Oh, I still remember SOME of the hints and tricks my dad tried to teach us when we were little.
"Get closer" was definitely one of them.
"Fill the frame" goes with the first.
"Get some foreground" for landscape photography is another hint I remember clearly.
Later on I learned through trial and error.
Like when I first had the chance to use an SLR and could put on a 300mm lens, to only find out when the photos came back that they had all turned blurry.
That was when my sister explained to me that shutter speed would change considerably when you take photos with a telephoto lens. I had never even THOUGHT about that before! I remember how she said: "Imagine yourself looking at something through binoculars: you will find it really hard to hold it really, really still."
My sister also critiqued some of my early photos with the words: "Have there always been earthquakes when you where there?" Some of my pics were soooo crooked... !
So, yes, with me it's like with oldmacman, the hints and tipps and tricks came in little pieces, so it's hard to say which of those was the most valuable.
