WebHere, the code scales mixed_tone to make it fit snugly into a 16-bit integer and then cast it to that data type using NumPy’s np.int16. Dividing mixed_tone by its maximum value scales it to between -1 and 1. When this signal is multiplied by 32767, it is scaled between -32767 and 32767, which is roughly the range of np.int16.

WebA curve filter is essentially a function, y = f (x), that maps an input pixel value x to an output pixel value y. The curve is parameterized by a set of n+1 anchor points, as follows: { (x_0,y_0), (x_1,y_1), ..., (x_n, y_n)}. Each anchor point is a pair of numbers that represent the input and output pixel values. WebJul 6, 2024 · To create an HDR image you will need: Take pictures with different exposures.
