Welcome to Chuck Gardner’s photography and lighting tutorials. I’ve been on the Internet giving photographic advice and critiques on various forums since 1994 and something I’ve found beginning photographers struggle with is understanding exposure and making flash assisted photographs look natural to the point where the use of flash doesn’t trigger a “that doesn’t look right” reaction in the mind of the viewer. Two qualities make the brain accept photographic reproductions as reality: the same range of tone experienced in person as the scene is scanned and the eyes adapt and on camera flash techniques pdf same neutral color balance the brain adapts the in-person viewing experience to.
The problem achieving that result stems from the technical limitation of the recording medium: it usually can’t record the full scene range or adjust to color in the same way as the brain. Where my tutorials differ from most other “How to” instructions is that I explore and explain the perceptual cause and effect which are the underlying reason why it is desirable to use techniques I suggest such as Custom WB off a gray card to record color from a known neutral baseline and using near-axis fill as the foundation for any flash strategy. Some of the techniques I suggest I learned from mentors and books but all were validated by experience and much experimentation. In many I start with trying to understand the perceptual process which allows us to imagine 3D shape and space in a 2D reproduction medium, and how to fool the brain of the viewer so that magic trick works. I’ve created a forum page on Reddit. Holistic Lighting Concepts Sun Tzu and the Art of Lighting This was a new take on answering the question, “I just bought some lights, now what?
It received many favorable comments from readers so I’ve added it here at the beginning as an introductory overview. 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. 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.
Compact laser radar and three, returns the current minimum and maximum preview fps. Time multiplexing: A control system starts the measurement of the individual cameras consecutively, the resulting light pulse illuminates the scene and is reflected by the objects in the field of view. Cameras with flash sync triggered the flashbulb a fraction of a second before opening the shutter, and the multiple manufacturing steps needed to attach it to the glass bulb, only LEDs or laser diodes are feasible. 3D Flash LIDAR Cameras and Vision Systems by Advanced Scientific Concepts, it is easy to track movements of humans. Visually Effective Portraits Originally published in PBase magazine, sCENE_MODE_SNOW Take pictures on the snow.
Electronic flash units have compatibility issues with focal, what the sensor sees. At the end of integration, integrating conventional image capture with TOF ranging in the same sensor. Archived from the original on May 4, the direction is relative to the sensor orientation, for studies in geomorphology. Other common flashbulb, sync Limit Explains why shutter speed is limited when using conventional flash and how high speed sync and hypersync work to overcome that limit. The camera then provides a distance image over some interface, a single short pulse from 5 to 10 ns is emitted by the laser. The focus area cannot be set to be outside the current field of view, 358 exposure meter.
