How to Successfully and Safely Photograph Lightning

Light Across the Pasture

Well we finally got some lightning (and a little rain) over in this part of the state last night. Here is an image I took last night during the storm. One of my most favorite subjects in photography, lightning, always makes for a nice dramatic nature image. It is so hard to get it just right, and it is nature at its most glorious.

How to Successfully Photography Lightning

Safety – you don’t actually want to get struck. If you can be in a protected area, best to not be holding a tall metal tripod during a storm, you might as well go play golf at the same time.  I list this first because it is the most important thing to keep in mind.  When you feel the static charge in the air on your skin, time to head for cover, quickly.  Know which way the storm is moving so you can take action ahead of getting yourself in trouble.

If possible, try to photography lightning from inside a protected area like a house or a car.  This is almost always not possible, but when it is, it gives you a little extra edge to be able to stick around a little longer.  this image above was taken from inside my house on the second floor out of an opened window.  I was protected from the rain and could quickly take cover in the room if the lightning got to close.

Equipment Needed for Lightning Photography

Camera – you need a camera that can do an open shutter exposure. This is usually called a “bulb” setting, where you can depress the shutter release and leave it open for an undetermined amount of time.  This usually means an SLR camera body, film or digital, that you can control the manual setting and change the shutter to “b”.  This is needed just because you rarely are going to know the exact time lightning will strike, but you can probably catch it within a few seconds.  The flash of lightning only lasts a split second, so having an open shutter is pretty much a must unless you have a lightning trip device.

I have used many many camera bodies over the years.  Right now, I am using a Nikon D300 and a Nikon D700 digital SLR, but you can get a nice DSLR now like the Nikon D40, D60, or D80 that won’t cost you an arm and a leg (sorry I know there are also many good Canon bodies as well, I am just not familiar with them).  The point is, any digital SLR will do, even an older film SLR will work great.  I took many lightning images with my old Nikon N70 and N90s film bodies.  The image above was shot with a Nikon D100 which you can now buy used for around $200-$250.

Lenses – You can choose just about any lens and get some results.  I prefer to use something around a 50-70mm lens, wide enough to get a big enough area to actually have a chance to capture the lightning and tight enough to see the lightning when it occurs.  Use to wide an angle the lightning will look pretty small in the frame, use to close a zoom and you reduce your chances of capturing the lightning when it occurs.  If this is a particularly active electric storm, a zoom might work if you know right where to place the camera.  The lens I used for the image above was a consumer lens, a 24-120mm zoom (non VR) taken at the 24mm focal length.

Tripod – A sturdy tripod is pretty much a must.  Not a plastic one or flimsy video camera one, but a heavy metal tripod that you hate lugging around with you.  If you don’t have a sturdy tripod, you can use something like the hood of a car, a window frame or ledge, a rock or stump, anything you can set your camera on to take away the effects of hand holding a long exposure.  At one point I had a very nice carbon fiber tripod (which cost me about $1,500 USD) but it was sold when I didn’t get much use out of it, and I returned to using my old heavy metal Bogen (now also called Manfrotto) tripod (retails for about $200-$300) which works great.

A Remote Shutter Release – this is something that is also pretty much a needed item.  These are not expensive items if you already have a digital SLR camera body.  They attach to the camera on a port usually in the front of a modern DSLR.  I use a pretty fancy one called the Nikon MC-20 which costs about $60 now (I paid about $130 for mine years ago), but you don’t need one like that, any $5-$10 remote trigger device will work.

Know a Little About Weather, Storms, and Which Way They are Moving

You probably want to try to get the lightning that will show up prior to the rain. This is not always possible, but it is hard to photograph during the rain storm that follows a frontal line.  There are many times when you can see the lightning well before the storm arrives.  Once you start to see it, and you can determine which direction the storm is moving, try to position yourself (it that is possible at all) where you are ahead of the storm front and can pack everything away once it arrives.

You don’t have to be a weather expert, just try to look at the clouds, see which way they are moving and try to adjust your location and distance accordingly.

The Color and Brightness of Lightning – Lightning actually comes in a variety of colors.  Each photograph I have taken always comes out with a different color, because the intensity and actually the kelvin temperature of the lightning varies greatly from bolt to bolt when you are shooting.  The cloud to ground lightning and cloud to cloud lightning is most likely going to be your subject, so once you have taken the photo, review the color in your edit process and make adjustments to the proper color you want to achieve accordingly.

Techniques for Shooting Lightning: Exposure, Shutter, ISO, Aperture and White Balance

Technique – the most common way to photograph lightning is to use a shutter release. Open the shutter for a few seconds and wait until you see some light. Then close the shutter. Do this over and over and over and hope that you actually get a bolt in the photo. You will want to use a wide lens to get as much coverage of the sky as possible. Usually once you see some light it will blow out the image if you leave the shutter open any longer, so just a few bolts at a time unless it is really dark. The object would be to try and get several bolts in one exposure. This is not as easy as it sounds, but makes for a great shot. If you try this, think safety first, nothing else.

Exposure – as indicated above, you want to use your shutter release to open the exposure in a few second intervals at a time.  This will be different with each situation because the proximity to the storm, intensity, pollution, ambient light in the area, all effect the exposure.  If you are shooting just as the sun goes down or there is still some light in the sky, a shorter shutter speed (or higher aperture combination) will be needed to reduce the background visibility.  I like to try for anywhere around 3-30 seconds on my exposures.  30 seconds is usually a bit long especially if you are in a big city with a lot of ambient light, but test it out and see what works best.

Aperture – you should already know the correlation of aperture and exposure, so if you are going to want to use a long long shutter speed, use a large aperture like f/2.8-f/5.6 and if you want something around 3-7 seconds, I would choose to stop down a bit more to something like f/8-f/11.  It also depends on how far away the lightning is and how much light you need in the exposure.  Remember, lightning is VERY bright, so you will burn out the image quickly with just the lightning bolt if you aren’t careful.

ISO Speed - I am writing this assuming we are using a digital SLR camera body.  If you are using film, usually an ISO-100 speed film will work.  I have used Fuji Velvia 50 with lightning photography before and did get some good results as well.  For digital SLR cameras, we manually set the ISO speed which is the third factor in determining exposure.  I like to use the ISO-200 setting to get the highest resolution I can get.  But you can use anything from ISO-100 to ISO-800 or more depending on the proximity of the lightning and your exposure settings.  The closer the lightning, the lower the ISO speed I would use.

White Balance – white balance on cameras today is something a little more tricky.  I almost always use the auto white balance setting just because no other pre-set or kelvin setting seems to work because each lightning bolt or strike is different.  I have used the cloudy or shade white balance and had good results with it, but I never know what I am going to get, and the auto setting isn’t any better than anything else.  It is getting better with the newer digital SLR camera bodies, but for lightning is still isn’t quite there yet.  If you are shooting your images in RAW file formats you can always look at each white balance setting in post process editing and see which one you like best.  If you don’t do any post process editing, that is fine to, the results you can get from the straight jpg file will usually look great too.

Image Data Specifics

I decided to just go ahead and copy the exact camera settings from the image above.  I love seeing data from different shots, so listed below is a copy of the exact settings I used to take the image above.  Keep in mind, all situations are going to be different and no two lightning shots are going to work with the exact settings below.  You will have to adjust everything for your situation, but you can see what I used in this image.

This image was one that turned out ok. I took probably 100 within about 10 minutes that did not. It is not an exact science by any means.

Have Fun and Don’t Get Frustrated

This is almost impossible with photography sometimes.  Don’t get frustrated with your results.  After all, photography is supposed to be fun (I think) so try to have a good time, stay safe, and shoot a lot of frames.  If you are shooting with a digital SLR you have the luxury of just shooting away and deleting files later.  I may shoot 200-300 frames before actually capturing one image.  I may shoot for an hour and not get anything.  This isn’t a flower that you have in front of you, it is something very unpredictable, so just have some patience and try again and again to get something you like.  The first lightning images I took were scarce tiny little blips of light in the sky, to which my wife said, “what is that?”.  So just keep trying and you will get some good results.

North Clear Creek Falls Colorado Long Exposure

This image was taken way way down in the river bottom. It is quite a hike down to the river and most shots are normally taken from the parking lot at the very top of the falls. This is North Clear Creek Falls in the Colorado Rio Grande National Forest, just a short drive away from Creede or Lake City Colorado.

There is also a South Clear Creek Falls and it is a little smaller and farther away down the river. I really like South Clear Creek Falls myself, it is away from the road and harder to get to, but very peaceful.  If you ever have an opportunity to photograph North Clear Cree Falls I would recommend getting there even before sunrise to put some color on the rocks and to give yourself a chance to hike down before the sun is in full blaze.

A tripod is almost a requirement for this one unless you can find a level enough rock to place your camera, without something like that you will not be able to get the flowing milky water as seen above.

  • Body – Nikon n90s
  • Lens – Nikon 24-120mm
  • Film – Fuji Velvia 50

How to Improve the Quality of Your Product Photos

How much importance do you put on using high quality images for your products and services? You have heard the saying, image sells? Well, you can increase your sales by using professional looking images. Over several articles, I am going to examine some ways we can improve the images we use to promote our products and services.

This particular article is geared more to the ecommerce side of things where you would need to use an image for product based sales.

Producing high quality images does not have to be expensive, and it can be done just about anywhere you run your business, but the finished product also reflects on your business, blog, or website, so you want to put forth the best images you can produce.

Importance of High Quality Images

I have been a photographer for about 15 years now, so one thing I always pay attention to on my own ecommerce sites is the quality of the images I use. But, you don’t have to be a great photographer to get good results. Below I will look at some simple steps you can take to improve the quality of the images you are using on your website, blog, or ecommerce site.

There is a great correlation to the quality of images you use and the ASP’s (average sales price) you achieve, or even the traffic you generate. It is easy to gage. Just put up some run of the mill (or bad) images and see what stats you get on sales, then put up a great image of the same product and see what changes.

Most people don’t want to take this approach of course, they already use the best images they have, so we should really just be trying to improve on those images, but good images draw a person into the site, they hold attention, and can also repel.

Some Photography Basics

Photography is a method of allowing light to draw on a medium to reproduce something you see. There are of course a few basic things you will need. You need a camera. A digital cameras are not too expensive now, but if you can, I would recommend getting an inexpensive SLR (single lens reflex) camera over a point and shoot type camera. The image quality will be better and you will have more options if you want to go beyond the basics.

Nikon has several digital SLR cameras for under $500, the D40 is one, and B&H Photo is a good reputable online camera dealer with good prices. I have ordered from them for years and their prices are very competitive. Another good basic piece of equipment to have is a tripod, especially for product images. The slightest movement will create a far less sharp image and if you start with a poor original you end up with a poor finished product as well. If you buy only one other item outside the camera, make sure it is a tripod.

Some Quick Tip Basics

I will expand on each of these ideas in later posts, but some things that you should remember when trying to improve on the image quality for your products.

Light on the Subject Please

You can’t have a good image without good light. Pay close attention to the light and try to use natural light, either by taking the image near a window that has some reflected light (not direct sunlight), or use a flash. The light is what makes an image, so using a light tent (more about this later) will produce a professional looking image with no background to worry about.

You can make a simple light tent out of a one gallon milk jug that works great. Cut out the bottom to place over the image and the top to place the camera lens. Then use some shop lights or other lighting sources to cast an even soft light all around the product.

Backgrounds Can Be Distracting

You don’t want a busy background on a product image. You want a clean, preferably solid color background with some good contrasting color. Try to illuminate the background as much as possible. Anything that shows other than a solid color is going to take away from the subject. You can use a simple cardboard sheet like you used in grammar school. They come in several colors and you can get them almost anywhere.

Use a clean background for image quality

Use a color for the background that is a contrasting color to the subject matter. For the image above, I used a white liner that came with the Swarovski cyrstals I was photographing. It made a nice background, and also had the company name imprinted on the paper, which was faintly visible in the shots I used for the website.

If you are taking a photo of a book with a dark blue cover, don’t use a black background, use a white background. You want your subject to jump off the screen when someone looks at it.

Proximity So You Can See

Get close. Then get closer. You want to be as close to the subject matter as possible. This is for some obvious reasons but when you are editing an image on the computer, the closer you get, the higher the image quality is going to be if you have to crop the image at all. The smaller the subject matter is on the film plane, the smaller it will be and get as you crop the image down in size.

If your camera takes a 6 mp image size, you will have an image area of something like 3000 px wide by 2000 px tall. If you take the subject in full then you have a subject that is about 3000px wide. If you take the image from a distance, it will be smaller on the file, more like 500px to 600px. When you are editing the image, you want to work with the biggest image possible.

Close up macro

In the image above, I was trying to show how to measure the size of a crystal using a caliper. It was important to get in real close to the subject matter to be able to show a clear and clean image of a subject that was only 10mm’s tall. I used a specialty lens called a macro lens to do this close up.

Each camera lens will have a minimum focus distance. This is as close as you can get to a subject matter and still have it render in full focus, find this and get as close as you can. Get in close and your image quality will be greatly improved.

Editing is an Important Step

I am only going to touch on editing briefly in this post, but this is an important step in producing a high quality image. You probably can not just take the image from your camera to the website and have it look the best that it can look. You will need to adjust and fine tune the image in some image editing software. If you can learn how to use Photoshop I would highly recommend using this program to edit your images. It is what the pros use, for good reason.

Don’t go overboard on the editing. You want to crop out the edges that are just blank space. Make sure the subject fills the entire image, adjust the levels (more about this later) and then save the file. You will want to save your final image in a form easy to use on the Internet and stick with it. A .jpg, .gif, or .png are all good file formats to use. A .png will produce a small file size with good image quality. If possible, start with a RAW image on your camera, then save it to a compressed format.

Coming Up

Coming up I will go a little more in depth about these topics discussed here and more specific how to details. If you have specific questions please post them below and I will be more than happy to answer them.

I did find some other good blog posts on the subject of image quality, like Taking Better Pictures by Lumberjocks, Ten Tasty Tips for Photographing Your Food, 5 Tips for Taking Better Photos of Landmarks and eBay’s Photo tutorial, but there wasn’t a whole lot of information out there about the subject as it pertains to blogs and ecommerce, so I will try to continue this series for those who are interested.
