This box talks about the color tools proposed in the photo editor software MS Photos

• Light

Brightness, Exposure, Contrast, Highlights, shadows, vignette

• Color

Saturation, warmth, Tint

The mosaic shows effects of the tools from minimum (left), to maximum (right) of the different parameters that a user can tune in MS Photos, with the original picture in the middle.

Left to right, top to bottom, effects of: Brightness, Exposure, Contrast, Highlights, shadows, vignette, saturation, warmth, Tint

These ready to tune effects modulate values of the coordinates in the color spaces Red, Green, Blue, Hue, Saturation, Light or Brightness, to change the color attributes of the pixels (the size of the picture is 628px x 635px).

16. Rearranging colors, less or more colors, grouping

⇨ [Map tool -rearrange colormap, set colormap, alien map, color exchange, rotate colors, gradient map, palette map, sample colorize-]

⇨ [Tone mapping -Fattal et al. 2002, Mantiuk 2006, Reinhard 2005, Stress, Retinex-];

17. Getting information and characterizing images with math parameters

⇨ [Info tool -Histogram, Border Average, colorcube analysis, smooth palette];

18. Coloring to two colors

 ⇨ [Threshold tool]

19. Grayscaling and monochromatic coloring
