I walk a lot during the day, and since I live in a tropical climate, the sun can get quite bright with clear skies. The screen can get illegible during these times if I don't set it at its brightest. Indoors and during the night, keeping it halfway is good enough.
I think a shortcut for brightness at the homescreen is definitely not an absolute necessity, but it would improve usability a lot.
Pics please. I am interested in this case as well. Thanks!
Pictures are available in many places, just searched on Google or you can go to the brand's official website:)
I'm using the brown one too, fits perfectly and looks really gorgeous on my dx90
