My 94-year old father, Karl, doesn't get a chance to see his 2-year old great grandson, Kane, very often as Kane lives in Hong Kong while my father lives in Toronto, Canada. My dad still lives alone in the house I grew up in. Fortunately. my brother lives about a 5-minute drive away from him, so he has help available when he needs to get out as he gave up driving when he turned 90.
I've taken to putting a Speedlight in my camera bag when I'm on the road for use in these types if situations. We all got together at my brothers house for a few hours last week. Getting a shot of Kane with my father was a priority. Bouncing the Speedlight into the corner of the room was all I used to light the shot.
