You need to learn how to resize pictures.
You want to share your digital photos with your friends and family.
It's good to know the best picture sizes for printing, emailing and sharing on the web.
Whether you are printing at home using your own printer or sending them off to your local drug store, department store or national online printing company such as Snapfish or Shutterfly, you will get better digital photo prints by learning a few things about resizing photos.
Your ink jet printer in your home or office actually prints tiny colored dots on a page. Resolution in printing is measured by "dots per inch" or DPI.The dots are so small and there are so many that your eyes perceive them as continuous colors.
If you try to print a 72 PPI picture on a 300 DPI printer, it won't usually look as good as it does on the computer monitor. The printer doesn't have enough dots of information to create a clear, sharp image.
Most digital camera have large sensors and give you big picture files. Sometimes those big files will slow up your computer or be too big for many email programs to handle. If you make picture smaller, like to a 5x7 inch size at 72 PPI, it is big enough to view on your computer and small enough to send by email.
Sharing on the web
Viewing photos online does not require a large photo size. Computer monitors resolution and photos on your computer are measured in "pixels per inch" or PPI.
Pictures on the Web are usually 96 or 72 PPI because that is the resolution of most computer monitors. Higher Resolution is a waste of memory.
I use "Image Size" in Photoshop because it gives me complete control over the dimensions, the resolution and overall size of an image. You can also vary the quality setting when you save an image to compress the data more without losing pixels.
Have a blast with your digital photography!
