For long exposure shots, you want to choose a low ISO sensitivity and a slow shutter speed (hence the long exposure) along with the aperture set to f/2.4.
You can start off with an ISO of 50 and a shutter speed of 4s. Depending on the results, you can then tweak your settings. 💯
Iso:200 Exposure:-2 Shutterspeed:10sec Aperture:f1.5. These are the settings.. You can either click an image every 10sec or download intervalometer app from playstore. Later open all photos clicked as a sequence in photoshop and merge it.
