Key takeaways
- Set your camera to Kelvin mode (5500K+) or cloudy preset. Phone cameras default to warm tones that turn blue ice grey. Manual adjustment brings out the cyan that makes the cave magical.
- Ice reflects light intensely. Increase exposure by +1 to +2 stops to prevent underexposed, muddy shots. Check your histogram and adjust as clouds shift during the 4-hour hike.
- Cold drains batteries fast. Carry spares in an inside pocket close to your body, and swap them frequently. Lithium cells last longer than alkaline in freezing conditions.
- The cave interior is dim even at midday. A small headlamp or LED panel illuminates ice details and lets you shoot handheld without boosting ISO to noisy levels.
- Tripods are impractical on ice in crampons. Brace yourself against the guide, use image stabilisation, and shoot at faster shutter speeds. Monopods are awkward too.
Why Blue Ice Looks Grey on Your Phone
The blue of Vatnajökull's ice caves exists because glacial ice is compressed so densely that it absorbs red wavelengths of light and reflects blue back. Your phone's camera, however, uses automatic white balance to 'correct' what it perceives as a colour cast. The sensor sees deep blue and interprets it as incorrect lighting, then neutralises it toward grey or white. This happens in milliseconds, before you even press the shutter.
To override this, switch your phone to manual mode if available, or use a third-party camera app that lets you lock white balance. Set the white balance to a cooler temperature, around 4000-5000K, which tells the sensor to preserve blue rather than neutralise it. If your phone has no manual control, try taking the shot in shadow first, where the camera will set a cooler balance, then recompose in the ice cave light. Most dedicated cameras (mirrorless or DSLR) also default to auto white balance, so check your menu and select a daylight or cloudy preset instead.
Protecting Batteries and Electronics in Glacier Cold
The 4-hour duration of this glacier hike means your camera and phone will spend extended time in temperatures well below freezing. Cold slows chemical reactions inside batteries, and a camera that shows 40% charge at ground level can drop to 5% within minutes once you're on the glacier. Lithium batteries are hit hardest, losing roughly half their effective capacity for every 10°C below freezing.
Keep spare batteries inside a pocket closest to your body heat, wrapped in a thin cloth. Do not leave batteries exposed to the air. Condensation poses a second threat: when you move from the cold glacier into a warmer shelter or vehicle, moisture will condense inside your camera or phone before you can feel it. Place your gear in a sealed bag while it warms to room temperature, ideally for 30 minutes, before opening it. Some photographers tape a small pouch of silica gel inside their camera bag as additional insurance against misting.
Correct exposure reveals the true blue of glacial ice inside the cave
Light and Timing Inside the Ice Cave
Ice caves are dimly lit, fed by daylight filtering through cracks and fractures above. A headlamp is not strictly necessary if you have a camera with reasonable low-light performance (ISO 1600 or higher), but carry one anyway for safety and to illuminate your guide's face and details nearby. The cave's blue deepens and intensifies during midday hours when the sun is highest and most light penetrates the ice mass. Early morning or late afternoon visits will show flatter, greyer tones because light enters at a shallow angle.
If your goal is vibrant blue, aim for a tour between 11 a.m. and 2 p.m. Camera settings in the cave should start at ISO 3200, f/2.8, and a shutter speed of 1/30th of a second or faster. Your phone will struggle here; if you are using only a phone, enable night mode or long exposure if available. Bring a small tripod if you want sharp shots without camera shake, but be aware that setting up a tripod while wearing crampons and standing on ice requires careful balance and takes time your group may not have.
Shielding Lenses from Meltwater and Ice Spray
Vatnajökull's glacier surface is alive with meltwater, especially in warmer months. Drips and spray land directly on your lens, and ice crystals can scratch glass if you wipe them dry with a cloth. The best defence is a UV filter, a clear optical element that sits permanently on your lens front. It costs far less than repairing or replacing a scratched primary lens, and you can clean it freely without risk. Carry lens cleaning wipes designed for outdoor use, and gently brush off crystals with a soft brush before wiping.
For phones, a waterproof case rated to at least IPX7 is practical if you plan to shoot stills, though it will slightly degrade image quality and make touch controls harder in gloves. Keep a microfibre cloth in a dry pocket for clearing your viewing screen mid-hike. Never use your jacket sleeve or glove fabric; these trap grit that scratches on contact. If you must use direct hand pressure to shield your lens from spray, cup your palm around it rather than touching the glass.
Photographing Your Companions on Roped Terrain
The group is limited to a maximum of 12 guests per guide, and everyone will be roped together for safety while traversing the glacier. This constraint makes dynamic action shots difficult. Avoid asking someone to pose unnaturally or turn around; instead, photograph people as they walk naturally in line ahead of you, with the glacier and ice cave formations framing the background. The rope itself tells the story of the experience and grounds the shot in reality.
Your guide and companions will be wearing crampons and harnesses, which look dramatic but also pose framing challenges. Shoot from a low angle to emphasise the scale of the glacier and the ice cave walls. Wide lenses (24mm or wider on a full-frame camera, or the widest setting on a phone) work better than zooms in confined ice cave spaces. Avoid shooting directly into the brightest part of the cave wall behind a person, as this will silhouette their face; instead, position yourself so light comes from the side or behind them, illuminating both their features and the blue ice simultaneously. Always alert your guide before stopping to compose a shot, so the rope team can pause safely.
Gear Setup Before You Leave Skaftafell
Off-road transport takes you from Skaftafell to the foot of the glacier, meaning your camera bag will experience vibration and jostling. Pack your gear in a padded camera bag with dividers, securing it so nothing shifts during the drive. Bring a dry bag or waterproof stuff sack inside your main pack for electronics, separate from your other belongings. The experienced English-speaking glacier guide will provide all necessary glacier safety gear, including crampons, helmet, walking ice axe, and harness; your only responsibility is keeping your camera and phone functional.
Wear gloves rated for both cold and dexterity so you can still operate camera buttons and touch screens. Thin merino wool or synthetic liner gloves under slightly thicker shells work better than heavy mittens. Bring extra gloves if possible, since wet gloves lose insulation quickly. Charge all batteries and memory cards fully the night before. Expect to shoot roughly 200 to 400 frames during the 4-hour tour depending on light and your pace, so carry at least two memory cards in case one fails.
Aerial and Drone Photography Restrictions
Vatnajökull National Park has regulations governing commercial and recreational drone use. Drones are not permitted for independent visitors in most glacier zones, including areas where this tour operates. Even if you own a drone, launching one on the ice without explicit permission from your guide and park authorities is prohibited. The restricted airspace protects other visitors, wildlife, and the integrity of the park's management zones.
If aerial perspectives are important to you, discuss this with your tour operator before booking to see if licensed aerial photography is available as part of a separate service. During your glacier hike, focus instead on ground-level compositions that showcase depth and scale. Wide-angle shots of the group descending into the ice cave, or close-ups of the blue ice texture with compressed air bubbles, often deliver more impact than a distant overhead view anyway.
