You can’t take a small, low-resolution photo and turn it into a poster. It just won’t work. It will pixilate and become blurry. So if you want to make a poster out of one of your favorite photos, start with a high resolution image. The higher the resolution of your photograph or digital file, the better your poster will turn out.
Many of today’s smartphones have fairly capable cameras, but we’ve found that customers often don’t take the time to set them up properly. One of the problems we come across in our work fairly frequently is low-resolution photos taken by these devices. Many cameras on phones are set up by default to take tiny little pictures for posting and viewing on the web. The problem is, web and print are two entirely different mediums. With print, the rule to follow is use the highest possible resolution. The higher the resolution, the more image detail you’ll get, which means the better your print will be especially if you plan to enlarge it.
Figure out what your device is capable of and then set it up correctly. Once you’ve snapped the photo it is too late to change things! Poke around in the settings for the camera on your phone and ensure that yours is set up to take pictures at the highest possible resolution. Doing so will allow you more flexibility in resizing your photos for printing.
Do you know what resolution the camera on your phone is set for? If not, and you plan to print your photos at some point, make sure you use the correct settings.
