Just bought Canon 5D2 and 24- 105. Playing SLR for the first time, I can't shoot. How do I set the parameters for shooting people and landscapes?

1, regardless of the landscape of the characters, the first thing is to do a good job of accurate exposure. Digital cameras have three values to control exposure. Iso value of aperture shutter.

2. Try to lower the iso to 100 during the day and to 1653 at night, because the higher the ISO, the worse the imaging effect, but the better the photosensitivity, the less light is needed.

3. The aperture is equivalent to determining the size of the entrance hole. The larger the f value, the smaller the f value and the smaller the aperture. Generally speaking, the scene of a large scene tends to a small aperture (the greater the F value), which can keep more details. However, a large aperture is also acceptable. If you can shoot people, you can shoot people with a large aperture or a small aperture.

4, shutter control is very important, if you shoot by hand. Try to keep the shutter above 1/60 to ensure that the picture will not shake. Long exposure is common when shooting water and scenery, but tripod and nd filter are needed. Shutters are usually above1s.

5, a photo and a protagonist. When composing a composition, we must highlight the subject, keep the background as simple and unified as possible, and pay attention to the subject of the photo to avoid being "eye-catching" by the background.

Matters needing attention in using SLR camera

1, don't drop and physically smash the camera. A camera is a precision instrument. If you do this, a small piece of metal may fall off and the camera may not be used.

Take your camera, especially when playing by the water, don't fall into the water, because the camera is not waterproof.

Don't put the camera in the TV cabinet or next to the TV, and try to avoid the place near the strong magnetic field.

4. Don't put the camera in a place with extremely high or low temperature, such as the air outlet of air conditioner or the car with direct sunlight.

5. Don't clean the body and lens with organic solution, just blow away the dust with air.

6. Don't touch the electronic contacts of the camera or lens with your hands. When you see dust on the electronic contact of the camera, don't wipe it by hand, but use a rag or paper, because there is a lot of salt on your hand, which is easy to corrode the contact.

7. If you don't use the camera for a long time, please take out the battery and put the camera in a well-ventilated place.

I haven't used my camera for a long time. When using it, I must personally test all the functions of the camera to ensure that it can work normally and avoid the trouble of not using it.
