Black & White Tool

The Black & White tool in Aperty allows you to convert your portrait into a monochrome image and offers precise control over how different colors are represented in grayscale. After converting to black and white, you can adjust how each color translates in brightness (luminance) or saturation to achieve the desired look for your portrait.

• Convert to B&W: This button automatically analyzes the image and converts it to black and white, removing all color information. The tonal values of the colors are now adjusted based on their luminance.

Luminance and Saturation Taps: These controls let you manipulate the brightness (luminance) or intensity (saturation) of different color ranges, even in a black-and-white image. Adjusting these sliders affects how light or dark each color translates in the final monochrome result:

• Red: Controls the brightness of areas originally containing red tones, such as lips or warm skin tones. Increasing the red luminance will make those areas lighter while decreasing it darkens them.

• Yellow: Adjusts the luminance of yellow tones, often affecting highlights in the skin. Raising this value brightens those areas while lowering it adds depth and contrast to the skin.

• Green: Primarily influences natural elements like foliage or clothing in the portrait. Increasing the luminance makes these elements appear lighter, while decreasing them adds more contrast and depth to green areas.

• Cyan: Adjusts the brightness of cyan tones, which can affect some clothing or background elements. A higher luminance lightens these areas, while a lower value darkens them.

• Blue: Impacts blue tones, often found in backgrounds or clothing. Increasing luminance brightens blues while decreasing it creates more dramatic contrast in these areas.

• Magenta: Controls magenta tones, typically affecting makeup or certain accessories. Brightening magenta lightens these elements while darkening creates a more dramatic effect.

After converting the portrait to black and white, use the luminance sliders to control how different areas of the image stand out. For example, increasing the luminance of red and yellow can brighten skin tones, while lowering blue or green can contrast background elements, creating a more striking portrait.
