I'm not into pictures like that, I'm a shop/tool guy. My wife was taking pictures with her iPhone and I just pulled mine out and shot one for laughs. The picture is taken when the finger is lifted from the button. I just try to hold still, hold my breath on exhale as if shooting a rifle, and gently lift my finger. If it is a picture I really want, I'll take three or four shots. I can look through them to find one that is nice and crisp.
THIS SUCKS! Looks like I have an aphid infestation in my garden. Time to break out the spectracide. I just hate to use this stuff because it will most likely kill the beneficial bugs also but the aphids have overrun my plants. I have no other options at this point. RIP good bugs. Collateral damage or casualties of war, I guess.
