The two most common issues are not being able to get the background color bright enough or the background color gets too washed out. Let’s get right into it and see how we can improve our technique and use colored gels for our backgrounds more effectively.

The Setup

The setup is very important to make sure everything goes smooth. First off, I prefer using a black seamless paper for the background. Black paper will result in more vibrant colors where a white background will make the colors look duller.

Secondly, you need to make sure that your lights that are lighting your subject are not hitting the background which will cause the colors to wash out as well. The two ways to do this is to use more side-lighting and to increase the distance between the subject and the background. The other advantage of increasing the distance between the subject and the background is that you will be less likely to get color spill on your subject from the background light.

Getting The Exposure

Probably the biggest mistake people make when learning to use gels is to get the lighting for the subject all setup and then try to dial in the background. If you do this in the opposite direction you will get where you want much faster. The following are the three images I took in order to get my light dialed in.

Initial Background Shot

In the initial background shot you can see that I had no light turned on the subject. The background wasn’t quite bright enough so I needed to power up the background flash another stop.

Subject Lighting Test

in the first lighting test with the subject light, the background is nice and bright from turning the power up, but the subject is still underexposed by about a stop so the main flash needed to be powered up more.

Final Shot

In the final shot we have enough light on the subject which is coming from about a 45 degree angle to camera-right and using a Large Rouge Flashbender to flag the light from hitting the background giving me exactly what I needed to get the shot.

The final settings are as follows:

Main Flash: 1/8 Power
Background Flash: 1/8 Power
ISO: 200
Aperture: f/5.6
Shutter: 1/250th

Be sure and experiment with gels and see what you can come up with and be sure and share your images with us.

What you will need

To start off with, you should get a set of gels. The set I recommend is the Strobist Gell Collection since it contains a large number of gels of different colors that are pre-cut to fit most speedlites. Second, you will need some way to attach the gels to your speedlite. I generally use the Lumiquest Gel Holder or just some basic gaffers tape.

Once you have the gel attached to your flash, you are ready to get going.

The Lighting Setup

This is where people often get hung up because a poor setup can cause light to spill on to the subject or the main lights can wash out the color effect. Ideally you want 3 feet or more between the background and the subject to prevent spill and you want the main lights to be angled enough to not spill onto the background to wash it out. Later on we will look at some actual setups to show how they are done.

In the first image, we saw just a plain black background which was done with black seamless paper and the lighting was coming from an side angle to prevent hitting the background. In this image we have a single speedlite one 1/2 power with a purple gel shooting up from behind the subject. This is a very simple yet effective setup since it used a single light source. To help the light spread out, the flash zoom was set to 24mm to make it as wide as possible (without a modifier).

If the flash isn’t set high enough you won’t get much of an effect. If it is set too high, the color will wash out and you will get white.

If you want to take it a step further add a second light with the same or a different color. In this case I changed the purple to a red and added a second flash with a blue gel. Take notice that where the colors overlap they actually mix and become purple. If you are trying to use two different colors, you will need to keep this mixing effect in mind and might have to take steps to flag the two flashes to keep the colors from mixing.

Another thing to try is to use multiple gels on a single flash by covering half of the flash with one color and the other half with a different color. For a recent benefit shoot I tried this with pretty decent results.

Again you can see the distinct blue and red colors but a purple where the colors mixed. I am going to continue to play with this technique and see what I can get with possibly using a vertical card in between the two gels to try to keep the colors separated more.

Even though the colors mixed more than I would have liked, the overall effect was very nice although I later wished I had used a white or black background as the gray seamless was a little too drab where the color wasn’t hitting it.

The following is an image from the shoot showing how the images turned out.

What I really wanted to achieve was a red, white, and blue effect so back in the studio I start experimenting to see what I could come up with. What I finally came up with was a three light setup with bare flashes with the gels on the bottom and an non-gelled flash higher up to provide a white splash. If I used just a bare flash for the white, the spot was too big and washed out the other colors so I added a Rouge 3-In-1 Grid to keep the light contained.

The first test was alright but the white spot was too small.

To solve this, I took the small grid out of the Rouge Grid so I would get a little larger of a spot and got the resulting image.

There I had it, a red, white, and blue background effect. The next image is a shot of the actual lighting setup so you can see how it was all put together.

Hopefully this will inspire you to get creative with using gels for different background effects. It just takes a little patience and practice to get it all dialed in right, but once you do, the possibilities are endless.

My good friend Chris Diset comes over yesterday and tells me that his significant other Debra has come up with a solution.

Fortunately we all had some of the small Think Tank Photo Pixel Pocket Rockets (for 6 CF cards) laying around that Think Tank Photo had given away in a recent promotion.  The trick here was to cut the separator out of each pocket, this way the gels would be able to fit into the pocket perfectly. This is not the easiest thing in the world to do, you need to be careful as the material in the back of the pockets will tear easily.

Since I use a Large Pixel Pocket Rocket for my CF cards, and its a different color than the small one, this wouldn’t be confusing during the heat of a shoot.

The result is better than I expected as the gels fit absolutely perfect into the pockets. The next decision was how to organize them, and while you may do it differently I figured I would explain how I decided to do it.

The top pocket holds my main color correction gels, this includes the CTO’s (Color Temperature Orange) or the green’s for correcting in fluorescent lighting. This middle pocket holds the color effects gels which is all of the rest of the colored gels. The bottom pocket holds all of the Neutral Density gels. This layout makes it very simple to find the gel you are looking for, and if you happen to drop it in the wind, the gels are not going to go flying everywhere.  This is such a perfect solution for storing gels that I am actually going to encourage Think Tank Photo to offer a version of this pouch like this.

So thanks to Chris and Debra for this awesome quick tip. If you have your own quick tip that you would like to share, please post in the comments section.

Watsonville, CA (PRWEB) January 26, 2009 — ExpoImaging Inc. (www.ExpoImaging.net), developer and marketer of innovative camera accessories, including the Ray Flash Ring Light Adapter, ExpoDisc Digital White Balance Filter and the ExpoAperture2 Depth-of-Field Guide, today announced that it is now the exclusive U.S. distributor of Honl Photo Professional Products.

Summary
The FX is a colored gel system that comes with five colored gels (blue, green, red, yellow, and amber) and a gel holder that attaches to your flash with velcro. The kit contains the holder, the five gels, a carrying case, and velcro pads. The FX is available at most camera shops or online for around $35.00.

Usage
The FX attaches via velco to your flash with the included velcro pads. If you are like me and use a variety of modifiers, putting some velcro pads on the flash really isn’t an option. Instead of sticking the velcro pads on, I use a Honl Photo Speed Strap and the FX attaches to the Speed Strap quite nicely.

To use, pick out a color you want and insert it into the FX holder, attach the holder to your flash and you are ready to go. Keep in mind you are going to lose about 1 stop of light when using the gels so adjust your flash accordingly.

Shown here is the FX attached to a Canon 580 EX II and fired at a black muslin wall so you can get a feel for how to use the system. At first you may think you want to aim the colored light at a white wall for the best reflection, but in fact, the opposite is true. A white wall or white seamless paper will reflect the light and just give you white instead of the color you want. Using a dark grey or black background such as seamless paper, black muslin, or black velvet will give you the best effect.

By adjusting the output of the flash you can control the brightness of the background and adjusting the position can create a gradient effect as you can see that the color goes from brighter “sweet spot” to darker edges.

“The Lumiquest FX is going to be one of my favorite gadgets to have around for those times you need something a little different.”

I will usually have the flash hanging off a long boom and triggered with Gadget Infinity Flash Triggers. In the studio I will also shoot tethered using DSLR Remote Pro.

As you can see, a subtle color on background can make a huge difference on a portrait shoot. Let’s take a look at several product shot images taken with and without the FX system in place.

Results
The results are exactly what I was looking for. The color is vibrant with a predictable fall-off allowing for easy adjustments so that you can get the exact effect you are looking for and for less than $40, it will work with virtually any flash brand.
