@the_andrew is right, it's like telling someone to rebuild a car engine before they learn to drive. People love giving hardcore advice that sounds smart but just makes things harder.

Petrified wood needs a wet saw, not a tile saw.

Real learning happens in person, but my best cooking lesson was from a YouTube video.

Thick socks are a good start, but you have to get the right kind. A thin liner sock under a thick wool one cuts down on friction way more than just one bulky pair. It's the rubbing that causes blisters, not just pressure. That two layer system has saved me more times than I can count.

But what if the room is just too dark without it? My hands aren't that steady either. Would a longer exposure even work without a tripod? Seems like it would just end up blurry.
