In order to get this sunrise photo, I needed to abuse my tripod a bit. I spread the legs wide and low to get the angle I wanted. I also wanted to get the water from the retreating waves in the photo. This meant that the surf was washing up over my tripod legs. Sand and saltwater was everywhere inside and out of my tripod legs.
So, when I got home, I needed to disassemble each leg and clean it inside and out. This is why you need to spend more money than you want for a really good tripod. It needs to be made of good quality materials. It also needs to have the ability to be taken apart and put back together. I have been using and abusing this tripod for nearly 30 years. It still works like it did when it was new.
