I have seen thousands of trailcam pictures posted of deer taken by white flash cameras on trail cam forums. Most of these pictures were taken at mineral licks or feeder locations and the deer were not bothered at all by the flash. I am sure that you know that bucks become nocturnal very soon after the hunters take to the woods and the shooting starts. At this time of the year, anything new spooks deer, especially bucks. In five years of trailcamming, I have noticed that deer do not pay much attention to my cameras when they have been on location for awhile. They know the camera is there and they are accustomed to it. Most people that build homebrew cameras don't bother converting their cameras to IR flash any more because it has been proven that animals can see the IR flash. Humans can't see it but animals can. Around the time of hunting season, anythng new will spook deer. I have also made some other observations on this. When the camera is set up five to six feet in the air and aimed down watching a trail, the deer don't seem to even notice the flash. You can't hunt deer at night, so set the camera for day pictures only. If your camera is in the field long enough, the deer will get accumtomed to it. Leave it in your backyard for a couple of weeks, and your dog will not bothered by it after a few days.
