| Welcome to Chuck Gardner's photography and lighting tutorials which offer baseline concepts for beginners.Most wanting to learn portrait lighting and look for "playbook" diagrams to tell them where to place the lights on the floor when what they really need to understand is where the light needs to be relative to the face to flatter it. The problem with playbook solutions is that every face is a different shape, and not all the conventional playbook patterns are effective or flattering. |
My approach is perceptual and goal oriented. The "big picture" goal of the exercise of making a photograph and sharing it is creating the desired emotional reaction in the mind of the viewer. To do that predictably and effectively in a photo we need to consciously understand how the viewer will react on a perceptual level to implied body language and other sub-conscious clues in it:
Sun Tzu and the Art of Lighting This was a new take on answering the question, "I just bought some lights, now what?" in one of the lighting forums. It received many favorable comments from readers so I've added it here at the beginning as an introductory overview. Strategic Thinking Everything is learned by trial and error but there is less error and wasted effort if every new lighting problem you encounter starts with defining the fundamental goals of the exercise, which for a photo is what is most important and how you want to viewer to react to it. Becoming self-critical is the key to progressing up the learning curve so for each goal you set you should define criteria for success. Having a clear idea of what body language makes a person look extroverted and glad to meet a stranger vs. someone who is introverted and shy will make it easy to understand whether or not putting light in the eyes, or not, is the best strategy. Learn to think strategically from goals and you can figure out any new lighting problem. The Holistic Approach What's different about my approach is that it starts with the question of what makes a view react to a photo, then tries to answer it based on a understanding of human perception and the optical illusion which causes the brain to accept a pattern of contrasting tone and color on a 2D screen or print as being real. It's really all a magic trick, and like magic the secret in doing it well is understanding what the audience expects to see. When you manage to deliver it content in the photo looks "normal" and real and it triggers the same emotional reaction as seeing the same thing in person. This is an overview of the approach. The nuts and bolts techniques are contained the other tutoials listed below. Why do you use "hard" or "soft" light Much of what you'll read on this site challenges conventional wisdom and conventional terminology like light being hard or soft. Human perception is based on expectations. You know what a human head and face look like so the lighting style really doesn't tell you what the object looks like but rather the environment the object is in. The emotional reaction to the content is often the result of whether or not the context of the environment seems "normal" or not. Creating the illusion of 3D in a 2D photo All the clues about 3D shape in a 2D photo come from contrast patterns which trigger recollections of seeing similar objects and scenes in person. This tutorial explains our baseline for "normal" and how to mimic what is experienced in person in 3D in the 2D universe of a photograph. Light Space - A Communication Tool For Portrait Lighting The traditional practice of using the lens axis as the baseline for key light placement does describe the actual cause and effect of how lighting patterns are created on a face. I use the spot between the eyes as the "Compass Rose" for describing key light placement and a three coordinate system similar to Lab color space to describe where to put the key light in space relative to the face. To communicates to a beginner wanting to know where to put the key light can follow instead of the traditional labels like "short", "broad", "butterfly", "Rembrandt", etc. COI for THOU (The Hard of Understanding) This was done as a joke in response to a couple guys on a forum who said they didn't understand why a center of interest in a scene or portrait is important. It illustrates the holistic approach to lighting. Human Perception Exercise The BIG SECRET about lighting is revealed: It's not the light, but rather contrast and relative brightness of areas in the photo which triggers the brain to react and move the eye in a photo. This concept is the foundation for my contrast-based approach for teaching lighting. Seeing Photographically Basic photographic concepts for beginners. A quick "food for thought" outline of how a camera captures an image differently that we normally perceive with our eyes. Process Control of Exposure Basic photographic concepts for beginners. An overview of the three variables controlling exposure on a digital camera and a decision tree for deciding how to use them. Process Control of Color Basic photographic concepts for beginners. An overview of the how color is managed with a digital camera and problem situations to be aware of. Using the Camera Overexposure Warning Getting perfectly exposed highlights in clothing and skin is as simple as throwing in the towel. The best measure of exposure is the last shot taken and using a white towel as a test target will allow your camera playback to tell you when and exactly where over-exposure and loss of detail is occurring. The White Towel Method for Perfect Exposure without a Flash Meter An explanation of how to set exposure and ratios using a white towel and the camera over-exposure warning The dilemma, challenge and paradox of exposure A tutorial to explain technically correct exposure (i.e., matching the range of the scene to the sensor) and perceptually correct exposure (i.e., when a photo looks "normal".) and how they relate to each other. Four Light Studio Lighting Exercise A tutorial to explain the role of the four lights used in a conventional portrait scenario and how they work to fit the range of the scene to the sensor. Using Flash Outdoors Explains the overlapping roles of ambient and flash outdoors. From Clueless to Competent A tutorial to give a clueless beginner to lighting a technically sound baseline for photographing people. Portraits by Window Light Diagrams showing set-up for short lit full-face, oblique, and profile views by window light. Used in conjunction with the Clueless to Competent tutorial for those who don't yet own studio lighting gear. The Role of Fill The character of lighting is controlled with the tone of the shadows and they are controlled with fill. The type of fill and where it is placed relative to the face of a subject has a significant impact on the appearance of the highlights and shadows but is one of the most misunderstood aspects of studio lighting. Butterfly Lighting Variables Explains all the variables which will affect the appearance of the butterfly lighting pattern - when key light is aligned with the center line of the nose. Analyzing Faces A portrait photographer needs to understand faces the way a sculptor does; in three dimensions. The first vital step, before the lighting lights are turned on is to find the most flattering camera angle and distance. Poses, Noses and Ears The eyes and mouth convey the mood of the subject. The nose and ears distract attention from them. Here I discuss strategies for minimizing the distraction. Mirror vs. Camera This self-portrait exercise shows how mirroring the two sides of a face can help reveal asymmetry and which is a person's "best" side. Backgrounds and Clothing for Portraits Examines factors which influence the choice of background for a portrait. Key light and fill reveals the face but it is the contrast of the face with the clothing and background which draws the eye of the viewer to it. Lighting a White Background Perceptually Making a background white without "nuking" it and other common sense technical considerations. Photographing Groups The goals for photographing groups are different from those of a solo portrait and so are the technical challenges. This PDF format tutorial provides some effective strategies.
