Just after sunset is a great time to photograph. I did not bring my tripod on the backpack so I had to rely on larger aperatures and a wide angle lens to bring the shutter speed down to a managable level. I rarely shoot landscapes with an aperature less than f9.5 but because I had no tripod, I had no choice. Even using my lens wide open (f2.8) with a 1/15 sec shutter speed can produce a good photo.
