To begin this tutorial it is assumed that you have a basic understanding of what HDR images are and their importance as well as a basic understanding of how to use Tone-Mapping Operators in Artizen. If not, please read What is HDR tutorial and Using Tone-Mapping Operators

Display Tone-Mapping Operator

Display is a global tone mapping operator that produces similar results that would be produced by the Display of a Digital Camera taking a single exposure. Display has been designed to reduce the contrast of the image using a complex global operation, which produces consistent results regardless of image size and is extremely fast. This makes fine tuning your results a very easy process.

Local Controls

Strength: This option adds local contrast functionality to the Display operator. Range (0 to 1)

Radius: This option controls the distribution of how the local contrast option is applied to the image, the high the value the more distributed the contrast is spread across an area. Range (0 to 1)

Exposure

Gamma - This option is the standard way of adjusting contrast in both displays and cameras but in a non linear method. Most Displays have a gamma level of 2.2, but since there are differences between gamma correction from device to device it is important to be able to adjust this option. Range (0 to 4)

Brightness: This option controls the overall brightness of the image and works similarly to a simple brightness color correction tool. Range (-10 to 10)

Contrast: Where Micro increases Micro Contrast, the Contrast option is a little more common to users as it can either reduce or increase Contrast across the entire image or what is commonly referred to as Global Contrast. Range (0.0 to 1.0)

Highlights: This option allows for fine tuning of only the Highlights in an image. This is usually one of the last options to be applied as it is one of the final adjustments to be made and can be used for fine tuning while watching the histogram. If you need to increase or reduce this value beyond +/-0.5 you should really consider bringing this value closer to zero and then increasing or decreasing the Luminosity value. Range (-1.0 to 1.0)

Shadows: This option like the Highlights is for fine tuning only the Shadows in an image. This option is also one of the last functions applied to the image and is therefore very easily used in conjunction with the Histogram. Range (-1.0 to 1.0)

Color Balance

Temperature - This option enables users to adjust the overall look of an image by changing the perceived temperature of a scene or correcting the white balance of your image. Usually blue is considered cool and red hot, but in nature the opposite is true. Range (-100 to 100)

Saturation - Controls the brightness of colors in a photo, with -1 being a black and white image, 0 being unchanged color level and 1 being colors boosted. Range (-1 to 1)

RGB Adjustments - Similar to the Temp and Hue options, these 3 options enable users to correct color shifts and white balance but on a individual color basis since color shifts don't always affect each color equally. Range (-100 to 100)
