How to Photograph the 12 August 2026 Solar Eclipse: A Golden-Hour Guide

On the evening of Wednesday 12 August 2026, the Moon's shadow crosses eastern Greenland, western Iceland and northern Spain. Everywhere else in western Europe gets a deep partial eclipse instead. Almost every guide you will read tells you the same thing: buy a solar filter, mount a long lens, fill the frame with the Sun. That advice is fine if you are standing in Iceland at teatime. It is close to useless in Britain and Ireland, because here the eclipse is not a midday event at all. It happens in the last two hours before sunset, with the Sun in the west and low, and the final twenty minutes of it land inside golden hour. The Sun's height, not your focal length, is the number that decides what you can photograph.

What time the eclipse starts where you are, and how high the Sun will be

Contact times below come from the Royal Observatory Greenwich. The Sun altitudes and sunset times are ones I calculated for each city using the standard NOAA solar position algorithm, because nobody publishes them and they are the numbers that actually govern your composition. All times are BST.

Three things fall out of that table. First, the Sun sits between 274° and 281° at maximum, which is due west to a shade north of it. You need a clear west horizon, and in a city that is a real constraint rather than a detail. Second, in London the eclipse ends with the Sun at 3°, roughly the height of a rooftop two streets away. Third, golden hour proper (Sun below 6°) begins around 19:43 in London and 20:04 in Edinburgh, so the closing act of the eclipse and the best light of the day are the same event. If you have never thought about how much the Sun's height changes a scene, the golden hour guide covers the underlying behaviour.

Why a 90% eclipse will not look like dusk

This is the expectation to correct before the day, because it decides whether you spend the evening disappointed. The Royal Observatory puts coverage at about 90% in London, 94% in Pembrokeshire, 95% around Truro and roughly 97.5% at the south-western tip of Ireland, and states plainly that the further south-west you go, the more you get.

Ninety per cent sounds like near-darkness. It is not. Block 90% of the Sun and you still have 10% of the light, which is about 3⅓ stops down: the difference between open sun and light overcast. At Truro's 95% you are around 4⅓ stops down, and at 97.5% in south-west Ireland roughly 5⅓. In practice the loss is a little greater than those figures suggest, because the sliver of Sun left uncovered is the limb, and the Sun's edge is dimmer than its centre.

Your eyes will hide most of that from you. Pupils dilate as the light falls, and the change happens slowly enough that vision keeps pace. Astronomers generally put the threshold for noticing a genuine change in the quality of daylight at around 95% coverage, which is a concrete argument for driving south-west if you can: Cornwall and west Wales cross into the range where the light goes strange, and the Home Counties largely do not. Your camera, meanwhile, records the whole thing faithfully, which is the point.

What you should look for is not darkness but wrongness. Colour cools. Contrast goes odd. Shadows sharpen, because a crescent Sun is a narrower light source across one axis than a disc, and narrower sources cast crisper edges. Set a manual white balance early in the evening and leave it alone, or auto white balance will quietly correct away the one effect worth capturing.

Eye and gear safety, which is the one part of this that is not negotiable

A 90% eclipsed Sun is still thousands of times too bright to look at. There is no partial phase during which staring at it is safe, and the low Sun makes it worse rather than better, because it feels comfortable enough to look at and is not.

• Eclipse glasses must be marked ISO 12312-2. Sunglasses, welding glass below shade 12, exposed film and smoked glass are all useless here.
• A solar filter goes on the front of the lens, never between lens and eye. A filter that screws in behind the optics receives concentrated sunlight and can fail while you are looking through it.
• Never point an optical viewfinder at the unfiltered Sun. Use live view on the rear screen for framing.
• Phones and cameras need the correct equipment. NASA says eclipse glasses and handheld viewers must not be used with cameras. Use a purpose-made solar filter secured over the front of the camera or phone optics, seek expert advice for the device, and follow NASA's current eclipse safety guidance.
• The filter comes off only during totality, and only if you are inside the narrow path. Nobody in Britain or Ireland removes anything at any point.

Tape the filter on. A gust that lifts a filter off a lens at 19:10 is an expensive, avoidable event.

Four photographs worth making on 12 August

Ranked by how likely you are to come home with something good, which is close to the inverse of how much gear each one needs.

1. Crescents on the ground, through the trees

This is the best photograph most people can make on the day, it needs no filter, and a phone does it as well as a camera. Gaps between overlapping leaves act as pinholes, projecting an image of the Sun onto whatever is underneath. Normally those projections are the round dapples you have seen a thousand times without registering them. During a partial eclipse every single one becomes a crescent.

Find a leafy tree with a light-coloured surface beneath it: a pavement, a pale wall, a path, a white sheet you brought. Shoot straight down, get close, and expose for the bright crescents rather than the shadow. The effect is strongest near maximum and the crescents sharpen as coverage deepens, because a smaller effective aperture in the leaf canopy makes a crisper projection. If there is no tree, a colander held a metre above the pavement does exactly the same job.

2. The eclipsed Sun inside a landscape

With the Sun at 10 to 15 degrees, you can put it in the same frame as a skyline, a ridge, a pier or a church tower at a sane focal length. That is unusual: for most eclipses the Sun is too high to include anything terrestrial without a fisheye and a lot of regret. Pick your foreground now, not on the night, and pick it west-facing with the horizon dropping to 3 degrees or lower. Coasts, estuaries, reservoirs, hill edges and long straight streets aligned roughly east to west all work. Scouting this in advance is most of the job, and the spot-finding method applies directly.

3. The filtered close-up

The classic frame: a black sky and an orange crescent. It needs 300mm or more on full frame to be worth doing, a certified solar filter, and a tripod. It is also the shot everyone else will have, and it tells you nothing about where you were.

4. People looking up

Rows of faces in cardboard eclipse glasses, lit by very odd light, is the frame that dates the picture and carries the feeling. Expose for the faces, let the sky blow, and shoot it at maximum when the light is at its strangest.

Settings that actually work

Two completely different exposure problems on the same evening, so decide which photograph you are making before you set the camera.

If you only have your phone: shoot the ground, not the sky. Point it down at the crescents, tap to focus on a bright one, then drag the exposure slider down two notches so the crescent shapes hold instead of merging into white. If you want to photograph the Sun itself, use a purpose-made solar filter designed for the phone and secured over the front of every active camera lens; do not improvise with eclipse glasses. Shoot RAW if your phone offers it, because the colour shift in the last half hour is worth recovering later. A planning app that shows you exactly where the Sun will sit at 19:12 is worth more than any accessory here; LightScout can provide calculated sun-position context and a suggested window for a chosen location; confirm eclipse planning with an authoritative source, and the iPhone apps guide covers the alternatives honestly.

If you are inside the path of totality

Different event, different rules. Iceland gets totality in the late afternoon with the Sun around 25 degrees up, which is comfortable and gives you sky to work with. Northern Spain gets a shorter totality with the Sun very low, in some places only a few degrees above the horizon, which is spectacular and unforgiving in equal measure: a single ridge or building in the wrong place removes the entire event. Guides for the Spanish path cities are up at Oviedo, Burgos, León, Zaragoza and Mallorca, and the full where-to-go comparison, including the clear-sky trade-off between Iceland and Spain, is in this month's where-to-shoot issue.

One rule matters more than all the settings: the filter comes off at second contact and goes back on before third contact, and you rehearse that at home until you can do it without looking. Totality on the Spanish mainland runs from about 85 seconds at Zaragoza to about 110 seconds around Oviedo. That is not enough time to solve a problem you could have solved in your kitchen.

The same night: the Perseids peak with no Moon at all

The eclipse ends around 20:05 and the sky is properly dark a couple of hours later, and on this particular night that matters. New moon falls at 17:37 UTC on 12 August, within an hour of the eclipse, which is not a coincidence: a solar eclipse can only happen at new moon. The Perseids peak at around 14:53 UTC on 13 August, which is daylight in Europe, so the two useful nights are 12/13 August and 13/14 August, and both of them are moonless. That combination is rare enough to be worth rearranging a week for.

Treat the quoted hourly rates with suspicion. Those numbers assume a perfectly dark sky with the radiant directly overhead, and what you actually see from a British field is a fraction of it. Rates climb after midnight as your side of the planet turns into the debris stream, so the hours before dawn beat the hours after dusk.

Settings: widest lens you own, aperture wide open, ISO 3200, 15 to 20 seconds, manual focus on a bright star using magnified live view. Point about 40 degrees away from the radiant rather than at it, so meteors cross the frame with visible length instead of appearing head-on as dots. Then leave the camera running on an intervalometer and actually watch the sky. The Scottish Highlands are the most reliable dark sky in Britain for this.

Your plan for 12 August

Nine days out, the work that matters is logistical.

1. Buy ISO 12312-2 glasses this week. They sell out in the final few days before every eclipse, and the ones still available then are the ones you should trust least.
2. Find a west-facing spot with the horizon below 3 degrees and stand in it at the same time on an evening beforehand. Same date-adjacent conditions, no eclipse, no pressure. You will discover the tree you had not noticed.
3. Decide which single photograph you are making and set up for that one. Trying to shoot the filtered close-up, the landscape and the crescents in the same 110 minutes is how people get none of them.
4. Check the forecast on the 10th, and be willing to drive. August in Britain gives you a genuine chance of solid cloud, and moving 60 miles is often the difference. South-west also buys you deeper coverage.
5. Plan the night. If you are staying out for the Perseids, sort the layers, the flask and the red torch in daylight.

And if you get clouded out entirely: the light still changes, the crescents still project through gaps in the cloud edge on occasion, and the next total eclipse to cross Spain arrives on 2 August 2027, running over four and a half minutes around Tarifa and the Strait of Gibraltar, with the Sun far higher in the sky. This one is the awkward, low, golden one. That is precisely what makes it photographable in a way the textbook eclipse is not.
