Some pictures developed better than others. Temperature and duration of development are key, I think. Also, sun positioning, as I learned later on. Another thing I will note about developing Polaroid Land Camera pictures -- it's messy. You'll get the develoment chemicals on your hands. They're not dangerous, but bring a rag or paper towel to wipe you hands off. Also, I don't recommend stacking the pictures, even days after they've been taken. They have a tendency to stick together.
This first picture was taken by my son at the Piasa Bird painted on the bluffs of the Great River Road. I'll add that framing with a Land Camera can be a challenge. What you see in the viewfinder is definitely not necessarily what will appear in the photo.
