It would be nice to know what type of camera you have but there is usually a button for this, mine has a blue arrow pointing at the button. You can usually zoom in and out as well . Good luck!
It depends upon the camera but most have a little arrow looking button somewhere that looks like a play button of a remote control. With the camera on, clicking on that button which looks like a play button will usually do it. Scrolling between images is usually done with the buttons that allow you to scroll through your menu.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
