For Deer. I believe they both can be seen by the animals, ie deer. I also believe that animals get used to seeing these "flashes" from both cams. I've had many great pix from IR and from White Flash cameras at night, some spooking and some not. In my experience though, (oh boy here we go) it seems when ever I have a nice buck get "caught" from the White Flash Camera, I won't see that buck again for awhile, or ever again. Coincidence??? I dunno. Could have been, but not so much for the IR cam. Many bucks, same bucks, over and over bucks......(may be one camera smelled funny....

)
Now in saying that I know deer change their patterns throughout the year because of food, hormones, and pressure etc.. So I can't base my answer soley on the pic's.... though I do. I will use my IR in an area that I am trying to catch a certain Buck....during hunting season, and use the White Flash any other times, Especially for turkey. So I'm voting IR.......even though I own both....

Oh yeah, I won't use the White Flash ANYWHERE near public land or close to a road and what not..... lots of honest people out there, and some not so much. We were coon hunting some public land and the dogs had a coon tree'd and about every minute this white flash would appear in the woods (middle of the winter) and could be seen for ever. Needless to say, we gathered the dogs up and got a few more poses of us and the dogs b4 we left!!! Priceless, I just wonder if the guy is on this site........hmmm
