Compact Digital Cameras

A point-and-shoot camera, also called a compact camera, is a camera designed primarily for simple operation. Most use auto focus for focusing, has automatic systems for setting exposure options, and usually have a flash unit built in.

Digital SLR Camera (DSLR)

With an SLR camera, you see exactly what the lens sees through the screen. You can change the lens on a digital SLR to suit your needs, if you want extra zoom or a different focal frame for example. Digital SLRs have large image sensors that produce high-quality photos, which may be very useful for professional photographers. A DSLR has a near-zero lag time, so it is ideal for action photography as well as still images. This means that Digital SLR cameras are versatile and suit whatever job needed.

Bridge Digital Cameras

A Bridge Camera is a digital cameras that has some degree of manual control. They have a long range zoom lens and a viewfinder – but they usually don't have interchangeable lenses. They are between a point and shoot camera, and a full DSLR. These are good for people that are stating out in photography and don't know how to manage all the features of the DSLR but want a step up from a point-and-shoot.

This means you could e-mail photos of your trip while you're still on holiday, or get pictures directly off your camera and send an editor quickly if you're a photojournalist.

- Downloading via USB: Alternatively to using wifi connection, most cameras come with a cable so they you are able to download photos you have taken on your camera onto your computer to save and then later send on, although this may cause cable tangle and clutter.

- Near-field communication (NFC): NFC (Near Field Communication) is an alternative type of wireless connectivity that uses electromagnetic radio fields to form its communication, rather than relying on radio waves. It enables a short-range communication between two devices, where one of them is usually mobile. A NFC connection is enabled when two devices are placed within 4 cm of each other. The data or images can then be transferred by a WiFi connection.

- HDMI: An HDMI cable can be used to connect your camera to your TV so you can view your images.

- Live stream: Some cameras let you video livestream whilst you're out and about, this livestream may just go to your mobile device nearby and save there or it may be online for many people to see. New 360 cameras have this function as it lets you relive the situations and make it enjoyable to watch in a 360 degree atmosphere.

Some digital cameras have more advanced editing functions. They may allow you to make colors in a photo more vivid, either overall or individually to blue, red or green. You can convert a digital photo to Black and White, Sepia Tone and a variety of other filters, add borders, add shadows or highlights, changing image quality etc.

Viewing

- Screen for viewing: Digital cameras give you the ability to look at a photo that you just shot to ensure that it looks right before you move on to another scene. If something is wrong in the picture, you can just re-shoot the image. The key to this feature is the display screen.

- Viewfinder: A viewfinder is what you can look through to compose, and, in many cases, focus the picture. A viewfinder lets the photographer see exactly what the lens sees and, therefore, gives better results.
