Start with the portfolio. A website and social accounts can help people find you, but they won’t matter if the work itself isn’t consistently excellent and distinctive. Build a strong portfolio, improve it continually, and make sure potential buyers can see it.

From there, think like a business owner. Professional photography is not just taking good pictures: you need clients who will either pay to license your images or hire you to shoot. That means marketing, sales, customer service, bookkeeping, taxes, and the other realities of running a small business.

The key point is that great photos are necessary, but not sufficient. Many people can make strong images; the hard part is finding and serving paying customers.

Also go in with realistic expectations: landscape/nature photography is a very competitive field, so relying only on website sales is risky. For many people, it makes more sense to keep developing their work first and treat it as a hobby unless they’re fully committed to the business side as well.
