So I am pilloried for trying to correct an incorrect definition of a core element of photography that I do by links and examples to world respected outlets?Its a toxic environment when there is always someone looking to either correct your grammar or just twist the meaning of what you say to start an argument.
You have a good dream of what forums should be.
I have been accused of bullying and mansplaining when all I have done is provided high quality link after link to facts. This might be a dumb forum and any of us might be entitled to our own opinions, however we are not entitled to our own facts.
Depth of field is a function of two factors, 1/ output magnification (how much of your angle of vision is taken up with the image), 2/ the size of the aperture used (the actual hole size not the f stop). The deciding factor of those two metrics is the CoC (how blurred a point can be before you consider it a blob). It is as simple as that. The logical extension of that is that if you make a picture smaller (move away from it) more of it becomes ‘acceptably sharp’. This is so simple to test for yourself it is almost unfathomable that so many of you are so wrong on this core photography issue.
Take a sharp picture, add a little blur to it so on your computer screen it is just not quite sharp. Now look at that same picture still with the blur applied on your phone. It will appear sharp again.
