Or do a wedding, this requirement is lower, but wedding photography and video are also professional wedding companies. Going it alone is killing people, helping acquaintances and friends and trying to make money? Can't earn money back.
There is no need to think about the so-called "contribution". Newspapers and magazines have their own special photographers and regular contractors. The photos taken by an amateur are in the column of "Readers' Contributions" at most, and each photo is 30 yuan. What is enough?
Not to mention commercial galleries. Gallery has strict requirements on the size and resolution of photos. For example, many galleries require that the RAW size of digital photos before interpolation should be above 50M, and the full-frame SLR with more than 20 million pixels can barely meet the requirements. The seller of the gallery is either 120 film scanning, or Hasselblad, Freescale and so on. Can you take photos with an entry-level small SLR?
