Welcome aboard Eddie.
Nice first post by the way – the resizing makes all the difference.
It’s difficult to tell where exactly the sharpest point of focus is
with this image because it’s a little bit soft overall, but well done
on capturing the moment. It’s all there, the trajectory of the ball,
the movement of the arms and feet. In spite of the soft focus
I’d call it a pretty successful shot. Well done.
I had a similar problem with resizing & the resulting softening image. Have a look at this thread at a freeware software package that resizes to your dimensions and allows for sharpening. It also includes batch processing. It’s an absolute Godsend :)
