Cameras are designed only for right-handed people
Most right-handed people would barely notice how left-handed people use cameras. If you have paid close attention to the body of a camera, you will notice that strangely enough, the shutter-release button is placed on the right panel of a camera. There have been some exceptions as a few companies have manufactured cameras that have important buttons situated on the left panel. But, these customised cameras have been made for famous photographers and have not been produced on a large scale. Therefore, most left-handed people face a lot of problems while trying to deal with cameras originally made for right-handed people.
