Lesson Outline



Understanding the properties of a High Dynamic Range image
In this lesson we will explain the essential concepts and functionality of High Dynamic Range images




Capturing HDR images with your camera
In this lesson we will discuss the proper method for capturing images that are suitable for HDR assembly




Using a mirrored ball to capture your environment
In this lesson we will see how a simple mirrored ball can be used to capture your surrounding environment




Using a fisheye camera lens to capture your environment
In this lesson we will discuss how a fisheye lens can be used as a way to capture your surrounding environment




Constructing a multi-exposure HDR image in Photoshop
In this lesson we will learn how to assemble multiple LDR images into a single floating point HDR image




Building a multi-exposure HDR image in HDR Shop
In this lesson we will see how HDR shop can be used to assemble multiple images into a single HDR image




Unwrapping a mirrored ball image in HDR Shop
In this lesson we will use HDR shop to unwrap the mirrored ball HDR images
