소개
The Bower SFDRF Digital Macro Ring Light Flash is designed to provide convenient and creative lighting for various close-up photography applications, including documents, medical subjects, dental work, nature, and small objects. This unit utilizes a circular light source to deliver even, shadow-free illumination, which is particularly beneficial at short working distances where built-in or conventional flash units may be ineffective. Its two-piece design ensures ease of handling and camera balance, making it a versatile tool for both digital and 35mm SLR cameras.

작동 지침
- 전원 켜기/끄기: Use the multi-function switch on the control unit to turn the flash on or off.
- 시험발사: The multi-function switch also includes a test fire function. Press it to manually trigger the flash and confirm operation.
- 모드 선택: The SFDRF offers a choice of manual or auto-sensor control. Select the desired mode based on your photographic needs. In auto-sensor mode, the flash adjusts its output based on ambient light conditions.
- 플래시 지속 시간: The flash fires as fast as 1/50,000th of a second, effectively freezing movement for sharp macro photography.
- Creative Lighting Control: For situations where shadow-free images are not desired, the flash head can be detached from the lens and aimed manually to achieve creative lighting effects.
- 삼각대 장착: The control unit features a built-in tripod socket, allowing it to be mounted to positioning arms or other supports for off-camera flash setups.
- Exposure Management: Due to the powerful output of the ring flash, it may be necessary to adjust your camera's exposure settings (e.g., aperture, ISO) to prevent overexposure, especially in close-up situations. Consider using neutral density (ND) filters if your camera's minimum ISO and maximum aperture settings still result in overexposed images.
유지
- Keep the flash unit clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- When not in use for extended periods, remove the AA batteries from the control unit to prevent leakage and potential damage.
- Store the flash in a dry, cool place, away from direct sunlight and extreme temperatures.
- Handle the unit with care, as its construction is primarily thin plastic. Avoid dropping or subjecting it to strong impacts.
문제 해결
- 플래시가 터지지 않음:
- 배터리가 올바르게 설치되었는지, 그리고 충분한 충전량이 있는지 확인하십시오.
- Ensure the control unit is securely mounted on the camera's hot shoe and the cable connection to the flash head is firm.
- 플래시 전원이 켜져 있는지 확인하십시오.
- Images are Overexposed (Washed Out):
- The flash output may be too strong for your current camera settings. Adjust your camera's aperture to a smaller opening (higher f-number), lower the ISO sensitivity, or increase the shutter speed (within your camera's flash sync speed limits).
- Consider using neutral density (ND) filters on your lens to reduce the amount of light reaching the sensor.
- Focusing Issues with Autofocus:
- The cable connecting the flash head to the control unit may exert tension, potentially affecting lens focus. If experiencing issues, try to manage the cable's position to minimize tension or switch to manual focus.
