...are no excuse to stop taking photos with your smartphone!
As light levels fall, your camera might need some assistance to take sharp photos.
Things you should have to help get the best low-light images:
A tripod and/or mount. Suitable examples can be found on-line (sites like eBay.co.uk, etc.).
A dedicated long-exposure camera app. Search for "long exposure" and "slow shutter" in the App Store.
Also, you'll find that slow shutter speeds open up a whole world of new photo opportunities like motion blur and light trails.
Remember: Photos cost nothing so get lots of practice!
