I don’t always like to carry around my photography gear. My bag with all my equipment in it is usually 25lbs and sometimes it just becomes a nuisance. Carrying around that equipment just isn’t always practical, or necessary, but I do always have my cell phone.
Modern cell phones have great cameras now. Don’t expect to be able to enlarge the photos to billboard size but for everyday use or for social media, a cell phone camera is often all you need. They have some great features that a DSLR would have, like the ability to change your ISO or your shutter speed.
