Good quality film rolls are widely available but expensive. Please pay attention to the date of packaging and only buy from stores where the rolls are kept in a cool place. It is best to bring the films from home. Never leave a film or camera in a locked car. The mounting temperatures can badly affect the quality of the photographic material. Not all types of camera batteries are easy to find, so make sure you bring batteries that will last the entire trip or take a spare set. Cheap cameras are for sale in each city, but only in cities such as Quito, Cuenca and Guayaquil are there any quality cameras in stock, or a repair service. People are not always happy when you take a picture of them. When in doubt, ask for permission. Sometimes they will say no, or ask for money, which they clearly have a right to.
