That's a terrible route. You should be able to fly to Heathrow and then it's only 12 hours to Cape Town. We don't spend 36 hours in the air. Hawaii to Atlanta is 9 hours and then 18 hours on one flight to Joburg. The best time I've ever had is 34 hours door to door total travel time from Kona to Joburg but it's not fun. I've met people on the Atlanta flight that do it every month. They normally work for some charity or in Oil & Gas. With that many miles they get business or first so that makes it a lot easier but I'm sure it still takes its toll. I enjoyed looking at your work. I need to spend more time on the road.
When you really love photographing a certain subject, it shows in your work. If you've built a cohesive collection of images around a particular people or place, consider hanging it in a gallery or selling prints or photo books online. Share your work with artist's galleries in and around relevant locales until you find someone who bites. Southwestern USA photographer Brett Edge took it a step further and opened his own gorgeous fine art gallery in Moab, Utah. Photographer Vivienne Gucwa published a coffee table book featuring her New York City photography. Just getting started? Share your work online for exposure, and upload it to print-on-demand websites for effortless print sales.
Lyn's last tip is to have your own website. "Show off your work on Instagram and Facebook, but do ensure you have a good, easy to use website too. It should have some of your best work (with lots of keywords!), any specialities, and awards/competitions you have won, and your contact details. It's too easy to get carried away, add thousands of images, and forget the basics. Keep it simple."
