How Can I Get My Old Photos Onto My Computer?

Ah, the old photo albums! Or maybe it's more like the the old box-of-photos-that-really-should-go-in-an-album-someday. A significant number of households still have a a lot of printed photos and/or slides stored away. With he digital age, though, there's more and more pressure to digitize the photos as well so they can be saved on the computer and even go on the Internet if you so desire. This can seem like a daunting task though, especially if you don't know where to start...

The best place to start is with a rough approximation of how many photos you have that you want to put on your computer. This matters because while 50 photos might be easy enough to do yourself in an afternoon, 5,000 is a whole other ball game. If you fall into the later category and have thousands of photos, hiring a service that specializes in digitizing photos and videos might be worth it, but if you fall into the former, it might not. For this article, let's assume you've chosen to do it yourself.


An example of a digital negatives scanner.

How are you going to get the photos into the computer? With a scanner. If you only have a small number of photos and/or don't care about getting optimal quality, using a scanner that's built into a printer can work just fine; check your owner's manual for instructions on using the scanner.  If you have a large number, or do want the best possible quality, a stand alone photo scanner might be better for you. These can range in size, price and features so dramatically that it's difficult to give much guidance here except to look for "photo digital converters" and do lots of research before buying anything. What about slides and negatives you ask? Doing that same search will also yield results for devices that can scan those too!

Practical Tip of the Day:
Still not sure if it'd be cheaper to do it yourself or hire a company? Price out the cost of hiring someone, and compare it to the cost of any equipment you may need to buy + how much your time is worth. Whichever is cheaper is our answer! (Keep in mind that professionals will often get it done faster and have higher quality results though.)

What is VOIP?

As previously mentioned in the article entitled "What is Skype?" an increasing popular way to make long distance telephone calls, especially out of country, is using a VOIP service like Skype. VOIP stands for "voice over IP," which means that yes, it's an acronym that holds another acronym. "IP" means "Internet Protocol," so to break down "Voice Over Internet Protocol" it simply means that you can talk over the Internet like it's a phone.

To understand why this is impressive, one must first understand the difference between "analog" and "digital." If something is analog, it travels along a continuum. Think of this as the way someone can count between 1 and 2, using a seemingly infinite number of decimals between them. If something is digital, it's more like counting between 1 and 2 (well, 0 and 1 actually), but there are no decimals. It's either one or two. Sound is something that is analog, we can make a wide range of sounds, but computers and other electronic devices only understand digital (click here if you don't know why) so the trick is getting something to sound analog when in fact it's digital. I'll spare you the long explanation as to how that happens.

Once the sound is converted into a digital signal, it can then be sent over the Internet to anywhere you want it to go. When you use a service like Skype, you can "call" people to direct where your digitized voice will be sent to. The nice thing about the Internet is that whether your voice is going across town or across the world hardly changes the delay in conversation so it can simulate a phone very well, and since most countries have a decent connection to the Internet, it can usually also save you money versus using an actual telephone.

Practical Tip of the Day:
If you're travelling abroad, using a VOIP service can save you money versus calling long-distance, but be careful if you're using an "Internet anywhere" card or a smartphone to access the Internet for that purpose as roaming fees for data are often much heftier than roaming fees for voice, and a conversation over VOIP can use a significant amount of data. When travelling abroad, I usually recommend turning off data roaming and using Wifi only if possible to save you from surprise several hundred dollar phone bills when you return.
