There are a number of items that you just can’t leave the house without.
A tripod is the most important piece of equipment you need, apart from your camera. Depending on which type of photography your interested in, it will become more critical. If I was doing landscape photography, I would definitely bring a tripod. To get the most in focus in your picture you need a smaller aperture, which will decrease the amount of light entering the lens. With a smaller amount of light entering the camera, the shutter speed will usually be increased to compensate for this, which means any movement on the photographers side will cause blurring in the photograph. Below I will recommend some tripods on different cost levels that I’ve used before.

Camera Cleaning Kit
It’s quite easy to explain why this is an essential thing to have in your bag. After time dust gets all over your lenses and in your camera. If this does happen it’s very important that you don’t touch the camera sensor with finger. I’m speaking from experience here, after I had to send one of my cameras to have a sensor replaced, this is something I never go anywhere without.
