They are, however, accessories that I would list as essential to a photographer's gear bag.
Just a little camera shake will cause blurring to some degree in the final photo. If you are landscape photographer you will really benefit from a polariser. There are many occasions when light conditions aren't good and the extra stability helps you create crisp, sharp images. A good solid tripod is essential to the kit of a photographer. One tip though is that you should always use one that has the equivalent or higher quality of your lens. Remember that these are my three top choices of accessories in no particular order. You need to choose which ones will serve your particular needs the best. 2. These aren't listed in any particular order and I don't think in any order of importance either although if you were to push me for an answer I would place a tripod as my number one accessory. Even when your camera is mounted on the tripod, the simplest action like pushing the shutter button can still cause camera shake and prevent you from taking the sharpest images. Happy shooting!
A good circular polarising filter
Buy the most expensive one you can afford. Those of you who have ever owned or used a pair of polaroid sunglasses will know the effect that it has on shiny and reflective surfaces. It works very simply either connected by a cable to the camera or using an infrared connection to activate the shutter.
The sky becomes bluer and the green vegetation greener. A tripod is especially useful when shooting close-ups of flowers and small creatures and helps you to have complete control of your images.
If you don't already have a tripod then get yourself one. Remote shutter release
I consider this essential. This is coupled with the tripod and is essential when avoiding camera shake. 1. So let's take a look at the three accessories I think that every photographer needs.
The digital part of photography is just the method of recording so what applies to photography applies to digital as well. I use all three equally but maybe if my photography changed slightly I would add another one or two to my list.
