Taking Pictures
During the event, Ji Tong will have a specific photo subject for each day. For example: "Red Item". Equip the Kurious Kamera gadget from your inventory, use it to aim at the requested colored item that you can interact with, and it will automatically take a picture of it. No need for any additional input.
Travelers will have 10 chance per day to take photos related to the requested photo subject. Taking correct pictures will give you a random colored photo as a reward.
You can then exchange for a reward from Ji Tong after you have collected 1 of each color. There are a total of 8 claimable treasure rewards for this event.
Photo Gifting / Photo Swap
In the events overview menu (F5 on PC), you can select "Photo Swap" to gift some photos to people on your friends list. If you have too many of a certain color, you can easily gift them to a different player, or you can request a color from someone else.
Red
Qingce Village has a lot of Jueyun Chilies that you can take pictures of. Each Jueyun chili plant has 3 of them, so you can take 3 pictures off of each plant.
Blue Creatures
Teleport to the teleport waypoint behind Andrius' area, and you can see 4 Cryo slimes nearby. This will give you 4 quick and easy pictures. You can fill the rest by going to Dragonspine area. Most of the enemies there have some blue to them.
Red Creatures
You can get 3 pretty easily by teleporting to the area near the Pyro Regisvine entrance. There are 2 Pyro Whopperflowers in front of the entrance, then get the third one by taking a picture of the Pyro Regisvine.
In Mt. Tianheng, there are 3 red archer hilichurls that you can take a picture of. It's near the cave with the Noctilucous Jades and it's not far from the teleport waypoint.
Teleport to Cecilia Garden domain that's to the west of Mondstadt, and you can take a quick and easy picture of 2 red hilichurls in front of the domain.
You can find the remaining 2 red creatures by going to Guyun Stone Forest. One is on the upper left teleport waypoint, and head east. The other is from the domain area, go outside into the hilichurl camp and take a pic of the Pyro Abyss Mage. Alternatively, you might find the remaining 2 simply by doing the daily commissions or just random exploration.
Brown Creatures
There are 3 brown hilichurls in front of the domain area to the left and right. Behind the domain door is 1 brown boar that you can take a picture as well for a total of 4 in this area. If you get a random world quest to save a reckless pallad, there might be some more brown monsters that you can take a pic of.
You can find 3 Geo slimes in front of the domain door in Guyun Stone Forest. Leave the cave from the front, and the Geo slimes are on the left side.
For the remaining 3 pictures of the day, you can find any brown hilichurls as you do dailies or traveling around.
