This is a good way to gauge what quality of camera you will be buying. Larger, fancier cameras with high resolution images and interchangeable lenses—like a DSLR—can cost over $1,000 USD, while cheaper point-and-shoot cameras can be as little as $150 USD. A budget capped at $500 USD, for example, already excludes many cameras, and can help make your decision for you. The best camera for you will vary based on whether or not you'll use the camera daily, monthly, or only a couple of times annually. The more you use the camera, the more it makes sense to invest hundreds of dollars in it.  If all you need is a camera for vacation snapshots, then a cheaper model might be better for you. If you'll use the camera at least once a week (whether as a hobbyist or for professional purposes) consider a more expensive mirrorless camera or a DSLR. Or, if you'll use the camera frequently, but photo quality isn't a high priority, you could purchase a mid-range compact camera. A camera that's great for studio portraiture will not be a great camera to take on a hiking or backpacking trip. If you're planning on traveling with your camera or shooting outdoors, buy a camera that won't break the bank to replace. Likewise, if you're planning to shoot only high-quality indoor photos, opt for an expensive DSLR or mirrorless camera. As a general rule of thumb, smaller, more compact cameras and cameras with fewer removable or interchangeable parts are best for traveling with.
Decide how large of a budget you have for the camera. Consider how often you'll use the camera. Think about in what contexts you'll use the camera.
