Rob,
You may be surprised what you can do with digital photos. I also have a game cam and some of the pics don't turn out very well. But once you use a photo enhancement program on the pictures the bad ones can turn out pretty good. My suggestion is to save your original pics, make a copy and adjust on the copies with photo enhancement software. I would be willing to bet that you may see a lot more detail and be amazed with what you can bring out. I adjust on the "gamma" a good bit.
If you have problems, you can email me a pic and I can adjust on it to get the best results and email back. You can PM, (if you want).
