How to produce HDR images?
There are two main concepts to produce HDR images, the computer rendering process which help creating full High Dynamic Range images and using multiple shots of the image and merge those images into HDR image. The camera shots are known as Low Dynamic Range images as it does not provide that wide range of light and contrast. Thus, to be able to produce HDR images, multiple shots of the object with different settings are arranged together or laminated through applications such as Photoshop to produce the HDR images with high range of contrast and light that produces an artistic dramatic effect. Generally, the images that are used to produce the HDR images are taken as Camera RAW extension to provide the highest quality available to create the image depth.
