HDR Photography Workflow: Part 2 of 3 / SML Tutorial
Part 2 of 3
By keeping everything in 16-bit color space we can manipulate the image further once we have all our materials together.
Most strange looking HDR images found on the web is a result of people exporting to JPEGs after this. But this image was not what I had in mind when I looked at the landscape, so let’s work on this further.
To further reveal details in the shadow, I created a curve which targets only the shadow area. Shown here in the layer blending options you can see that I have targeted the curve adjustment to only affect a graduated area. If I do not do this, the sunlight would have been over-exposed again.
Also note that I am using the Lab color mode inside Photoshop. This allows me to work with the luminance, or lightness, separated from the color a/b channels.
After I am satisfied with the shadow overall contrast, I work with the overall luminance contrast for the overall image. Obviously the curve shown here is specific to this image.
Now I created a layer mask with a basic gradient fill so I can use the curve to adjust the tonal contrast for the sky.
