My favorite camera accessory is my GorillaPod. A tripod is essential for capturing low light shots, and this particular one is small and light enough to stow in my backpack. However, the killer feature is the bendy legs which securely grip surfaces like light posts, trees and moving bikes, allowing you to get unique and special shots that might be inaccessible otherwise. For example, in this tricky shot, I’ve attached my camera and tripod to the railing on a canal.
It’s also great for getting group (or couple!) shots using the timing function, especially when there aren’t bystanders who can take your photo. Awwwwwww!
