About this deal

You may be wondering why you would want to use an ND gel with your flash. Why not just turn the power on the flash down instead if it's too bright? Well, there can be instances where the flash is too bright even at minimum power. This is where an ND gel can come in handy. One of the main uses of flash gels is when you are photographing under colored lighting (e.g. tungsten, fluorescent), but need to add in a bit of extra lighting with a flash. Flashes are color balanced to daylight, whereas fluorescent lighting has a green tint, and tungsten appears quite orange. This image was a bit complicated to set up, but here the gel is very important cause without it the image would lose a lot of sense and credibility. Photograph #7 – selective lighting Accurate white balance depends on the color temperature of the scene. To have technically correct white balance, the color white is represented as perfectly white in your image. This is part of why many photographers take a photo of a grey or white card as a reference to later use to adjust the raw image for white balance later. Many also may just shoot on AWB.

I personally don’t see the Optical Snoot a specialist lighting modifier any more and I really do believe this is a must-have modifier for any strobist at this point. Sure, get your softbox and your beauty dish first, but then get yourself an optical snoot. I guarantee you won’t regret it and once you have one, you’ll end up using it way more than you thought you would. Temperature adjustment gels will make a light source “cooler” or “warmer” depending on what is used. For instance, a CTO (color temperature orange) will make a light warmer, whereas a CTB (color temperature blue) will make it colder. The CTO and CTB gels can be easily confused with orange and blue gels so it is important to understand that those gels are not the same, and will not give a similar effect at all. I remember once trying to recreate sunlight using a yellow gel, only to find out that this didn’t work at all.

Let’s begin by identifying the color of your flash. Your flash is the same color as full daylight, so if you took a photograph at mid day, in full sun and set your white balance to daylight and added a flash into the image, you would end up with completely matching color. This is your starting point. Full sun is a slightly blue light source and so is your flash. They both sit on the scale at 5500 K. In reality, there are any number of colour combos we can create here and you can place any two gels together that you like. In fact, you don’t even need to stop at just two gels and I even created 3 strips of colour for a couple of setups, but more on that later. The GAMColor line from Rosco employs a three digit numbering system, organized by the wavelength of the principle color in the family, i.e.: Blues in the 800's with primary blue at 850 (though the manufacturer's numbers do not relate directly to any wavelength, transmission, or frequency). The same applies to Greens in the 600's, Reds in the 200's, etc.

The church is the only place with a restriction on the use of flash…you’re free to use flash and/or strobe for both the outdoor formals and for any of the reception shots. This process is usually used in stage lighting, photography, television, cinematography, and other disciplines. Switching to a 1/4 and 1/2 CTS, should help de-emphasize the groom's sunburn and still give the bride a nice natural but slightly warm color. I'm going to warm up the WB as I add or increase the gels. I want the WB to be a touch cooler than the light from the flash and, if possible the ambient light in between the two.As I mentioned above, if we place gobos into the modifier itself, we can focus the shadowy shapes with razor sharp edges thanks to the lens on the end of the modifier. However, if we place something in front of the optical snoot and not inside it, the resulting shape will be very blurred and out of focus. It’s this feature that we’ll be using to our advantage in this setup. The reason shadows on the face may look green when shooting indoor portraits is the inherent green in fluorescent lighting. The green comes from an inconsistency in tint that comes from indoor fluorescent lights. If the light is green enough you may need to add green color gels to your strobe. This is less common now that LEDs are more widely used. Purchasing and Attaching Gels

Just like the CTO example above, the gels allows to create some strong moods by using selective lightingIf the flash is over-corrected, use a weaker gel. If it's not corrected enough, use a stronger gel. You can double up on gels to create a stronger effect too. Two half CTO gels will have the same effect as a single CTO gel. A color gel or color filter ( Commonwealth spelling: colour gel or colour filter), also known as lighting gel or simply gel, is a transparent colored material that is used in theater, event production, photography, videography and cinematography to color light and for color correction.
