On the subject of phantom photography (energy imprints or other), I haven't read Jane Tripps's book. However, if it may serve as an analogy, I've read some time ago (don't recall where) that for audio recording of paranormal voices, it is preferable to have a recording device that produces some "random" noise, with no active filtering. Whatever manifests does through the noise's "randomness", which similar to what Dean Radin's experiments show: mental phenomena influence the electro-photons in an light interference experiment. It is as if these phenomena would introduce some order/structure to a structureless (random) process. Then perhaps for photography, what is needed is low light/low signal to noise ratio photography with no active filtering or compression. Also, these phenomena may have ambiguity as an intrinsic property since they are anomalies. In other words, a photo of a ghostly apparition will always be ghostly, and a photo of a trans-dimensional being like a bigfoot will always be blurry will low quality.
