Blurry edges and how to stop them
Hi fellow photographers
Here are three pics and all of them have a blurred area on the photo.
The girl hanging from the bars - her right hand is blurred while the rest of the photo foreground is in focus.
The large fan leaf - the left bottom corner where the stem begins is out of focus
And the orchid - the top flare of the flower is out of focus.
How do I keep all of the image in focus please? As much info as possible would be greatly appreciated.
Many thanks
Bruce

The first is probably due to shutter speed.
The others look to be more DOF issues, where a smaller aperture would of helped.
Yep. The hand was moving. The rest are just DOF. And EXIF would help to confirm this.

In a little more detail:
Your shutter speed was 1/160 in the first pic, that's slow for "action". I think you were at or near your maximum aperture, but you could have bumped the ISO to 200 to achieve a higher shutter speed, maybe 1/250 to 1/300, which might have been just fast enough to top the motion blur in her hand. It looks like the light was weak so you may not have been able to do much more, you may have had to choose between (1) a little blur or (2) noise at a higher ISO or (3) underexposure.
The issue in the other 2 pics is probably depth of field. Your exposures were respectively f6.3 at 1/125 and f5.8 at 1/80, ISO 200 in both. I don't know your camera but you probably have a max aperture of at least f8 which would give you more depth of field, maybe enough to give you focus throughout the depth of these subjects. You probably wouldn't want noise at a higher ISO so you would need longer exposures - definitely calling for a tripod, or better lighting. Alternatively or in addition, greater distance from your subject would give you more depth of field.
EXIF shows you used "Creative program biased toward depth of speed". I've no idea what THAT means, but you could use shutter priority in the first pic to choose a higher shutter speed and aperture priority in the other two and set the ISO at 200 rather than auto for all of them (or try a higher setting to see how bad the noise is). Or full manual control.
By the way, I use the ViewEXIF program, free at http://ak.no-ip.com/
to get info about the pictures. Info is available sometimes, as for these pics, but may not be if a pic has been processed - depends on the software used.
