I used the Batch Change keystroke - I went thru the pics with my husband last night and could see every now and then some pictures were out of sync....I took most pics with 50D but every now and then, to record the GPS location I shot with my iPhone...for some reason those pics sometimes line up and sometimes just are plunked down.
I did create an album for the iPhone pics [imported them with that name] and adjusted the time to PT/Lisbon...still some are off kilter. The iPhone was on Lisbon time throughout once we got there. The 50D was on Iowa time [CDT/CST] throughout.
Thanks for the explanation = I may just have to do some edits one by one with the items I remember being shot at the same time...Not sure what else to do.
How did you try to correct the time, Victoria? Don't use "Metadata > Adjust date and time" (unless you already used it - then you need to revert that change), but use "Metadata > Batch change > Adjust Time Zone". The problem is, that when image files do not contain a Time Zone stamp, Aperture will by default use the current system time your mac is set to as the time zone of the images on import. Usually you will set the "Camera Time" and "Actual Time" in the Import panel, to tell Aperzur ethe correct time zones. Only that is not possible, if you are importing images taken in several time zones at the same time.
You cannot batch change all the time zones of all images at once, if the camera time zones differ - it is really a bit involved. I had similar problems with my camera and iPad, when we were travelling in Aslaska and Canada this summer and were frequently changing the Time Zones - sometimes two times a day. The iPad with automatic time zone setting was very problemitic, because I never could be sure of the time zone on the iPad - if there was no Wi-F,i it would use Canadian Time on Alaska ictures and vica versa.
- Separate your photos into albums with images that you are sure have been taken with the same camera (iPhone, Canon) and with the same time zone setting in the camera.
- Then, e.g., select the album with all photos taken on the iPhone, with the Time Zone set on the iPhone to "Portugal" and use Metadata > Batch change > Adjust Time Zone" with the setting "Camera Time is Portugal" (since your camera was set to Portugal, when the photos have been taken)
To prevent this kind of problem, I always keep all camera times set to UTC. This way I always exactly know the time the camera was set set, when I import the image and do not have to remember to change the time when travelling. Only, that is not feasable with iPhone and iPad. If you want to use your iPhone as a clock and not only as a camera, it is impractical to have it set to UTC.
