What on earth is he on about I hear you ask. when taking a photo say of for example a bunch of flowers what happens is those nearest are in focus and those further way are not.
to overcome this it needs a series of the same photo but some the front in focus and others with those behind in focus. Then comes stitching them all together so now everything is in focus.
A long boring job with an editing suite.
Not any more a lot of cameras have the facility to do this in camera such as my Panasonic G9ii. So it takes about 37 photos in one go photographing at different parts of the subject matter and puts them all together.
this is something i have never experimented with before so it is also all new to me as well. easiest way is to use a vase (artificial in this case) to try out Photostacking
so here is my very first effort. those nearest and further away are all in focus
normal shot camera focused on nothing particular (camera in auto mode both times)
so now something I may well be doing in the future. Using electronic against using a manual shutter saves wear on any moving camera part
