I just got a Kodak Scanza ("digital film scanner") brand new, no cost to
me. It calls itself a scanner, but it would appear to be a camera
designed for slides and film negatives. It doesn't "scan" to a computer,
you need to have a SD card installed and it writes to that. There's a
backlight and a pair of slots for different size film holders, then you
can see the photo on the screen and click a button to "scan" (seems more
like photograph) it.

I bought a San Disk brand 64GB SD card, stuck it in the Scanza and did a
roll of film as a test case. Easy enough to use, but limited options on
device. Anyway, I pulled the SD card out and tried to read it on my
Linux system and it would not mount.

# ls -l /dev/sdb*

#

Well, that's odd. Usually these come with working filesystems, and the
Scanza had no error messages. I tried again with a different card
reader, now it showed up as /dev/sdd, /dev/sdd1, but still not working.
Let's reformat.

Great, now Linux mounts it, shows empty filesystem.

I umount it, stick it in the Scanza, and it tells me the card is
unusable with a vague "CARD ERROR" message. There's no option to
format SD cards on the Scanza, there is a card info tool, which shows
the capacity at 0MB good for 0 photos. (Before the reformat, the
capacity was ~6700 photos.)

Are there tricks I should know to format an SD card so that a stupid
hardware device can use it? All I'm finding in searches is formatting
for dummies.

Try -t exfat instead of -t vfat in your mount command, based on that
partition type.

Snipped the command output. Most likely the scanner is old and can't handle
a vfat filesystem with the cluster size that is being used.
See https://www.ign.com/wikis/nintendo-3ds/How_to_Use_SD_Cards_Bigger_Than_32GB
for one example.

Try "mkfs -s 64 -t vfat /dev/sdd1". If that fails try 32, etc. It must be a power
of 2.

If that still doesn't work you'll probably have to use a smaller sd card.

That's not a valid filesystem type for mkfs. (And people wonder why
Linux is hard.)

# mkfs -t exfat /dev/sdd1
mkfs: failed to execute mkfs.exfat: No such file or directory
#

Someone besides me probably knows what the "v" in "vfat" stands for, but
my guess is "various".

Anyway, that error went away when I repartitioned.

I gave up guessing the type, Now all I use is -t auto to let mount
figure it out anytime I do not know the FS type.

Yeah I've seen that happen with my oldest devices. This has a copyright
date of 2017 on the box, Amazon shows "frequently bought together with
128GB card" and the Q&A at Amazon has a "I'm using a 64 GB card" answer.
Plus, it worked (but Linux didn't) with the original format on this
card.

> Try "mkfs -s 64 -t vfat /dev/sdd1". If that fails try 32, etc. It must be a power

I tried 64 32 16 8 4 2 then 256 (mkfs gave an error) and 128. All the
ones that actually formated failed. My actual command line looked like:

mkfs.fat -s 64 /dev/sdd1 && mount /dev/sdd1 /kodak && df -h /kodak &&
umount /kodak

Since plain mkfs was getting confused by your version.

For good measure I tried reformatting with first sector at 8192 and
32768 (recall that the card came with first sector at 32768, while fdisk
defaults to 2048). And formatting the card to have a single partition
under 30GB. Also no luck.

> If that still doesn't work you'll probably have to use a smaller sd card.

It's possible this brand new SD card is bad out of the box, but since it
works with Linux and it's brand name, from a brand name retailer, I'm
feeling that it's likely a format issue still.

On Mageia 8 ...
$ ll /sbin/mkfs.vfat
lrwxrwxrwx 1 root root 8 Feb 12 2020 /sbin/mkfs.vfat -> mkfs.fat*
$ rpm -q -f /sbin/mkfs.vfat
dosfstools-4.1-3.mga8

As it's not working with the specified cluster sizes, it's probably the reader
can not handle that size.

It's a Microsoft filesystem. Linux let you use any filesystem you
want when with Windows, you have to use only the Microsoft
filesystem. In a way, it's easier, but because it's limited.

You need to install the drivers first. Check with your package
manager, I'm pretty sure they are available.

Since you then format the partition with FAT32 instead of exFAT,
the correct partition type is 'C', not '7' -- Linux doesn't care
about partition types but the Scanza probably does.

If after changing partition type to 'C' it still doesn't work in
the Scanza you'd probably have to install exFAT support and format
the card with exFAT.

mkfs.exfat is part of the exfatprogs package on Debian. There's
probably something similar for your distro.

From the operating manual, it appears that you are not /meant/ to
transport the SD card to your computer. The Scanza has a "USB Upload"
option which "will allow you to access your SD card (not included)
from your computer."
(See https://www.kodak.com/content/products-brochures/Consumer/KODAK-
SCANZA-Film-Scanner-Manual.pdf)

My guess is that Kodak reformats the SD card into a proprietary format
on use, and does not expect the card to be shared among devices (at least,
among non-Kodak devices).

DING DING DING That was it. Changing the type worked.

Here's a sample of the Scanza output. This is (was) my dog Bo, taken
about 15 years ago, with a Minox LX. That camera uses 8x11 mm film, I've
told the Scanza it is 110 film, which is 13x17mm, and cropped the
"scanned" image, but I haven't resized or adjusted colors. The Minux
tends to overexpose due to modern batteries being a slightly different
voltage than the ones it was designed for.

https://qaz.wtf/qz/img/scanza-bo.jpg

For comparison, this is the same picture, scanned from the print with my
Epson ES-50:

https://qaz.wtf/qz/img/epson-bo.jpg

Even though the Scanza image is much higher resolution, the quality is
pretty bad. That's a very muddy image.

Well if you want quality invest in a negative scanner.
E.g. this is a scan of a 1941 negative...

Which scanner was used? How much did it cost? How fast is it? How easy
is it to use?

Like I said in the first post, this Kodak Scanza cost me nothing. It's
very easy to use (modulo getting the SD card to work). It's pretty fast.

I have an Epson Perfection 4490, which is at least a decade old, perhaps
more. It can scan negatives and slides, using a backlight in the lid. It
was why I selected that scanner. It's really slow to use and kinda
tedious doing negative scanning, which is why I thought I'd try the
Scanza out.

I bought the Epson EM-50 because I needed to scan a big stack of legal
documents, and it's not a great scanner but so easy and fast to use. But
the EM-50 only scans stuff that feeds through and reflects light. I also
find it _really_ needs something white to get a good color balance. The
Minox prints work well because they all have a white border. Other
photos, not so much.

I've got 100+ year old glass negatives that are photos my
great-grandfather took. I haven't tried them in the Perfection 4490.
I've been meaning to make a plate holder to use with the scanner, but I
have never gotten the round-tuit. (I'm not sure it will work. The
backlight for transparancies isn't the full width of the scanner, and
the glass negatives are bigger than the ones it is desgined for.)

One of the better ways to get a slide like that digitised is a light box
and a digital camera, with a decent accurate lens. (no barrel or
pincushion). Once set up a box of slides is very fast to get through

Yes, there are some film "scanners" like that, I have one. Very fast,
but not very high resolution. Then you can use a proper scanner on those
few photos worth it. Some of those scanners take 5 minutes per photo. So
it is a compromise.

Way too big :-)

Are you ever going to scan 6700 photos on one go? Typical usage is to
scan a roll or two, then transfer to the computer, and erase the card.

Why do you tell it to mount vfat, instead of letting Linux find out what
filesystem it actually has and mount that? Let computers work for you,
not you for the computer.

It is probably exFAT.

Yes, openSUSE has it:

/usr/sbin/mkfs.exfat
/usr/sbin/mount.exfat

Of course it does.

The rule of thumb with cameras is: let the camera format the card. Don't
format them on the computer.

Typical for how I was using digital cameras (when I regularlly used
digital cameras) was take photos, copy, but not delete, photos off the
card and continue until the card was full. Then get a new card. That way
I have multiple copies of photos and I'm not rewriting the same area on
the card over and over.

If the quality was nice, I was planning to do a few thousand photos,
maybe not 6000. But the quality is so disappointing.

Just get a copy on two hard disks, proper hard disks. Consider cards as
"ephemeral memory", something not reliable, for temporary storage only.
For transferring from one place to another.

The scanner will not work well with that many photos stored, anyway.

Just copy them to two hard disks with proper archiving structure and
metadata. Don't do any editing on the card.

I have a Reflecta x7-Scan, which claims to do 3200*3200 dpi. In reality,
it is just a 13 megapixel camera, or 2994*4416 pixels for 35 mm film. On
other film sizes it does less pixels, ie, it trims them.

That is, "on 110 film, which is 13x17mm", the quality must be terrible,
unless the lenses do a zoom. You can find out the actual pixel count you
get. Wait, so I can.

I downloaded your photo:

I think that anyone's optimal strategy should be primary disk, backed up
once a night to secondary disk *and* disk at remote location.
If you want full 'restore to yesterday' functionality.
Handle audit trails and versions independently.

What it boils down to is that grain size in ancient negatives should be
comfortably above pixel size in the scans..

For this I had moderate success with placing the backlight from an
LCD screen on top of a clear plastic tub and a (in my case) large
photographic slide under the tub. With this on top of an ordinary
scanner the results seemed to depend primarily on the brightness of
the backlight and I ran out of patience before I'd got that dialed
in perfectly. It was far improved compared to scanning with
reflected light though.

For 35mm negatives and slides, I've also gone through the options
from the above rig, to a slow-but-good Epson Perfection V200
scanner, to a quick but rubbish SD card slide photographer thing.
As TNF suggests, photographing backlit negatives/slides with a DSLR
camera and a quality lens is probably the best option, though too
expensive for me. To some extent I've given up.

If you think 110 was horrible (and it was), towards
the end there was Kodak Disk Film - basically specks
of 8mm movie film stuck to a circular pinwheel card.
Movie film is bad to begin with - any smoothness comes
from the brain blending all those frames together.

Let's just say that the first digital cameras - often
VGA rez, sometimes a bit worse, where STILL better than
Disk Film :-)

Indeed they were.

My 35mm fuji film was around 3MPx but the grains didn't have square
edges...todays CCDs match or exceed half plate cameras let alone medium
format.

Friend took a photo of me 2000 with a digital cam from 1997. It used 3 1/2"
floppies to save (less than 8?) images. But the quality was pretty descent.

I still have a few medium-format cameras - Pentax 6x7,
Mamiya 645 Super .... also some 4x5 Graflex press cameras
and some big 4x5 studio camera and the body (but no good
lenses) for an 8x10 studio. Got a few pix from that one
using a borrowed lens - spectacular.

The fold-up "press cameras" are far more practical.

Somehow, despite modern sensor rez, the medium-format
film cameras still make for a "better" picture. It may
be like the tube-vs-transistor amplifier thing, tek-spex
ain't the whole of it. Tri-X with dilute HC110 in
medium and large format makes absolutely splendid pix.
Plus-X was good too, but you can't get it anymore. Hate
the T-grain films. I like the "tone" of Tri/Plus-X.
Same with the double-emulsion expanded-range Verichrome
Pan. I did get some fair results from B&W chromogenics
however.

Alas while you can get some spectacular digital backs
for 'Blads these days, they never made any for the P6x7
(maybe the later P67 though, I don't remember). I really
do like the "Giant SLR" design 6x7 however and have a
good selection of lenses. Makes a satisfying Ker-Thunk
sound as the focal-plane shutter cycles.

But if you want ultimate grainless diffaction-limited
perfection, try Technical Pan in 4x5 with a light
yellow filter at ASA-25 :-) You have to make yer own
Fake Technidol developer now though.

On the other extreme. I once found a $8.95 mini digital
keychain camera in a drugstore. I think it was like
147x95 rez - likely used an old CMOS memory chip as
the sensor. The pix were SO bad, with a weird spectral
response, that they actually had an artistic quality.
Lost the damned custom USB cable though ......

Oh well, chemical photography is Too Much Trouble
these days. WOULD like to try some of the antique
processes however - tintypes, ambrotypes etc.

Ambrotypes are interesting in that they actually
produce a negative - which is made to appear as a
positive by bonding it to a black background. The
darker emulsion also reflects more light, so it
appears whiter. There was also an early color pix
technique using dyed starch grains which acted as
point filters over a B&W emulsion. Polaroid sold
an "instant positive" 35mm film that used a similar
trick, but under a microscope you'd see parallel
colored lines. It was popular with police investigators
for a time. These were "autochrome" process and
the old plates had a wonderful slightly pastel
color rendering good for portraits and landscapes.

The weirdest photo I ever saw was done with a
24x24 wet plate, seeded with algae. Took a weeks
exposure. The more exposed the area the darker
the chlorophyll color. I suspect you can do the
same with living plant leaves. Acidic emulsion
on a zinc or copper plate might make for interesting
infrared photos - the heat accelerating the etching
in the more-exposed areas. Again a wet-plate process.
