For those in the know,
I am wondering what is the best direction to place a photograph on the scanner screen
portrait or landscape.
with the intention that the A6 (102 x 152 mm) foto print is eventually enlarged to a A2 size ( 420 x 597mm) about a 140% enlargement

or does it not make any difference

Whilst it doesn't make any difference in my experience, theoretically you'd want the long axis of the photo aligned with the scan head (the thing that moves), as that would result in most of the image being scanned with the head in one position and the least chance of misalignment between 'rows'.

So

+-----------+ <-- scanner
|           |
|           |
|           |
|           |
| +--------+|<-- photo
| |        ||
| |        ||
| +--------+|
+-----------+

If you're using non-proportional fonts you'll just have to guess at the above diagram.

Have fun,
Shay
