Direct and Indirect Light
There are two types of light in this world; direct light and indirect light. Each of them serves a unique purpose in photography, and each has its advantages and disadvantages.
Direct and Indirect Light
Photography literally means painting with light. As light (photons) enters our digital sensor, the photons knock lose some electrons (photodiode). The camera can measure these electrons to construct the image.
Think of direct light as the opposite of side light. Instead of shooting at sunset, you're shooting at noon. The light, while still soft, is coming directly at your fabric. This reduces texture and hides flaws.
Direct Lighting ...
Light shining directly on the subject and producing strong highlights and deep shadows.
Direct Memory Access
The ability to use memory without a software interface.
Direct light comes from a point source, such as the sun on a clear day. Direct light produces dark, hard-edged shadows that crisply outline details. Here the light and shadows almost form an abstraction.
Direct light and reflected light (paint) have different primary colors. Yes? No? You lost me.
I am enjoying these lessons! ...
Strong, direct light creates short shadows. These are best used for emphasizing large shapes. This is usually midday sun, so don't completely dismiss it but work with it for strong shapes and forms that will still appear majestic in spite of shadows.
Mid-Day, Direct Light: This light is horrible for flower photography. This light should be used only if a diffuser is being used to soften the light.
Lastly, indirect light can be used to make your subject glow soft and pretty.

Reflectors (to redirect light)
Flat devices, mostly white, silver, or gold, that redirect the sun's and other source's rays. Lighting with reflectors is like lighting with lights - except no cables. Just cloud and wind worries.
-When you want to provide fill-in light for shadow areas, it is often desirable to substitute a plane reflector (sometimes called a reflector board) to redirect the light from a direct light source (fig. 1-15).
Is the face in shadow or is does direct light fall upon it? Are there distractions in the background that direct the viewer’s eye away from the animal?
They rate the screen under different conditions including direct light, bright light as well as normal indoor conditions. We assess how reflective the screen is, the purity of the colour and whether there is any noise (static) distorting the image.
You don't want direct light streaming in through a window because it will have too much contrast in the final picture. You might find that light near a big window, a doorway that opens to the outside, or under a porch.
Keep all the components from direct light. Stray light can penetrate the assembly and fog the film. Clean all the components before beginning, especially the felt strips on the holder. They prevent dust from accumulating on the print.
Using the direct light of a low-lying sun as it broke over a distant horizon, Papadopoulos needed no diffuser because the sunlight was adequately softened (and warmed) by layers of haze in the distance.
The SLT design has an electronic viewfinder, rather than an optical one, and as a result it doesn't need a movable mirror to direct light up to the viewfinder.
Waterfalls enjoy overcast days and indirect light. If you have direct sunlight you will get blowing of highlights very, very quickly. You can boost contrast and saturation later in PP. This is an example of a shot done on a completely overcast day.
Matthieu's work with sharp, direct lighting provided the high contrast necessary to emphasize the dramatic nature of the situation. Including the eye chart provided necessary context, but shooting at f/1.
Even though an in-camera flash has enough intensity for direct light on nearby people, this type of light can be quite harsh.
In general, the more direct light the better when working with fall foliage photography. I say this because the brighter the leaves, the more impact your photo will have most of the time.
Quality of Light. Direct light produces sharp dark shadows and contrast between light and dark. Diffused light, such as the light of a cloudy day, softens shadows and produces softer tones of gray in your photo.
What you need to do, is to avoid this direct light that creates shadows, and avoid those surroundings that create reflections in your jewelry.
The system uses a beam splitter (implemented as a small semi-transparent area of the main reflex mirror, coupled with a small secondary mirror) to direct light to an AF sensor at the bottom of the camera.
Because your flash fires directly through a lightbank, it produces direct lighting, even though the lightbank may have a diffusion panel in front of the flash tube to soften the flash.
Direct light is rarely interesting. Oblique light enhances contrast. Dawn and dusk light are beautiful times of day. Many buildings lend themselves to twilight or night views if there is adequate interior and exterior lighting.
As I'm sure you can see there is a lot of bright light behind the subject caused by the direct light from the setting sun. Not only is the backlight coming from the sun but also reflected from the water. About the mood.
Nothing you've ever seen before prepares you for the breathtaking quality of a total eclipse - an eclipse in which the disk of the moon blocks out all of the direct light from the disk of the sun.
The bare-bulb flash heads were directed away from the model to avoid any direct light on her. Use the white walls of your studio to bounce the light back.
14 Soft light is more forgiving than direct light. Diffuse flash and use reflectors to bounce light onto your subject to achieve this.
Consider other indirect light sources to enhance the depth of the background and props, too.
They're too close to the lens and they (with occasional exception) give harsh, direct light. That said, I know a very good wedding photographer who reckons that the built-in flash of DSLRs these days are pretty good, for when all else fails.
Lens Hood is a camera accessory that fits on to the end of the lens that can shield the lens from direct light rays that will cause lens flare or other aberrations in a photograph.
