Orbs and digital cameras
Let me start off saying that I love my digital camera. I have a Kodak Easy Share DX3700 3.1 mega pixel. It has enabled me to ghost hunt without spending major $$ on film and processing.
Technology is growing my leaps and bounds and now digital cameras are better then ever.
There has been some controversy regarding digital camera use in ghost investigations. The founder of American Ghost Hunters Society Troy Taylor - has his own theory on digital camera use. Instead of going into it, I'll let you read it for yourself here Troy on digital cameras.
The IGHS has a different view entirely and you can read it here IGHS views on digitals.
I personally am somewhat in the middle. I don't trust the very low quality cameras with the low pixel resolution. I feel there very well could be some interference from natural sources, like dust of lens flares. But you can also get these interference on film. Now with the clear pictures of the higher end models and even night shot capabilities, the sky is the limit.
I'll let you decide for yourself
