If you trip is a once in a lifetime experience, then you may find that having just one digital camera or SLR will not be enough to record all the action.
Should your wallet be able to handle such spending, it is a possibility to consider purchasing a waterproof video camera as well. The only downside with such technology is batteries tend to drain quickly and may not be able to filter through dark patches of ocean on the film.
Top Tip: Never just have a video camera on its own because it can miss a lot of excellent photo opportunities that a digital camera or SLR may have picked up. This trip may only happen once so don’t waste any chances.
