Hell, I’m no photographer… just found out what to do through trial and error.
You need a stable surface or tripod – I use a gorilla pod, or any flat surface available. Use the camera on self-timer so that pressing the button won’t shake the camera. Shutter priority and open the exposure time right up. That’s all I do.
I take lots of pictures and experiment a lot too. I discard about 95% of what I take, and try different angles and settings, even different image aspect ratios.
Just keep playing, but be bold and don’t be impatient.
Best wishes
Bob
