In contrast with most of my peers, I seldom use Photoshop and have never used Lightroom. However, I rely on three post-processing/editing apps as my tools of choice...these are Color Efex Pro (originally of Google and now part of DxO Software, Iridient Developer (the raw image format processing software for macOS, and well known for its ability to process Fujifilm X-Trans raw files), and lastly ON1 Photo Raw ( a raw processor, photo editor and plug-in collection all in one).
As an approved photographer on stock libraries, you can possibly get access to client briefs where you can submit your work direct to the client, meaning they’ll consider you for the project and see your profile. Otherwise there’s usually a marketplace type system for you to upload your images and have them added to collections based on themes, destinations and seasons.
After spending the last 6 years fiddling and learning photography, my wife and I are about to move to Cambridge, UK from Melbourne. We are planning to post and write about our European trips in a capacity that is more than just telling our family what we are doing with the goal of allowing our work to eventually pay for our travel. Our first real post will be up soon, looking at our short weekend trip into the Wimmera/Mallee to visit the new Silo Art in the region. My Wife is a much better writer than I am and is currently editing!
