If you are going on a trip for a few weeks to work on your photography, there is one very simple heuristic you should live by:
- Bring one camera, and one lens.
Having a secondary body and lens is a good idea, but for the most part, you want to be locked in. Switching between different camera setups, lenses, gear etc. is going to be a huge distraction. If you are looking to come home with the best results possible, just glue on the lens to a single body, and go as hard as you can each day.
Also, don’t try to juggle a million different ideas or types of photos you want to make. If you are going to practice street photography, focus on making street photos. Don’t worry about portraits, landscapes, etc. You need to be laser focused on your vision if you want to come home with anything good.
