Lighting
Lighting greatly affects the quality of the resulting photo.
Best results can be achieved with bright and evenly distributed light, preferably daylight. On a
bright sunny day, you can increase the aperture number to get a sharper picture.
Using a flash and additional lighting sources
 When using artificial lighting, use two light sources positioned so as to avoid shadows or
glare.
 If there is enough light, turn the flash off to prevent sharp highlights and shadows. When
using the flash in poor lighting conditions, be sure to take photos from a distance of
approximately 50 cm.
Important! The flash must not be used to take pictures of documents printed on glossy paper.
Compare an image with glare and a good quality image:
If the image is too dark
 Set a lower aperture value to open up the aperture.
 Set a higher ISO value.
 Use manual focus, as automatic focus may fail in poor lighting conditions.
