This is Jack Hamm’s entire section on folds, minus a page that was repetitive so I ditched it to fit the photoset limit. If you guys like, I’ll scan more of his stuff from time to time, I have been trying to get everyone on board with him forever!
To reiterate, these scans are from Jack Hamm’s Drawing The Head And Figure.
Thank you so much mariealbertine for submitting this! :»!
Light and Shadow tutorial by Ron Lemen
Please click through the link! There’s a wealth of information that he gives in his quick write-up for this. It’s a very basic overview of light/shadow but it provides a solid foundation for the topic.
ConceptArt Thread “Theory Discussion: “Color Theory” Principles and Practice” By: fredflickstone
I originally posted some of these pictures without the corresponding concept art thread… it’s quite helpful for color theory basics :>
Have fun, keep drawing!
EDIT: SORRY!!! fixed the link!!

A Photgraphy Term Dictionary
A:
Aberration: A lens fault (problem) in which light rays are scattered, degrading the image. Different types include:
Chromatic (colors and light wavelengths), Spherical (blurring in the center of a picture), coma (edge blurring),
astigmatism (light rays focused as a line, not a point), and field curvature (plane of sharpest focus is a curved surface).
Achromatic Lens: a lens constructed of different types of glass, used to reduce chromatic aberration.
Acutance: The objective measurement of how well an edge is recorded in a photograph.
Additive process: the process of combining lights of different colors.
Aerial process: The impression of depth in a scene, created by use of haze.
Anastigmat: A compound lens; reduces optical aberrations
Angle of view: The widest angle of those light rays used by a lens to form an acceptably sharp image at the film plane. Widest when lens is set to infinity.
Angstrum: measurement of light wavelength. All that physics crap is boring.
Aperture: An adjustable circular hole centered on the lens axis. The aperture is adjusted to allow more of less light in. f/1.8 lets in more light then f/33. Think of it as a fraction. This is important.
ASA/ISO: The sensitivity rating of a film to light. The higher the number, the more sensitive. Iso 400 is good for indoor photography, for example. ASA/ISO 200 is twice as fast as 100.
Automatic Exposure (AE) control: A system found in many modern cameras which utilizes a photo-electric cell to determine the amount of light reaching the film. AE control will then set shutter and/or aperture speed for you. Many cameras will also allow you to set either aperture size or shutter speed, and the camera will change accordingly, adjusting the other to balance the photograph. This is a great setting for sports photography.
Auto Focus (AF): on many modern cameras, AF allows the photographer to point the camera at a scene, and the photo-electric cell in the camera itself focuses the lens faster then many could focus manually. Handy for sports and wildlife photography, when you don’t have tons of time to focus for a shot.
B:
Back Lighting: lighting behind a subject, directed towards the camera.
Barrel distortion: A lens aberration that distorts an image. Straight vertical lines bow outwards. Barrel distortion is found using a fish-eye lens and can be used to great effect.
Bas-relief: A method of producing images that stand out. Produced by sandwiching a positive and negative of the same image slightly out of register.
Bayonet mount: a type of fitting enabling lenses to be mounted on the camera body quickly and easily.
Bee gun: A hand-held smoke gun used to produce special effects smoke by burning charcoal and incense.
Bounce Flash: light from an electronic flash bounding off a reflective surface such as a wall, ceiling or white umbrella- produces a softer more diffused illumination
Bracketing: shooting the same picture three times: one underexposed (high aperture), one at correct exposure, and one overexposed (low aperture).
Brightness: “The subjective impression of luminance.” Wow, who the fuck came up with that definition? Hahaha.
