Why images looks different after doing normalization

A.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])

is this how the images look like after normalization

The normalization creates a zero-mean and unit variance output and is thus expected. matplotlib will also clip the values as is mentioned in the usual warning you would get:

Clipping input data to the valid range for imshow with RGB data ([0..1] for floats or [0..255] for integers).
