You take a picture of your granddaughter and it’s precious by definition. Period.
I shot a lot of images – nearly 2000 – this day. Yeah, nuts! Meanwhile, I have learned a lot from shooting my cats. Call it practice for the big important things – the grandkids.
Move your lens in front of her eyes. A straight on angle makes it appear she is looking at you directly. You move. She doesn’t. You get more successful shots. Focus! The auto focus does the trick if it is told to focus on the eyes. The camera does not always automatically know.
Focus. The child is looking directly into the lens. It’s a start. Smile?! Cute!
