Help Have small front camera view - want original

[jkHIppie]

I have an LG K20 Plus. Somehow, I've managed to change the look of the front camera view (what I see on the screen when the front camera is selected). Instead of the original full-screen view (which I still have for the back camera), the screen is a pale peach (?) color, and the image is displayed in a small square in the center of the screen. I just want to reset it to the default look, but I can't find the right menu, or whatever. I'm a bit frustrated.
