You will need:
Create a scene using your chosen still life subject under a constant light source such as a desk lamp. Turn off all auto features (such as face recognition, exposure bias etc.) and set your camera to capture in RAW+JPEG
Turn your camera to manual and set the aperture to f8. Using ISO and shutter speed adjust these until you get the image with the best exposure (I would suggest starting at ISO 800, shutter speed 1/125).
Post your unedited (resizing is allowed) results below along with your camera settings.
