Open Loop and Closed Loop Lighting patterns.

Open loop and closed loop lighting patterns are two lighting techniques used in photography, especially in portrait photography, to create different effects on the face of the subject.

Closed Loop

The open loop lighting pattern is created by positioning the key light source, which is usually a studio light, to one side of the subject's face and slightly above eye level. This lighting pattern creates a shadow on the opposite side of the subject's face, with a small triangle of light visible under the eye. This is also known as the "Rembrandt lighting" pattern.

Open Loop

On the other hand, the closed loop lighting pattern is created by positioning the key light source directly in front of the subject's face, often from above. This creates a soft, even illumination on the face, with no visible shadows.

Both lighting patterns can be implemented on faces, and the choice between the two will depend on the desired effect. The open loop lighting pattern creates a more dramatic effect, adding depth and dimension to the subject's face. This pattern is often used to highlight strong features, such as cheekbones, and is ideal for creating a moody, dramatic portrait. In contrast, the closed loop lighting pattern creates a more evenly lit face with a softer, more flattering effect. This lighting pattern is ideal for portrait photography that aims to create a gentle, serene or approachable appearance.

It is important to note that open loop lighting may not be suitable for every face shape or every situation. This lighting pattern can be particularly harsh and unflattering on subjects with prominent or irregular facial features, and it can create unappealing shadows in certain situations. Additionally, the open loop lighting pattern may not be appropriate for some types of photography, such as product photography, where a softer, more even lighting is needed.

In contrast, the closed loop lighting pattern may not be suitable for situations where you want to highlight specific features or create a sense of depth and dimension in the subject's face. This lighting pattern may also create a flat, uninteresting portrait if not used correctly.

In conclusion, the choice between the open loop and closed loop lighting patterns will depend on the desired effect and the subject's face shape and features. When using these lighting patterns, it's essential to understand how they work, experiment with them, and evaluate the results to determine which lighting pattern best suits your subject and situation.

Camera Height and what it does.

The camera height in portraiture can significantly influence the way a subject appears in a photograph. By adjusting the camera angle, a photographer can convey different emotions, moods, and messages. One of the key factors affected by camera height is the perception of dominance versus submission in a pose.

When the camera is positioned above the subject's eye level, it creates a dominant effect in the photograph. This is because the viewer is looking down on the subject, which can make them appear smaller, weaker, and more submissive. This type of camera angle is commonly used in portrait photography to create a sense of power, authority, and control.

For example, if a photographer wants to create a dominant pose in a portrait, they may instruct the subject to look up towards the camera while tilting their head back slightly. This can create the illusion of the subject looking up at the viewer, which can be interpreted as a sign of submission.

On the other hand, when the camera is positioned below the subject's eye level, it creates a submissive effect in the photograph. This is because the viewer is looking up at the subject, which can make them appear larger, stronger, and more dominant. This type of camera angle is commonly used in portrait photography to create a sense of vulnerability, openness, and intimacy.

For example, if a photographer wants to create a submissive pose in a portrait, they may instruct the subject to look down towards the camera while tilting their head forward slightly. This can create the illusion of the subject looking down at the viewer, which can be interpreted as a sign of dominance.

It's important to note that camera height is just one of many factors that can influence the perception of dominance versus submission in a pose. Other factors, such as body language, facial expressions, and lighting, can also play a significant role in how a subject appears in a photograph.

In conclusion, camera height in portraiture can significantly influence the perception of dominance versus submission in a pose. By adjusting the camera angle, a photographer can create different emotions, moods, and messages in a portrait. Whether a photographer wants to create a dominant or submissive pose, it's important to consider all of the factors that can contribute to the final image.

Color and Clothes

Photography color theory plays a crucial role in the selection of clothing for models in photo shoots. The colors chosen can impact the mood, atmosphere, and overall tone of the image. Understanding the basics of color theory can help photographers, stylists, and models make informed decisions about what to wear for a successful photo shoot.

The color wheel is a useful tool for understanding color relationships and how they can be used to create harmony or contrast in a photo. The primary colors red, blue, and yellow, are the building blocks of all other colors. Secondary colors are created when two primary colors are combined, such as green (blue and yellow) or purple (blue and red). Tertiary colors are created by mixing a primary and a secondary color, such as blue-green or yellow-green.

When selecting clothing for a model, it’s important to consider the color scheme of the background and surroundings. If the background is neutral, such as white or gray, the model’s clothing can be bold and vibrant to create contrast and draw attention to the subject. If the background is already colorful, the model’s clothing should be chosen with care to complement the background and avoid clash.

Complementary colors, which are opposite each other on the color wheel, can create high contrast and drama in a photo. For example, a red dress against a green background or a blue shirt against an orange background. However, this technique should be used judiciously, as too much contrast can be overwhelming.

Analogous colors, which are next to each other on the color wheel, can create a harmonious and calming effect. For example, a yellow dress with a green scarf or a blue shirt with a blue-green jacket. This color scheme works particularly well for portraits and fashion shoots where the focus is on the subject and not the background.

Monochromatic color schemes use variations of the same color for a cohesive and sophisticated look. For example, a model wearing an all-black outfit, or an all-white outfit, can create a sleek and stylish look.

In conclusion, photography color theory is an important consideration when selecting clothing for models in photo shoots. Understanding how colors interact with each other and how to use color relationships to create mood, atmosphere, and impact can help ensure a successful photo shoot. By considering the background, color wheel relationships, and the desired mood, models, photographers, and stylists can make informed choices about what to wear for a memorable and visually stunning image.

Light Facts!

Light exhibits both wave-like and particle-like behaviors, a phenomenon known as wave-particle duality. This idea was first proposed by Louis de Broglie in the 1920s and confirmed by experiments, such as the double-slit experiment. Light can act as a wave, exhibiting characteristics such as diffraction and interference, and as a particle, exhibiting quantized energy as photons. The dual nature of light is described by quantum mechanics and is a fundamental aspect of our understanding of the nature of light and matter.
