So, **image2** is the subtraction of **image** and **Scalar::all(i)**. In fact, what happens
here is that every pixel of **image2** will be the result of subtracting every pixel of
**image** minus the value of **i** (remember that for each pixel we are considering three values
such as R, G and B, so each of them will be affected)
Also remember that the substraction operation *always* performs internally a **saturate**
Also remember that the subtraction operation *always* performs internally a **saturate**
operation, which means that the result obtained will always be inside the allowed range (no
negative and between 0 and 255 for our example).
