Field pics are incredibly important, in my opinion.
Too many people take crappy ones or dont take them at all. While phones have made it easier, it's not easy to balance a phone by yourself and take a decent pic.
Some people just dont believe in it at all .... and I think that's just wrong. I know there will come a day when I no longer can hunt and when my memory starts to fade. The wall of 8x10s tells a story I will always look back on and reminisce
Mounts and racks on the wall are great, but looking at a mount you cant tell where he came from. You cant tell the time of day. You cant tell what the weather was like. A photo contains those important details. I remember most of them now, but I know there will be a time when that memory will start to fade.
I dont imagine it has ever taken me more than 10 minutes to balance my phone with a rock/stick and snap a few pictures.
Having said that, my biggest buck to date was an early season alpine buck that tumbled into an incredibly steep creek and I had no possible way to take a photo with him before he was cut up and packed out .... I regret it deeply.
