What went wrong?

My scans look soft or blurry

Scans

What you're seeing

The whole scan, or part of it, looks soft even though the negative looks sharp under a loupe. Grain is not crisp.

Check this first

Check this first

Zoom in to 100 % on the scan and look at the grain. If the grain is sharp but the subject is soft, the film is soft; if the grain is mushy too, it is the scan.

Likely causes, most common first

  1. 01

    Film holder at the wrong height for the scanner's focus

    Common
    How to tell
    The whole frame is evenly soft, including the grain, on every frame.
    Test it
    Scan the same frame at each holder height setting and compare at 100 %. The sharpest grain marks the best height for your scanner.
    The fix
    Set all the holder's height sliders to the height that tested sharpest. On Epson V800/V850 holders the range is 2.5 to 4.5 mm and the best height can differ between frames.

  2. 02

    Film not flat

    Common
    How to tell
    Sharp in one area and soft in another, often the middle versus the edges, or one end of the strip.
    Test it
    Rescan with the film clamped flatter (covers clicked down, edges pressed) and compare the soft area.
    The fix
    Make sure film is not curled or pinched in the holder; flatten curly film in sleeves under weight. For camera scanning, flatness matters for edge-to-edge sharpness.

  3. 03

    The picture on the film is soft

    Common
    How to tell
    The grain is crisp in the scan but the subject is not, or only part of the picture is sharp. A loupe on the negative shows the same.
    Test it
    Look at the negative with a good loupe. If it is soft on the film, no scanner setting will fix it.
    The fix
    See the blurry photos entry for camera focus, shake and lens causes.

  4. 04

    Film moved or bowed between focusing and scanning

    Occasional
    How to tell
    The preview looked sharp but the final scan is soft, on scanners that autofocus. Or the scanner was knocked or is not level.
    Test it
    Set the scanner to focus again just before the final scan and rescan. If it is sharper, the film bowed after the preview.
    The fix
    Refocus at scan time (heat from the preview can bend film), keep the scanner level and still, and avoid multi-pass scanning on scanners that do not reposition accurately.

  5. 05

    Software softening from dust or grain filters

    Occasional
    How to tell
    Scans with infrared cleaning, grain reduction or heavy noise reduction are softer than scans without.
    Test it
    Scan the same frame with these filters on and off and compare at 100 %.
    The fix
    Use infrared cleaning only on dusty frames and at the lightest setting that works; use grain reduction sparingly.

Avoiding it next time

  • Find your scanner's best holder height once and note it.
  • Keep film flat in sleeves.
  • Refocus before each final scan on autofocus scanners.
