Sun Printing

 Do you know sun printing?

For this fun technique you need special nature print paper

(like here, here or here)

which is also called solar photo or sunprint paper.

You arrange your items on the paper

and expose it to the sun for a couple of minutes.

It will then look like this:

The exposed spots have turned very pale 

and where your items lay the blue remains.

Then follows a short water bath

that will "develop" your prints

and reverse the colours:

Magic, isn't it?
