File formats: Most point-and-shoots save pictures as JPEGs, a commonly used file format. A few use Raw, a format that’s ideal for users who want to do significant image editing on their pictures.

Memory cards: Cameras require a memory card, usually a Secure Digital (SD card). Cards that are bundled with cameras have a small capacity, so you might want to buy a card with a larger capacity.
Software bundles: Almost all point-and-shoot cameras work with Apple’s iPhoto software for importing pictures from the camera. You can also access the memory card using a card reader, and use the card like you would any other storage device.
All cameras come with software, but the included Mac software is often outdated. You’re better off using to manage your pictures and to make minor adjustments.
