Regarding “taking off glasses being normal and accepted”. I don’t know if that is so or not, but personally, I am the only person I know who does it. I think most people do not do this, since most people who would care enough about it wear lenses.
According to the logic being used here with photoshopping, it definitely would be considered deceptive for me to take off my glasses – more so than with the photoshopping, since I never wear lenses and never take off my glasses.
What makes it okay is the fact that there IS NO deception taking place, since I would not hide the fact that I wear glasses from anyone. If anyone were to ask, I would tell them. I would tell someone before I married them if it were necessary (which it’s not because they will know the first time I meet them anyhow).
Here too, there IS NO deception taking place. If anyone wanted to know, they would tell right away that the pictures were photoshopped and explain the reason.
No one is denying the fact that in certain ways they dressed untzniusly in those days (although, they were much more tznius than we are today!).That is not why the pictures were photoshopped and it didn’t occur to them that anyone would look at it that way.
I don’t know how you could know that
