Any ideas why one just one occasion (out of hundreds use) some images
'dissappear' from the memory card. I make a point of never deleting images
using the camera delete option (its only a extra keypress on a small screen
to delete ALL) , but some important images dissapeared between being shot,
(visible on the built-in screen) and presumably hitting the memory. That day
the camera was turned off and on many times, so it was reset frequently, and
yet images from five small shooting sessions dissappeared. I did try to use
image recovery software, but as I continued to use the camera, (and filled
the card) and evidence of the images went too.
I can't repeat this, and its only happened once, but it reduces confidence.
I have experienced on a couple of occassions, 'lock-up' where when switching
the camera on, it hasn't initialised correctly, and whilst the display is
then operational, its not possible to shoot images. Turn off, turn on again
and alls fine. I guess that may be 'heat' during summer outdoor use (which
incedentally is where nearly all photography takes place for me).
Has anyone experienced 'image loss' or 'lock up' , what's the cause, or is
it me.?

Perhaps you should ask this question in one of the digital forums.

It's Karma for posting digital issues on rec.photo.DARKROOM.

Well, if you've owned you digital equipment more than six weeks it's
obsolete anyway and should be replaced immediately. Sounds like some tired
electrons to me.

Seriously, post to a digital forum and give details on what memory card,
etc. you were using at the time.

Ask on rec.photo.digital. This forum is for darkroom work (developing film
and making prints photochemically).

I don't think it's heat. What I'd do next is:
(1) make sure never to turn the camera off while it's still writing on the
card, after taking a picture;
(2) format the memory card in the camera (something may be slightly amiss
with its formatting);
(3) make sure batteries are properly charged (erratic behavior will result
when batteries are weak).

Its probably you,. You may want to
Redirect the question to the rec digital newsgroup its more appropriate there.

Try using film. Latent images never disappear and
there's no storage card to go bad.

I was on a wilderness trip last summer with a bunch of college
students. Those who used digital cameras had endless troubles
with the devices and especially malfunctioning storage cards.
A whole week's worth of images was lost by one student due to
a storage card. The students using film had no problems and
took their images home.

But just try to argue with a digital geek about the stability
of storage cards...

Yeah, and none of us have ever put the fixer in the tank before the
developer or mis-processed our film any other way! And the Post Office has
never lost a roll sent out for processing. And the lab has never had a bad
day and no one has ever walked into the darkroom when the tech was loading
film and ...

It's a good idea to back yourself up when shooting any life critical images.
The price of digital is high but no higher than buying a second Hasselblad
or F-5 if shooting a once in a lifetime event. Or if charging for your
services. The way I sort the amateurs from the pros at events is look for
the guy with one VERY expensive camera--he's the amateur. The pro will have
several beat up crappy cameras and come home with the goods.

Well, not me, anyway... :-)

Had them lose a bank check once (for $6K) but never film.
Anyway I'd recommend fed ex over the USPS...

Suppose that depends on the quality of the lab and
employees (i.e., a sober employee is a competent one...)

Can't argue with that. Only caveat is I have lots of
images where the situation or lighting only allowed
for one exposure.

Reminds me of a couple of weeks ago I brought a few rolls of film to a local
camera store for processing. They have a mini-lab in the back and I wanted the
one hour processing. I came back two hours later and was told that they "lost"
my film.
