Ⅲ. ADJUSTMENT
5. Lens Shading
A. Purpose
Lenses tend to make the edges of an image darker than the rest. This phenomenon is called "Lens Shading".
This adjustment will increase the brightness of the edges of an image by up to 80% of the centre of the image
by calculating the darkness levels at the edges in comparison with the centre.
B. Procedures
① Copy the adjust12.txt and adjust_t files onto the root directory of the SD card and install the card into the
camera.
