Photographic equipment maintenance system

Answer 1

The following is a photographic equipment maintenance system:

** 1. Cleaning **
1. ** Cleaning tool selection and precautions **
- Cleaning the photographic equipment should use suitable tools, such as air blowing, lens cloth, lens cleaner, cotton swabs, wet towels, etc. It is strictly forbidden to use mouth blowing, finger wiping, or other unprofessional tools to avoid scratches or pollution.
- Cleaning liquids, wet towels, and other cleaning supplies should not be overused, and expired or deteriorated cleaning tools should not be used.
2. ** Cleaning sequence and steps **
- Cleaning should be done in a certain order, generally from outside to inside, from big to small, from light to heavy.
- Cleaning the camera body: First use the air to blow off the dust and hard particles on the surface, then wipe the entire surface of the camera body with a wet towel. For parts that are difficult to clean, such as gaps and bayonet, you can use cotton swabs and cleaners for fixed-point cleaning.
- Cleaning the lens: First use air to blow off the dust and hard particles on the lens, then use the lens cloth and lens cleaner to carry out a deep cleaning. Wrapped the cleaning cloth with lens agent on your fingers, and then wiped the lens from the center of the lens in the same direction at a constant speed. For lenses that are deep inside the bayonet, you can use a microfiber lens cloth wrapped in a cotton swab to clean them.
- [Cleaning of the sensor: It must be done in a dust-free environment and must be done very carefully.] First, check if there is any dust or stain on the sensor (set the camera to full aperture, the highest IS value, manual focus infinity, and take a photo against a pure white background. Then, enlarge it to check if there are any black spots). If there is dust or stains, you can use a professional sensor cleaning kit to gently and quickly wipe it according to the instructions. If you are not sure if it can be operated, you should send it to a professional after-sales service. At the same time, cleaning should be avoided in a strong wind or dusty environment. Do not spray any liquid directly on the camera or lens (indirectly).

** 2. Storage **
1. ** Storage location and container selection **
- The photographic equipment should be stored in a suitable place and container, such as a waterproof box, a waterproof cabinet, a sealed box, etc. Do not place the equipment in direct sunlight, high temperature, high humidity, electromagnetic interference, or dusty places.
2. ** Storage method and posture **
- Storage: Turn off the camera and remove the battery (if not used for a long time). Place it in a waterproof box covered with a soft cloth or styrofoam. When possible, the camera could be stored together with the commonly used lens, and a U-shaped inner lining layer (foam board would also work) could be added to the connection to support the lens.
- Single lens storage: Lock the lens hood upside down and cover the front and rear covers. Place the lens upside down in a separate space in the moisture proof box. At the same time, he adjusted the focus ring to infinity and shrunk the zoom lens to the shortest position, fixing it with the lock button.
- Storage of batteries: Batteries of different brands or models cannot be mixed or stored together, and the humidity in the moisture proof box or cabinet should be checked regularly (generally, it is recommended to store them at a humidity of about 50%). If the moisture absorption card or the drying agent is used, it must be replaced or disposed of in time; if the electronic moisture proof box or moisture proof cabinet is used, it must be powered on at all times to avoid power failure.

** 3. Protection during use **
1. ** Screen Protection **
- It was to prevent fingers from touching the lens to prevent fingerprints and grease from affecting the paint coating and imaging of the lens. avoid contact with saliva or water stains, and avoid contact with pink gloves (during daily shooting, it is recommended to use bare hands or gloves that have never touched the patient). Move quickly when changing the lens, avoid the wind and dust, and cover the lens cover in time when not in use. The lens can be protected by adding a UV-lens (Ultraviolet filter) and a hood.
2. ** Airframe Protection **
- Water Repellent: When water flows into the interior of the camera, it is easy to cause a short circuit. The temperature difference is easy to produce condensation. When shooting in low temperature environments, it is recommended to wear a cold-proof thermal cover for the camera. When the camera is not in use, put it in a special drying box or place a drying agent in the locker to avoid moisture.
- [Protect from dirt: Move quickly when changing lenses. Face the camera down. Pay attention to avoiding the wind to prevent dust from entering the camera.] Do not wear pink gloves during daily clinical imaging, and do not cross infect the patient.
- Shock absorption: When shooting, try to hang the camera around your neck to prevent the camera from falling due to instability. When placing the camera, find a stable place to place it to prevent the camera from falling off due to unstable support.
- LCD screen protection: To prevent the color LCD screen from being scratched by hard objects, you can consider using a protective sticker.
- Protection of the camera card: Do not hot-plug it, do not plug the camera card when it is turned on, so as to avoid damage to the digital products and data loss. It was recommended to have an extra camera card, just in case. A large number of clinical images were recorded in the camera card, and it was necessary to develop the habit of backing up regularly. When the memory card is not in the camera, pay attention to prevent bending, to avoid falling and heavy blows. When inserting the camera card, aim at the card slot. Don't be violent or impatient. Don't damage the card slot interface or bend the camera card pin.
