Introduction To LED Lighting

Introduction To LED LightingYou know how you never have enough lights to do the shot you want? Today I am going to solve this problem once and for all. I'm going to show you how to get all the light sources in the world for just a few bucks. How? With LEDs.

Lighting with LEDs is a ton of fun. It is also a great way to practice lighting. Why? Because LEDs are cheap. Having a ton of LEDs allows you to position a huge amount of light sources on any miniature detail oriented given setup - Provided that the setup is small enough.

Photography with LEDs - The Basics

Introduction To LED LightingThere are a few things that you need to consider when going in the path of LED lighting. 

LEDs are only giving that much light. And by "that" I mean not a lot. If you want to be at that place of short exposures and decent depth of field, you'd better get a huge bunch of LEDs. Fortunately though:

LEDs are really cheap. I get my fix at DealExtreme where you can literally get tens of them for about a dollar. (This is like 10 times cheaper than Amazon).

Another thing about LEDs is that (at least the ones I got) have a creepy cold white balance and poor CRI. The white balance can be taken care of once you shoot RAW (which I heatedly recommend when using LEDs). The CRI (Color Rendering Index) is a tougher issue. It will give you a certain look - it is OK for some images, however it takes from the how real the light looks.

Last thing on LED basics is that LEDs are small. That means that they provide hard light.  In fact they are so small that they provide very hard light.

Now, for the sake of fun, I lit all the pictures in this article with LEDs, even the illustrative ones that I would normally light with a strobe. You know eating my own dogpile.

LEDs Are Easy To Position

Introduction To LED LightingThis is one of the first things you'll notice about LEDs. Since they are so small and weight close to nothing, setting them up is a very small effort. Using a bit of Gaffer's tape you can stick 'em almost anywhere. Like on a chair, like I did in the shot on the left, which is part of the ring light illustration that I did.

Another option is to simply place the LEDs on the ground, like I did on the image above. When doing this, you need to remember that light is very focused and will not go upwards. This means that only the bottom of your object will be lit. This is OK for some types of shots. 

Introduction To LED Lighting If you need some light going up, though, you can even place LEDs on top of each other to create a small ad hoc tripod. This is another trick I used on the ring light illustration shot.

Last option is to use some plasticine to attach the LEDs to any smooth surfaces, or to give them a slight rise or decline.

The 1$ Ring Light

Introduction To LED Lighting Since LEDs are so cheap, you can make banks of LEDs to create interesting lighting that will usually cost you big dollars.

If you closely look on the image on the left, you will recognize the shadow signature of a ring light - there is a cool shadow thing going to all directions of the shoes. YAP it's a LEDs operated ring light. (And yes those are the same shoes).

Here is how to make a LED ring light in two easy steps:

Introduction To LED Lighting Step 1 - Create a Velcro hook strap that wraps around your lens + 2 centimeters. I used self adhesive Velcro for this. At those 2 extra centimeters, attach some loop Velcro. This will enable you to make a Velcro strap. Simply attach the loop side to the hook side with the adhesive side facing outwards. Click the image on the left for more details.

Introduction To LED LightingStep 2 - Attach LEDs to the adhesive side of the Velcro. Go one LED at a time until the entire strap is covered with LEDs. Now you have a LED strip. 

Before you run and bind it around your lens, note that this will make an excellent strip light. OK, now bind it around your lens. See the image on the left. This is how it looks like on my sweet Nikon 85/1.8.

And here is a link to the setup for the ring light photograph. Note the LEDs on the chair and on the floor.

Total Control

Introduction To LED Lighting Since LEDs are so small and so focused you can have full control on where you want light and where you want dark. In the image to the left (click for more info) I used a restricted LED light to throw light on the edges and white portions of the shoe.

I did this with a technique called light painting, however, the same principle will apply to static light as well.

Introduction To LED LightingThe light bean from the LED was not focused enough so I used a black straw (gridspot leftovers) to further restrict the light.

In fact, the light beam was so narrow that it was almost pen like. I had total control on where I wanted the light to hit. 

Similarly, you can position restricted kickers or rim lights made from LEDs. 

LED Light Painting

Introduction To LED LightingLast LED thingy for today is a personal favorite - Light Painting

In light painting, you use long exposure in a dark location and a moving light source to burn specific and very accurate parts of the image with light. 

Here is how it works. Since the setup is dark, the long exposure by itself contributes very little to light hitting the sensor.

When you introduce a bright light source, it has a huge impact on the sensor - a spot of light will be created where the light source was. If the light source is moving, a stripe will be recorded.

In the image on the left, I used two different light painting techniques (note that I left the creepy WB on this one):

The shoes - I used a similar LED and straw device to the one describe in the Total Control section to create interesting light on and under the shoes.

The dynamics - I than used a bare LED to create dynamic looking strips on the top half of the image

Summary

To sum up LEDs for now, here are the main points we discussed:

- LEDs are cheap, really cheap, however they provide little light which makes them ideal for small setups.

- LEDs have weird behaving light - bluish WB and poor CRI. Make sure you know what to expect by experimenting.

- LEDs are small and focused - they will produce very hard light, and you can exercise great control over that light.

- LEDs are FUN, FUN, FUN

I work for one of the biggest lighting companies in the world. Just wanted to throw in: There are also really powerful LEDs. Strong enough to act as the headlight of a car. Of course those are not cheap anymore. Also there are LEDs, again not among the cheapest ones that have a warm color. Just watch for the phosphor treated ones.

Love it!

Very cool concept, especially the ring light. :)

Drew, a LED flash light is a must on any photographers kit.
It can also help when it is to dark to focus. simply point it at the desired area.

In many cases it is stronger than the build-in focus assist

Simple, but amazing!

What an idea........ Why this has not been my idea?????? I am thinking on t-shirts with LED´s under the shirt...... I think this post has been the starting point of a lot of ideas.....

Best regards from Germany
Norbert

Great Idea!

Great idea! I like the "Total Control" result that you have archived by painting with light around the shoes.

Often the simple solutions are the most effective.

Fantastic write up

I have always loved LEDs and have used them in lots of electronics projects. Never thought of using them in my photograph. Will certainly try some of the methods described here.

Thanks,
Nick

Really nice discovery! It´s

Really nice discovery! It´s pretty beautiful what we can do with LEDs. I didn´t know at all....
Thanks for the post

Frankly speaking, your's in

Frankly speaking, your's in an excellent post.You have define a total new concept and take the creativity to a total different level.i am suprised and amazed by the outcome.I particularly liked the idea of pasting LEds all round your camera.An the use of LED on the edge is simply amazing!!!

LED's are fun

Colored LED's can take you a step further. And beyond that, they can be programed to do many neat things in the right hands. I received a fake rose at a concert that has three LED's of different color and it can cycle thru many different hues allowing for a lot of creative possibilities.

I think the LED ropes have a lot of promise too.

Great post!!

Hi Eric.

Ha! looks like you were hunted down and trapped by the light painting damon :) The ropes can do wonderes there.

You get what you pay for

  • Þór

If you stick to the cheapest LEDs you can buy, you get exactly what you pay for, and not a teensy bit more.

Check out http://www.globalsources.com/manufacturers/High-Power-White-LED.html or Google "High Power White LED" - real high-power LEDs do cost a few dollars, but then you can get (at least) up to what this offers:

http://linova.manufacturer.globalsources.com/si/6008827225270/pdtl/High-...

80W LED array which gives three levels of white with up to 6800 lumen and a colour temp of 2700K to 7000K.

re: money

  • udijw

I assume you're referring to the issue of low light coming from the LED.

While I see the point of buying high power LEDs I was satisfied with the low end LEDs that I had. I jst had to use a tripod. for about 50c each there is really no competition

custom white balance

  • August 13, 2009
  • jp

A custom white balance, (using something like the expodisk and other tools) with RAW or jpeg should solve the WB issue. Love the LED lighting - I'm going to work on this one...

Clever...

The swirl effect with light painting is great.

How long are the exposures, like 5-10s?

re: exposure

  • August 14, 2009
  • udijw

If I remember correctly, exposure was about 30 seconds with f/11

Wow.

Wow, this is an great idea. I think I need to buy a bunch of LEDs and give it a shot. Thank you for your awesome idea and article. :)

Nice work

Hey, this is a great piece. It's always great to hear of innovative ways to light and this is pretty cool. I particularly like the light painting piece. Keep up the good work.

LED Lighting

I took this photo a long time ago with one of these keychain lights. This is a cool idea and fun.

Wow!

You had me at cheap. ;) I have not invested a lot into lighting because, it costs money and the sun is cheap. but the ring light idea looks awesome, and I'm going to have to try it. :) Thanks for sharing this great tutorial.

They're $7 + here in Hawaii. Where do YOU get them cheap?

re: LEDs

  • August 14, 2009
  • udijw

@ JP - at the core, you are right. custom (or post) White balance should fix any color shift. just as long as the LED (or any light source for that matter) has high enough CRI.

@ Lewis, Jason - Thanks, On top of allowing nice images light painting is also a great ton of fun (try writing your name - it is a riot).

@ Jim - don't know if this is intentional, but this is a Light Painting on your image is a wonderful photographic pan.

@KateInHawaii - have you tried dealextreme.com? they sell pretty cheap there online.

LED Headlamp macro forest photography

I've been using a PETZL Tikka XP headlamp I bought for caving for taking macros of fungi,insects,orchids etc in dark forests for a few years now.
It works better sometimes in manual mode & sometimes better in P (auto), no idea why. I've had some great successes though.
Long live LED !

Another Great Tutorial!

Thanks for the tip. As a Fort Lauderdale wedding photographer I am always looking for ways to take macro rings shots. We will definitely try this! Thanks!

Very Interesting but no info on wiring circuit,power source and type or voltage needed ETC..

Awesome.

Very very awesome idea. I read this, and ordered a bunch of LED things in order to do this for myself, and forgot to thank you. So thank you. :)

To Anonymous above: don't bother with wiring and power sources if you're into making a macro light. Find yourself a bunch of cheap LED keychains/torches/etc with varying numbers of LEDs. More expensive (yet only £20 for my latest acquisitions, batteries included), but that way you don't need to worry about power sources, wiring and all that stuff. :)

My sideline is security and I use a little led booklight and it puts out more light than my mini-maglite does so I just clip it on my hat, and for about US$3.00 it is hard to beat the pricing.

You can find these at local bookstores, and I have used them in a few shoots too, especially night shoots with an overcast sky. you throw a colored film on these and get all sorts of nice effects

LED Light Panels

  • June 13, 2011
  • James F

Although not as "cheap" as the LEDs mentioned in this thread while searching for LEDs to use I have stumbled upon another LED light source to use in my shoots.  There seems to be a couple of different companies offering this solution however I have found this one to be the most economical...

http://www.ledlightpanel.ca/

They're light weight compact and offer a very broad and soft light on my subjects. 

I purchased two 6" x 6" panels and am quite pleased with the effect but if someone happens to test one of their larger LED panels id be quite interested in hearing about the results.

Just thought id share.
