Slide and Negative Identification
35mm transparencies come in a number of different sizes and formats
35mm transparency film can be divided into two different types, both using light to produce an image on a light sensitive emulsion on a strip of cellulose based film. Reversal film produced a positive image onto what was usually produced as individual 35mm slides. 35mm negative film produced an image where the colours were reversed and processed before being printed as a positive image.
The visible part of the transparency is 3.6cm x 2.4cm (about 1 3/8" x 1") and on show is a positive image. But this is not the only type of slide that we can scan under this service.
Provided the size of the transparency, when mounted, is around 5cm, then it comes under this scanning service. This includes: 35mm half-frame; 126; 127 standard; 127 super; and 110 slides.
The table below will hopefully help you identify what you have. All of the mounts are 5cm x 5cm. The sizes shown are the size of the visible part of the transparency.
|Variety of slide||Sizes|
|Standard 35mm Slide||3.6cm wide, 2.4cm high|
|Half-Frame 35mm Slide||2.4cm wide, 1.8cm high|
|126 Slide||2.8cm wide, 2.8cm high|
|127 Standard Slide||4cm wide, 4cm high|
|127 Super Slide||around 4.8cm wide, 4.8cm high|
|110 Slide||1.7cm wide, 1.3cm high|
The mounts themselves might be cardboard, plastic or metal. Your slides might be encased in clear plastic, or be glass plated. However they come, we can scan them. Even if your transparencies, are unmounted - cut into strips, or individuals - we can scan those too.
To make sure your transparencies come under the service of 35mm slide scanning, the part of the transparency showing an image is no more than 4.8cm square and a positive image is on show.
A positive image is one that displays colours that you would normally expect to see in real life. It's possible that these colours might have been degraded - they might have a yellowy or a blue tinge to them - but, thanks to our colour correction service, carried out as standard on all scans, even these can be rescued.
Ready to have your 35mm slides scanned?
Pictured is a strip of standard, 35mm colour, developed negative film. It is 35mm wide, and it's length is determined by how many frames there are.
Each frame shows a different image and the negatives, if colour, will be tinged red. Black and white negatives are tinged gray. Your negatives might be in strips as long as that pictured, slightly longer, or still just in one long film strip. They might be cut up indivivually. However you have them, we can scan them.
All you need to be sure of is that the strip is no more than 35mm wide and the negatives have been developed. You'll be able to tell if the negatives have been developed because - unless they're APS - they won't be in the canister any more and you'll be able to see some images if you hold them up to the light. The colours will be reversed, if colour. Or, if black and white, areas you'd expect to be light will be dark and vice versa.
But, we aren't limited to scanning just standard 35mm negatives. We can scan: 35mm half-frame; 126; 110; and APS negatives.
The table below will hopefully help you identify what you have. The sizes shown refer to the size of each frame.
|Variety of negative||Sizes|
|Standard 35mm Negative Film||3.6cm wide, 2.4cm high|
|Half-Frame 35mm Negative Film||2.4cm wide, 1.8cm high|
|110 Negative Film||1.7cm wide, 1.3cm high|
|126 Negative Film||2.8cm wide, 2.8cm high|
APS stands for Advanced Photo System. This may be written on the side of the film canister, or, if it's Kodak, it'll say Advantix. FujiFilm called theirs Nexia; Agfa, Futura; and Konica, Centuria.
APS film differs from any other type of negatives that we scan in that it will have been returned to you in the canister, after it'd been developed. Also, when you took the photos, you'll have been give three different options: H (High definition - which returned a 4" x 7" print); C (Classic - which returned a 4" x 6" print); and P (Panoramic - which returned a 4" x 11" print).
You might not know this, but, when each photo was taken, regardless of which option you chose, they were all taken as High definition. The film was clever enough to record which option you'd selected and an appropriately sized print was produced.
When we scan APS film, we scan each full frame. And, it's worth pointing out, in order for us to scan APS negatives, we will have to cut the negatives into strips beforehand. Don't worry, we're always very careful when doing this and you will still have the negatives safely returned to you.
When we scan any negatives at all, you get back a set of positive images on disc or memory stick. Finally, if you have both negatives and prints, it'd be worth your while having the negatives scanned instead: the results are generally better.
Disc negatives were introduced by Kodak in 1982 and were relatively short-lived. Each photo was taken on an exposure measuring only 8mm x 10mm. The disc itself was encased in a slim plastic case that had the advantage that any camera using them could also be very slim.
The disadvantages soon outweighed this advantage and Kodak officially stopped producing them just before the new millennium. They were difficult for photo labs to process and the cameras weren't built to take any extra lenses. But, scanning them at PiciScan is easy and customers who've asked us to do this have been pleased with the results.
We've seen some alarming videos on the internet about how this is done. If you have as well, don't panic: our scanning processes leave your disc negatives completely intact.
