I have been taking pictures for many years (not as many as Mark12) and one thing I have learned is that human nature is to take, if you put something in front of them, they will take it.
Imagine going to Duxford and all the stalls are not manned. No one to take your money.
What would you do?
If you are going to present people on the internet with pictures or video clips, you have to make sure that if people take a copy of them, they can’t do much with them.
There are ways to make the image big enough on the screen, but if you try to print it, it would almost be postage stamp size.
I am amazed at some of the images that have been posted on this forum.
I have come across some pictures that when printed are almost an A4 print!!!
Big may be beautiful, but it can cost you.
