("muchly", I found a new word to add to my vocabulary to frustarte my 5th grade english teacher

I have been thinking about this muchly and here is my thought;
Someone in reference to his photography asks about adding "perspective", changing the "perspective" or however they phrase the question.
His understanding may be in line with how you have defined it, or it may not.
The same person may have the understanding that "perspective" is the 3D illusion that some pictures have.
So do we tell the person they are incorrect when it comes to photography, do we tell this person that "the only thing that determines perspective is distance". I suppose we do, since that is the consensus of this thread.
I would hope if this person comes across an article that can take their photography to another level it doesn't hold that individual back from reading it because it is entitled "perspective" and the author has a different understanding of the definition. How can we have respect for this persons teachings if their understanding of the simple word "perspective" is different than ours. Just as in painting a photograph can have the illusion of depth by altering colors, changing light intensity, shadows, changing the areas in focus and altering the dimensional aspect and position and placement or location of objects. The difference is we have far less control on those aspects than someone painting. If someone describes these things as a way to control perspective in photography should we dismiss their teachings as they do not know what they are talking about?
I think explaining to someone that a 7D sensor does not have more "Reach" than a FF sensor, or that a EF-S lens at 100mm is not a 160mm in disguise, is a little more straight forward than describing "perspective". Again as you said "my opinion" thank ya muchly. ;D
