The document summarizes a workshop on studio photography. It discusses principles of artificial lighting including using it to control light and sculpt with light. It describes the basic goal of studio lighting to recreate natural light highlights and shadows. It then explains the basic four light studio setup including key, fill, background, and accent lights. Finally, it discusses different types of portrait lighting like Rembrandt, loop, butterfly, and split lighting.

3. Principles of artificial lightingWhy use artificial light?Lack of adequate natural lightTake control of the lightMake a photograph; don’t just take it.Shooting with artificial light is like: “Sculpting with LIGHT”

4. Basic goal of artificial lightingBring out the 3D quality of the subject(s)By reproducing the highlights and shadows as produced under natural light

5. By revealing surface texturesBasic Studio LightingCategories of studio lightBasic four light setupStudio lighting tools

6. Categories of studio lightContinuous+ Cheap + See what the light is doing - Produces more heat than light - Not balanced to daylightFlash+ Balanced to daylight (5500K)+ Saves power

7. Basic four light setupKey Light(M)The main light source/ brightest light sourceFill light (F)Soften the shadows formed by Key lightBackground light(B1)Lights background and not the subjectAccent lights(H, B2)Adds a rim light to separate subject from background.Also called “kicker light”

8. Steps in preparing lighting setupDecide on general effectvisualize; determine type/direction/angle of light2. Add the key light(s)- create dominant set of highlight & shadows3. Place the fill lights- Adjust light ratio to obtain desired effect4. Separate subject from background - Add background light - Add kicker light (optional) - Subject should not be close to background (min 5 feet) - Lights should not add to any secondary highlight or shadows5. Make final adjustments- take sample shot, analyze and readjust - look out for unwanted highlights/shadows, catchlights

17. Exposure in studio lightingShutter speed in camera has no control on exposure as your camera cannot shoot faster than your camera SYNC speed, it is 1/200.Exposure can be controlled by :1. The power of the light2. Aperture of the lens3. ISO setting

18. How to control studio light powerControls on Light system ( Full, ½, ¼, 1/8 )Distance of light from subject. Inverse Square Law applies here ( so if you move your subject from 3 feet away to 6 feet away, your light power will reduce by 4 times or you will need four times more light)

19. Aperture and f stopsFor aperture control under studio lights, same principle applies.Exposure halves by increase in each f-stop f/8, Full power @ ISO 200 will give same exposure as f/5.6, ½ power @ ISO 200The full f stops are2.8 4 5.6 8 11 16 22
