#拍风光常提到 what "stacking method" means ##长文创作激励计划##头条创作挑战赛#
1、深度合成（Focus Stacking）：
Depth compositing is primarily used to extend the depth of field, especially in macro photography or landscape photography that requires sharp focus from foreground to background. The photographer takes a series of photos, each focusing on a different plane, and then uses software to combine them to get a single photo with a clear frame in its entirety.
2、降噪堆栈（Noise Reduction Stacking）：
When shooting in low light conditions, high ISO settings can introduce a lot of noise. With the stacking method, multiple photos of the same scene can be taken and then averaged, significantly reducing noise levels.
3、长时间曝光模拟（Long Exposure Simulation）：
The stacking method can also be used to simulate the effects of long exposures, such as smooth water surfaces or flowing clouds. By taking multiple short exposure photos and then composing them using a stack mode such as Average or Median, you can achieve a visual effect similar to that of long exposures, while avoiding the problems that can come with long exposures, such as overheating or light pollution.
4、动态范围扩展（HDR Stacking）：
To capture the full details of a high-contrast scene, such as the sky and ground at sunrise or sunset, the photographer takes a series of photos at different exposure levels and stacks them into a single HDR (High Dynamic Range) image with a wider dynamic range.
5、星轨堆栈（Star Trail Stacking）：
In astrophotography, the stacking method is used to create star trail images. By taking a series of long-exposure photos and then stacking them together, it is possible to show the trajectory of the stars moving in the night sky.
When doing stack compositing, you often need to keep the camera fixed in the same position, which often means using a tripod. In addition, post-processing software such as Adobe Photoshop, Helicon Focus, Focus Stacker, StarStaX, etc., provides stacking capabilities to help photographers achieve the desired effect. The stacking method is a powerful tool in landscape photography to enhance photo quality and create unique visual effects, but it also requires patience and precise technique to execute.
