To get better photos, I asked kids to keep the sun on the back so they can keep the eyes open. However, as there was significant back light, I knew the photo will be very dark. So I quickly changed Exposure Value compensation on my Samsung Note 4 phone. As the bell had rang, kids were rushing to get back into the close so I didn't have lot of time to fine tune exposure. I just move it to some positive value and took the shot. As you can see below, the photo came much better. YOu can see kids and their super hero t shirts better. It is not a perfect photo but it would work to share with other parents and save the photo for memory
Isn't Trial and Error photography easy and effective?
