Long Exposures - the step by step guide to successful long exposures

For me personally long exposure photography allows me to explore a sense of calm, a visual relaxation that matches the way I feel when I look at the landscape. But for some the technical side of this style of photography makes it incredibly frustrating and stressful.

Before we get into the technical side of LE photography and counting exposure increase on our fingers and toes, there is something that is far more important than the technical issues. It is vision, interpretation and connection with your subject.

Ansel Adams said “A great photograph is a full expression of what one feels about what is being photographed in the deepest sense and is, thereby, a true expression of what one feels about life in its entirety.”

You have to be able to connect your emotions to the landscape around you. It’s no good just shooting lots of images in the hope of getting one good one, shoot one good one that really captures how you feel and perhaps shoot a second image. If nothing else long exposure work will stop you shooting lots of images, the thing you’ll need in abundance is patience and not memory cards.

Let’s get down to business and make long exposure a simple creative exercise rather than something that seems baffling to some people because of the exposure calculations.

Here are my tips to get you shooting beautiful long exposure images.

1, the kit;

You’ll need a camera with a “B” setting in the shutter speed range plus either an electronic or screw in cable release with a lock and ideally a timer - although most Fuji cameras have built timers. You’ll need a sturdy tripod and a set of neutral density filters and some graduated neutral density filters.

The filters are the key bit of equipment that you should pay attention to, they will depend on your budget BUT and it is a big BUT, brands like Lee and Formatt Hitech are without a doubt more expensive but they are better both in manufacture, consistency of colour and density.

You can shoot long exposures on any lens, so don’t always stick a wide angle on and think it will make the best focal length for this type of work - lens choice is personal and entirely related to the subject. The lens I use most is my 35mm Fuji - equivalent to around 50mm.

2, Composition;

Many people seem to think that milky water or a blurry cloud will make up for a well-executed image, it won’t, so think about how you would normally compose your pictures and work with that, or allow yourself to start from the beginning again and use very basic compositional rules to help you. Long exposure will highlight every mistake compositionally, so make sure that all the elements you want in the frame are exactly where they should be before you press the button. The devil is in the detail and pay attention to the edges of the frame too.

3, Focus;

Obviously you need to focus your camera on the important part of the image - this is usually, with long exposure the object that will remain stationary. Once you have focused accurately turn the AF off, the reason for this is that many cameras struggle to focus with ND filters in front of the lens, remember if you can’t see through neither can the camera. Always take a moment to recheck your focus just before you slide your filter in.

4, Exposure;

This is the place most people come unstuck or wander into the world of guess work, this bit is important so let’s simplify it.

Exposure is a combination of shutter speed, aperture and ISO.

Each of these is important and each relates to and affects the other, but it doesn't have to be complicated.

Set your ISO low - 200 on our beloved Fuji X series cameras is the lowest they will go in RAW, so use that. Simple so far?

Choose an aperture that gives you the depth of field your subject demands - most people start off shooting long exposures at F22 because this will automatically give you a longer shutter speed. You can shoot LE images at any aperture, you just need to put two or three filters together to slow the shutter speed down.

The final part of the exposure triangle is shutter speed, this is the bit that can be difficult, but trust me it isn’t - I promise.

With your ISO and aperture set, alter the shutter speed until you get the correct exposure without any filters in front of the lens, use the EVF or the screen to judge when your exposure looks right. Take a test frame at that exposure - if it looks right on screen and you have clipped the highlights or shadows on the histogram your test picture will look correct too. For the sake of argument lets say that the exposure we took our test frame at was 1/4 of a second at F16 with an ISO of 200.

Now you can work out what your exposure will be with you 10 stop filter in place, you have ten fingers so you can count it out - or you can make life easy for yourself by using the exposure that comes with the filter or download an app for your phone. I use the Lee Filters App, it’s very easy, click on the filter you are using, then on the left hand wheel dial in your unfiltered exposure it will work out the exposure with your filter for you. Simple, and lets face it photography is meant to be fun not an exercise in how good you are at maths!

Using the Lee app - 1/4 second becomes 4 minutes with a 10 stop ND filter

Our new exposure is there 4 minutes at F16 ISO 200.

5, Filters;

When it comes to filters buy a system with a holder and adapter rings. Don’t buy the variable ND as you can’t accurately predict what density you are shooting through or screw-in filters as you may inadvertently alter the focus of the lens, and don’t buy cheap brands of filters because the colour of a neutral density filter is meant to be neutral not pink or green.

What filters will you need? To get you started you should buy the following; a 0.6 (2 stop) graduated ND filter, a solid 10 stop ND filter and a 3 stop ND filter.

The graduated filter will control the contrast between the sky and the land or water. The solid ND will allow you to slow down the shutter speed to give you the ethereal feel to your images.

Compose, focus and set your exposure without any filters, I always set my exposure to achieve detail in the dark shadows, I then add a graduated filter to darken the sky and finally when I have the exposure balance I want I add the solid ND filter. I then re-calculate the exposure depending on what filter I am using and shoot.

Left to right; Set your basic exposure with no filter remembering to expose for the dark areas, add a graduated filter to bring the sky back in and finally add your 10 stop filter and re calculate your exposure.

6, Shoot the image;

Before you press the button there are a couple of things to do, firstly turn the Long Exposure noise reduction off in camera - this can be found in the menu of the camera. The reason for this is because the camera records a second frame which takes as long  as your original frame to take, so a four minute exposure takes eight minutes in total - believe me you won’t want to wait the extra four minutes so turn off the Long exposure noise reduction before you start.

Attach the camera to a sturdy tripod and attach the cable release, this will avoid any shake or camera movement.

Finally check everything, you’ve focused the image, worked out your exposure, turned the AF off, attached the filters.

Now with everything in place turn the shutter speed setting to B or Bulb, this will allow you to leave the shutter open for longer than 30 seconds as long as you press and lock the button on the remote shutter release cable.

So what are you waiting for press the button, lock it and watch the timer in either the view finder or on screen, when you exposure time has been reached unlock the button the cable release and review your image.

A Fujiholics Story - Paul Sanders

Paul SandersI’ve been a professional photographer since the age of 19. My mind was made up for me at school hen the careers advisor told me I shouldn’t be a photographer - apparently it’s too competitive and I hadn’t got the right aptitude for it.

My career has been varied so far, I’ve shot glamour calendars, advertising work, wedding and hair fashion for a very well known hair stylist. But most of my photographic life has been spent as a news photographer or picture editor.

I started in news photography at a paid for weekly newspaper in Northampton and moved fairly swiftly to wards a career on Fleet Street, firstly with international wire service Reuters and by 2002 The Times. By 2004 I was made picture editor of The Times and took control of the visual content of the publication in all its various guises. I’d look through around 17-20,000 images everyday, assign photographers across the world covering everything from conflict to Royal weddings, weather features to business profiles.

By 2011 I got ill with stress related issues leading eventually to a breakdown, depression, insomnia and self harm, so by the end of 2011 I left the cut throat world of newspapers and set about shooting landscapes. I started using 5x4 Ebony cameras and 6 x 12 horseman as well as my DSLRs and to cut a long story struggled a lot, my illness didn’t help but the amount of kit I had bogged me down to the point that I pretty much stopped taking pictures.

By chance I went into the local camera shop and picked up an X-Pro1 with a 14mm lens. I decide dot get back my inspiration I’d only shoot with one camera and one lens for a bit. The joy of being free from the big bag of kit was like a breath of fresh air through my photography and my life.

So, You’re a Fujiholic?

Having used the X-Pro1 for a while, when Fuji released the X-T1 I was hooked from the moment I touched it - it reminded me of my Nikon FM2 - A camera I loved and still do, but here was this little camera that didn’t get in the way of my photography and had the looks and feel of a camera that got me started. I made the decision overnight pretty much to go Fuji. I started selling my Canon gear and acquiring Fuji lenses and some change!

Which is your favourite lens? Why?

I don’t really know because I go through phases of loving different lenses. When the 10-24 was launched I used nothing else for months. The lens I use a lot at the minute is the 50-140, but the lens that I have on my camera most is the 23mm.

The optics of all the Fuji lenses are stunning, so in truth the lens I have on the camera is my favourite.

What's next for me?

I'm trying to get gallery representation, and it’s not as easy as it might sound, so this year is about getting my work into as many fairs and exhibitions as possible.
