Thanks guys!
KV the camera is a 9 year old Nikon 990 Coolpix. Both the 1812 and Monongahela closeups were f2.5 @ 1/125 with flash. The Whaleboat was f2.5 1/60 with flash. All 3 were taken in automatic mode so just letting the camera make these choices.
Reducing the size of the aperture diameter, which is specified as the f-number increases the depth of field. The depth of field is that part of the image that is in sharp focus. The larger the f-number the smaller the aperture diameter and the greater the depth of field. Increasing the depth of field reduces the amount of light to the focal point. So if you want all of the image captured in sharp focus, in manual mode you use the largest f-number your lense and camera will allow and very good lighting.
Many new users of digital cameras are not aware that all digital cameras have shutter lag - Which is the time from when the shutter button is pressed until the image is captured. So you must hold the camera rock steady until the image is captured to get a sharp image. This varies by camera so just wait a second or so after you press the shutter button before you move the camera.
These 2 photos are small, but have a good depth of field although some of it is lost to some major cropping . . .
