This is my first successful try with non automatic setting. I took about 150 pictures, only 15 turn out to be good. Exposure all good, but I need a tripod. Since shutter speed is so low with gym condition, I couldn't hold the camera with moving for a second. But really happy I got some nice ones.
I asked my pro teacher what's the secret to set the right exposure. Answer: just do it and learn. And, he is right.
This was shoot at f6.3. Shutter Speed 1/10. Light was terrible.
This was done automatic.
