Before You Pay to Scan 2,000 Slides: How to Sort, Cull and Order a Loft Box (UK)
Maria C 
Before you pay to scan a loft box of 35mm slides, sort and cull it first. A typical inherited box holds 1,500–2,500 slides, and UK lab scanning is priced per slide — EachMoment's rate is £0.79 each, falling to about £0.48 with the deepest volume and early-bird discounts. That makes a full 2,000-slide box cost £952.74. But 30–50% of an amateur slide collection is duplicates, blanks, badly exposed frames and slides of people nobody can name. Remove those before posting and you cut the bill by hundreds of pounds without losing a single picture worth keeping. This guide shows you exactly what to keep, what to bin, what looks ruined but isn't, and how to order so you land on the cheap side of every price band.
Key takeaways
- UK slide scanning is billed per slide (EachMoment £0.79 base, floor £0.47), so the cheapest way to lower the bill is to send fewer slides — something no per-slide service is incentivised to tell you.
- A 2,000-slide box costs £952.74 all-in; culling to 1,200 genuine keepers costs £639.90 — a £312.84 saving for an afternoon's sorting.
- Never bin a slide for looking faded, dusty or dark. Dye-shift, dust and under-exposure are routinely recovered by a lab. Cull only true duplicates, blanks, lens-cap shots and unfixable blur.
- Watch the band edges: because discounts key off order value, 1,266 slides (£603.08) can cost £71 less than 1,265 slides (£674.56). If you land just under a band, add a few back rather than remove them.
- Keep slides in their carousels or magazines and number the trays — a good lab scans straight from the tray, and tray order is your only free metadata.
Slides to digital in the UK: your three options, briefly
There are three ways to get 35mm slides to digital, and the right one depends on how many you have:
- A DIY converter or phone gadget (£18–£160) — cheapest up front, but 8-bit output that clips shadow detail, and slow going for a loft box. Fine for a handful of slides, a false economy for thousands.
- A flatbed scanner with a film adapter (£100–£400) — better quality, but hours of manual work per hundred slides.
- A mail-in lab service (priced per slide) — the realistic route for a big box. UK list prices run from about 17p to 90p a slide across providers (MediaFix advertises "from 17p", Revive Studios 55p, The Slide Converter and Digital Converters around 90p, EachMoment £0.79 falling to £0.47 with volume). This is the option this guide prepares you for — because with per-slide pricing, what you send is what you pay.
Whichever route you choose, the prep below is the same, and on the mail-in route it is the single biggest lever on your bill.
Why sorting first is the only lever that lowers a per-slide bill
Every UK slide-scanning service prices the same way: a base price per slide that falls as the order gets bigger. On the live SERP for "slides to digital" you will see The Slide Converter and Digital Converters at around 90p a slide, Revive Studios at 55p and MediaFix advertising "from 17p". EachMoment's published rate is £0.79 per slide, dropping through six volume bands to a floor of £0.47 at the deepest combined discount.
Here is the part none of those pages spell out: they are all paid by the slide. A service has no commercial reason to suggest you send fewer of them. But the per-slide model means the single biggest saving available to you happens before the box leaves your house — in the cull. The lab will happily colour-correct a faded Kodachrome for you; it will never delete the 40 near-identical shots of the same Spanish cathedral, because it is paid to scan all 40.
| Slides sent | Volume band | Price / slide* | Order total | Saved vs 2,000 |
|---|---|---|---|---|
| 2,000 (no cull) | 33% | £0.48 | £952.74 | — |
| 1,500 keepers | 33% | £0.48 | £714.56 | £238.18 |
| 1,200 keepers | 25% | £0.53 | £639.90 | £312.84 |
| 900 keepers | 25% | £0.53 | £479.93 | £472.81 |
The chart below shows how the per-slide price steps down as the order grows — and the curious cliff at each band edge that you can use to your advantage.
The five-minute count: how big is your box, really?
You cannot make a cull decision without a rough count, and you do not need to count every slide. Use the geometry of the storage:
- Kodak Carousel tray — 80 or 140 slides per tray (the number is moulded into the rim). Count the trays, multiply.
- Straight magazines (Boots, GAF, Paximat) — typically 36 or 50 slides; a full one is about 9 cm of slides per 50.
- Loose in a box — mounted 35mm slides are ~1.3 mm thick, so roughly 75 slides per 10 cm of tightly packed row. A standard shoebox holds 1,200–1,500.
Write the number down. If it is over 1,266 you are already in the deepest 33% band, which changes the cull strategy — see the band-edge trap below.
What to cull: the six-category triage
Sort onto a lightbox, a bright window, or a phone torch behind a sheet of paper. Work fast and in six piles. The principle: cull for content, never for condition. A boring slide in perfect nick is still boring; a precious slide that looks wrecked is usually recoverable.
| What you're holding | Verdict | Why |
|---|---|---|
| Near-identical duplicates (5 shots of the same view) | Cull to 1–2 | Keep the sharpest and best-exposed; bin the rest. The biggest single saving in most boxes. |
| Clear, blank or near-black frames (test shots, lens-cap, end-of-roll) | Cull | No image data to recover. Hold to the light: if there is nothing there, there is nothing to scan. |
| Motion blur / camera-shake / out-of-focus | Cull (unless irreplaceable subject) | Blur is in the film, not the scan — no lab can add focus that was never captured. |
| Faded, magenta/orange colour cast, low contrast | KEEP | Dye-shift is recovered per-channel at the scanner. Looks worst, recovers best. |
| Dusty, fingerprinted, light surface mould | KEEP | Cleaned and Digital ICE-masked in the lab; most mould-damaged slides are still recoverable. |
| Too dark / under-exposed (looks almost black) | KEEP | A 16-bit lab scan lifts shadow detail an 8-bit phone or dongle scan writes as pure black. |
"It looks ruined" — the slides people wrongly bin
The most expensive mistake is throwing away recoverable slides because they look bad on a lightbox. Two of the three "cull" instincts are wrong. Drag the handle on these real lab before/after pairs: the left is what the slide looks like now (or through a cheap converter); the right is the recovered scan.
Faded and colour-shifted slides are the headline example. Reversal-film dyes fade at different rates — Agfacolor's yellow layer can lose around a third of its density in domestic storage — which is what produces the magenta or orange cast. Because the three colour layers are scanned separately, a lab rebuilds the balance from whatever density survives in each channel. The frame that looks the most hopeless on your windowsill is often the one that recovers most dramatically. (The exception is total dye collapse, covered in our guide to how Kodachrome scans back.)
Dust and surface marks are the second false alarm. A loft box collects decades of grit, but dust sits on the film, not in the image, and is removed by cleaning plus infra-red dust-and-scratch masking. Do not wet-wipe slides yourself — you risk grinding grit into the emulsion. Leave them dusty and let the lab clean them properly.
The band-edge trap: when sending more slides is cheaper
This is the counterintuitive bit, and it is worth real money. The volume discount is triggered by your order value, not your slide count. At the £0.79 base price, each band edge falls at a specific number of slides:
- 10% off from 95 slides (order crosses £75)
- 15% off from 190 slides (£150)
- 20% off from 317 slides (£250)
- 25% off from 633 slides (£500)
- 33% off from 1,266 slides (£1,000)
Because the higher discount applies to the whole order, the moment you cross an edge the total can drop even though you have added a slide. The clearest example is the top band: 1,265 slides cost £674.56, but 1,266 slides cost £603.08 — sending one more slide saves you £71. The same inversion, smaller, sits at every edge (about £22 at the 633-slide mark, £11 at 317).
The rule of thumb
Cull hard for content, then check your final count against the list above. If you have culled to just below an edge — say 1,240 — do not remove more. Add back your next-best 26 slides to cross into 33% off. You get more pictures and a smaller bill.
Don't dismantle the trays
A frequent and avoidable bit of work: people pop every slide out of its Carousel or magazine into a sandwich bag before posting. Don't. A proper lab scans straight from the common tray formats, and the tray itself is doing two useful jobs for free:
- Order is metadata. Slides were loaded in roughly chronological or per-event order. Once tipped into a bag, that sequence — the only context many unlabelled slides have — is gone forever.
- Trays protect emulsion. Loose slides rub face-to-face in transit. In their slots they don't.
Number your trays with a marker (1, 2, 3…) so the digital files come back in the same order. The equipment grid below shows the formats a UK lab handles directly — if yours is on it, leave the slides where they are.
Kodak Carousel tray
80 or 140 round trays (number moulded into the rim). Leave slides in. Number each tray.
Straight magazine
Boots, GAF, Paximat, Hanimex — usually 36 or 50 slides. Leave slides in, band the magazines together.
Loose card/plastic mounts
Standard 50×50 mm mounts. Box them upright in order; a rubber band per ~50 keeps sequence.
Glass mounts
Heavier, 3 mm thick. Flag them — they jam consumer scanners and need lab unmounting.
Stuck / blocked stacks
Damp-fused slides. Do not force apart — bag separately and let the lab separate them.
126 / 127 / Super-slide
Odd-sized square mounts. Keep them in a separate bag, labelled — they need a different holder.
Set the resolution once, and don't over-pay for it
One quality decision matters at order time: scan resolution. 35mm slides reward a real film scan — an effective 4,000–4,500 dpi resolves the grain of the film and prints cleanly to roughly A2. Going higher than the film's own detail just makes bigger files, not better pictures. The opposite mistake is worse: a cheap converter or phone gadget captures 8-bit JPEGs that clip the deepest two stops of shadow to pure black and resolve a fraction of the detail, so you pay to scan the box once and badly. If a slide is genuinely worth keeping, it is worth a 16-bit film scan the first time. Our measured slide-scanner test on a USAF-1951 target shows exactly how far consumer gadgets fall short of a Coolscan-class scanner.
You do not, however, need to add AI enhancement to every slide. It is a £4.99-per-item optional extra worth using on a handful of hero shots, not on 1,200 holiday frames. Decide your keepers first, then enhance only the few that will be printed big or framed.
Your pre-scan checklist
- Count the box using tray and thickness maths (above). Note whether you are near a band edge.
- Triage onto a lightbox into keep / cull / "looks bad but keep" piles. Cull duplicates, blanks and unfixable blur only.
- Keep everything faded, dusty, mouldy or dark — condition is the lab's job, not a reason to bin.
- Leave slides in their trays and magazines; number them so files return in order.
- Bag separately glass mounts, stuck stacks and odd formats, and flag them on the order.
- Check your final count against the band edges; if you are just below one, add back your next-best slides.
- Choose 4,000–4,500 dpi once, and reserve AI enhancement for a handful of hero frames.

How many slides are usually worth keeping from a loft box?
In a typical amateur collection, expect to keep 55–70% after culling. The rest is duplicates, blanks, test frames and unfixable blur. Culling a 2,000-slide box to about 1,200 genuine keepers is normal and saves roughly £313 at EachMoment's 2026 UK pricing.
Should I throw away faded or discoloured slides?
No. Fading and colour casts are caused by dye-shift, which a lab recovers by rebalancing each colour channel at the scanner. Faded slides often look the worst on a lightbox but recover the most. Only bin a slide for its content — duplicate, blank or blurred — never for its condition.
How much does it cost to digitise 2,000 slides in the UK?
At EachMoment's published 2026 rate of £0.79 per slide, 2,000 slides cost £952.74 after the 33% volume discount and 10% early-bird discount — an effective £0.48 per slide. Culling to 1,200 keepers brings it to £639.90.
Can sending more slides really cost less?
Yes, at a band edge. Volume discounts are triggered by order value, so crossing into a higher band lowers the rate on the whole order. Sending 1,266 slides (£603.08) costs £71 less than 1,265 slides (£674.56). If your cull leaves you just below an edge, add back your next-best slides.
Do I need to take slides out of their carousels or magazines?
No. A proper UK lab scans directly from Kodak Carousel trays and straight magazines. Leaving slides in preserves their original order — valuable metadata for unlabelled slides — and protects the emulsion in transit. Just number the trays.
What resolution should I scan 35mm slides at?
An effective 4,000–4,500 dpi captures all the detail a 35mm slide holds and prints cleanly to around A2. Higher settings only inflate file size. Avoid 8-bit consumer converters, which clip shadow detail that a 16-bit lab scan preserves.
The bottom line
Slide scanning is priced per slide, so the box you post is the bill you pay. Spend an afternoon culling for content — duplicates, blanks and unfixable blur — but keep everything that merely looks damaged, because fading, dust and under-exposure are exactly what a lab fixes. Leave the slides in their trays, mind the band edges, and you will pay hundreds of pounds less for a digital archive that still contains every picture worth keeping.
