Questions you often ask…

What is resolution ?

In printing, the notion of resolution is essential : it definies the amount of information given for each dot of the picture. It is given in « dots per inck » or in dots per line.
For a high resolution, the quality of the printing is better. When sending files by mail a low resolution is better while for photo printing you will need high resolution image.

What is a pixel ?

A pixel is a luminous dot representing a picture on your screen. If these dots are small and close to each other, the resolution will be high. On the contrary, if they are big the resolution will be low.

Formats de fichiers pour la photo numérique ?

Jpeg : a good compromise.
The jpeg format offer a remarquable quality. This format compresses the pictures which means you will lose a part of the information. So you will need to choose an average compression.

Tiff : the quality.
Most designers choose this format to preserve the quality of the picture but these files are very heavy.

Raw
The raw picture is the one that you will find in the sensor. Keeping this format will enable you to have a file close to the original picture. This option is found in high quality cameras.
