Image resolution - why should you care?

Do you know those TV shows about cops or spies where they take horribly out of focus or pixelated images and make them so clear that they can identify the bad guy? Totally fake, doesn't exist. If it does exist - someone please tell me how!

Image resolution in the digital world refers to the amount of detail or information contained in your image file. Higher resolution = more detail = better quality (and larger file size). That is a pretty basic and simple explanation for more visit this wiki article.

Here are some tips that may help you along your way:
  1. You can always reduce the size of the image without sacrificing the quality.
  2. You can never enlarge the size of the image without sacrificing the quality.
  3. For photos, set your camera to the Large or highest setting to get the best quality prints.
  4. If your graphic designer is providing you with a .jpg file of your logo make sure it is large or have them give you several sizes.
  5. If you want to print your images you need at least 300 dpi (dots per inch) at the size you want it to print. This includes photos, print ads, logos, etc.
  6. For web images 72 dpi is fine and all images should be optimized for the web so that they load quickly.
Good luck!

  1. Fantastic suggestions! As a photographer I can totally relate to this. What also bugs me is the myth that you can correct an out of focus shot in post. No you can not. I bought into that until I actually switched to a DSLR and learned how wrong I was - ha ha
