5. Camera settings
I've spoken about the importance of shooting in raw in the past, but I could apply it even more when you're traveling and shooting on the fly. When you're traveling, you often don't have the chance to take the same photo twice. Shooting raw could save a photo that was accidentally over or underexposed. If you find it too time consuming to shoot in manual mode, you can also shoot with shutter or aperture priority.
6. Keep your files organised
As tired as I am when I get back from a day of adventuring and exploring, before I go to sleep I like to download all the photos I took that day in a folder named with the date and the location we went to and put my camera batteries on charge. It can be difficult to stay on top of this, the longer you travel, the more tired you are. But trust me you will be thanking yourself when you get home if you can roughly stick to this schedule! Instead of coming home to a giant pile of mixed up photos, you already have everything sorted by date and name which will make going through all your photos when you're home so much easier!
Another thing to keep in mind if you're downloading photos on the road and re-shooting on cards is backing up your files. I know they're not client photos, but your holiday photos are just as important in my opinion! If you can purchase a small, cheap hard drive somewhere at home to take with you, back up your photos whenever you have some extra downtime at your hotel or apartment.
7. Take candid photos
While it's great to have posed photos in front of landmarks, don't forget to get candid photos too! I love candid photos as they remind me more of the atmosphere of the day rather than just showing me where I was. So snap away at your friends walking around, take pictures of interesting characters you see on the streets and keep it natural!
