Core technology. Stack in landscape photography-Brother Lei who loves photography.

Body and soul must have one on the road. In today's fast-paced life, travel is undoubtedly one of the shortcuts to relax and broaden your horizons. So how to make a movie "I'm glad you came" during the trip? In this book, you will get all the knowledge points and stimulate your creative inspiration. From the early preparation, on-site shooting to the later thinking, the birth process of each blockbuster is described in detail.

The so-called superposition technology refers to the superposition of countless short-time shutter photos taken in the early stage through the later stage technology to obtain the picture effect of long-time exposure shooting, such as flowing clouds, flowing streams, urban traffic at night and so on. By using the appropriate layer blending mode to overlay in Photoshop, you can also blend scenes of different time periods together. In addition, using post-stack technology instead of long-time exposure not only avoids the use of filters, but also reduces the thermal noise caused by long-time exposure. The superposition of static images can also eliminate noise and unnecessary content, thus improving the image quality. Next, I will explain in more detail how to apply stack technology in photography with examples.

Technical points

Technical points

1. Taking multiple photos with aperture priority camera mode can make the light of each photo transition naturally.

2. Keep the tripod stable, and ensure that the tripod and camera can't vibrate and move during continuous shooting, which is beneficial to the alignment of multiple photos in the later period.

3. Set the camera interval time reasonably according to the wind speed and shutter speed. For example, if the wind speed is too fast or the interval is too long, the superposition of flame clouds will be unnatural; If the shutter speed is too slow, it may cause the camera to take a photo every two intervals (for example, the camera shutter speed is 1.5s, and the interval shooting is set to 1s, so that shooting can be triggered every two intervals), and the interval time is too long, which will make the superposition effect unnatural.

4. When shooting continuously, you must use manual focusing, that is, keep the lens in the initial focusing state to shoot, so that the layers can be aligned smoothly and the superposition can be completed later.

5. When shooting the lights turned on in the city after sunset, underexposure can be properly carried out to ensure that the lights of urban buildings will not be overexposed, so that the superimposed building lights will be more beautiful in the later period.

Seda Lightning Night

 O 100, aperture f/ 1 1, focal length 14mm, shutter 1/30s.

This film was shot on the hill opposite Sedafo College. Thunderstorm suddenly struck before sunset, and this thrilling Sedaver lightning night was shot at the end of work.

When I was in Beijing, I went to the Great Wall dozens of times to shoot arrows. "Snow Arrow Buckle" was shot at four o'clock in the morning before the snowstorm in Beijing.
