contact sheet

every shot you took, all laid out on a single sheet.

negatives laid straight on the paper, printed at actual size — no enlargement, no crop. every frame side by side, to look over and pick from. that's a contact sheet. utsushi : 1 takes after that contact sheet, turning your own photos into one. pick your keepers, or lay related shots out like a diary — however you like.

the : 1 in utsushi : 1 is that one-to-one print.

monochrome

not a grayscale preset — rendered the way film would.

yellow, orange, red, green: one tap picks the filter, and its effect follows a real film's spectral response. yellow lets the sky sink softly; red pulls it deep. the tones ride the paper's s-curve into a deep black; how deep is up to you. the grain, too, shifts with brightness the way film does, and settles into the picture.

SPECTRAL MIX

film spectral response — the filter chooses which light weighs in.

PROOF TONE — H&D
toeshoulderlog exposuredensity

the paper's tone — an s-curve along the characteristic curve. shadows roll gently into deep black, highlights held just short of paper-white.

GRAIN
shadowmid-tonehighlight

grain strength follows luminance — dense in the mid-tones, quiet in the highlights. it rises with the light.

grease pencil

choose, by hand.

go through your shots in grease pencil, choosing as you draw. a circle, a cross — every stroke is your own. white, yellow, blue, and vermilion. what each color means is up to you.
