Dave Skinner, pro-staff for Spartan Camera and Go Cam, offers some great tips for setting and positioning your cameras:
I like to position my cameras approximately waist high, or about eye level for deer, for the best photo quality and the best angle for judging their age, and antler score.
For the absolute best photo quality, you want to set the camera 15’ or so from the target, about waist high pointing north or south so the camera is not looking directly into the rising or setting sun.
A nice wall of vegetation behind the target will reflect the infrared flash and result in better quality photos.
If it’s a trail set, angle the camera up or down the trail for a better centered image rather than putting the camera on the edge of the trail looking directly across it. Better yet, attempt to locate the camera at a spot where 2 trails intersect, increasing your odds of photographing bucks.
Great tips there, I’ll try them out.
