How to use a digital camera

How to use the digital camera 1. Set the parameters of the digital camera

The digital camera will provide a variety of setting parameters in the setting menu, including image resolution, aperture, focusing mode and shutter. Digital cameras need to set the image resolution. Because digital cameras have a variety of parameter settings, we should check the camera setting menu before each shooting, so as to confirm whether the parameters such as resolution and shutter are set well. If it is not set well, the photos taken will not be ideal.

note: to set the resolution of the digital camera, you should set it to the highest resolution.

For better effect, choose the highest resolution when using the digital camera, and at the same time make the subject fill the viewfinder.

If you only want to photograph a single object, such as a surgical site and a specimen, you should fill the subject in the frame.

how to use the digital camera 3. Use the illumination and flash correctly

Because the digital camera picks up images by the built-in image sensor (CCD chip), it needs proper illumination to get good results.

To create a well-lit environment to take photos, the color tone and color quality of photos will depend on the light intensity due to the characteristics of CCD chips. The light is too strong or too weak.

General digital cameras are equipped with built-in flash, which can be divided into four grades: flash, no flash, red-eye flash and automatic flash. The automatic flash file is used by the camera to detect the illumination of the photographed object to see if it is necessary to supplement the light. Flash is easy to be reflected by nearby objects, which may form some light spots on the photo.

how to use the digital camera 4. Adjustment of color temperature

There are two kinds of color films: daylight type and lighting type. The color temperature of sunlight is 54K and that of lighting is 32K K..

There is no difference in light source types when using CCD chip as sensor in digital cameras, but in order to adapt to different light source environments, white balance adjustment method can be used to correct the color temperature of photos. There are two modes of white balance adjustment for digital cameras: manual adjustment and automatic adjustment, and manual adjustment has more flexibility, so as to create better artistic effects. The color temperature of the light source has a great influence on digital photos. When taking photos with a digital camera, we must adjust the white balance according to different photographic environments.
