If you\u2019re a portrait photographer who works on location, you\u2019ll know there are lots of challenges to overcome if you want to achieve striking images. Backgrounds and available light can be unpredictable, and against these variables you still need to ensure the best detail and colour, as well as applying your own style to the storytelling. With the right technology, though, all this is possible, and GFX cameras make it easy.<\/p>\n\n\n\n

At the heart of the GFX system is a large format imaging sensor, which is the key to making successful images on location. For example, since the sensor is 1.7x larger than a 35mm chip, the photo sites on the sensor are larger, which allows for more data to be recorded in one place before it is processed. This results in significant improvements in exposure, resolution, dynamic range, and in separating subjects from backgrounds. Here, we\u2019ll go into detail on some of these advantages and see how they combine to create the unique portrait look achieved by these powerful cameras.<\/p>\n\n\n\n

The Larger Format Look<\/h2>\n\n\n\n

What makes portraits created on GFX cameras stand out from the crowd? Let\u2019s first look at what a physically larger sensor does to the look of an image. As experienced photographers know, photography is full of variables: sensor or film size, aspect ratio, focal length, aperture\u2026 they all contribute to give a particular look to an image, and small changes can define one camera system from another.<\/p>\n\n\n\n

The larger a sensor is physically, the longer the lens\u2019s focal length needs to be to get an equivalent field of view. In the case of the GFX sensor, lenses therefore need to be longer in focal length than on a 35mm camera body. This change in focal length obviously affects how perspective is rendered, how you compose the image, and how you work with the subject. It also has a knock-on effect on how apertures influence depth of field and light-gathering potential.<\/p>\n\n\n\n

Comparatively, the same aperture setting will give a shallower depth of field on a larger sensor. And while you can address this by using wider apertures on smaller sensors, thinking of \u2018a larger format look\u2019 simply in terms of shallow depth of field alone is really missing the point. After all, many portraits on large format cameras are made at smaller apertures, such as F8, which still allow great subject separation, but also maximize sharpness.<\/p>\n\n\n\n

So really the larger format look is about the convergence of all sorts of factors. For example you can roughly approximate the depth of field generated by a GFX camera by using very fast lenses on a 35mm camera, but you don\u2019t get the same tonality, resolution or sharpness along with it. And because of the 4:3 sensor format you compose in a different way, too. Basically, GFX makes you work differently.<\/p>\n\n\n\n

Bring this into the real world of location portrait photography, and what you get is the power of subject separation described in a natural fashion \u2013 one of the ideal features for any camera and lens combination. These combinations of focal length and aperture give images a distinctively different look that other formats can\u2019t deliver, and when creating portraits, many GFX users describe the results as having an almost three-dimensional quality, where focus falls away abruptly, but the subject stays clearly defined amid more natural-looking surroundings and with less distortion. Working on-location, it means that you separate the different planes of your composition more easily, with your portrait subject standing out in a striking but subtle way in almost any surroundings.<\/p>\n\n\n\n

Cleaner, Brighter Pictures<\/h2>\n\n\n\n

Making portraits on-location, you\u2019ll face all sorts of different lighting, from harsh and powerful naked sunlight to the gentle flicker of a candlelit interior. So how can the GFX sensor help with both of those? Again, it\u2019s a benefit of size.<\/p>\n\n\n\n

For starters, let\u2019s look at the latter end of the scale, and making portraits in low-light conditions. The larger a sensor becomes, and the greater its physical area, the more light it can receive during an exposure. More light means a cleaner signal, therefore portrait images that are less affected by noise than they would be on a smaller sensor at equivalent exposure settings. And less noise means truer colour and clearer details, especially when working at higher ISO settings.<\/p>\n\n\n\n

At the other end of the scale, where you\u2019re working in bright light with lots of highlights and shadows, for instance trying to balance backlit portraits with lots of contrast, G Format sensors win out thanks to their superb ability to tackle dynamic range. Typically in high-dynamic range situations, where there\u2019s greater contrast in intensity between light and shade, things may look normal to the naked eye, but when exposed by the camera, some details of the subject may be lost in the highlights or shadows.<\/p>\n\n\n\n

At its lowest ISO settings, GFX sensors can deliver up to 14 stops of dynamic range, wherein their photosites can register greater intensities of light before reaching their maximum compared to similar sensors. So you can expect images to look a lot closer to nature straight out of the camera than smaller sensors can provide.<\/p>\n\n\n\n

Maybe the biggest advantage of this superb high- and low-ISO performance is that, with a GFX sensor at your side, you\u2019re more likely to photograph with confidence, tackling new and varied subjects, no matter what the lighting conditions.<\/p>\n\n\n\n
