There is no comparison in the usefulness and effectiveness of a digital trail camera with a film trail camera.

I would say I average 200 pictures a week on some of my cameras and sometimes I go a month or more between times I am able to check on them, I've had as many as 1,400 pictures on one camera when I went to retrieve the memory card. The largest roll of 35mm film I've seen is 36 exposures. I can't imagine the agony and expense of waiting for the film to get sent off and developed either!
