I’m looking for some camera purchasing advice.

My little brother brought up that he’d like a camera to take pictures on an upcoming trip and to take it up as a hobby. Now, I know nothing about cameras/photography. My phone is sufficient for me.

Now, what camera would you recommend for a beginner? He’s been looking at the Canon Eos Rebel T6 (seems to be the go-to beginner’s DSLR). I’m trying to keep it under $500 if possible, it also doesn’t need to be that great at taking videos since he’s strictly interested in photography.
