“You can find numerous free online courses and YouTube videos to help you develop this skill,” said Kevin Mercier, an entrepreneur and professional photographer at kevmrc.com. “You can use these courses to learn about light, exposure, color, tone, and timing. This will help you produce more creative, interesting, and noticeable photographs. You can sell almost any photo online, from street photography to pictures of food and animals.
Mercier recommends trying Alamy first to begin selling your stock photos. On average, photos on Alamy sell for around $75 each but could get anywhere from $17-$416, depending on what they are used for.
According to Indeed, the average hourly rate for photography is $20.12, but how much you earn will depend on how you monetize yourself. You can increase your income by focusing on specialty events like weddings and conferences.
