Final answer:
Adjust the photo size for screen display to 72dpi or to a higher resolution for printing, ensuring best quality with no compression and using tools to compress later if needed. Make sure the subject fills the frame and apply the rule of thirds for a balanced composition.
Step-by-step explanation:
Once you are satisfied with your image placement, you should adjust the size of the photo for optimal web viewing before returning to the main editing section. If the image is intended primarily for screen display, a resolution of 72dpi (dots per inch) is typically sufficient. For printing, a higher resolution may be needed. Most websites and online platforms will display images well when they are around 1200 pixels on the longest side. However, if you want to preserve the best quality for future editing, it's advisable to use no compression when initially saving your photos. With programs like Photoshop or Pixlr Editor, you can always compress the images later to decrease the file size while maintaining quality. Also, ensure that your subject fills the frame adequately and that the rule of thirds is applied to make the composition balanced and visually pleasing.
