smart format shop
In 2011, I started to make small prints in the format of 13 (approximately) x 15 cm (always). They come with a kind of 'digital polaroid frame'. You can mount them in a 20 x 20 cm frame without the need of a mat.
A smart format print could be a nice present for your loved ones or for yourself. You can also combine 2, 3, 4 or even more of them on a wall. See here some impressions
