i would up the opacity on your nav bar. it gets hard to reference back to that once you've scrolled over a darker picture.
im not familiar with 4ormat, but do they have other options with their javascript? the lack of animation when using the arrow keys is a little hard to look at. not a huge deal though because the scrolling is really nice
and in your about page... "in front" not "infront".
Also people often tend to overlook the importance of the "about me" when writing it. I get that your going for minimalism, but i'm not really sure what it says about you and how it distinguishes you from other photographers. What are your goals of the website? Are you a freelance photographer? just like to share your work as a hobby? portfolio to get a job or into a school? It doesn't need to be explicit, just clear.
hope that helps! your work is really nice. you should be proud of it
