a photograph is flat
but it does not have to feel that way
depth is the sense of space
near
far
between
that is depth
what depth is
depth is distance made visible
foreground
midground
background
layers give the eye somewhere to move
without layers
everything sits on one plane
nothing stands apart
why it matters
depth gives structure
it separates
it guides
it holds attention
when depth is present
the subject comes forward
the background falls back
the image has space
without depth
everything competes
the image feels flat
the eye has nowhere to go
the mistake
beginners treat the image as a surface
they place everything on the same plane
same distance
same focus
same importance
the result is crowded
but shallow
what creates depth
depth comes from difference in distance
place elements at different distances
close
further
furthest
distance creates layers
one element in front of another
this is the clearest signal of depth
what is sharp feels closer
what is soft falls away
light separates planes
side light reveals depth
flat light removes it
objects become smaller as they move away
size suggests distance
how to use it
before you take the photograph
look for layers
find
something close
something further
something behind
then adjust
move forward
move back
change angle
until the layers are clear
what to look for
when you look at the image
is there a foreground
is there a background
do they feel separate
does the eye move through the image
if not
the depth is weak
once you can see light and space
you can begin to control it
