I spotted this one while walking my dog around my in-laws’ property. A 50-ish gallon tank was buried in the weeds behind a barn. I think it was used for farm diesel and this is the fill hole. Whatever it is, I really liked the texture so I pulled out my iPhone for a couple quick shots. I used the native HDR setting to enhance the shadow detail and processed with the Snapseed app. This is quickly becoming my photo-editing favorite.
