This is a question that has plagued many people. I have people ask me from time-to-time, what does DPI mean. DPI is an acronym for “Dot Per Inch”. In simplistic terms, DPI is really just a way of conveying the measurement for output to a medium, such as paper.
If you have digital images that you want to print out, you can use the full size version of the image that comes right from your digital camera. You shouldn’t have any problems with printing out your images this way.
One of the most common problems I see occur, is when people are trying to print out their digital images and they have reduced the size of their digital images for emailing or other purposes. When reducing the size of the image, the resolution and DPIs of the image will also be changed. This can cause you to have some issues with printing. Make sure you always keep the original image around and make changes to a copy of the original image for emailing to friends, posting on facebook, etc. When you go to print out some of your digital images, you’ll be glad you kept the originals. I have learned this lesson the hard way, like so many others.
