If required, the landscape pictures I like (If you do not have a built-in camera, electronic horizon level) circular polarization, besides the obvious, you can also spirit / bubble level is required. Anyway, so – I am no one, to save my life, I swear you can not get the horizon level.
You hot shoe (my Sony NEX-C3, etc.) If you own the camera without hot shoe is easy to find one, you can not cheap to get one mounted on a tripod. I’m in the part number joby.com get JB00124-CEN. Part number does not come up in the search, it “GorillaPod tripod, camera and accessories,” then appeared in the call for some reason “GorillaPod Hybrid / SLR-ZOOM Ball Head for additional bubble level clip.” It costs like $ 3 and $ 5 after delivery.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
