proposal for small improvement on digicams

Last year I bought a digital camera (4Mpixel, 3x optical zoom). I'm
satisfied with it, near 3200 shots to date.

Having the possibility of shooting a much larger number of cheaper pictures,
I'm trying to improve my photo skills. Time ago I realized that there should
be a small improvement to apply on this type of camera in order to enable
the ordinary photo-amateur, like me, to improve pictures.



Let me explain with an example: suppose you are pointing to human subjects.

The subjects are not so close to the camera because they are many, or
because you want also some landscape in the picture, and so you cannot
easily observe each movement in the image without an hawkeye.

In another example also children are not steady during snapshots, so
sometimes you have to take some continuous shots and discard those that you
don't like.

It should be very nice if you could observe some portions (say the faces) of
the subjects enlarged, immediately before taking the photo, obviously
keeping the original image frame as it was.

Observing the enlarged image you could wait and decide when the subjects are
in the best shape for taking the picture.

Obviously you could also tele-zoom on the subjects, return to the original
view and shoot, but this takes time and the subjects would move during this
process.

I think that this function should be realized on a digital camera with
modifications only on the camera firmware.

Indeed I think that when you "zoom" an image the movement of the lenses in
the viewfinder is indipendent from the motion in the front lens. That is,
there is no mechanical link between the two actions, only two indipendent
micro servo actuators for the two set of lenses. I'm I wrong ?

Suppose that setting a "Portrait mode" program with a distance to the
subjects (center area) greater than say 2,5 meter automatically enables this
new function.

Pressing halfway the shutter button, the camera focuses on the subjects, as
usual. Then it "knows" (from Portrait mode + distance> 2,5 m) that enlarged
subjects details are needed. So the camera enlarges the subject (center)
area only in the viewfinder and displays it. The front lens doesn't move and
the camera is ready to capture the original image.

Now all you have to do is to observe the details on the viewfinder (you can
still see the full image on the LCD screen) and decide the best moment fully
pressing the shutter button. After the taking of the picture the viewfinder
should return in sync with the image from the front lens.

This feature already exists on the Panasonic FZ range of cameras,
when using the manual focus feature.

If your camera allows you to take pictures in burst of three or so, I suggest you use it,
then keep only the best picture.

My camera, Olympus C750, does this during manual focus.
