How to Make a Contact Sheet from Film Negatives

The darkroom method step by step, the proper-proof exposure, and how to build a digital contact sheet from scanned negatives that still reads like a roll.

4 min read

The contact sheet started as a film thing, and for film photographers it still is: a positive print of the whole roll that shows what is on the negatives before you spend paper and an afternoon on enlargements. There are two ways to make one now — in a darkroom, exactly as it has always been done, or from scans. Both are below.

What you need in the darkroom

  • Developed, dry negatives, cut into strips — 35mm in strips of five or six frames, 120 in strips of two to four depending on the format.
  • Photographic paper, traditionally 8 × 10in. Resin-coated (RC) paper processes and dries quickest, which is what you want for proofs.
  • A sheet of clean glass a little larger than the paper, or a contact printing frame.
  • An enlarger to use as the light source, with an empty negative carrier.
  • Developer, stop bath, and fixer, a safelight suitable for your paper, and a timer.
  • A grade 2 filter if you are using variable-contrast paper.

Step by step

  1. Raise the enlarger head until the pool of light covers the paper with some margin to spare. Set the lens to around f/8, and put in the grade 2 filter if you have one.
  2. Under the safelight, lay a sheet of paper on the baseboard, emulsion side up.
  3. Lay the negative strips on top, emulsion side down — the duller side of the film against the paper. Emulsion to emulsion is the rule, and it is what makes the frames read the right way round.
  4. Lower the glass over everything to press it flat. Any gap between negative and paper and the frames print soft.
  5. Make a test strip first: cover all but one band of the paper with card and expose in steps, moving the card along every few seconds, so you get a row of increasing exposures.
  6. Develop, stop, fix, and wash according to the paper's instructions — around a minute in the developer is typical for RC paper.
  7. Read the test strip in normal light, choose the time, and make the full sheet.

The proper proof: choosing the exposure

Use the clear edge of the film — the rebate — as your reference. Pick the shortest exposure at which the rebate prints as a full, rich black, no lighter than the band beside it. That is a proper proof, and it is the most useful thing in this guide.

A proper proof shows you how each negative actually prints at a standard exposure. Thin, underexposed frames look pale and empty; dense, overexposed ones look dark and muddy. That is exactly what you need to know before printing, so do not adjust the time to make the frames look nice. A contact sheet that flatters bad negatives hides the one thing it exists to show.

From scans: a digital sheet that still reads like a roll

If you scan your film — on a flatbed, a dedicated film scanner, or with a camera and a light source — you can build the contact sheet from the scans instead. It costs no paper, it can be emailed, and you can rebuild it any time.

  1. Scan every frame, keepers and duds alike. A sheet of only the good frames is a portfolio, not a contact sheet.
  2. Export JPEGs at around 1,600px on the long edge. A thumbnail never needs more.
  3. Name the files by roll and frame — roll-014-frame-07.jpg — so a frame on the sheet points straight back to a strip in a sleeve. The batch file renamer does a whole roll in one pass. Pad the numbers so frame 10 does not sort before frame 2.
  4. Open the 35mm roll template: landscape, six across and six down, on a near-black page so it reads like a darkroom sheet. One 36-exposure roll fits on one page.
  5. Put the roll number, film stock, and date in the header, then download the PDF.

Grids for other formats

Set the grid so one roll fills one page. That keeps the sheet and the negative sleeve in step, which is the whole point of filing them together.

FormatFrames a rollGrid for one roll a page

Leave image fill off for film. Fill crops every frame to the cell's shape, and on a contact sheet you want to see the full frame — including what the edges caught.

The quick hybrid

Two shortcuts if you want something in between. Scan an existing darkroom contact sheet on a flatbed at 600dpi and you have a digital copy to email. Or lay a full negative sleeve on a flatbed with a transparency lid, scan the whole page as a negative, and invert it: rough, but a usable index of the roll in a single scan, before you commit to scanning frames properly.

Common questions

What size paper do you use for a 35mm contact sheet?
8 × 10in is the traditional size. A full 36-exposure roll fits on one sheet when it is cut into strips of five or six frames.
Which side of the negative goes down on a contact sheet?
Emulsion side down, against the emulsion side of the paper. The emulsion is the duller side of the film, and film tends to curl towards it. Printing emulsion to emulsion makes the frames read the right way round.
What is a proper proof?
A contact sheet exposed for the shortest time that prints the clear film edge as full black. Because every frame gets the same standard exposure, it shows you honestly how each negative will print, rather than flattering thin or dense ones.
Can I make a contact sheet from scanned negatives?
Yes. Scan every frame, export small JPEGs named by roll and frame number, and lay them out six across and six down on a landscape page so one 36-exposure roll fills one sheet. A near-black page background makes it read like a darkroom print.
