How to delay taking pictures

First, preparation before shooting You need to prepare a tripod, a camera and take hundreds of photos. If you are shooting mobile phone time-lapse photography, you may need to prepare a slide rail (you can also move the tripod to shoot, but it needs to be super stable later, otherwise the picture will shake); If it's just time-lapse photography in a fixed position, just prepare a tripod. Because time-lapse photography captures the change of light, it is recommended that you use a wide-angle lens to shoot. The scene is large and the ambient light changes dramatically. Because time-lapse photography takes a long time and the light changes greatly, especially from day to night, it is best to shoot with a large aperture lens to ensure the image quality. Second, the camera sets the exposure mode: aperture priority (fixed aperture value and sensitivity, let the camera adjust the shutter value according to the change of ambient light) White balance: manually adjust the K value, and the automatic white balance will change due to the change of light, resulting in color cast. Focus: focus manually, don't shoot with autofocus. Photo format: RAW format shooting, leaving more space for later operation. Interval Timer (Canon): Find "Interval Timer" in the menu and adjust the interval time to 5 seconds, 7 seconds, 8 seconds, etc. I usually have a 7-second break. Adjust the number of shots to infinity, and then confirm shooting.
