p.1 #1 · Editing time in EXIF data

First...a confession...I'm a plonker.

With that out of the way...one of my cameras is still set an hour fast due to winter time in the UK (we muck about with the clocks twice a year) and I hardly ever use it, I've only noticed it now I've done a couple of weddings and tried to do renaming based on chronological order and it's thrown everything out.

So, in essence...can I select the serial number of the offending camera (30D FWIW) and add an hour onto the EXIF time stamp to all of them ?

Do you use lightroom? I found it pretty easy to do it that way when I was messed up with different times for my main and 2nd camera.

Or....try this:

I personally use ACDSee Pro 2.5 which allows me to move the time forward in a batch, so I select all the images from the camera that is out of sync and change them all by the same amount of time.

Cheers

Yes... you can do this in LR 2.0 in basically the same fashion.

Funny - I was looking for the same thing tonight. My cameras were 48 seconds apart since I used my camera to sync them. Wish Canon had the seconds as well as minutes.

SteveRock, downloaded Exiftool, but because I don't speak fluent computer programmer it's just not working for me, despite putting in exactly what it tells me to do, I just get "not found" messages.

Jonathan, downloaded the first one that came up on google (EXIFeditor) but it only seems to allow me to change the individual VALUE of the time, rather than adding an hour on to ALL images like I'm hoping to do.

Seriously tearing my hair out here, before I knew I could do it I was calm, just told myself I'm a prat and would have to work round it, now I know I can do it, I'm getting frustrated at the total gibberish the instructional notes are written in :S

Seriously, whoever solves this will get a pint, even if you live in deepest Timbuktoo, I WILL fly out there and buy you a drink.

Chris, if it's that frustrating, it must be worth the price of a copy of ACDSee Pro. You'll get the bonus of being able to do all sorts of things like matching exact copies RAW images even when one or the other has been renamed. You can even edit them (although I still use Bridge and Photoshop for that). Hell you can play your RAW files in a slideshow if you want including with music. Sort them and play them by an EXIF field if you like.

How much time have you wasted already? Go on, buy a copy.

Batch advance the time and then sort by that field and renumber them. Ecerything else can at least sort by filename.

Aperture - very useful for this.

Steve, I'll look into that, I'm just not so sure about spending money on something I've never used, but I guess if it's recommended here it'll probably do the job.

Steve, have downloaded the trial of ACDSee Pro, but whenever I edit the images, I've told it to bring the time forward by an hour, and bridge stubbornly refuses to accept the changes.......

Did you look at the user guide or search the help index Chris? I'll create and post an instruction for you as soon as I get home from my breakfast meeting this morning. It'll have to go up to flickr first as I am not a paid up uploader here.

No I just opened the GUI and did the "alter time stamp" thing, which seemed to contain the exact settings I needed, except for the fact that it didn't seem to actually alter anything :-S

Changing the time stamp in the exif through most (all?) software does not change the time stamp in the actual raw file. So, if you make the change in ACD and then open the files in another program the time will be unchanged.

Aperture amends the time stamp in the sidecar file and alters the way the file is presented within the aperture program - which has the intended effect if you are using Aperture to manage files.

ACD would handle things similarly - and based on your description of what is happening I suspect this is the phenom you are experiencing.

Bugger.

Guess my best bet is to run them batched and then amend the JPGs ?

OK... I'll help you out... download the free trial of LR 2.0 and get it all up and running. then while in Library mode... filter the metadata and select the camera you want to change. it will then sort out only the images taken with that camera, make sure you highlight all of the images you want to adjust. Scroll down on the right hand side in the metadata area and you'll see capture time, it will say "mixed". Select the little clipboard thingy to the right of mixed and it will open a window asking you how you want to edit capture time. You want to select "shift by set number of hours" all done.

Chris change your dialogue box to look like this and do it again. This works for me, but I'm not on a trial version.

Red is correct in what he says. So what I do is the changes to the time stamp and then sort in ACDSee, renumber and then re-order in filename order to process the RAW images. The resulting processed JPEGs have the amended time stamp in them.
