Can digital photos contain more than one type of noise?

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.
