Figure 3

9 images acquired with light of colour temperature 12; 8,5 and 5 V and following 12; 8,5 and 5 WB camera settings shown: in chromatic space: a - horizontal and b - vertical axis. The 3 images acquired with lower WB setting than light temperature are marked with dark blue colour, 3 images with higher WB setting with yellow colour and 3 images with balanced WB with red colour. Images acquired with adjusted light and camera settings are located in the region marked by the red circle. The arrows connect the original and corrected image. Colour and WB manipulations causes images' colours standardization, that can be observed as orange and light blue point move closer to the (0,0) point.
