Can digital photos contain more than one type of noise?

Question

I am aware of the different noise models usually found in digital photography such as Uniform, Gaussian, Laplace, Lorentz, Poisson, etc. But do photographs usually contain various types of noises combined or just one? I've read noise removal software depends on reading the image's histogram to find out the noise distribution and thereby identify which type of noise is in an image but this suggests there is always only one type of noise inherent? I can't seem to find any information on this. Any info is appreciated.

Answer 1

It is better to separate a noise that is produced by a sensor in a DSLR camera from mathematical noise models that are used to describe it. Yes, a photograph may contain three main types of noise: Banding (vertical lines), Fixed Pattern (pixels that get 'hot' during long exposures) and Random. Whereas you are listing different models that are used to describe digital signal noise. A sensor is not programmed to produce a noise based on a noise model.
