Becoming a professional product photographer requires a combination of photography skills, a strong portfolio, and relevant experience or education. An associate or bachelor's degree in photography, graphic arts, or advertising is a great starting point. You can also build your portfolio while working as an assistant to an experienced photographer. It's important to have the right equipment for product photography, but the most important thing is to have a good understanding of light.
You can use speedlites to move from natural light to studio light, but they have their limitations. If you want more creative freedom and flexibility, product photography may not be the best option for you. When it comes to product photo backgrounds, the options are limitless if you don't need a seamless white background. You can experiment with different light sources and diffusion materials to create interesting effects.
To become a successful product photographer, you need to be willing to invest in the right equipment and take the time to learn about light and how it interacts with different surfaces. A good portfolio is essential for getting clients and building your reputation as a professional product photographer.
