1^st Post

Came across a weird effect last week.

A pro photographer sent me some images for use in a publication, for a mutual client.

All the mages had been taken on the same day and copyright encrypted. It was a Canon image...which may or may not be relevant.

When I came to use them one image crashed my system. In fact it corrupted the whole publication rendering it unopenable.

Needless to say I tried various tricks, involving resaving, tweaking in Photoshop. Every time it crashed my publishing programme. In fact, I used the file in two different publications using two different software packages....it corrupted them both.

(I won't mention the swear words required to rebuild the publication from TOO old backups!)

On examination the file had TOMORROWS date in the exif.
The other 4 images had YESTERDAYS date. A two day difference despite being shot at the same time?

I cunningly put aside the work for a couple of days...in the belief that the encrypted date would be safely passed and useable by then.

Wrong....the b*gger corrupted the files again. (fortunately newer backups prevented more reconstruction work)

So I am left thinking that a more significant corruption had been embedded and the wrong date was just a symptom.

The strange thing is, it opened ok in photoshop ...it was only when I placed it elsewhere, the problem came out.

o.O

Sorry guys ...wasn't sure which section to post this.

Eric, Have you tried adjusting the date in the EXIF using something like EXIFUtils.
It could be that someone has put this in as a copy protection mechanism.
I guess that the file is too big to share but anyway I am out for the next few days so couldnt do any work on it until Monday.

Don't think it was deliberate The other images of the same machine, taken on the same day with the correct date, are fine.

I found a way round it....didn't use the image. Lol

Gone to press now ....so not bothered. Just wondered if anyone had encountered similar.

I have encountered similar effects but only if the image is corrupt in some way.

It opened ok and looked ok....apart from the fact it was a cr*p shooting angle and composition he had chosen. Lol

It was a relief NOT to use it.

:lol:
