To reset the Nikon D90 to its factory settings, go to the Setup menu, select 'Reset Shooting Options' and 'Reset Custom Settings'. Confirm the action to restore the default settings.
To clean the sensor, use the camera's 'Clean Image Sensor' function found in the Setup menu. For manual cleaning, use a blower to remove dust. If necessary, use a sensor cleaning swab and appropriate cleaning solution.
Check if the lens is set to 'Auto Focus'. Ensure the focus mode on the camera is appropriate for your subject. Clean the lens and camera contacts. If issues persist, a firmware update or a service check may be required.
To extend battery life, reduce LCD screen usage, disable unnecessary features like VR and Live View, and use the camera's power-saving mode. Always carry a spare battery for extended shoots.
Check the battery charge and ensure it is inserted correctly. Inspect the battery contacts for dirt or damage. If the problem persists, try using a different battery or contact Nikon support.
Download the latest firmware from Nikon's official website. Transfer it to a formatted SD card, insert the card into the camera, and follow the instructions in the Setup menu to update.
For the best quality, set the image quality to RAW. If storage is a concern, JPEG Fine offers a good balance between quality and file size.
Use a lower ISO setting and a tripod to stabilize the camera for longer exposures. Enable noise reduction settings in the camera menu and consider using post-processing software to reduce noise further.
Start by setting the ISO based on lighting conditions, adjust the aperture for depth of field, and set the shutter speed to freeze or blur motion as needed. Use the camera's exposure meter as a guide.
You can transfer photos by connecting the camera to the computer using a USB cable, or by removing the SD card and using a card reader. Use Nikon's ViewNX 2 software for seamless transfer and management.
