When traveling it is not as easy as with a conventional camera with a roll or two of film. A digital camera has a fixed storage capacity and we can only add to it by buying expensive flash memory cards. To compensate for this, it therefore makes sense to carry a notebook computer - if we have one -- and transfer the pictures to it periodically to free the badly needed camera memory.
We can also preview the pictures and decide if we want to want to erase them, e-mail them, or post them on the web. If our notebook computer has a CD writer then we can transfer the images to a CD. We can even carry a small printer and print the images, or have them printed at a shop that provides this service. If we do not want to carry a notebook, the images can be transferred directly to a portable hard drive. This battery-powered, palm-sized device may come with or without a monitor. Or we can also transfer pictures to a Clik! drive, which is a portable storage device, powered by a rechargeable battery.
Once the images have been transferred to the Clik! drive, we can free up space on our flash memory card by erasing the images. When a Clik! disc gets filled we can replace it with another one, which may cost $10. Once we return from the trip, we can transfer the images to our computer. If a person is planning on a lot of traveling with a digital camera, this would be the way to go. Electricity and power are not the same in different areas of the world and there will be many ways to compensate for it. In the US, the power supply is 110 volts and 60 Hz, whereas when you travel overseas, the voltage may be 220 volts and 50 Hz.
The wall outlets may also be different. We will need an adapter kit, to plug in our notebook computer, AC adapter, or battery charger. A transformer is suitable for use with electronic devices.
A converter can be used with electrical appliances like hair driers. It can harm devices over time and should not be used for more than a few hours. Transformers can be used for longer periods, though they tend to be heavier. When traveling, if a modem will be needed we would need to find out about the type of adapters that are used in the country where we are going. While hiking, canoeing, or sailing, we will need a solar-powered battery charger, to recharge our batteries.
The digital camera, laptop computer, flash cards, audio and video tapes, floppy discs and films will remain unharmed by the X-ray machines installed at airports. However, a metal detector may harm magnetic media like Clik! Discs. Please keep this in mind while traveling by air and be prepared.
