The original image is taken in Italy with our friends' son Lucas coming down the slide.
The curve described in the course notes is applied givind a representation of what an image that has not had a gamma correction curve applied. This image, as seen below, is darker. The applied curve is shown at the side.
A curve was thereafter applied to bring the altered image, without the gamma correction curve, back to its original state.
Looking at the image which has been converted back, as near as possible, to the origina, is more noisy.
