Most often I go walkabout in a snap happy mood with camera but on this day I was relaxing in the sun so it was a case of shoot whatever is in sight from a semi- prone position which happened to be a field of daisies.
It was an opportunity to experiment with depth of field – particularly I was after the mid-ground with my DSLR zoom lens (14-140mm wide angle – medium telephoto)
Some basic factual tips on focal length from digital photo secrets*:
- the focal length of a lens is the distance between the lens and the back of the camera
- on a 55 mm lens for example this is also the distance between the lens and the spot where light focuses in front of the camera where the image is formed (nearly 6 inches for non-decimal thinkers like me)
- most human eyes focus at or near 50 mm, so that the focal point of our eyes is approx. 50 mm ahead (until we become short sighted and/or long sighted when the focal point is in front of or behind the retina respectively)
Thinking out loud with an aim to improve and learn more about photography. Hence the images are not always for show – feedback is welcome
