This is obviously one of the primary things to learn about in order to make a photo have some, well, depth...
It was this aspect of a picture that really got me eager to try developing skills in photography - I was fed up with "phone-pics" being flat, busy and just like everyone else's; sure you can do some cool stuff with a phone camera, but just not enough for my taste.
This was taken just along the road from my house when the autumn colours on certain deciduous trees really come alive . It's also my favourite time of year!
I was actually trying to focus on the closest, big red leaf...it wasn't until much later I discovered why I was having trouble getting my focus point correct (I even went for an eye test because I thought my eyes were broken). Turns out I hadn't set the viewfinder focus properly for my eyesight! 😳
What I learnt from this shot was the way we can move the eye through a picture by changing from an obvious point of focus to somewhere else in the frame.
If I had got the focus correct; as I had wanted initially, the eye would have stopped at the red leaf...and perhaps the rest of the shot would have been lost in the blur of the background; which is fine, if you're trying to isolate a certain thing from its background - I was just trying to get something in focus manually!
With the focus actually falling behind onto the yellow/orange leaves, it pulls the eye in more, beyond the obvious foreground detail of the big red leaf. By creating layers of perspective, it gives the image depth, but still uses a shallow depth of field - something I wouldn't learn about specifically, until much later and there after, understand what I'd done.
