ABSTRACT
Response curve Each time you load a set of bracketed images, Merge to HDR Pro automatically calculates a camera response curve based on the tonal range of images you are merging. As you merge more images from the same sensor, Merge to HDR Pro updates the response curve to improve its accuracy. If consistency is important when using Merge to HDR Pro to process files over a period of time, you might find it useful to save a custom response curve (see Step 3) and reuse the saved curve when merging images in the future.
