The ISO i the same a film speed or ASA in a film camera.
F4 is the opening on your lens aperture
You should be able to adjust the shutter speed but only in TV mode or whatever Sony calls the shutter priority mode.

This tells you everything that was going on in your camera when you took that picture.
Taking someone elses picture and adjusting it without permision i a serious breech of etiquette.
That's what I should have done though instead of posting my pictures. I really wasn't showing off.
Since I've already done one rude thing, I might as well and break the rules again and show what could be done with a little playing.
This is one of your pictures
