Introduction

Image Stacker is a versatile and user-friendly Windows program that allows users to combine multiple images into a single image using various blending methods. This tool is particularly useful for photographers and developers who need to create long exposures, star-trail images, and reduce digital noise in their images. In this article, we will delve into the features and benefits of Image Stacker, as well as provide a step-by-step guide on how to use it.

What is Image Stacker?

Image Stacker is a Windows program that can be run from the command-line and easily incorporated into scripts and batch files. This flexibility makes it an ideal tool for developers who need to automate image processing tasks. The program combines multiple images into a single image using one of several different blending methods, including:

Average: This method calculates the average pixel value of each image and combines them into a single image.
Median: This method calculates the median pixel value of each image and combines them into a single image.
Maximum: This method selects the maximum pixel value of each image and combines them into a single image.
Minimum: This method selects the minimum pixel value of each image and combines them into a single image.
Weighted Average: This method calculates a weighted average of each image based on their exposure times.

Benefits of Image Stacker

Image Stacker offers several benefits to photographers and developers, including:

Long Exposures: Image Stacker allows users to create very long exposures that would be impossible to achieve with a single exposure. This is particularly useful for astrophotography and landscape photography.
Star-Trail Images: Image Stacker can be used to create stunning star-trail images by combining multiple exposures of the same scene.
Digital Noise Reduction: Image Stacker can help reduce the appearance of digital noise in images by combining multiple exposures and selecting the best pixel values.

How to Use Image Stacker

Using Image Stacker is a straightforward process that involves the following steps:

Step 1: Download and Install Image Stacker

To use Image Stacker, you need to download and install the program from the official website. The program is available for Windows and can be run from the command-line and easily incorporated into scripts and batch files.
