I am a french photographer / designer.
I wrote a "photojournal" of my first roadtrip in Iceland
that i guess would be very usefull for those planning a similar trip:http://www.international-photographer.com/en/_roadtrips/iceland_2009/iceland_days_index.htm
(Click on a day to read the full story)
I wrote it in french, but because so many english speaking people were asking, it is, now translated in english.
You will also find some tools i design (guide, and a brand new map for photographers) that might help the travellers / photographers you probably are reading this.
I am excited to say that I go back in Iceland in 2 days for a full month, to make a new exploration... and improve my tools.
For those who like LARGE size pics (1600 pix), you can take a look at this gallery
