LCT: photo spots and the light
LCT knows 37,000 shooting locations across China. Check when the sun rises there and when blue hour starts before you leave, and spend your time on site actually shooting.
Worked out on your device for today, Beijing time (UTC+8), ±2 minutes.
Today's light, worked out now
The place card at the top of this page is live. Pick another spot and your browser recalculates it for today, to within two minutes.
How others shot the same spot
Photos from one location sit side by side, so you can see where people stood, what time they went and which settings they used.
Posts go through keyword filtering and review. That layer isn't ready yet, so for now it stays switched off.

Questions
Is an LCT account shared with Mark or Zlens?
No. An LCT account only works on LCT. Mark, Zlens and MuseFrame each keep their own.
Where do I sign up and log in?
Inside the LCT app. Locations, weather and light times are readable without logging in.
What if my location isn't in the database?
LCT says so instead of making one up. Location data ships in packs, and a bad pack is rolled back whole.
When does the community open?
No date yet. This page only covers what's deployed today.
The web app works today, and you can look up places without an account.
