The Complete Light Painting Tutorial

Light painting is my favorite photography technique, but as I travel around the world meeting up with readers of Improve Photography, it's usually the thing that is toughest for new night photographers to get right.  In this article I want to share with you simple steps for creating a good light painting, and some pitfalls to avoid.

During this tutorial, I'll be showing images from a recent light painting I did in Ireland and the tips I used to make it work.

Step 1: Set up the camera

The first thing you'll need to do is get your camera on a good tripod.  Light painting without a tripod won't work because you need to keep the camera still.  Pick your composition and then lock down the ballhead so the camera won't move during the process.

Next, your camera settings.  As a very rough general rule, I'd set the shutter speed to 30 seconds (30″), the aperture to about f/5.6, and then select ISO 1600.  Obviously, those settings will depend on how bright the night is, how strong your flashlight is, etc.

I usually don't bother with a shutter release.  Just gently press the shutter button with your finger and then you'll run around shining the flashlight on the building (or whatever else you're light painting).  Go ahead and start the exposure now.

Step 2: Pick the right flashlight

Really, any flashlight can work for light painting, but I do think that if you just invest $15 or so, you can have a much easier time.  I cannot recommend this headlamp on Amazon strongly enough.

I use that headlamp for all my light paintings for a few reasons: (1) it's a neutral white light, which is far more natural looking than an incandescent bulb which is much warmer, (2) it allows you to zoom the light in and out and choose a square shaped light or a circle light, which helps to get the light only where you want it to go, (3) it's just the right brightness, (4) it takes AA batteries which is nice because I always have extras in my bag for my flash, and (5) it's really cheap.

Again, it's not like switching flashlights will suddenly make your light paintings better, but it is nice to have a good one.

Step 3: Start painting your exposures

In order to make a really good light painting, you'll probably want to make several exposures and blend them together to make a single finished image.  This will require just a little Photoshop work, but it'll be worth it.

Here are the images you'll need to make.  Keep the camera settings and composition the exact same for all the pictures:

  • First of all, make an exposure with no light painting.  We'll use this later to put on top of the other layers in Photoshop and lower the opacity so that you can make it look more natural if you got a bit too heavy-handed with the flashlight.
  • Second, take an exposure standing just a few feet to the side of the camera where you light paint everything with the flashlight with equal power.  If something is farther away from the camera, spend more time painting that spot as the light won't hit it as powerfully.  This exposure will also be used for blending in with the other exposures if you have an area that's too dark.
  • Third, you'll now take several exposures where you paint just specific areas of the frame.  To do this, you NEED to walk away from the camera and paint from different angles.  Keep your light low to the ground for exposures of the foreground so you throw texture and shadow on the ground.  If you're painting the side of a building, stand to the side of the wall and shine along the wall to pick up the flash.  If you shine directly flat on to a surface, you cut out the texture, which isn't what we want.  This step could take several frames.

The reason we do multiple exposures is that it's hard when light painting to get each shot perfectly painted the first try, so by taking multiple pictures on different areas of the frame, you get more tries to get the painting perfect.

Don't worry about your histogram too much while shooting.  It's normal for 70% of the data to be dark.  Just make sure that the area you've light painted should be about 3/4 up the way to the top on the histogram.  If you aren't getting a lump of data toward the top of the histogram, you probably need to increase your ISO.  Remember that the photo on the back of the camera looks brighter than it really is, because your eyes are adjusted to the night.  Don't go too dark!

At this point, you probably have one normal frame, one frame with fill light everywhere, and between 3 and 10 frames from painting different areas of the scene.

Step 4: Blend the photos in Photoshop

For some of you who are familiar with Photoshop, this step will be simple.  For others, this could be a bit difficult.  But don't fear, this doesn't require any advanced Photoshop trickery.

Here are the steps you'll need to know:

  • Open each of the photos you took as layers in Photoshop
  • Name each of the layers according to what area of the photo they have painted.  For example, grass layer, roof layer, front door layer, etc.
  • Rearrange the layers so the layer that has the smallest part of the frame light painted is on the top, and then the most light painted area on the bottom.  The only exception is the fill light and “no painting” exposures, which will be the top two layers, but please hide those layers for now.
  • Put a layer mask on the top visible layer and paint it all black.  Then paint white just on the small area that you want to show.  The idea here is that we only want the light painted area in each photo to show up.  The reason we do multiple exposures is that it's hard when light painting to get each shot perfectly painted the first try, so by taking multiple pictures on different areas of the frame, you get more tries to get the painting perfect.
  • Next, make the un-lightpainted photo visible on top of the stack.  Change the opacity to suit your taste.  I often find that just putting it at around 35% opacity helps to take the cool light painting and lessen the effect so that it isn't too weird or overdone.
  • Last, if there are any areas which are too dark, you can use the fill light frame with light opacity to fill them in.

Step 5: You're done!

Your light painting is done at this point.  You can now bring it into Lightroom and do any global adjustments you want to do.

The First Key to a Good Light Painting–Angles!

You'll notice in the tutorial above and the video at the top of this post that I mentioned several times how important it is to light paint from different angles.

If you stand behind the camera to do your light painting (for everything except the fill light shot), you're definitely doing it wrong.  If you stand behind the camera, you're basically just blasting the landscape with on-camera flash.  That wall of light from the same angle as the camera will fill in all the shadows so you'll miss out on the moody rich shadows.

Keeping the flashlight low to the ground and sweeping across the ground will create moody, rich shadows.  If you just stand up high and blast down on the ground, you fill in the shadows and miss out on a great moody shadow.  The image above of the grass illustrates this point quite nicely.

The Second Key to a Good Light Painting–Softness of the light!

When you do flash photography, you generally wouldn't want to just shoot with bare flash.  Generally, you want to use a light modifier to spread out the light–thus making it softer.  The larger the light source, the softer the light is.  When I say softness, I don't mean that it's dimmer, but that it transitions from highlight to shadow with a gradual gradient.

If you haven't learned much about flash and light modifiers, PLEASE consider checking out my Lighting in a Flash video tutorial.  It's been getting REALLY REALLY positive reviews from people and it's the go-to place for learning about how light works and how to get started with flash.

Anyway, when you're doing light painting, you don't need any light modifiers.  Why? Because the exposure is so long that you can physically move the flashlight around and thus make the light come from a larger area.  Suppose you have a softbox which is 4′ x 4′ in size.  You take a picture using a thirty second exposure and pop the flash from the softbox.  The light will be soft because it comes from the large softbox.  Now suppose you take another picture using a flashlight.  You trace the shape of the 4′ x 4′ box by moving the flashlight during the 30 second exposure.  The result is that the light painted shot is just as soft as the softbox shot.

You'll see during the video above that I keep waving the flashlight around.  The more I swing my arm to light paint, the softer the light on that area becomes.  When I want the light to be harder, I don't move my arm as much.  For photographing the silo “barn” area on the photo, I walk around a bit so I can wrap the light along the curvature of the silo.


Hopefully this light painting tutorial has pointed you in the right direction for getting great shots next time you're out in the night and wanting to do something different or unique with your shot.

Light painting is really fun, but it can yield disastrous results in the photo if you don't understand the basic principles, so hopefully this will have helped.  Good luck!

  1. Beautiful shots, and these tips really clarify the process! As someone who’s always wanted to play around with light painting but has never had the chance, I’m going to take this as my sign to get out and try it.

    I’d never thought of using a headlamp for something like this, but your rationale makes perfect sense. Is making the necessary moments still possible when you have the light on your head? It seems like the headlamp might not have quite as much maneuverability or flexibility as just using a flashlight in your hand…but I’m also not an expert! I’m guessing it might just be an acquired skill.

    You mention that angles are key . Do you normally take the low angle with every painting you make, or does the decision on the angle come more from the individual characteristics of each part of the shot? Seems like it’s probably best to find which particular angle emphasizes each feature of the scene, but I’m curious about your more experienced opinion.

  2. First of all – thank you fore the great tutorial!
    I have one question. You wrot:
    “Really, any flashlight can work for light painting, but I do think that if you just invest $15 or so, you can have a much easier time. I CANNOT recommend this headlamp on Amazon strongly enough.” – it means that you do not recommend this headlamp.
    But in the next sentence, you say that: “I USE that headlamp for all my light paintings for a few reasons:…”
    So question is – which exectly kind of flashlight you recomend to use for light painting?

    1. Brother, he is saying that he cannot recommend the flashlight enough, meaning that no matter how much he recommends it, it will not be enough. (in comparison to how good it is.) To clarify better, it means that he DOES recommend the product.

  3. Dear Olim,

    It’s the same with “I can’t agree with you enough” which means that verbal expressions of agreement are insufficient to convey one’s sentiment of agreement. He meant to say that he is superlatively recommending the flashlight from Amazon. 🙂
