First off...I would say completely forget about using f/1.8 for photographs of the boys...just don't venture i to that land of razor-thin depth of field and missed focus. At indoor ranges, f/1.8 is simply asking for pics with one eye in-focus, and the ears out. One nose in focus, one pair of out of focus eyes. At close distances, f/1.8 does not have any margin fort error. If you want shallow depth of field, indoors, you will have it with f/2.8. This shot of the boys eating their sandwiches is a cute family moment, but the over-exposure really hurts the shot. As badly as the one boy's hair is blown out, overexposed pretty badly, I think the right exposure should have been more like f/2.8 at 1/250. Getting the exposure right for the eyes?????? Not my idea of the way to approach this at all...I would say, get the exposure RIGHT for the highlights, and then use the superb shadow retrieval capabilities of a modern Nikon to "lift" the shadows "up" in post, and render the scene at the kitchen table beautifully. A simple, 5-second curves adjustment in post could have taken a much briefer exposure, like f/2.8 at 1/250, and made this shot a winner all around.
