Three-way tripod heads allow you to adjust the angle of each axis separately. They are therefore suitable for making precise compositions, making them ideal for "slower" types of photography such as landscape, architecture, product photos and panoramas.
Not always. Most tripod models come with a head, especially those designed for beginners; professional tripods, on the other hand, often leave the choice of head to the photographer.
Three-way tripod heads are the most versatile option. They are slightly cheaper and more suitable for "slower" types of photography, where you have plenty of time to set up the composition. Ball heads are more suitable for "faster" types of photography that require rapid readjustments, such as sports or wildlife photography.
A tripod is essential piece of photographic kit used to stabilise the camera during longer exposure times.
The tripod head attaches the supported device (e.g. a camera) to the tripod legs and allows the device to be locked or positioned in different ways. Tripod heads differ according to the clamping mechanism used and the method of adjusting the axis.
Image stabilisation helps to prevent blur caused by camera shake. You should consider getting a lens with image stabilisation if you often use zoom or shoot without a tripod.
