    I'd re crop and take the worst of the oof trunk off. Would probably take a little off on the left as well to move the trunk more onto the third... more experience members on the forum will probably be able to tell you why it wasn't all infocus at the time.

      Hi Mike

      Interesting shot, and weird tree growth indeed...

      A basic rule is that the depth of field will increase with a higher 'f' number. Higher 'f' numbers mean the aperture is smaller, so you need more time exposure for the same amount of light to get to the sensor.

      Your shot was at f5.6. @ 1/200. You would have the same exposure level with f8 @ 1/100 and onwards, with each 'f' stop halving the amount of light, so you'd need to double the amount of time the shutter needs to be open. You can really increase your depth of field by using a tripod and using a remote shutter release to keep the camera steady, or alternatively, use a lens with image stabilisation. Both these will allow you to use higher 'f' numbers, requiring much longer exposure times, for the same exposure, but increased depth of field.

      When I bought my camera, I experimented in the garden. Keep the same ISO, set either to shutter or aperture priority, and take the same shot, from the same point at the same subject, but change the shutter / aperture setting. The camera will change whichever setting you are NOT changing, to keep the shot correctly exposed. You will see from your shots that the higher 'f' number shots have more in focus i.e. a greater depth of field.

      Hope that helps, and I'm not confusing you - sorry if I am though! Not easy to describe written down!

      All the best, and good luck. Mike.

        Thanks for the feedback and pointers, good to remember for each f stop 1/2 the shutter speed.
