There was no sun that day, and I really wanted a sun in my photo. I figured I could create a nice sunset with a flash and a reflector dish.

The general rule when shooting in a natural style is to first dial your camera’s white balance setting to the ambient lighting. Then, you gel the lights to match the ambient color temperature. Gelling for an Overcast DayThe technique is simple, although may require some experimenting, shoot in slow shutter to have the movement effect Also, try white balancing each test shot in your PP software to see the approximate temperature to which each gel is balancing. You really have to work this out for yourself. The quote in mvrk2010's post tells you about all there is to say in print:

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.As you can see, the less light there is, the more saturated the color. Hence, when setting up a gel, the first thing you want to do is go low with the power and then dial it up to reach the look you are trying to achieve.

Thankfully though, in todays setup I will be showing you how to mix coloured gels with incredible ease, in fact it’s so easy, we’ll only be using one light to do it! Let’s dive right into how to go about working with gels. Starting with the most basic rule of every gel: it reduces overall light output. Think of gels as obstacles that cut a portion of the light’s power. Some gels like Profoto and Expo Imaging might say how much light was cut by each gel. As such, a blue gel cuts four stops of light, while a yellow one only cuts half a stop of light. You may want to intuitively dial the power-up and use gels on the most powerful light you have. The job of this light can be a little confusing at first as it appears to be a key light, that is placed next to you and pointed straight at the subject. And although this light is adding some front illumination, it is also acting as a fill light for our large soft top light as well. As I mentioned, place the softbox next to you and keep it at a height so that it can shoot light under your white sheet and onto your subject. Many people think you need huge sheets of gels to use them with soft boxes, but thankfully that isn’t the case and you can just as easily use small sheets of gels to colour your softbox too. Lighting scenarios throughout the day will include a church ceremony in a reasonably lit church in which no flash is allowed. Formals will be shot outdoors in both sunlight and shade at around 3 pm. The reception will be held in the evening in a hotel banquet room that is lit by incandescent tungsten lights which will be progressively dimmed as the evening progresses. The banquet room has 12 ft ceilings and walls that are an off-white color.If you want to reduce the intensity of your light and you’re able to dim the light, you might make dimming the light your first choice of operation. However, dimming an incandescent light source also alters the color temperature. Being made of plastic, flash gels are pretty durable. They don't tear easily, and while they can get scratched or fold marks, these don't affect the lighting. Because gels always show up in the shadow and need very little power to do so, I created a blue room in the studio just by gelling my fill light. As you know, fill lights are designed to lift shadows and be “invisible” themselves. A great way to fill a photograph is to bounce your flash into the ceiling and light up the whole room.

And they make 1/8, 1/4, 1/2 and sometimes 3/4 strengths of CTO or CTB for partial correction, subtle warming or cooling of the color. For example, people often use 1/4 CTO on a lamp to warm up for a night interior scene that should look slightly golden and cosy. They may use 1/2 CTO for a late afternoon effect and Full CTO for a orange firelight effect or a sunset effect.

Retrieved 2018-08-08.Take an initial shot…it should result in an 18% gray towel if the camera’s meter is doing its job. Now increase the FEC by about 1.3 to 1.5 stops and take a baseline test shot. The towel should now be white, with some texture still showing up. Similar colors may vary between different companies' formulations – for example, many have a color named " bastard amber", but the transmitted color spectrum may be different. For this reason it is often misleading to refer to gel colors by name. Even a familiar color name, like Steel Blue, transmits widely differing colored light in each manufacturer's line. As this was an initial test, I just played around with a few off-cuts of gels I had lying around in the bottoms of drawers in the studio. In the image I’ve shared here, you can see a 4” (10cm) square of two gels taped together. In some cases matching your artificial lighting to the ambient lighting can make an image weaker rather than stronger. If you're photographing a portrait under cloud or in the shade, technically you would add a light blue to your flash to match the color temperature of the ambient lighting. Same idea with the reception. The lights will start out colder and get warmer as the dim. Also, the flash color will become more and more prominent as the ambient levels fade. So now I would probably start with a 1/2 CTO and move up to a full or even 1 1/4 as the night wear on. Not seeing the lights, I can only guess at the color and brightness. In this case again, I would think the CTS would de-emphasize the redder tones but still add the orange/yellows.
