I know questions about Iceland have been asked before, and I've looked at them, but my question is slightly different. I've got two weeks in Iceland coming up (6/24-7/7), but I'm not sure where I should go in the country. So, with an eye towards landscapes and miscellaneous nature photography: What are the absolutely can't-miss, must-see, you-haven't-seen- Iceland-if-you-haven't-seen-x spots? General advice is also welcome (cheap car rentals, if such a thing exists in Iceland?), but I'm mostly looking for top 10 type stuff.
