Yeah, I'm working with a phone camera with badly scratched lens, here she is from the underside, the black blur at her face is a bug she's noshing onView attachment 774627
Can't make it focus on the large object in the center of the viewfinder no matter what I try.
I have that trouble with my phone camera, plenty of blurred spiders/plants etc and clear backgrounds. I found moving the camera further away as opposed to nearer focused it on the foreground instead of the background. Like @tintin40 says, just take loads and experiment.
