Tasseren at Dueling Peaks Stable would like to paint a picture of Hyrule's finest sunrise, which he says you can see from the top of Tuft Mountain.
Quest Location
Check on the empty frame on the wall in Dueling Peaks Stable to start this quest.
How to Complete the Quest
Tuft Mountain can be found in southeastern Hyrule. It is south of Rabella Wetlands Skyview Tower. Go to the top of the mountain, and if it is not morning, you can drop some wood and flint on the ground and hit the flint with a metal weapon to start a fire, then examine the fire and choose to sit until morning. Then you can aim your camera to the east, where the sun is rising, and take a picture. After you take a picture that has a red exclamation mark symbol on it in your album, go back to Dueling Peaks Stable and check on the empty frame again to complete the quest.
Quest Reward
Tasseren gives you a Pony Point, and a Hasty Apple Pie. If this is the last painting to go up, you also get a Diamond and five Enduring Carrot Cakes.
