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 flash and additional light 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 galre with 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 and cause blur.
