|FROM THE CRITIQUE CLUB:
You've found a great subject. Now ask yourself, what's special about these, and how can I show their uniquely interesting properties, or make the artistic statement I am searching for.
To me, the white puffs work great where you have blue sky. They look soft, almost (perhaps stretching it to make a point) cloud like. If you could have found a direction to show a few of these against the sky, following good composition rules, you would be half way there.
Then there's exposure. That's definitely trickier with this white subject in bright sunlight. You have to watch for overexposure. In this shot, you have overexposed areas, which a histogram on your camera would have showed you, if the Optio S4 has one. If not, it's a great idea to bracket your exposures, once you have composed. Taken one 1 stop, or 1/2 stop lower, and 1 stop, or 1/2 stop higher, as well as the one your meter finds. Some cameras, like mine, have a bracketing function, where you set the range, and it will take three exposures when you press the shutter.
It's small enough I can't really judge focus here. But even if your exposure was right, you could have easily used a lower shutter speed and a higher F stop here to give you more DOF. 1/60 or 1/125 would have frozen any slight movement of the plants in the wind, and the higher F-stop would give you greater DOF.
This subject would make a great shot I believe, and would be good practice experience if the above is new to you. So what are you waiting for... ;-)
I hope this is helpful!!!!
