I tried using my phone(LG) but I noticed throughout the years my phone does not have much options when it comes to taking pictures. I didn’t see the sun on my LG phone camera, so I took these photos with my ipod. I did not know cameras on devices work that way, by adjusting the sun on the camera. I used my black sweatpants for the first 2 and a piece of paper from the last 2.
You seem to be able to make your photos darker but not lighter.
On the LG when you tap the screen and hold it, do you get any sort of icon? With theiPhone, a little sun appears on the right side of the area and you can slide it up and down. I bet the LG has something similar.
