I am curious whether or not anyone has experience with pictures and videos. I often see images but I do not know what to believe. Is what I see fiction or reality? Does anyone know how to decipher these images/videos from truth or fiction?

well basically that's what this site is here for... to try and figure out truth from fiction...

as for deciding if a picture is real or not, you need to look at several things, quality, lighting, exposure, pixelation. unfortunately i'm not an expert on this stuff, so i cant explain any of it. hope this helps

What Nethius has said, pretty much ties it up. You could always look online for a photo expert. I'm sure they could tell you whether or not something has been faked. In most cases it is very obvious, but in others, even the experts have problems.
