ACDSee works for me. Got a basic package for less than $100 in 2009 and customer service is great.
There are numerous editing programs available. But most of my photography friends use Photoshop. It was years ago, when I played with it. I thought it was just too dificult to learn. Here is a Photoshop photo from my friend Chris. He won a UN award for this shot. He is good. I ain't.
I recently bought the ACDSee Photo Professional 2018. It allows me to work with layers. Here is one example. Let's look at removing unwanted objects from a photo. Here is a Thai rice farmer spraying pesticides to his rice field.
