2 Lighting Applications
16 Lighting Applications

3 Objectives Recall the techniques and characteristics of both “classic” and “natural” lighting. Explain different method and applications for lighting backgrounds. Identify effective solutions for common lighting problems. Recall effective methods to light interior and exterior night scenes. Identify effective techniques for lighting frequently encountered assignments.

4 Lighting Subjects Classic studio lighting “Natural” lighting
Lighting backgrounds

5 Classic Studio Lighting
Often called three-point lighting Three lights on subject: Key light Fill light Rim (back) light Background light

6 Key Light Provides main illumination Placed at about 4:30 on clock
15°−30° higher than subject’s face Throws distinct shadows on subject Goodheart-Willcox Publisher

7 Key Light Placement Plan Elevation Effect Goodheart-Willcox Publisher

8 Fill Light Fills in shadows created by key light
Placed opposite key light Plan Elevation Effect Goodheart-Willcox Publisher

9 Rim Light High and behind the subject
Brightness depends on lighting style Plan Elevation Effect Goodheart-Willcox Publisher

10 Background Light Usually motivated
Subject should be slightly brighter than background Plan Elevation Effect Goodheart-Willcox Publisher

11 Complete Lighting Setup
Figure 16-6 (include labels) Plan Elevation Effect Goodheart-Willcox Publisher

12 “Natural” Lighting Key factor is soft light
Spots and broads can be diffused Large sources are easier to work with

13 Rugged vs. Glamorous Lighting
Rugged lighting Exaggerates planes and angles of the face Emphasizes skin texture Glamorous lighting De-emphasizes facial modeling Moderate shadows Minimizes skin texture

14 One-Light Design Subject should be close to background
Light placed at about 8:30 Plan Elevation Effect Goodheart-Willcox Publisher

15 Two-Light Design Key and fill lights Second softlight provides fill
Plan Elevation Effect Goodheart-Willcox Publisher

16 Three-Light Design Key, fill, and background lights Better control
Plan Elevation Effect Goodheart-Willcox Publisher

17 Lighting Backgrounds Light subjects and backgrounds separately
Purposes for lighting backgrounds Exposure Texture Depth Intensity

18 Lighting Small Interiors
Cramped quarters Insufficient power supplies Amperage Wattage Voltage Background spill Ceiling bounce Hiding lights Goodheart-Willcox Publisher

19 Hiding Lights in Small Interiors
Taped to a wall Clamped to a partial wall Clamped to a chair Lowel Light Inc.

20 Lighting Large Interiors
Cannot be fully lit with instruments from a small production kit Strategy: Light subjects, not the space Break action into parts Light and shoot each part separately Start with wide shots Re-light for close shots

21 Lighting Plan for Large Area
A broad lights most of the background Key lights aimed at each action area Two broads add overall fill light Completed light plan Goodheart-Willcox Publisher

22 Start with the Wide Shots
Light action areas to be included in wide shots Light background fully Add general fill light

23 Light the Close Shots Light the subjects Light the background

24 Lighting Moving Subjects
Need to light all action areas Setup for wide shots usually works well Goodheart-Willcox Publisher

25 Exteriors Use sunlight in good weather Use reflectors
Soft reflectors for even coverage Aluminum reflectors for long throw White reflectors for fill Screens preserve natural light patterns

26 Lighting Problems Hard-to-light subjects Specialized light sources

27 Subject Problems Heavy faces Thin faces Darker complexions
Bald subjects Subjects wearing glasses

28 Heavy Faces Highlight center of face Use vertical barn doors
Place light at about 6:00 Place soft fill lights at 3:00 and 9:00 Goodheart-Willcox Publisher

29 Thin Faces Make sides of face brighter than center
Use soft key lights at about 6:00 and 9:00 May be able to omit key light entirely Goodheart-Willcox Publisher

30 Lighting to bottom half reduced
Darker Complexions Can create contrast problems Use barn doors and half screens to block or moderate light Straight lighting Lighting to bottom half reduced Goodheart-Willcox Publisher

31 Bald Subjects Best handled by makeup department If no makeup
Neutral powder eliminates reflections If no makeup Move lights up and farther to one side

32 Subjects Wearing Glasses
Move light out of incidence/reflection path 45° or greater Reflections from softlights may be okay

33 Specialized Light Sources
Include practicals and environmental light sources Rarely in the right place Rarely operating at the right intensity Establish the light source by showing it on camera Replace light source with more controllable light

34 Practicals Handling depends on lighting style
Naturalistic/expressionistic Excess contrast acceptable Realism/pictorial realism Establish practical, then use video light Balance visible light by adjusting intensity

35 Moving Light Sources Simulate practical light when not on screen
Flashlight Small spotlight with handle Lantern Diffusion and orange filter on a broad Candle Broad and gloved hand to create flickering Flashlight beam Goodheart-Willcox Publisher

36 Firelight Place broad very low Gel with orange filter sheet
Wave “grass skirt” cookie in front of light Goodheart-Willcox Publisher

37 Signs Gel a light with appropriate color
Move flag rhythmically in and out of light path for blinking light

38 Electronics Place small lights low Use pale blue or green gels

39 Lighting Interior Scenes at Night
Use low-key mode Establish practicals Control window light Light for highlights

40 Fake the Darkness Establish light level Establish “night”
Synchronize scene lights Goodheart-Willcox Publisher

41 Lighting Exterior Scenes at Night
Light only important action areas Back-cross lighting Rake the background Look for motivation Use atmosphere to scatter light Goodheart-Willcox Publisher

42 Lighting at “Magic Hour”
Brief time before sundown Light qualities look attractive on screen Requirements Capture all footage in brief time Manually reset white balance frequently

43 Day-for-Night Lighting
Make daytime shots look like night Shot recorded normally Completed day-for-night version Goodheart-Willcox Publisher

44 Guidelines for Day-for-Night Lighting
Set white balance for incandescent Use back-cross lighting Frame off the sky Include incandescent light Goodheart-Willcox Publisher

45 Day-for-Night Lighting Setup
Goodheart-Willcox Publisher

46 Lighting Assignments Interviews Stand-up reports Compositing
Small objects and areas Graphic materials Internet lighting

47 One-Person Interviews
Softlights Small spot as rim light Lighting setup Closeup of the subject Goodheart-Willcox Publisher

48 Two-Person Interviews
On-screen interviewer must be lit Lights for both people placed outside frame Single shots of interviewer Subject, over the interviewer’s shoulder Reverse setup of the interviewer Lighting setup Goodheart-Willcox Publisher

49 Cheating Moving a subject between camera setups Invisible to viewers
More working room Separate subject and background Better-looking background Invisible to viewers

50 Stand-Up Reports Presented by reporters standing at the scene
Single technician acts as cinematographer, lighting director, and sound recordist

51 Reflector plus small on-camera key light
Daytime Reports On-camera front fill light highlights reporter’s face Reflector provides supplementary light Reflector alone Reflector plus small on-camera key light Goodheart-Willcox Publisher

52 Nighttime Reports On-camera light provides illumination
Battery-powered light on stand used instead of reflector One-light setup A second light added, on stand On-camera light offset for better modeling Goodheart-Willcox Publisher

53 Compositing Keep lighting uniform Even background lighting
One softlight at each side Foreground/subject lighting Place subjects as far forward as possible Classic spotlight lighting in foreground Keep foreground light off background Place light high and to the side

54 Lighting for Compositing
Spotlights with diffusion evenly wash the background Subject is as far in front of the background as practical An alternative setup: soft lighting on both subject and background Manfrotto, USA

55 Small Objects and Areas
Most professional lights are scaled for larger subjects Techniques: Tabletop cinematography Tent lighting Ring lights

56 Tabletop Cinematography
Goodheart-Willcox Publisher

57 Tenting Goodheart-Willcox Publisher

58 Ring Lights Used when other lighting techniques are not practical
Surround lens completely Throw only one soft shadow Litepanels, Inc.

59 Graphic Materials Scan or record video Place material on flat surface
Vertical Horizontal One light on each side of material Aim lights at 45° angle to reduce reflections Goodheart-Willcox Publisher

60 Internet Lighting Use classic four-source lighting
Use rim lighting to sharply separate subjects from background Aim for high key lighting Keep background lighting simple
