Concepts for Lighting
and Digital Photography |
|
Welcome to Chuck Gardner's photography and lighting tutorials which offer baseline concepts a beginner can use to evaluate and light any subject in any style. My approach is unconventional because it is goal and strategy oriented. I want the reader to understand the cause and effect for each action before any action is taken. It starts with a baseline understanding of how the eye is attracted when it looks at a photograph. The reason is simple. If one does not know what will attract the viewer's eye on a basic instinctive level, how can one create a photograph which effectively leads to viewer to what is most important in it? This is the conceptual foundation for everything I teach:
From that baseline it becomes quite easy to develop a combined lighting, clothing and background strategy to accomplish the underlying goal of a photograph for any subject and any style; leading the viewer to what is most important in it.
Tutorial Sections:Using a Histogram - Digtal Zone System - Introduction (top of page) - General Lighting Concepts - return to TOC - 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. (Added 1-12-2007) COI for THOU (The Hard of Understanding) This was done as a joke for a couple guys on the forum who said they didn't understand why a center of interest in a scene or portrait is important and that my entire "contrast attracts the eye" approach is a load of crap. But its a good place for you to start so you can decide after you read it if you agree. I don't want to waste your time. 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. From Clueless to Competent A tutorial to give a cluless beginnner to lighting a technically sound baseline for growth. Portraits by Window Light Diagrams showing set-up for short lit full-face, oblique, and profile views by window light. Used in conjuction with the Clueless to Competent tutorial for those who don't yet own studio lighting gear. Visually Effective Portraits Originally published in PBase magazine , this article will provide more conceptual background for the Clueless to Competent tutorial. The Role of 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. it is one of the most misunderstood aspects of studio lighting. 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. 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 veiwer to it. Painting a Background... or as I fondly remember it "Channeling Jackson Pollack and becoming one with the paint." (Added 1-12-2007) Metering a White Background 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.

REVISED 07-18-2006 How to use a Flash Meter - return to TOC - Metering 101 Metering exposure is really no more complicated than driving using the speedometer and keeping a eye on the side of the road for the cop with the radar. 1-16-2007 Lighting Ratios and Incident Metering Demystified Explains the difference between incident and reflected ratios and how to set ratios with a Sekonic L-358 exposure meter. Is a Hand Held Spot Meter Really Necessary? It was for using the Zone System with B&W film, but not for digital. But if you own or want one I reveal the simplest way to use it with a digital camera (1-28-2007) How to use a Histogram - return to TOC - Using TTL metering An explaination of how to use TTL metering effectively.

(PDF format) Digtital and the Zone System An explaination of why its not possible to use the Adams' zone system with digital but how range a digital camera can capture can be previsualized (PDF format) Metering and Printmaking in the Adams Zone System An explaination of printmaking for anyone who has never developed and printed Black and White film. (PDF format) Tips on Technique - return to TOC - Understanding Digital Exposure Digital exposures must be based on highlight detail to take maximum advantage of the dynmanic range (DR) of the camera. This tutorial explains my simple "White Towel" method for perfect exposure and how to determine the DR of a camera with just a gray card. Understanding Digital Color Digital cameras see the world in only three colors: red, green and blue. To record the color accurately the balance of those three colors must be set to match the color of the light. How to use a Gray Card A gray card is the most valuable tool a digital photographer can own and the only way to independently evaluate color. Metering 101 Metering exposure is really no more complicated than driving using the speedometer and keeping a eye on the side of the road for the cop with the radar.

What's in Chuck Gardner's Home Studio I'm not a professional photographer but I was trained by one of the best 35 years ago and learned my lessons well. My gear is similar to what a serious hobbiest might want for a well equipped home studio. My choices and rationale for purchasing are revealed here. What is the best focal length for portraits? It is the second question neophytes ask, right after "What lights should I buy?" This explains why question they should be asking is,"How far away should the camera be?" (Added 1-12-2007) What is the best focal length for group portraits? Two factors affect the choice of lens for group shots: perspective and edge distortion.

But if you own or want one I reveal the simplest way to use it with a digital camera (1-28-2007) Oldies But Goodies - return to TOC - Across the Digital Divide An oldie which still has some useful parts. It was a hand-out for classes I taught in 2001 while I was working in the Philippines. Digital was new and expensive then and the target audience were people who had not yet made the jump to digital. It was expanded to cover reproduction topics because I presented it at a graphic arts show to graphic designers. I hadn't been using a digital camera very long myself at that point, so I didn't have a wide selection to photos to use for illustrations. Pontification - return to TOC - Essay on Criticism, Conventions and Creativity Why learning technique doesn't stand in the way of creativity and why conventions and "rules-of-thumb" are benchmarks and vocabulary necessary for constructive critque. Benchmarks What are your goals in photography and how do you measure progress? |
