Tips for photographing ice caves

Ice caves are unique geological structures formed within glaciers that provide special photographic opportunities and memorable experiences. As meltwater bores through centuries-old ice, it creates caves, tunnels, and chambers lined with translucent blue walls. These icy interiors offer unique lighting effects, textures, shapes, and colours to capture.

However, photographing ice caves poses several technical and practical challenges. The combination of low light, odd reflections, extreme contrasts, cramped spaces, and uneven surfaces requires patience and some understanding of your camera. Equipment such as wide-angle lenses, sturdy tripods, and off-camera lighting allow capturing high-quality images.

How to photograph in an ice cave

Iceland is home to a number of ice caves formed within the country’s glaciers. These caves are constantly changing as meltwater carves through the glacier ice. Each ice cave offers unique compositions and lighting for photography. Go with an open mind and ideas but see what is there on the day. Every ice cave changes with time so even the best planning will not always result in the experience you planned.

Equipment

Many of the ice caves in Iceland are a distance from any main roads or infrastructure. It is essential that you have everything that you need before you set off. Once on the road (or glacier) then there is no turning back.

Check with your tour guide what is provided before you meet. Most will supply helmets if needed and crampons, but always check what is included.

• DSLR or mirrorless camera with manual controls and high ISO capability
• Batteries stored in a warm pocket
• Sturdy tripod
• Headlamp or torch
• Warm, waterproof clothing and boots
• Helmet
• Crampons or ice cleats

Safety

When entering an ice cave you need to listen to the warnings from your guide and follow instructions carefully. The ice caves are dangerous environments and ice falls are not uncommon. A lot of the time the path is marked by boards and ladders and these can be icy and slippery with water.

In Iceland, it is not possible to visit the ice caves without an official guide. If you want time in the caves for photography always check with the timetable of the tour and visit first thing or last things when the tours are quieter.

Locations

Popular guided ice cave tours operate at Vatnajökull Glacier or Myrdalsjökull Glacier. If you do not want to go on a guided tour then you can see the glacier at Hoffellsjökull Glacier Lagoon and Fláajökull Glacier Lagoon although there are no ice caves. These two glacier lagoons are much quieter than other locations. Access to all ice caves requires challenging hikes over icy terrain unless you book a tour that includes an all-terrain vehicle and even then some hiking is needed.

Camera Gear

A digital SLR or mirrorless camera provides the image quality, controls, and lens flexibility needed to photograph ice caves. Look for a camera with good high ISO performance as you may need to increase the ISO in the low light. Having full control over the exposure setting with a manual mode will help. Manual mode allows adjusting settings like shutter speed, aperture, and ISO for variable lighting conditions. Smartphone cameras struggle in the low light of ice caves except near brightly lit entrances.

Ultra-wide and wide-angle zoom lenses in the 10-24mm range excel at ice cave photography. The expanded field of view captures expansive ice formations in cramped interiors. Popular ultrawide options like the Canon EF 11-24mm f/4L and Nikon Z 14-24mm f2.8 S Lens allow dramatic perspectives. These lenses are expensive but ideal for ice caves, so consider renting them and taking them with you for your Iceland trip. Wider maximum apertures around f/2.8 allow handheld shooting in dim lighting.

Fast prime lenses like 24mm or 35mm f/1.4 models also work well, providing a lightweight option for handheld shots. Their wide apertures offer creative potential like selective focus on ice textures. A fast prime lens also suits portraits in the ice caves with blurred backgrounds.

Telephoto zoom lenses isolate details in the ice like bubbles and mineral patterns. A macro lens captures abstract textures in intimate detail.

Shooting Techniques

Upon entering an ice cave, allow time for your eyes to adjust to the low light levels. This will make it easier to compose shots and judge focus.

Manually focusing the lens often works better than autofocus in dim cave interiors. Enable your camera’s live view mode, then magnify the screen to fine-tune focus on the icy features. Carry a small torch to illuminate focus points.

Check your camera’s LCD brightness and lower it significantly to get a more accurate preview of the exposure. The screen can look brighter than the actual scene. Refer to the histogram display for optimal exposure rather than the LCD image.

Set your camera to aperture priority mode and select narrow apertures between f/8 and f/11 to maximize depth of field and sharpness across cave features and walls. However, open up to wider apertures like f/2.8 when composing close-up shots of ice textures to creatively blur the background.

Choose low ISO settings like ISO 100 or 200 when shooting on a tripod for high resolution and minimal noise. For handheld shots, increase the ISO to allow faster shutter speeds before image quality degrades too far.

If you are shooting near the entrance with the cave and the sky outside the cave it is worth considering bracketing exposures or merging shots in post-processing to make the most of the high dynamic range of both dark and bright regions. HDR combats the extreme contrast between cave entrances and interiors.

Composition Ideas

Carefully compose shots using leading lines, patterns, icy textures, and foreground elements like pools or cascades to direct the eye and add interest. Take time to find the perfect pieces of ice, colour patterns or rocks on the floor of the cave. The curves and lines in the ice and be used as leading lines as can any waterfalls or rivers flowing through the caves.

You can also include people for scale but position them carefully so that they add to the composition. There is no point in including a person if they are in the wrong place. You can also consider shooting silhouettes against entrances or translucent ice. Lead the eye through curves and lines in the ice. Use cascading water or frost for foreground interest. Focus on the stunning ice.

Protecting your Gear

The caves are damp and cold and can damage your camera. This is especially the case if you are visiting Katla in the summer months when there is some melt. At any time of the year, the caves will be cold and this can make batteries lose charge rapidly. Always make sure batteries are tucked away in your pockets to keep them warm and have plenty of spares.

The caves are incredibly slippery and if like me you tend to be all over the place, then make sure you protect your camera. Keep it in a camera bag for as long as possible, set it up and then try to stay in one small area. Moving around can lead to trips and slips with your camera coming off worse.

Summary of Ice Cave Photography

• Keep your camera out while walking to the ice cave. The landscape is stunning and the super jeeps can make for a good foreground.
• Take time to explore the cave before starting to take photographs. Your time is limited and you need to figure out what you want to have in an image before you start. As the caves change year to year, there is no way to know what you will find when you get there.
• A wide-angle lens like this 16-35mm lens (see details and prices HERE) is ideal for an ice cave or an ultra-wide angle lens like this 14mm f/2.8 (check prices) for the darker caves is ideal. try to include the roof of the cave as this is where the best light textures and patterns can be seen.
• On wide-angle images including other visitors and photographers will provide a sense of scale and context.
• If autofocus is causing problems then focus manually. The light levels and the reflections from the smooth walls can cause problems for your camera.
• A tripod is useful. Light levels can be lower than you think and when combined with the slippery surfaces within the cave it is much better to have your camera secured on a tripod. The travel tripod by Three-Legged Thing is small and compact and provides good stability.
• Try to use a narrow aperture somewhere between f/8 and f/11, but don’t be afraid to drop to f/4 in a darker area of the cave. By using a narrower aperture a greater depth of field will be achieved.
• Keep the ISO between 100 and 400 to reduce noise. Using a tripod will allow you to use a lower ISO.
• Shutter speed is less of a consideration as you will be using a tripod. You need to ensure that the highlights and shadows are all exposed correctly using the histogram.
• If you are shooting towards the cave entrance you may need to go into bracket mode or the HDR function in your camera. This means that you will have a number of images at different exposures that can be blended together to give a correctly exposed photograph.
• While it is good to experiment with torches and lights, the natural beauty of the ice caves is best photographed using the natural ambient light in the cave.
