Photographing the 2015 solar eclipse

Two weeks from today, on Friday 20th March 2015, the UK will experience its biggest solar eclipse since 1999. There won't be another one as good as this here until August 2026. So let's think about photographing it!

What's happening, when, where?


This table shows when the eclipse is happening, and how much of the sun will be eclipsed at maximum, at a number of location around the UK. You'll see that, the further north and west you go, the better the eclipse. Unfortunately, nowhere in the UK will experience totality. For that, you'd need to go to the Faroes or Svalbard.

You can get predictions for any location you like on NASA's incredible eclipse website, here:

What kind of lens do you need?


In short - a big one. The biggest one you can lay your hands on, and then a bit bigger.  The sun is so bright, it's easy to overlook the fact that it's actually quite small.  Here's a simulation of what you can expect with various lenses of different focal lengths.


How do you photograph the sun?


You need a very, VERY dark neutral density (ND) filter. NEVER look directly at the sun through a camera lens. Remember, the sun might be 90% eclipsed, but the bits that aren't eclipsed are just as bright as usual, and that can really damage your eyes.

Trouble is, the terminology used to describe filters can be confusing, and manufacturers and retailers aren't consistent. There are three different ways of describing the strength of a filter which are in common use:

  • The multiplier for the exposure
  • The number of stops effect on the exposure (every stop is a doubling)
  • The multiplier for the exposure expressed as a power of 10.

So for example a "3x" filter could mean that it makes your exposure 3 times as long, or it could mean that it increases your exposure by 3 stops (8 times as long). Similarly, a filter described as "ND3" could increase your exposure by 3 stops (8 times as long) or by a factor of 10^3 (1000 times as long).

Here's a quick reference, based on these three different scales:


It's VITAL to understand what any given filter is actually doing, before you put it between your eye and the sun. If in doubt, ask and ask again. If still in doubt, don't do it.

But anyway, now we understand what filters do, how strong a filter do we need?

In general, you probably want 12 stops or better. The gold standard for specialist solar filters is Baader Astrosolar safety filmhttp://astrosolar.com/en/ - and they make it in two flavours. ND3.8 (12.6 stops) is designed for photography, and ND5.0 (16.6 stops) is recommended for visual observation. If you put a 10-stop filter, or a filter made of ND3.8 film, on the front of the lens and look through the camera wearing dark glasses, you'll probably be OK - but don't blame me if it ends in tears.

You can buy strong ND filters, but they're quire expensive. For example a 10-stop screw-in filter, in the commonly used 77mm size, costs around £80-£120. If you have a square filter holder, a 10-stop square filter costs about the same. Alternatively you can buy Baader film for about £20 per sheet and make your own filter - there are plenty of instructions out there on the internet.  Or some people would even advocate using welder's glass, which is very cheap, and can be very dark - but if you do, make sure you test its strength first.

Apart from getting the right lens and the right filter, photographing the eclipse is going to be quite easy. You won't need a tripod - unless your lens is too heavy to hand hold! - because, even with a strong filter, you'll be getting very fast shutter speeds. For example, the other day I did some tests with a 13-stop filter. I was getting 1/2000th at f/16, 100 ISO.  So that's comfortably within the range of any DSLR. All you need to do is dial in a suitable aperture and/or shutter speed, focus your lens on infinity, set the camera to spot metering, point, shoot, and repeat as desired. If your filter imparts a colour cast, it's easy to fix it in Lightroom or Photoshop afterwards. Job done.

Let's do it!

Northern Lights part 3 - personal experience and conclusions

If you tuned in for parts 1 and 2 of this feature, you'll be totally up to speed with the high-ISO capabilities of your camera, and you'll have seen that in the right conditions you can get good photos of the aurora with nothing more than consumer-level DSLR equipment. If you missed them, part 1 is here and part 2 is here.

In part 3 we'll look at what can happen when the conditions aren't right - something I have experience of, unfortunately - and use this to work out what kind of equipment gives you the best chances of getting some good photos.

Iceland, December 2012

On my short trip to Iceland in 2012, we only had one night with clear skies (and no moon), but the aurora didn't show. At least, not to the naked eye. If you looked out of the corner of your eye towards the northern horizon there was a sort of glittery cloudy feel to it, but if you looked straight at it there was nothing. However, the camera proved that there was something there. This was taken using a Canon 5D (Mk I), f=18mm, ISO 3200, 30 seconds at f/2.8.


At ISO 1600 and f/4 - the limits we're assuming for consumer-grade equipment, remember - the exposure time would have had to be 2 minutes!! But that really is a sort of worst possible case. In those circumstances I'd have been quite happy to leave the camera to take a 2-minute exposure if that was the only chance I had to get something. I'd probably have taken a load of shots and overlaid them to get some star trailing, or something like that. In these dire sorts of conditions, I think your results are limited more by your imagination and your determination than by your equipment.

Norway, March 2014

In early 2014 I went to Tromsø in Norway and again the conditions weren't good. We had one night when things looked promising, but then it clouded over just as the aurora was starting to show; and we had one night when the skies eventually cleared, and we saw an aurora, but it wasn't great.

This is from the first night: Canon 6D, f=15mm, ISO 3200, 2 seconds at f/2.8. At ISO 1600 and f/4 it would have been 8 seconds, which I think would have been workable.  But you'll note that the overall illumination of the scene benefits from those clouds, which are reflecting light from some villages a couple of miles away. Without the clouds, I'd have had to use a longer exposure time or tolerate the landscape being dark and underexposed.


And these are from the second night. Both shots are with the Canon 6D, f=15mm. The first was ISO 3200, 20 seconds at f/2.8; the selfie was at ISO 5000(!!!), 15 seconds at f/2.8, and even then we had a bit of accidental help when somebody in the car park behind the camera switched on their car headlights At ISO 1600 and f/4 the exposure times would have had to be 80 seconds and about 90 seconds, which I don't think would have been workable. Certainly not for the selfie!




Observations regarding focal length

You'll have noted that all my photos were taken with ultra wide lenses with focal lengths of 15mm to 18mm on full-frame (FX) DSLRs. That's the equivalent of about 10mm on crop-sensor (DX) cameras. My personal favourite is the Canon 15mm f/2.8 fisheye, which is sadly no longer manufactured but is a super lens for the Northern Lights. (The Nikon equivalent is the Nikon 16mm f/2.8 fisheye. There are also 10mm fisheyes available for crop-sensor DSLRs.)

Could you get away with a less wide lens? Yes, you could. For example I've illustrated below how these four photos could be cropped to stimulate what you'd get with a 24mm lens (15-16mm on DX). I think they're still quite acceptable from a compositional point of view. Acceptable, but I think definitely not ideal. Until I saw a half-decent aurora in Tromsø I really had no appreciation of how much of the sky they could occupy.


 Interestingly, a 24mm focal length also allows you to use an f/1.4 lens. (For example, the Canon EF 24mm f/1.4 L II USM or the Nikon AF-S 24mm f/1.4 G ED.) I've got to admit that I'm really not sure how valuable this would be, though. On the one hand, 24mm really isn't very wide at all unless you're using a full-frame (FX) DSLR, and they can usually cope at high enough ISOs that you perhaps don't really need f/1.4. On the other hand, f/1.4 is brilliantly fast and it might well come in handy - especially if you want to keep the ISO down in order to make a big print. (Remember how the ISO capability of your camera depends on what you want to do with the image?) I guess at the end of the day having a 24mm f/1.4 lens in your bag gives you options that you wouldn't have otherwise, and that can't be a bad thing.

Conclusions and recommendations

You'll have noticed that there was a sort of common theme to my aurora photos. In the three new-moon cloudless-sky faint-aurora photos, I've relied on the fact that I could shoot at ISO 3200 or above, and that I've had an f/2.8 lens. If I had been limited to ISO 1600 and f/4 - our notional consumer-grade equipment - the exposure times for these three photos would have been in the range of 80 to 120 seconds. That's not good.

So, what have we learned?
  • You want a really wide angle lens. Fast is good but wide is essential. My four pictures here were taken with focal lengths of 15-18mm. (On a crop-sensor DSLR that's 10-12mm.) 
  • If you have moonlight and a bright aurora, you'll be fine with a consumer-grade DSLR and a wide-angle lens. But if you don't ... you might not be.
If you don't already own a full-frame camera and an ultra-wide full-frame lens, I'm not going to say that you should buy or hire one for your Northern Lights trip, for two reasons. Firstly, one very important consideration is that operating a camera in the dark really isn't easy, and you need to know your way around the controls. It could be that you'd be happier with a camera that you know well, rather than one which is theoretically superior but unfamiliar. Or perhaps not. It depends what sort of person you are, I guess, and how easily you pick these sorts of things up. And secondly, because you might not need it. If you get a good light show and good moonlight, you can get decent results with a lower-spec camera and lens. Or if it's cloudy every night, it doesn't matter what camera you've got!

But it's clear, I think, that there are definitely some conditions in which consumer-grade kit would struggle, and something like a Canon 6D / Nikon D600 (or better!) and an f/2.8 lens would cope better. At the end of the day it's for you to decide how likely you think that is, how important it is to you, and whether it's worth the money.

Northern Lights part 2 - Some practical considerations



If you tuned in for part 1 of this feature, you'll appreciate that it's important to understand how high you can push the ISO of your camera. Hopefully you'll have tested your camera to see how it performs. If you missed it, part 1 is here.

So, now you know what your camera can do. How are you going to take advantage of that? What's it actually like photographing the Northern Lights?

Well, before we talk about anything else, the first thing to remember is that it's probably going to be COLD. You can look at the temperature records for popular gateway destinations like Tromsø and Reykjavik and the Lofotens (WeatherSpark is a great source) and see that they have average overnight temperatures in the winter of around -5°C to -10°C. But on any given night it can be much colder. And if you venture inland, away from the coast, it can be an awful lot colder. As I'm writing this, it's -32°C in northern Finland, only about 100km from Tromsø. Of course, as they say in Finland there's no such thing as bad weather, just bad clothing. So make sure you look after your vulnerable extremities, and make sure you look after your camera batteries and keep them inside your clothing whenever possible. The cold can kill them very quickly.

Apart from being cold, it's also usually quite DARK. (During the winter season, hardly a week goes by here at LensesForHire without a customer conversation along the lines of "Northern Lights ... tripod ... dark ... tripped over ... smashed.") That's why you've tested the high-ISO capability of your camera - you have, haven't you? - but even so you'll want to be shooting with as wide an aperture as you can manage. And you'll want your lens to be wide too - auroral displays often take up a very large part of the sky. Most guides to photographing the Northern Lights will tell you that you need a wide and fast lens, but they don't often help you choose between wide-and-very-fast (e.g. 24mm f/1.4) or fast-and-very-wide (e.g. 16mm f/2.8). This one will. Bear with us.

We'll see some practical illustrations in part 3 of this series, but the short version for now is that in part it depends on your camera. If you have a very modern DSLR which can happily shoot at very high ISO values, then you don't have to worry so much about "fast" and you can concentrate on "wide". With an older DSLR that's more challenged at high ISO levels, "fast" is more important. So what we'll do for the purposes of this exercise is assume you have a typical consumer DSLR setup - a camera that can cope well up to ISO 1600, and an f/4 wide angle lens - and see how you get on with that.

Anyway, it's dark. How dark? Well, that depends on whether or not the moon is out. (You can check moonrise and moonset times, and a whole lot more besides, using The Photographer's Ephemeris.)

Let's look first at the situation where the moon is out. The landscape will be illuminated by moonlight, and that pretty much defines your exposure for you.  You have to set the exposure to expose correctly for the landscape, and that's that. (A photo of the aurora with no land in it wouldn't be very satisfying. Too abstract, and no sense of scale.)

You probably know the Sunny 16 rule: in bright sunlight, at f/16, the correct exposure is the reciprocal of the ISO setting. So 1/100th of a second at ISO 100, 1/400th at ISO 400, and so on. Obviously you can use this to calculate the correct exposure time for any combination of ISO and aperture. For example let's look at your assumed limiting conditions of ISO 1600 and f/4. ISO 1600 is 4 stops more exposure than ISO 100, and f/4 is 4 stops more exposure than f/16, so you'd need your shutter speed to be 8 stops faster than 1/100th, which would be ... something which no regular camera can achieve. Obviously. Shooting at ISO 1600 and f/4 in bright sunlight would be madness.

But moonlight from the full moon is about 17-18 stops fainter than sunlight. (Reference.) Plus, I think a moonlight photo would want to be underexposed by a stop or two - you want it to look like moonlight, nor sunlight. So at ISO 1600 and f/4, you're looking at shutter speeds which are 7-9 stops more exposure than 1/100th, which is around 1½-5 seconds. That's quite workable, I would suggest.  With an ultra-wide lens, your stars will still be points of light (i.e. no visible trailing) as long as your exposure is less than 20-30 seconds. (Reference.) And if the aurora is moving, it shouldn't move too much in that sort of time.

So that's an important result.  If the moon is out, you should be fine with consumer-grade DSLR equipment like we've assumed. What you'll see by way of aurora in your photos depends, of course, on how bright it is relative to the landscape. If it's bright enough, you'll get good images.  If it's less bright, your best bet is probably to take composite images, one for the landscape and one for the sky with different exposures, and merge them later.

But around new moon the illumination is much harder to quantify - starlight, aurora, street lights or village lights perhaps, clouds, light from the moon or sun below the horizon scattered by the atmosphere, and so on. Determining the correct exposure is much more difficult and tends to be much more trial-and-error. We'll look at that, and look at some specific equipment recommendations, in part 3.

Northern Lights part 1 - Testing the high ISO capability of your camera

At this time of year lots of our clients are off in search of the Northern Lights, and that can be a demanding challenge for both your camera and your lens. It's not like taking photos in daylight, and you're often faced with having to make difficult trade-offs between aperture, shutter speed and ISO. You aperture is of course limited by your lens; you don't want the shutter speed to be too long, so that you can capture the movement of the aurora; but you don't want the ISO to be too high, in case your images are too noisy.

The difficult part of this is sometimes the ISO. How many of us know how high we can push the ISO setting on our cameras before the images start to become degraded? It's not something you can just look up on the internet, for two reasons. Firstly different people have different standards when it comes to the acceptability of noise. And secondly - as we'll see in a minute - it depends on the size at which you're viewing your photos. But fortunately it's not too hard to test for yourself.

The basic idea is that we choose a test scene and photograph it repeatedly using different ISO settings. Ideally the scene should contain a range of colours and a range of dark and light tones. You'll need to set up the camera on a tripod to ensure that each shot is framed the same. And you'll need it to be indoors, because shooting at high ISO values in sunlight is difficult - it often needs a faster shutter speed than your camera can manage.

Something like this, perhaps.


Set the camera to aperture priority, and set the lens to a middling aperture like f/5.6 or f/8 where it's going to perform well. (This test isn't about the lens.) You may as well set the camera to produce JPEGs rather than RAWs because it's quicker and we don't need to do any clever processing. And it doesn't really matter whether you have in-camera noise reduction set to on or off, but remember that your results only apply to that one situation. (You might want to try the test twice, with noise reduction on and off.)

And the procedure is really simple. Set the ISO to 100 and take the shot. Set the ISO to 200 and take the shot. (The exposure will be twice as fast, obviously.) Set the ISO to 400 and take the shot. And so on until you've reached the highest ISO value that your camera can manage.

Now all we need to do is look at the images and see where they start to get noisy. But there's an important point to remember. The closer you look at them (i.e. the higher the magnification), the more you'll see the noise.

Here's an example, using a set of images from a Canon 650D. I've cropped a section from each image from ISO 100 to ISO 6400, and put them together on this composite. This comparison is at 100% resolution - what some people call a 100% crop - because each pixel in this image corresponds to one pixel on the sensor. It looks a bit clumsy having such a big image in this blog post, but it's important to view the composite image at full size (1800 x 900 pixels) if the conclusions are going to be valid.

(Don't worry about the ISO 400 image looking a bit blurry, by the way. It looks like the tripod wasn't perfectly stable, or somebody jogged the camera. Ideally we'd have been a bit more careful. But it doesn't really matter.)


So what do we see here? Well, personally, I think that up to ISO 800 everything is fine. But there's clearly some noise at ISO 1600, and from ISO 3200 upwards it's very bad.

But, remember I said that the size at which you're viewing your photos makes a difference? This test was done at very high resolution - the full 18-megapixel image of the test scene, 5184 x 3456 pixels, would be about 4 feet / 1.3m wide at this resolution if you're reading this on a standard computer monitor. If you were to print it, you wouldn't be able to see all this detail unless you printed at A3 or larger. Most of the time, most of us don't do that.

So what happens if the image is smaller? In simple terms, the noise is reduced. Making an image smaller involves combining several pixels into one pixel, and in that process all the random noise gets averaged out.

Here's another comparison of the images taken at different ISO settings, but this time it's presented at 50% resolution. I've scaled the full test image to 50% of its original size - from 5184x3456 to 2592x1728 pixels - and then extracted the crops.



At this resolution, the full image would be about 27"x17" on a standard resolution monitor, and that isn't massively more than the kinds of monitors some of us use these days with desktop machines. You could theoretically see the individual pixels if you were to print it at 9"x6" or larger. To my eye, averaging out the noise by reducing the size of the image seems to have helped. ISO 6400 is still dreadful and ISO 3200 is still bad, but ISO 1600 isn't looking so bad.

And finally, here's a third comparison which is based on an even greater reduction in image size. This one is at 20% resolution. I've scaled the full test image to 20% of its original size - from 5184x3456 to 1037x691 pixels - and then extracted the crops. So each pixel here is constructed from a 5x5 block of pixels in the original image, and we might expect that the averaging process has done quite a lot to the noise levels.



This is more like the kind of resolution you'd use for displaying the image on the internet. To my eyes, ISO 1600 is quite acceptable at this resolution, and ISO 3200 certainly isn't too bad, though ISO 6400 is still pretty ropey.

So all in all, that gives us quit an interesting set of results:

  • you can use ISO values up to 800 without any concerns;
  • for large prints, ISO 800 is fine but ISO 1600 is questionable;
  • for small prints, or for full-screen display on a large monitor, ISO 1600 is probably acceptable;
  • for use on websites etc ISO 1600 is fine and even ISO 3200 is reasonably OK;
  • but ISO 6400 should be avoided unless you're desperate.
Remember, this is based on MY assessment as to what is or is not acceptable: you may have different standards. But you'd still get a similar pattern with graduations in it depending on the intended use of the images.

And remember also, that this is based on a Canon 650D with no in-camera noise reduction. If you'd like to know how your camera compares ... what's stopping you?

Smashing fun with filters

One of our customers recently had a bit of a mishap with a protective filter. She dropped it when she took it off to clean it:

Ouch!

Obviously you wouldn't want to put that back on the front of the lens.  But it led us to wonder what would happen if you did.  So we tried it.  In case you're interested, the lens was a Canon EF 85mm f/1.2 L II USM (we're glad she didn't drop that!!) and the camera we used was a Canon EOS 5D Mark III.  All the images below are JPEGs straight out of the camera on its default settings, with no additional processing.


Firstly, with the lens stopped down to f/10, which is about the smallest aperture most people will be using most of the time.  This is without the filter:


... and this is with the broken filter in place:


You might be  surprised by how little difference there is.  The second photo has noticeably reduced colour saturation and contrast, and that particularly affects the specular highlights on the metallic objects, but that's the main difference. The second photo also looks a little bit less sharp, but we reckon that's largely an effect of the reduced contrast. To show that, we can look at a couple of crops from the centres of the images. Firstly without the filter:


and then with the broken filter:


You can see that, despite the reduced contrast, there's still plenty of detail in the photo taken with the filter. (Remember, if you're viewing this on a standard desktop monitor, the full image would be about 4-5 feet across at this magnification!)  We reckon that, if you were to boost the contrast on the with-filter photo, and sharpen them both judiciously, you'd really struggle to tell them apart.


And then we tried the same thing with the lens wide open at f/1.2. This is taken without the filter:


and this is taken with the broken filter in place:


Again, the main difference is a loss of contrast. The shallow depth of field pretty much masks all other effects.  (Plus, the shallow depth of field makes the comparison a little bit more difficult: if you look closely at the tool kit you'll see that the second photo is focussed slightly further back than the first one. You wouldn't spot that at f/10.)


Wow. Remember, this is the filter which we used:


Some people are very sniffy about using protective filters because they degrade the image quality. Well, yes, they do.  In some other applications - for example if you're shooting into the light, or shooting at night with lots of bright point sources of light - they can have a significant effect.  But this little experiment demonstrates that, for most photography with "ordinary" subjects and "ordinary" lighting, even a totally smashed filter has surprisingly little effect. An undamaged filter would obviously have even less effect.  And dust on the front of the lens ... don't worry about it!

Some extreme equipment on our current shopping list


When we exhibited at The Photography Show at the beginning of March, we were quite surprised at the number of people who were asking us about various equipment which we don't currently stock.
