smaller and lighter than a laptop, but heavier and much more powerful than a typical small tablet, casting itself as a red-headed step-child among a large, rather uniform, and ordinary field of tablets, notebooks, and laptops. There really isn’t an equivalent piece of hardware readily available in the mainstream market. The Surface Pro 2 measures 10.81 x 6.81 x 0.53 in, with a 10.6 inch HD touch display with a resolution of 1920 x 1080. It sports a fourth generation Core i5 processor, 8GB of RAM for those selecting the 256/512 hard drive option, blue tooth, a micro SD card slot (adding up to another 128GB of storage), and a full-sized USB 3 port essential for tethering the Phase One IQ series or Leaf Credo series MFDBs. Battery life is excellent. It is essentially a laptop in tablet form that can run a full version of Capture One Pro 7. This changes everything.

Tethering on Location. Size and weight are major considerations when working on location, especially when you have to hike any considerable distance to your destination. The Surface Pro 2 tethering solution adds no more than 3 pounds total to my pack, including the Arkon heavy duty c-clamp universal tablet mount, which attaches to my Really Right Stuff TVC-24 carbon fiber tripod. Set up is quick, taking no more than a minute. The tablet mount features two ball joints allowing me to maneuver the Surface Pro 2 in any position quickly and easily. Some care needs to be taken to avoid over tightening the c-clamp and damaging the tripod leg. I placed thin adhesive rubber strips inside the c-clamp which adds grip while also protecting the tripod leg from potential scuffing. I have placed strips of gaffers tape around the tripod legs to quickly mark where to attach the Arkon c-clamp and also provide further protection to the tripod legs. I chose the Manvex case for protection, and leave the Surface Pro 2 in the case even when using the tablet mount. The Manvex case provides a secure holder for the stylus pen. In the above photo, I have chosen to position the Surface Pro 2 directly below the digital back on the camera. The Surface Pro 2 boots up quickly to a nice clean desktop, having opted to bypass the messy desktop of Windows 8 using a neat free program called Classic Shell. Seconds later, Capture One Pro 7 DB is ready. The program recognizes the IQ180 automatically after plugging in a short three-foot USB3 cord connecting the digital back to the Surface Pro 2. This is just too easy.

Although Capture One Pro 7 can be used to tether a DSLR or Phase DF with digital back, the real advantages become apparent when using a technical camera. The larger screen of the Surface Pro 2 makes it easier to compose images, check settings, and check focus using Phase One’s Focus Mask feature. Since the Surface Pro 2 is running a full version of the Capture One 7 raw processing software, all the features of the program remain accessible, though my intent is to use the Surface Pro 2 more as a tool on location and process the image files later on the studio’s workstation. The convenient tablet form factor and the capability of the Surface Pro 2 to run a full version of Capture One Pro 7 is ideal for landscape photographer and is also an attractive tethering solution for architectural and interior photographers as well.
Full image view. Note the approximate area of the image marked by the yellow rectangle on the screen.
For working on location, I have chosen to set up my Capture One Pro 7 work space to maximize the viewing area of the main image. Once the cable release is triggered, the image captured by the IQ180 MFDB appears within seconds on the Surface Pro 2′s high resolution screen. Too bright outside? Simply tap in the bottom right corner and adjust the brightness of the screen to match. Double-tap on the screen and the program automatically zooms in 100% to check focus. Tap the Focus Mask tool to assist and the sharper areas of focus appear painted in green. The Focus Loupe tool or any other tool in C1 Pro 7 is also available to use on the full 80 megapixel raw file.

Once on screen, the image can be moved around to inspect other elements of the image simply by dragging a finger on the screen to the area of the image desired. Viewing the preview image on the larger screen of the Surface Pro 2 makes it much easier to check composition, focus, and even the desired amount of lens movement afforded by technical cameras. Changes can be now be quickly and confidently made on the camera or digital back before again triggering the shutter for the final image capture. Once satisfied with the final image, an LCC image is taken to assist later in post-processing with Capture One Pro 7. The IQ180′s 80 megapixel image files are stored on the Surface Pro 2′s hard drive and later transferred to the studio’s workstation for processing. I’ve never been much of a fan of tethering, however, the Surface Pro 2 changes everything at least for when I’m working on location with my Cambo WRS technical camera. For my typical workflow, I do not see myself using the Surface Pro 2 to photograph tethered in studio, although its Windows 8 Miracast WiFi capability to send images to other Miracast enabled monitors, such as high resolution viewing tablets and high definition widescreen televisions, has potential worth investigating.
Live-view still remains an option on IQ series and Leaf Credo series medium format digital backs, and except for the CMOS-based IQ250, are still limited by the constraints of its CCD sensor. Live-view via USB3 may still be an option on the Surface Pro 2 and C1 Pro 7 enabled later via Phase One firmware update, however, in my opinion, I do not expect any further improvements in live view capability to be implemented with CCD sensor-based digital backs, although I surmise that live view on the ten-inch screen of the Surface Pro 2 will be better than on a three-inch MFDB screen . My understanding is that live-view via USB3 firmware update is now in beta testing. In the meantime, I find that using focus mask and other tools within C1 Pro 7 on the Surface Pro 2 on full resolution raw files to be faster and more effective than working with a limited version of live-view and neutral density filters. Even the IQ250 and DSLRs, with their true live-view capabilities are still limited by the physical size of their viewing screens. Indeed, the IQ250′s true live-view via USB3 (if enabled by firmware) on the larger screen of the Surface Pro 2 may be something to really silence the live-view pundits. *update* Live View via USB3 on the Surface Pro 2 is now possible with the latest firmware 5.11.36 update for IQ backs and C1 Pro version 7.2; all CCD sensor limitations on live view remain, but is more usable on the larger screen of the Surface Pro 2 as expected. Life is indeed good with options!
The Verdict. For Phase/Leaf/Mamiya medium format digital backs that are USB3 capable, the Microsoft Surface Pro 2 is an ideal tethering companion on location. The tablet format does take some getting used to but its form factor and power is exactly what makes the Surface Pro 2 unique as a tethering tool, especially in the world of medium format digital photography. The tablet is lighter than a laptop and consequently does not require as strong of a mounting clamp to attach to a stand or tripod. This means less bulk and less weight. When traveling the Surface Pro 2 can serve double duty replacing a laptop while also providing a small but capable tethering solution. The Sony Vaio Tap 11 or the less expensive first generation Surface Pro are alternative tablets that could be considered, but their performance does not appear to be as good as the Surface Pro 2 running programs under Windows 8.1. Further, battery life for both of these tablets in the field is substantially shorter than that offered by the Surface Pro 2. While tethered to the Surface Pro 2, images from my 80 megapixel Phase One IQ180 appeared on screen in Capture 1 Pro 7 DB in a scant three to five seconds. Battery life in the field for the Surface Pro 2 is rated up to ten hours but I would rate it conservatively in the field at about seven hours. At least one review points out that the Surface Pro 2 has better color performance than the first generation Surface Pro. The Cintiq Companion was not considered as the larger 13″ tablet is almost twice the weight of the Surface Pro 2, which would necessitate a heavier clamping option and further limiting tethering portability in the field.
The Surface Pro 2 has a faster fourth generation Core i5-4300U processor at 1.9GHz base and 2.9GHz Turbo, an increase of 19% at the lower end and over 11% in turbo compared to the first generation Surface Pro. The Surface Pro 2 also offers 8GB of RAM over the first generation’s paltry 4GB of RAM. Consequently, the Surface Pro 2 is capable of much faster image viewing, taking only three to six seconds for a full image preview to appear on its screen via C1 Pro 7. Processing time to tethered viewing varies according to the resolution (40, 60 or 80 megapixels) and type of digital back being used. The Surface Pro 2 also has substantially longer battery life. The tethered view in the field from either Surface Pro generation is still magic.
There are two items that I don’t like about the Surface Pro 2. First, the Windows 8 operating system to me is like Vista was to XP. It’s like Microsoft just couldn’t help themselves and leave well enough alone with Windows 7. The Windows 8 desktop is a messy social enabled interface. I am sure it’s fine for many, but I’m here to work. Some may recall why the term “desktop” was even developed: software engineers likened the “computer desktop” screen as replacing a real office desktop, as in papers, folders, and projects on your desk. I want a clean office desktop, and the Windows 8 interface is busy, messy, and trendy. Thankfully there are a host of free programs such as Classic Shell that address this minor shortcoming, allowing you to boot directly to a nice clean desktop similar to Windows 7, with a C1 Pro 7 shortcut icon now plainly visible. No more useless clutter. Finally, the magnetic holder which doubles as both the battery charger port and pen stylus holder on the side of the Surface Pro 2 is gimmicky. I find myself spending more time making sure that the magnetic connection is secure enough to enable charging without inadvertently being bumped off. Using the magnetic holder to store the digitized stylus pen is almost insuring its eventual loss and replacement. The charger works well enough, but storing the stylus pen is much better in the pen holder provided by the Manvex case.
There are a host of accessories available for the Surface Pro 2, including the Touch/Type 2 back lit keyboards which attach magnetically (which does work very well) or by wireless blue tooth, and wireless blue tooth mice. All of these accessories are best left in your bag (except for the digitized stylus pen) when tethering on location. Unless Apple releases an iPad Pro, Microsoft’s Surface Pro 2 currently stands alone as the ideal tablet tethering solution on location. Lighter than a laptop or notebook, yet heavier than a tablet, the Surface Pro 2 has not been as widely embraced as a powerful hybrid computer tablet that maybe it should. But for photographers seeking to shoot high-end medium format digital backs tethered on location, the Surface Pro 2 is indeed a game changer. It is a worthwhile investment for Phase One IQ series and Leaf Credo medium format digital back users.
