I would in no way criticise this approach and as I have said before its a matter of personal choice. The exception to my rule is if you are doing ultra close ups of Odonata, for instance the head then only the immediate area of focusing will be sharp, the remaining areas will be blurred but this accentuates the detail of that area.
You can set the depth of field in two ways. Firstly by using an aperture priority setting or secondly by a shutter speed priority setting. Both have their merits and disadvantages depending on the prevailing weather and subsequent lighting conditions. I will deal with this choice in greater detail in the next narrative.
The depth of field will be at its greatest and widest in bright weather conditions where the natural lighting is at its best. The higher the "F" number the greater the depth of field will be. In lower light or dull conditions the depth of field will be very much reduced and obtaining sharp images of the whole subject will be next to impossible and some compromise will have to be made.
