The long standing history of cats is without question. From before the Egyptians, cats have been a royal part of many peoples household. Some believe cats can protect a home from ghosts. No matter your stance on cats, they do poses a gift of incredible vision in very low light. But, how much more can they see?
Finally science agrees, they can see far more than previously suspected. This UV (ultra-violet) ability gives paranormal investigators hope. If cats are able to see spirits, then perhaps regular photography is possible one day.
Why isn't paranormal photography consistently possible now?
The answer is two-fold. One is that to date, a camera lens close to the ability of a human eye has not been invented. Therefore, to have a lens as advanced as the eye of a feline is a long way off. The second part of the answer is for those that can image the paranormal with great much better ability. Most people do not use their sixth sense when they are behind a camera. For those reading this that have conversations with spirits, you might understand easily. It is as simple as asking in your head for the spirits present to please show themselves. Yup, you simply ask them permission to take their picture. As with people, some spirits don't want to a picture taken. Others will be happy to oblige.
There are some basic guidelines to help obtain this very difficult exposure. The most important is to turn off your flash! I cannot stress this enough. Ghosts and spirits are in a whole different portion of the light spectrum. A flash of bright light will erase any apparition you see with your eyes, and that includes your camera. The next is the time of day. Now, the tricky part is the spirit may not be present at the best time of day. So, if the lighting is too low, use a tripod. You cannot extend the exposure time with spirit photography. You can add a small light source pointing away from the spirit. Next is the most difficult part for many people. Listen to your gut, to your instinct, and to your others senses. If you are not a medium/sensitive/physic, then you have to use what you have. Use all of your senses to see where to take your picture. Most pictures should be taken sooner rather than later. It takes a lot of energy for a spirit to manifest. So you likely only have one great chance early on. Feel the air temperature, use your EMF spikes, Geiger counter variations, and other tools available to you.
This isn't about proving or debunking. It's about working together to gather another piece of a very large and complicated puzzle. Remember, that if another person not present when you obtained your image "poo poo's" your picture, you know the truth. Yes, a sadly huge number of images are faked in this digital age. Creating a ghost is very easy. However, once you begin to take pictures of the real thing, you will be fast to learn how different each situation and spirit is.
Just like when the cats are staring and following "nothing" on the wall. They are curious as to what the spirit is doing. They are seeing movements we cannot do in our human bodies. And it's pretty darn interesting to see somebody play peek-a-boo through a wall. Or better yet, maybe they are looking at their long departed kitty spirit friend.
