Composition, lighting, and use of colors: these are some of the major fundamentals that actually matter in photography. I'm assuming that many of you already know what's going to happen when a professional photographer swaps his equipment with an amateur.
We've all probably seen videos where a professional photographer shoots with a cheaper system than they're used to and still manages to produce stunning results. The main reason for this is because experience and skill are what truly separate a good photographer from a bad one. There's no camera that I can think of that will automatically produce an incredibly well-composed image. Or know precisely how to light a subject. These skills tend to take time and lots of practice. Even still, I always find it interesting to see videos where a professional and amateur photographer swap their gear for a shootout. In a recent video from a channel called Henbu, they do precisely this. The equipment used in the comparison is the Sony a7 III with a number of lenses including the Tamron 28-75mm f/2.8 versus the Sony a6000 with the kit lens. In my view, I thought both photographers produced some great results. This goes to show how little the equipment was really impacting the overall performance.
Of course, there are benefits to shooting with better, more capable equipment, but the most important aspects of what make a good image can't really be found in a sharper lens or a camera with more dynamic range.
