Hi Guys, I hope you can help with this. My dog, a two year old black lab, has been lame since April. He's been to the vet, had examinations, X-rays, CT scans, the works and yet the cause / source of his problem remains undiagnosed. Could be his wrist, elbow, shoulder or even triceps muscle. I had a brainwave: have a look at him with an IR camera to check for hot spots. So I borrowed a night vision scope, waited for dark and had a look. I could clearly see a green tinted version of Harry with some brighter highlights but I don't think the bright spots represent heat; I think they are just shiny bits that reflect more IR. This brings me back to cameras and filters. I've looked at the IR threads here but they are, while very interesting and unusual, mostly of trees and landscapes. I want an IR image that shows up a heat signature. Can that be done based on my EP 1 or EPL5 or even if it involves buying an older DSLR? And if so can anyone here give me the step by step instructions I'd need? Many thanks in anticipation from both me and Harry.
