"Light makes photography. Embrace light. Admire it. Love it. But above all, know light. Know it for all you are worth, and you will know the key to photography." -- George Eastman

The trick is knowing what can be made with available light.

That's true although the best smartphones have made pretty significant gains. I've been slowly working my way through my catalog of photos to clean it up and go back to a lot of my older phone photos taken in dim restaurants and the like and the photos were generally pretty awful.
