Auto date on to phone photo?
 

I have a Samsung / Android smartphone.

Is there any app to automatically & permantely burn the Date/Time on
to the photo, like in the old film days?

If you're taking JPGs the date is probably already there.
Open a photo in IrfanView and check the image properties
to find out if there's EXIF data. But there's no such thing
as permanent. EXIF data is just optional data added to a
JPG header. Personally I usually strip it out for privacy if
I do any editing and/or use an image online.

You could theoretically use a system to embed data in
pixels, but even then it would be lost if the image were
opened and resaved. The image is just a bitmap that's
compressed. In other words, it contains a grid of pixel
color values. That's all there is in a raster image. The
rest is expendable and depends on the image format as
well as software.

Thanks, I mean just for family snaps. Even after adjusting in PShop
etc I still have to manually insert the date along with annotations.

Why? Your family only have to click see properties of the photo to know
when it was taken. No need to damage a photo by printing on top of it a
text with the date.

You don't have to "buy" this function.

Cameras insert EXIF data automatically as
part of shooting photos.

https://i.postimg.cc/9QCMPvhW/sample-exif-data.gif

"Date Picture Taken:" === EXIF data, inside the picture (4CC code...)

"Date Modified" === File Explorer info, when pic loaded from cam
(will be some time after the previous field)

Transferring hidden metadata to the surface
of the photo (which is an "image damaging step")
is a separate process. And less critical than
first ascertaining that the photos you are
taking, have the EXIF in the first place.

And as we've noted in previous questions
on the topic, Windows Search is indexing the
EXIF on your pictures too. It's just
a matter of finding the supported list of
EXIF fields, to search against them.
Not all of the EXIF fields in a photo are
indexed (although they should be).

datetaken:10/1/2014

EXIF could be removed, as a result of editing
with various tools. For example, if I used
NETPBM, transferred jpg == ppm == jpg, then
I would expect to lose the EXIF data.

So if you need "datetaken" to be transferred
to the front surface of the picture, that has
to be done with a non-naive tool. You can't have
junk tooling in the workflow, or there could be
loss of stuff like that.

That's also the reason, that incoming materials
should be archived, and kept separate from all
of the steps that come after it.

There are other devices that don't
use EXIF. A cheap webcam isn't going to stamp
like that. VLC screenshots wouldn't have it.
GIMP screenshots wouldn't have it. But digital
cameras are usually pretty good at placing
that info in EXIF.

*******

So now is the fun part. What fun would it be
to use a dedicated stamper program, when you
can whip up some commands for your own self ? :-)

If you are using an Olympus camera the date is in the file name.


PB251249

P an identifier
B the month of the year November ( 1 2 3 4 5 6 7 8 9 A B C )
25 the day of the month
1249 sequential number.

To keep track of the year, I have a folder for each month of the year
where I store pictures take during that month.

Other cameras have the date with a different numbering scheme.

But all have the date on each photo metadata, together with other data
such as camera model and settings. A mobile phone will also record the
location.

My photo negative scanner does. The pain is that it sets the date to
"Fri Jan 1, 2010" and can not be adjusted (in pre-process).

Does this imply your photo negative scanner has
a CR2032 in it ? A battery ?

That value is not an accident, it's a "hint" that
maintenance is required.

Google the model number of your scanner, and see
if there is either:

1) A software app to set the time.
2) A battery replacement procedure.

There is no clock, as far as I know, the timestamp is fixed for all
photos. In fact, other another app says the time is " : : : : ".
And yet another app shows the hour fluctuating, but always the same day.

This is interesting. How can the hour change if there is no clock?
Something else setting an arbitrary time?

There is a rechargeable battery in place, but I do not remember reading
about any clock setting procedure in the papers.

It is a reflecta x7-scan.

https://reflecta.de/dynamic/dlFile/a83e72851b8dd95f9e25d6fd2fdbf91a/user-manual-x7-Scan-english.pdf

I don't see anything about setting up the time, which is a real
nuisance, because forces me to use other tools to set up the date - the
date when the photo was taken, not when scanned.

https://www.firstcall-photographic.c...-scanner/p5346

Size: 143 x 106 x 108 mm
Weight: 1kg
Compatible: PC / Mac (as Mass Storage Device, no driver required)

So it doesn't seem to have a flexible interface
from the USB cable at least.

It has the electronics of a digital camera, but
lacks an interface. You would think the LCD screen
and buttons would give access to internal functions.
The manual shows all the icons it's got... and
no time function.

Try the huji app. it even also adds colour artefacts of old style
disposable cameras.

nuisance, because forces me to use other tools to set up the date - the
date when the photo was taken, not when scanned.

I have a similar 'scanner' [1], a Rollei DF-S 290 HD. It has the same
behaviour, with the difference that mine sets the (EXIF) 'Date taken'
((Windows) File Explorer property [2]) to "1-1-2018 12:00". During use,
the time part changes, i.e. 12:01, 12:02, etc..

So I'm afraid that this is just bad behaviour and nothing you can do
about it.

FWIW, my scanner sets the 'Program name' field ((Windows) File
Explorer property) to "COACHWare 1.0". Maybe your scanner uses the same
firmware.

N.B. I do no longer use this scanner because it gives crappy/
unreliable results, i.e. (very) low quality pictures. I now use a
flatbed scanner with negative/slide capability, a Canon CanoScan 9000F
MarkII. That (Canon) scanner leaves the (EXIF) 'Date taken' field empty,
which IMO is better, i.e. better an empty field than a wrong field.

[1] It's not a scanner, because it does not scan. It takes a picture (of
the negative/slide), so it's essentially a digital camera.

[2] In (Windows) File Explorer, right-click on the file - Properties -
'Details' tab - Origin - Date taken.
