Best Practices

  • Start Big: larger image files (both in file size and in overal number of pixels) provide you with higher quality images. You can always scale the image down but you can't scale it up.
  • Keep your original: These images are typically your highest quality image and you may need to go back to them from time to time.
  • File naming is important: Come up with a naming convention that helps you quickly identify the image without having to open it. Names should include descriptive info, version, size, or intended use.
    • Example: Rainier_sunrise_1200_BW.psd - this file name identifies the subject of the photo, the image size (typically its width) and any processing that has been performed - this one is a black and white version, and its file format is a Photoshop document.
  • Save image(s) to the hard drive, to a pictures folder or the desktop, rather than working from a flashdrive, DVD or CD.
