26 Adjusting camera settings For SeaLife digital cameras, set the camera to External Flash mode . For more details r efer to your SeaLife camera instruction manual. For non-SeaLife cameras , set-up the digital exposure settings as r ec- ommended here. ISO Choose and set an ISO appropriate to the conditions you expect on your dive. The deeper you go[...]

27 Y ou notice the deeper you go, the lower the visibility . The darker the light conditions are, the higher the ISO. This makes your camera mor e sensitive to light and will serve to compensate for the absorption of light at depth. Exposur e V alue (EV) also allows you to increase, or decrease, the camera’ s light sensitivity . Increase EV to br[...]

28 White Balance (WB) . This setting will match the color temperature (not heat) of the light source to your camera’ s sensor . Before using the SeaLife Digital Flash set your WB to AUTO. Set White Balance to FLASH, if available. Manual exposur e contr ols Most digital cameras also offer a manual mode that allows you to adjust the aperture and sh[...]

29 Using the Digital Flash variable power adjustment : If the test image is over exposed (white or washed out colors), turn the power adjust- ment clockwise to the first “bar” and take another picture.

31 VI. Tips fr om the Pro’ s STEPHEN FRINK Stephen Frink is the world’ s most widely published under- water photographer . With a career spanning over two decades, his photos have appeared in a wide variety of dive journals and magazines world-wide, and he has provided stunning imagery for hundreds of pr omotional campaigns. For more informatio[...]

32 Still, there ar e a few principles that can make even digital photography better: STEPHEN’S TIP 1: MINIMIZE BACKSCA TTER Backscatter is the most important variable in point-and-shoot photog- raphy because the strobe is near the lens with most systems. Particles in the water are fr ont-lit by the flash and appear as specks of “back- scatter .[...]

33 • One important advantage with the SeaLife Digital Flash, is that when particles are illuminated, it is with rim-light rather than fr ont-light, and the backscatter effect is minimized. • Position your strobe high and to the side, pointing down to the subject. STEPHEN’S TIP 2: SHRINK THE WA TER COLUMN W ater — 800 times denser than air ?[...]

34 STEPHEN’S TIP 3: CHOOSE THE RIGHT SUBJECT Because the best results will be obtained when working close, ther e is a limited universe of subjects possible with these cameras. With the normal lens on a SeaLife digital camera a full-figure shot of divers must be taken from eight to 10 feet away , making the shot inevitably mono- chromatic blue. A[...]

35 STEPHEN’S POINT -AND-SHOOT WORKSHOP This series of four photos taken with the SeaLife flash shows the tremendous ef fect water has on color saturation. In the first photo (above right) the subject is approximately five feet away . Note the dull, muted colors. In the second photo (above right), from about three feet away , colors are mor e auth[...]

37 • Get closer with your strobe. • Shoot in deeper water or on darker days. • Use manual control to make backgr ounds darker and strobe brighter • When shooting close, use a fast shutter speed such as 1/500 th second. • Use the smallest aperture on your camera (usually ar ound an f8.) • T ake a picture; adjust the strobe power setting [...]

38 • If you fall forward when kneeling, move your weights towar d your back. • If you use integrated weights, put part of them on a belt on your back to prevent falling forwar d. CA THY’S TIP 3: Get close for better color • Use wide add-on lenses or the widest zoom setting to allow you to get close to medium and lar ge subjects. • Use clo[...]

39 • Aim your strobe straight out, rather than tilted down, for subjects beyond a foot from the camera. • Extend your strobe as far away fr om the lens as possible to reduce backscatter . CA THY’S TIP 5: Set the white balance for cloudy to increase color . Experiment with other settings for your conditions. For example, the flourescent settin[...]

41 JOHN’S TIP 3: Adjust the speed of your sensor (ISO) to be more sensitive (higher ISO) the deeper you go. If your subject is at 3 feet (1m) or less, never set your camera’ s ISO above 200 ISO. JOHN’S TIP 4: Always try to use a horizontal or up angle when capturing images with your camera. These angles should allow you to capture a beautiful[...]

42 VII. Car e and Maintenance 1. After each use, Digital Flash and camera housing must be soaked in fresh water immediately to remove salt and dirt . Keep housing and flash sealed. 2. Never use any deter gents, cleaners, solvents or chemicals to clean the flash. The mask bucket on a boat is full of deter gent – do not use this. 3. Let the water d[...]

43 5. Always keep the compartment cover O-ring clean, dry and free fr om obstructions. Latch and inspect the compartment door . 6. Inspect O-ring for cuts, tears, dirt or other damage. Clean O-ring with damp cloth and allow to dry . Replace O-ring if damaged. 7. Replace all worn or damaged parts. Contact your local dive shop, or the SeaLife website[...]

44 VIII. GLOSSAR Y ISO. International Standards Organization . This term ISO relates the ability (speed) of the camera’ s sensor to accept light. Higher the ISO the more sensitive the camera is to light r esulting in a brighter , but more grainy image. Exposure V alue (EV). EV setting controls the camera sensitivity to light. A positive EV means [...]

45 Shutter speed. The amount of time the camera shutter opens to permit light through the apertur e and on the image sensor . Fast shutter speed (125/sec and above) will stop action. Slower than (60 th /sec) will be blurry , unless the camera is held very steady or on a tripod. As a general rule, use shutter speed values between 1/90 to 1/500 for u[...]

46 IX. T rouble Shooting Guide 1. Digital Flash does not fire when switch is turned from “ON” to “TEST .” a. W ait until the green flash-ready light is on.

Refer to your camera instructions for problems r elated to the camera. d. Make sure the Digital Flash’ s pre-flash cancellation switch is properly[...]

48 b. Make sure flash sensor cover is covering light sensor farthest from camera. c. Refer to Flash Link instructions for correct installation pr ocedures. 4. Dark areas in your pictur es. a. Direct the flash head closer to the center of your pictur e frame to have a more even light coverage. b. Areas further away from the camera will appear darker[...]

49 e. The reflectivity of your subject will cause some ar eas to appear brighter than other areas. For example, dark coral needs mor e light than would white coral. Adjust flash intensity accordingly . f. The further the flash head is away from the camera lens, the bigger will be shadows due to the angle of light (flash) in relation to the subject.[...]

50 c. T est flash arm flexibility underwater . The flash arm will become stiffer underwater . 6. Rust accumulating around power on and test swtich. The switch is magnetic and will attract metal debris, like rust, from a shipwr eck. Clean off rust and metal debris with a brush. 7.
