Fine-Tuning and Color Temperature Approximate color-temperatures for settings other than A (auto) are given below (values may differ from color temperatures given by photo color meters): Incandescent +3 2,700 K +2 2,800 K +1 2,900 K ±0 3,000 K -1 3,100 K -2 3,200 K -3 3,300 K Fluorescent* 2,700 K 3,000 K 3,700 K 4,200 K 5,000 K 6,500 K 7,200 K Direct sunlight 4,800 K 4,900 K 5,000 K 5,200 K 5,300 K 5,400 K 5,600 K Flash 4,800 K 5,000 K 5,200 K 5,400 K 5,600 K 5,800 K 6,000 K Cloudy (daylight) 5,400 K 5,600 K 5,800 K 6,000 K 6,200 K 6,400 K 6,600 K Shade (daylight) 6,700 K 7,100 K 7,500 K 8,000 K 8,400 K 8,800 K 9,200 K * The size of the increments for Fluorescent reflects the wide variations in color temperature among the many different types of fluorescent light source, ranging from low-temperature stadium lighting to high-temperature mercury-vapor lamps. Flash Range, Aperture, and Sensitivity Flash range varies with sensitivity (ISO equivalency) and aperture. Aperture at ISO equivalent of Range 100 125 160 200 250 320 400 500 640 800 1000 1250 1600 m ft. 1.4 1.6 1.8 2 2.2 2.5 2.8 3.2 3.5 4 4.5 5 5.6 1.0-7.5 3.3-24.6 2 2.2 2.5 2.8 3.2 3.5 4 4.5 5 5.6 6.3 7.1 8 0.7-5.4 2.3-17.7 2.8 3.2 3.5 4 4.5 5 5.6 6.3 7.1 8 9 10 11 0.6-3.8 2.0-12.5 4 4.5 5 5.6 6.3 7.1 8 9 10 11 13 14 16 0.6-2.7 2.0-8.9 5.6 6.3 7.1 8 9 10 11 13 14 16 18 20 22 0.6-1.9 2.0-6.2 8 9 10 11 13 14 16 18 20 22 25 29 32 0.6-1.4 2.0-4.6 11 13 14 16 18 20 22 25 29 32 - - - 0.6-0.9 2.0-2.9 16 18 20 22 25 29 32 0.6-0.7 2.0-2.3 In programmed auto, the maximum aperture (minimum f/-number) is limited according to sensitivity (ISO equivalency), as shown below: Maximum aperture at ISO equivalent of: 100 125 160 200 250 320 400 500 640 800 1000 1250 1600 2.8 3 3.2 3.3 3.5 3.8 4 4.2 4.5 4.8 5 5.3 5.6 For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is stopped down by half an f/-stop. If the maximum aperture of the lens is smaller than given above, the maximum value for aperture will be the maximum aperture of the lens. Technical Notes-Appendix 200
