First 14 lines describe the photograph and then the final 12 (in parentheses) usher us deeper into the speaker's confidence with the first use of the 'I' pronoun.
"It was taken some time ago.
At first it seems to be
a smeared
print: blurred lines and grey flecks
blended with the paper;
then, as you scan
it, you see in the left-hand corner
a thing that is like a branch: part of a tree
(balsam or spruce) emerging
and, to the right, halfway up
what ought to be a gentle
slope, a small frame house."
(The photograph was taken
the day after I drowned.
I am in the lake, in the center
of the picture, just under the surface.
It is difficult to say where
precisely, or to say
how large or small I am:
the effect of water
on light is a distortion
but if you look long enough,
eventually
you will be able to see me.)"
