I am very excited for you that you are taking a trip solo! And pictures are really important! Even if you don't like your photo taken, it's really nice to have a few pictures just to remind yourself of the trip and to share with your friends and family. We all appreciate a good view but when you are in it, it's more personal and truly yours. You might have wondered how can solo travel instagrammers take pictures of themselves. It's actually not too hard! The photo below was taken by myself in Sri Lanka.
Here are the four tricks I regularly use!
1- Mini Tripod and Timer
I use the Joby tripods because they are so versatile and can be twisted and places in random spots. I think most cameras would have a timer. Look into how to set that before you trip! You don't want to be fiddling with your camera and figuring that out on the spot. 10 seconds is the most common time, but you can set the duration. Possibly 20 seconds so you don't have to run to the spot.
Ps1. You can do that on your phone too!
Ps2. You can take a proper tripod with you if you like but that might be too heavy to carry.
