If you use the save button the picture is saved as a .jpg file. Those files do not have the best quality. Especially red parts of your picture might look blurry. To avoid this you can save the pictures as .png files by making a screenshot in fullscreen mode:
- Windows Vista / 7 / 8 / 10: Use the “Snipping Tool” in the start menu. After you have cut out the area you want to save you need to select “PNG” in the “save as…” window.
- Windows XP: Press the “print” key on your keyboard, nothing happens.
Then open software like Paint or Photoshop. Click “edit”, “paste” and the picture appears. Maybe you need to move it around and cut the parts you do not need. Then select “PNG” in the “save as…” window.
- Mac: Press Apple-shift-4. You should be able to select PNG files in the options.
