Final Render Window - Image Processing Tab

The image processing tab allows you to make detailed, non-destructive photographic adjustments to the rendered image.

You can choose Basic or Advanced Image Processing.

Basic Image Processing

Advanced Image Processing Toggles between Advanced and Basic Image Processing options.
Image Processing Applies Image Processing settings to the rendered image.
Bloom Turns on bloom. Bloom occurs when a very bright part of an image neighbors a very dark part, causing the bright part to appear to glow. You can turn on and adjust bloom from the PhotoView Options PropertyManager, and further adjust it in the Final Render window. Bloom is not visible in the Preview window. The following options are also available:

Bloom Setpoint

Identifies level of brightness or emissiveness to which bloom effect is applied. Decreasing the percentage applies the effect to more items. Increasing it applies the effect to fewer items.

Bloom Extent

Sets the distance the bloom radiates from source.

Input White Level Sets the threshold for what is considered white in the image. By default, pixels with a value of 1.0 or higher are considered white. Lowering the input white level allows pixels with lower values to be considered white, increasing the overall luminance of the image.
Saturation Controls the amount of color in an image, independent of luminance. At 100%, colors are fully saturated. Reducing the value reduces the overall color saturation. At 0%, the image displays only gray shades. You can also increase saturation above 100% without introducing the color banding and artifacts generally associated with oversaturating images.

Input Levels and Offsets

Monitors You can use several types of feedback displays to analyze values in an impartial way when making adjustments:

Waveform

Displays the amount of energy at each intensity level as a series of vertical strips. You can use Waveform to detect crushed shadows or blown out highlights or to check how evenly the overall tonal range is used in the image.

Vectorscope

Displays the amount of energy across the hue and saturation spectrum as a unit circle of colors. You can use Vectorscope to check the overall color balance or examine the amount of saturation for a specific color range.

Hue and Saturation Parade

Displays the amount of energy in hue or saturation as a series of vertical strips.
Levels Channel Specifies which channel information is displayed by the monitor: Colors, Luminosity, Red, Green, or Blue.
Display Intensity Controls the display intensity of the monitors to allow you to view intensity levels for under-sampled areas of the image.
Display Range Controls the range of the monitors. The default range is 0 to 1.
Level Offset Slides all color values up or down the value scale, shifting them identical amounts in the rendered image. For example, if an image had a 0% black pixel and a 50% gray pixel, offsetting the values 50% would result in the black pixel changing to 50% gray and the gray pixel changing to 100% white with all other values changing corresponding amounts.
Input Black Level Sets the threshold for what is considered black in the image. By default, pixels with a value of 0.0 W/srm2 are black. Increasing the Input Black Level allows pixels with a value higher than 0.0 to be considered black, darkening the overall image.
Input Gray Level A non-linear luminance adjustment that applies a curve-like function to the pixels, modifying the midrange the most while decreasing the adjustment amount for values closer to the defined black and white points. Values above 1 lighten the midrange, while values below 1 darken the midrange.
Input White Level Sets the threshold for what is considered white in the image. By default, pixels with a luminance value of 1.0 W/srm2 or higher are considered white. Decreasing the Input White Level allows pixels with lower values to be considered white, increasing the overall luminance of the image. Increasing the Input White Level requires pixels to have a higher luminance value to be considered white, decreasing the overall luminance of the image.
Tone Mapping Allows you to compress the dynamic range of the image.

PhotoView 360 captures the full range of lights and darks in an image (dynamic range). However, your monitor cannot display the full dynamic range, so details may be obscured in very bright or very dark areas, causing the image to look over or underexposed. When you use Tone Mapping to compress the dynamic range, the details in the darkest and brightest parts of the image become visible.

It often takes a combination of White Level, Tone Mapping, and Output Gamma settings to achieve the best result.
Hue Offset Adjusts the color values of the rendered image independent of the luminosity values, shifting them across the entire spectrum in a sequential fashion. For example red color values shift toward an orange hue, then yellow and so on. You can think of hue values like a wheel, where a rotation of 180° inverts all the color values and a rotation of 0° brings them back to their initial state.

Color Push and Pull

Colorization Adds a color tint to the image. You can add a tint for artistic reasons or to reverse an accidental color cast caused by scene lighting or other issues. A value of 0% produces no colorization, whereas at 100%, the target color completely replaces the image.
Target Color Sets the color used for colorization.
Saturation Controls the amount of color in an image, independent of luminance. At 100%, colors are fully saturated. Reducing the value reduces the overall color saturation. At 0%, the image displays only gray shades. You can also increase saturation above 100% without introducing the color banding and artifacts generally associated with oversaturating images.

Output Levels

Monitor

Histogram

Shows the distribution and levels of the spectrum of colors in the image. You can use this to determine if an image is neutral, low key, or high contrast.

RGB Parade

Shows individual Red, Green, and Blue channels side by side, providing a clearer view of each channel's contribution to the final image.
Channel Specifies which channel information is displayed by the monitor: Colors, Luminosity, Red, Green, or Blue.
Display Minimum/Maximum Sets the range of the monitor to values other than the default 0 to 1 range.
Output Black Level Adjusts the overall tonal range of the image. Increasing the value allows previously dark areas to display in color.
Output White Level Determines the output value of what is considered fully white in the image. Increasing the value allows more pixels to be considered white. As this value changes, intermediate values between black and white change as well.
Output Gamma Adjusts the midtones of the rendered image while preserving the extreme whites and blacks. Increasing the value lightens the midtones. Decreasing the value darkens the midtones. You can also adjust the gamma in the PhotoView 360 Options PropertyManager.
