This is basically a question for community members (photographers). Are there any general promotional steps that shown as a successful when speaking about selling the photos. How do you get your customers? Do you pay for adverts? Do you know any good place for advertising?
Are social medias good enough?

I'll add a few comments here since I am a photographer as well as being a Fotomoto employee =)
Most successful photographers that I've spoken with market their services in a number of ways. Depending on your specialty, trade industry publications can be an effective marketing tool, especially for wedding photographers and the like. Website marketing and good SEO can be very helpful so that people searching for your service can find you and learn about what makes you unique from other photographers in your market. Word of mouth is another important factor, as is focusing on the needs of your existing customers.
Last, since I do work at Fotomoto, make sure you check our the sharing tools that we offer.
I hope that helps, and looking forward to hearing more here from others in the Community.
