the quick answer to this is no you should not be able to photograph ghosts.
the longer one would take into account that if ghosts are from a paralel universe, or dimension, and that the dimension that they inhabit is in the spectrum, this spectrum is in the seeing range of animals such as cats and dogs. then yes under special circumstances you should be able to photo ghosts.
bearing in mind that I said if, and this theory may not be right.
What does it mean for a "dimension" to be "in the spectrum"?
I am not a scientist, but that sounds like it doesn't make any sense at all. A spectrum is a range of electromagnetic wavelengths. People talk of the visible spectrum (EM radiation visible to the human eye), the radio spectrum (relatively low frequency EM radiation), etc.
It doesn't mean anything for a "dimension" or "parallel universe" to be "in" a spectrum.
Can you clarify what you mean?
Anyway, the way I see it, if it can be seen, there is no theoretical reason (other than the usual made-up excuses) why anything visible to humans can't be captured on camera (digital or film or other) even if it's necessary to use film or a CCD device designed to capture EM radiation from outside the visible spectrum. Scientists and astronomers capture images from all over the EM spectrum from the extremes (gamma ray and radio wave images of galaxies and stars) to the more banal (visible light, infra-red and ultraviolet). If it emits EM radiation there is theoretically no reason why it can't be detected with the right equipment.
