For more dynamic range, one can create a. This should be plenty of dynamic range already. I am using images captured using a Nikon Z6 (which has a dynamic range of about 14 EVs) and exposed “to the right” (or close) in order to preserve highlights.

In order to produce and view an HDR image, we need the following things:Īn input file capable of representing a scene with a high dynamic range. I found it a bit glitchy, but it otherwise worked. An open-source viewer for EXR files, that supports 10-bit HDR, is tev. ²This should probably work too with any recent HDR-capable laptop and a compatible viewer. Since I was getting a mac to replace my old, dying laptop, I decided to give it a try.² I do not print much, therefore a monitor (or a projector) is a perfectly reasonable output medium for me, and I don’t need to limit my edits to the limited dynamic range of paper.Ī few months ago, I came across this post by on PlayRaw, where he showed that the built-in Preview app in macOS was able to trigger the HDR mode when opening. The device left quite an impression on me, and since then I have been wondering how I could leverage this technology for displaying photos. I got interested in this topic after viewing some HDR videos on the mini-LED iPad Pro last year. This is not very surprising since the human eye can perceive a much wider range of luminance and colors than what a SDR display can reproduce. I await your suggestions!Īs we will see, this can lead to images that look much more natural and pleasing to the eye than the “SDR” images to which we are used to.

¹Yes, we need a better (and more easily searchable) name for that, that distinguishes itself from what is usually referred to as “HDR photography” i.e. producing files which, when viewed with a compatible viewer and a compatible display, produce an image with a potentially much higher contrast (and larger gamut volume) than what is achievable with a SDR display or a SDR format like JPEG. Lately, I have been experimenting with “display HDR” photography¹, i.e.
