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.

Direct Light
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 light
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!
You are completely wrong about your primary and secondary colors! GREEN is NOT a PRIMARY color! Green is a mixture of yellow and blue.

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.

Top 10 Beginning Photography Tips ...

Use Indirect Light
Try to avoid bright sunny days, which tend to increase the contrast and brightness of the colors. Instead, go for partial or full shade. Shooting on overcast or rainy days can emphasize the earth tones and the depth of color of fall trees and leaves.

Working with hard, direct light is as easy as placing your subject in a window (or outdoors) on a clear, sunny day and snapping away. But if hard light and high contrast are not the look you're going for, then it's time to modify the sunlight somehow.

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? A busy background along with poor lighting dictate the image is destined for the delete button.

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. But my favorite place is in the garage! ...

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. Instead it used a fixed, semi-transparent mirror to provide light to a focusing sensor, allowing the rest through to the imaging sensor.

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/1.4 provided the short depth of field necessary to blur it out.

Even though an in-camera flash has enough intensity for direct light on nearby people, this type of light can be quite harsh. Often only an external flash unit has enough power to bounce off a distant wall or ceiling and still adequately illuminate the subject.

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.

The lenses in the array direct light from the back of the main lens to the sensor. The sensor captures the light field between the Lytro's lens aperture and the sensor. The resolution of the photographs depends both upon the power of the sensor and the number of microlenses in the array.

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. Please read the following steps on how to avoid shadows and reflections in your jewelry or view example photo.

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.

4. Choose your time of day carefully. 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. Until virtually the moment of totality, the sun shines brightly in the daytime sky.

14 Soft light is more forgiving than direct light. Diffuse flash and use reflectors to bounce light onto your subject to achieve this.

1) The built-in flashes on cameras generally suck. 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.

The next thing I tried was to see the difference the umbrella made and how the diffused light differed from the direct light of the flashgun.
To be honest, that was as far as I got. So not very inspiring yet.

Electronic flash guns which sense the light reflected from the subject, and cut off their output when they have received sufficient light for correct exposure. Most units must be used on or close to the camera for direct lighting only.

DIFFUSED LIGHT or DIFFUSE LIGHTING - Light that is scattered and spread out as opposed to specular light. Diffused light is softer than direct light, with shadows that are less sharply-defined (lower contrast).

The only problems you have when using your flash is that the direct lighting tends to flatten the image and hide detail. It also may cast some heavy shadows behind the subjects.

EVIL (Electronic Viewfinder Interchangeable Lens): EVIL is a term widely used to describe a type of digital, interchangeable-lens camera that, unlike a conventional single lens reflex camera, does not use a mirror system and pentaprism to direct light from the lens to an optical viewfinder.

If the window light or even a bright artificial light is causing your picture to be
underexposed or overexposed, take the picture from a different angle or move to
an area where the direct light is not included in the scene.

" Photographers devote so much time and discussion to the subject of light that it's easy to misunderstand its emphasis. New photographers often interpret the focus on light in photography as a need for even, direct light-and lots of it-in every scene they photograph.

Its power is enough to light subjects up to 3 or 4 meters away and it can be perfect for filling in dark shadows when capturing images in harsh sunlight.
It is less suited for direct flash however, because it emits a hard direct light that
could be softened a little by taping a ...

But it was not until I turned the corner that the light caught my eye once again. It was only for a moment or two that the direct light on the handsomely dressed guard created this opportunity. Again, the light lead me to the image.

The idea behind a light tent is to create an indirect light source thereby reducing shadows. I found this box cumbersome to work with, as I could not get the angles I wanted on certain sized objects. Secondly, it did not fold up, so storage was troublesome.

Microlenses capture the light striking the top portion of the camera sensor's pixels and redirect it into the pixel for processing. Microlenses are often angled along the edges of camera sensors in order to capture and redirect light back into the pixel as a method of reducing light falloff on the ...

Shooting in available daylight looks horrible and amateur: shadows in people's eye sockets look completely black on film and make people's heads look like skulls while sun shining off foreheads make everyone look bald. Fill the shadows with fill flash or a white reflector and dim the direct light ...

Unusually for its tiny size, Canon managed to squeeze an optical viewfinder into the earlier IXUS 100 IS / SD780 IS, which while delivering a tiny image, was at least a useful alternative for composing in bright direct light or to squeeze a few extra shots out of a failing battery.
