The Main Light
Click to explore the main light.
Outdoors the brightest source of light is usually the sun. In the studio, the sun's role is filled by the main light. Like the sun it's the brightest source of light and casts the darkest shadows.

Main Light (Key Light)
A main light is the light that illuminates most of the subject's face. It is also the largest light in any lighting arrangement and the brightest.
Fill Light ...

MAIN LIGHT - Same as "Key light"- the principal source of light, usually in a studio, and generally the brightest light on a subject or scene.
MAKE-UP ARTIST - A person who specializes in applying and touching up a subject's make-up for photography sessions.

Makeup, Grease Paint
A little makeup may do what a lot of lights can't; too much, especially on close-ups, is worse than none. Tip: Examine makeup under your lights.

~ see Key light.
Mask is an opaque material used to cover the edges of the printing paper, and thus produce borders when the paper is exposed to light.
Masking is a system of controlling negative density ranges or color saturation through the use of unsharp masks.

The ~ is at the bottom left, with the fill light at the right. The fill light should be one to two stops less bright, it's purpose is just to fill in the shadow created by the ~.

The ~ is close and feathered to give a little wrap around. The rim light is also feathered so only the edge of the narrow beam lights subject.

Unlike the ~ source, the simplest location for a fill light is near the camera's line of sight ("on-axis"), but not so close that it appears in your image.

81 The ~ is the primary light source illuminating the subject. It is usually set at a 45 to 60-degree angle from the lens axis. This lights the short side of the subject’s face, creating a triangular highlight on the broad side of the
subject’s face.

Pushing the ~ further round to the side gives this second setup. The light is now more or less at 90º from the camera, the fill light hasn't moved at all.

Now for the ~. I placed an SB-800 on camera left at roughly 6 feet high. Now since my white balance was on tungsten, I added the tungsten gel that came with the SB-800 (the orange one) on it to get natural skin tones. Done! ...

Outdoors as ~: Photography is all about the quality, amount, and direction of light. The more efficiently these factors interact, the better the photo. All three are part of the picture making equation.

Also called a ~, the key light is usually placed to one side of the subject's face, between 30 and 60 degrees off center and a bit higher than eye level. The purpose of the Key-Light is to give shape (modelling) to a subject, typically a face.

Using the flash as ~ means that the majority of the scene is lit by the flash's burst of light. Fill flash is used to fill in shadows or areas that would be rendered too dark without additional light.

In addition to the ~, I also used two Photoflex HalfDomes, which work great as rim lights. However, I did not add any modifying gels on these soft boxes, as I wanted them to project the same color temperature light as the existing daylight.

Broad portrait lighting is when the ~ is illuminating the broad side of the face and the shadow from the nose is being cast onto the short side of the face. In other words, broad lighting is when the more exposed side of the face is facing toward the ~.

Using direct sunlight as your ~ source is usually frowned upon because of its deep-shadowed contrast. If you get out early enough, though, dawn's first rays can work for you, as proven by Theophilos Papadopoulos's caper flower here.

You can even use the flash for your ~ source and downgrade the sun to being a fill-in or back-light.
Mixing light sources within your pictures, such as fluorescent lighting with a burst of off-camera flash will add colour to the background.

When shooting in nature, we rely on the sun as our ~ source. Most professional photographers know that the best light of the day comes at two times, the beginning and the end of the day.

Two weeks back during a photo shoot I had a problem with a wall power outlet that caused my ~ to go off. Suddenly my studio was in darkness and I trod on the (up until then fully functional) sync cable connected to my camera and the ~.

Reflectors are often used in photography to soften the effect of the ~ or to bounce illumination into subjects shadows. Light does not always fall exactly where you want it. For this reason reflectors are used.

I really like this setup because the ~ is quite strong and perfectly brings out any details-makeup is always crisp and vivid. Thanks to two fill lights, I'm avoiding any deep shadows, but at the same time, the effect isn't flat, as my fill light nicely sculpts features of the face.

Fill-in flash looks most natural when it's about a stop darker than the ~. When the flash-to-daylight ratio is too even, or when flash overpowers the existing light, the balance looks false and draws attention to the fact that you used flash.

A lighting effect produced when the ~ source is located behind the subject. Backlighting can be used to create a silhouette effect. Backlighting is also a technology for illuminating an LCD display from the rear, making it easier to view under high ambient lighting conditions.

At the other end of the scale, the Panasonic ZS10 tends to produce somewhat muddy results when flash is the ~ source, but copes very well when it comes to fill flash in brighter daylight conditions.

Most people tend to squint when they are facing the sun - the ~ source on a sunny day. If the sun is too direct the subject may begin to squint, which obviously ruins the portrait.

KEY LIGHT - Also called "~." The principal source of light on a subject or a scene, usually in reference to a studio light. The key light is generally the brightest light on the subject, or the one that will have the greatest overall effect on the image.

You can turn off the ~ and measure the fill lighting with a meter, you can move lights around to vary their strength, etc. But if you're taking a candid photo outdoors you have no such control.

To get a little more of a dramatic effect, I moved the ~ slightly more behind the ball and used a small silver reflector card to light the Super Bowl XLVII logo. This card was just out of the frame on the surface angled up to reflect light onto just the logo.

The ~ sources (the sun, flash, other lighting)
To understand light photography you need to understand what are the effects of the position of light source relative to the photographer and objects.

Keylight - the photographer's term for the ~ source that can cause predominant shadows.
Kilobyte (k) - these days, a very small unit of digital data storage. 1024 kilobytes make up 1 megabyte (MB) and 1024 MB equal 1 gigabyte (GB).

This will make the lights look their clearest, as tungsten is a manual setting used for shots where the ~ source is household light bulbs. If you're more experienced using white balance, play around with it a little (experimenting with it will improve your experience anyway).

-Broad lighting - portrait lighting in which the ~ source illuminates the side of the face closes to the camera.
-Brometching - obsolete, special method of producing a bromide print. The result acquired the texture of its support and appeared similar to an etching.

Hold your hand at an angle between pointing at normal camera position and ~ source.
Ansel Adams used only a reflected light meter, try using an incident light meter when photographing the moon! Mr Adams had the Weston Master reflected light meter designed and built by Dr.

A ~ source coming from below produces a look that human brains and eyes are instinctively programmed to perceive as unnatural. Horror films utilize low-placed lights all the time to create eerie effects that tell us something is very wrong.

High Key is a lighting descriptive term that is characterized by having the fill light be at or near the key (or ~) to produce a more uniformly illuminated image. High Key images have low contrast.

Also they tend not to emphasize the shadows of a subject which can lead to a feeling of depth. My answer to that is to use the ring-flash for my ~ and to use a small strobe like the YS-01 to add light from an extreme angle to lend depth to the pictures.

They all do the same thing; they give you a multiple light source that works in conjunction with high magnification. One strobe is close to the lens, one is off to the side. It's a portrait type of lighting, where you have a key light that's your ~ source, such as the sun, and then a fill, ...

The majority of DSLRs on the market come with integrated pop-up flashes. These are great in a pinch-providing fill light under a harsh high noon sun and creating the ~ needed to remedy dark indoor conditions. They have some drawbacks, however. Deployed in a fixed position.
