Shoot in Manual Mode, the camera can't predict or compensate for the light the strobe outputs. In Manual Mode you will be able to fully adjust both your aperture and shutter speed to capture the photo you want. To do this turn the Tetra's mode dial to the A/S/M setting. Enter the camera's menu and set the preferences from the default A mode to M mode. Only when you see a "M" displayed in the camera's LCD monitor are you in manual mode. Only in manual mode will an external strobe fire consistantly.

Review your photo immediately after you take it. If the image is not the shot you want, make a correction to the aperture, shutterspeed, composition, or strobe and shoot again. Repeat this process until you get the shot you want. This "Shoot-Review-Adjust-Shoot" sequence allows you exploit the instant feed back advantage that digital cameras offer.

First picture: Ugh! Strobes are not lighting the subject	Second Photo: Strobes are correctly positioned.

If you want to view your most recent photo without leaving the "Recording Mode", press the display button twice quickly. This accesses the "Quick Display" mode without having to turn the Mode Dial. You can scroll through your photos to review, delete, or write-protect them. Then press the shutter release once to return to "Recording Mode". After you evaluate your photo, make necessary aperture, shutter speed, strobe, or composition changes and keep shooting.

If you forget your camera's settings, press the menu button twice (on then off) and the LCD displays the current camera settings for two seconds. For example, if you can't remember if you're shooting in macro mode or not, press the menu button twice and the LCD reveals the macro icon if you're indeed in macro mode.

The macro range of the camera is 8" to 31". If you are this close to your subject turn on the camera's macro mode regardless of which lens you are using. Note: actual minimum focus distance varies between Tetra lens, but can be as close as 3" with the macro lens.

If you have strong ambient light and don't need strobes, you may be able to take advantage of the camera's "Burst" feature.
"Burst" mode takes five photographs in three seconds once the shutter release is pressed once. You're ready to capture a great series or a fast moving sea creature.
