Tomorrow the sky will go dark. "So, what," we hear you ask, "that happens every night?" Oh ye of little knowledge: tomorrow, the sky will go dark in the middle of the morning.
The solar eclipse - for that is the cause of this darkness - will be visible in the UK from around 0825 to 1040, peaking at about 0930 depending on your location.
On its unending quest to usurp the Sun as the most important orb in the sky, our Moon, like your mate's brother on FIFA, is more talk than substance. The last full eclipse in Europe happened in 1999, and, with tell-tale inconsistency, the next total eclipse in the UK won't be until 2090.
This one's a partial eclipse in the UK - you'll need to go the Faroe Isles for 100% coverage - but given that the next big eclipse in the UK won't be until 2026, you definitely won't want to miss this one. Aand if you want to catch it on camera, you'd better move sharp. Fortunately, we've come up with a list of tips to help you out. Stick your batteries on charge and read on…

Safety first. Seriously. Do not look directly at the Sun, or you’ll toast your retinas and risk blindness. That’s right, kids: we’re going to talk about protection.
What you need is something that blocks out 99% of the Sun’s harmful rays. One of the best options is solar filter film, which you can put over the end of your camera lens.
It’s a super-thin shiny material that resembles the foil wrapper of a Kit Kat. We’ve gone for Baader’s AstroSolar Safety Film, but there are other brands. You should be able to find it at good camera and telescope stores, and not only will this protect your eye, but also your camera (sensors are sensitive, duh).
Failing that, you can use welder’s glass - the stuff that goes into a welder’s helmet. It should be available at DIY hardware stores, and you'll want to look for shade 14 or higher.
Whatever you do, do not use sunglasses to protect yourself - they are not nearly strong enough to protect you. The same goes for CDs and crisp packets too. Even Space Raiders.
Now for the camera. You’ll need a DSLR, because they let you attach big lenses. And we mean BIG: you just won’t get the requisite level of reach with a pocket point-and-shoot.
We’re talking at least 500mm. You don’t need to fill the frame with the sun, because what happens around it can also look great, but you don't just want the eclipse to be a tiny black dot in the distance either - otherwise it could be a seagull. Or some dust on your sensor.
Yes, big lenses are expensive, but rentals are fairly affordable. Alternatively, if you can't get your hands on one, consider getting a teleconverter, which slots between your lens and camera to give you extra reach. These are a lot cheaper and more flexible in use than a single massive lens.
It’s also worth considering what type of camera you have. APS-C cameras have crop sensors, which make the most of telephoto lenses: attach a 500mm lens and you’ll actually be getting about 800mm of reach. Micro Four Thirds give even greater distance: the equivalent of 1000mm with a 500mm lens.
Take time to set up
There’s no concrete rule about camera settings for an eclipse: they'll very much depend on what the weather is like on the day.
In the UK, that can mean anything. Your best bet? Get up a little earlier and do a dry run on an un-eclipsed sun.
Take a series of shots using every shutter speed from 1/4000 second to 1/30 second. Choose an aperture between f/8 and f/16. You can use any ISO, because the sun will give off plenty of light, but lower ISOs will give you better colours and less noise.
It’s worth bearing in mind that autofocus may not cooperate with a solar eclipse. You don’t want to get blurry images at the last minute, so tinker with manual focusing when you do your test shots.
So, you have your camera all set up. You’ve got a massive zoom, and maybe an extender on top of that. You’re ready to shoot. But your target is very small and very far away, and every tiny movement is enough to cause a blurry image. This is where your Call Of Duty skills come in: as Confuscius may or may not have said, "You must think like a sniper."
Get yourself a tripod. Sure, you can prop yourself up on a window ledge, but that won’t stop your shot being ruined by something as simple as clearing your throat. Like Dr. Grant facing a T. Rex in Jurassic Park, you want to lock down your movements as much as possible, and that means using a 'pod.
Even then, the tiniest movements could affect the sharpness of your shot. Don’t slam down your shutter button – squeeze it. Controlling your breathing helps. Don’t take a deep one and hold – imagine you're doing pilates on a Caribbean beach: breathe naturally and shoot near the end of an exhale.
If this is starting to feel a little ridiculous, just set your camera to a two-second timer. Or better still, use a remote trigger.
