** 1. Aperture ** 1. ** definition and representation ** - The aperture was a device in the camera lens that controlled the amount of light that entered, and it was represented by the f-value. The smaller the f-value, the larger the aperture, and the more light entering the camera; on the contrary, the larger the f-value, the smaller the aperture, and the less light entering the camera. 2. ** Impact on the shooting effect ** - ** Depth-of-field **: A larger aperture (small f-value) can create a shallow depth of field, blurring the background and making the subject stand out. For example, when shooting close-up portraits, using large apertures such as f/1.8 or f/2.2 can make the face clear and the background blurred. A smaller aperture (large f-value) can increase the depth of field, making more images clear, suitable for shooting scenery. For example, when shooting mountains and grasslands with a small aperture of f/8 - f/16, it can keep the prospects clear. - ** Lighting **: When shooting with your hand in a dim environment, you can increase the aperture to increase the amount of light entering and ensure a sufficient shutter speed. 3. ** Adjusting Method ** - In the camera's manual mode, the aperture can be adjusted by turning the aperture ring on the camera or using the menu settings. ** 2. Shutter Speed ** 1. ** definition and representation ** - The shutter speed determines the length of the exposure time of the camera's sensor, usually expressed in seconds or minutes. 2. ** Impact on the shooting effect ** - ** Capture motion **: Fast shutter speed can freeze instant movements, suitable for shooting sports scenes. For example, shooting 100m runners requires a shutter speed of 1/1000s or faster. Slow shutter speed can create motion blur effect and express dynamic feeling. For example, when shooting night traffic, using a few seconds of slow shutter speed can make car lights form a track. However, when using a slow shutter speed, you need to pay attention to the stability of the camera. You can use a tripod or find a stable support to avoid blurring the picture due to hand shaking. 3. ** Adjusting Method ** - In manual mode, use the shutter speed dial or menu settings to adjust the shutter speed. ** 3. Photosensitivity (Iso-sensitivity)** 1. ** Concepts and Function ** - The higher the value, the more sensitive the camera was to light, but it would increase the noise. 2. ** Impact on the shooting effect ** - ** Low USB (e.g. 100 - 200)**: It is suitable for shooting in a well-lit environment. It can obtain clearer photos with less noise. - ** High USB (e.g. 800 or above)**: It is suitable for shooting in low-light environments, but it may cause noise in the photos. The high sensitivity performance of modern cameras was constantly improving, and some high-end cameras could maintain good image quality even at a higher CPU. 3. ** Adjusting Method ** - You can find the option to set the camera's settings in the camera's settings menu. Choose the appropriate value according to the lighting conditions of the shooting environment. When the lighting is good, choose the low value. When the lighting is not good, you can raise the value appropriately. ** 4. Color temperature (white balance related)** 1. ** definition and cause ** - Different light sources would affect the color temperature of the photo, causing the photo to be biased. The color temperature was a unit of measurement that indicated the color composition of light. 2. ** Impact on the shooting effect ** - If the white balance was not set properly, the screen would have color cast. For example, under different light sources such as sunlight, incandescent lamps, and fluorescent lamps, the color of the light would be different. 3. ** Adjusting Method ** - Find the white balance option in the camera settings menu and choose the appropriate white balance mode according to the shooting environment, such as "Sunlight","Cloudy Day","fluorescent light", etc. You can also use custom white balance. You can set the accurate white balance by shooting a piece of white paper or gray card to adjust the color of the photo to ensure that the white object still looks white under different light sources.

There will always be a lamp in life that brings us warmth.

Lights play a very important role in our lives. They are not just sources of illumination but also symbols of warmth. In our daily life, there is always a light that brings us warmth.
