Are we talking about driving up someone's driveway and walking around their house taking photos? If it is obvious, yes, but sometimes, you can't tell what is private, like when you are dealing with large amounts of property that butt up to large state or local parks. I gave my experience earlier growing up and did not realize I wandered onto private property because I was just in a local municipal forest owned by the county. You could actually walk a few minutes and be in the state owned park, too, they looked exactly the same. This same area has a Presidential retreat, so many of my friends have wandered off trail while hiking , been lost, and ended up being meet by Secret Service, there are no visible markers anywhere in this particular area, for an obvious reason, they don't want the area to be found or marked out. Roads aren't even paved, but there are designated parking spots because it is a park. I guess I should be lucky I wandered into the farm with a camera and not the other direction...
Some of the civil war battlefields in our area are partially on private active working farms (because they were working farms back then too). There are no markers to let you know you walked off the battlefield area and onto a farm, unless you count the cow poo you stepped in. The farmers just tell visitors they wandered off path, because they deal with it, I am going to guess, nearly every day.
