It looks to me as if you're trying to get too close when taking the photo
I hadn't thought about that either LOL
The default Focus mode is an auto focus mode ( mountain icon)
The camera also have Focus Macro (flower icon)
I use the flower icon when I shoot flowers, but now that I read the manual I learned that I should use a tripod when I use the macro.
So next time I try to shoot flowers I will keep more distance and use tripod.
The camera has 3x optical zoom, and 2x digital zoom, but I did'nt use any kind of zoom.
Actually I never used zoom, so perhaps I should also read about that.. lol
I like the last flower so I used Corel paint to lighten it.
Also used corel paint on the next two photos.
