Preventing live injest card injest duplicates

[bwana]

How do I get PM to recognise that the images on my card are the same ones the ones already live injested and not import them, again?

EDIT: to confirm Incremental Ingest: copy new photos only is already ticked/checked

Thanks - I should have mentioned that is already ticked. I've edited the OP.

I use a different folder for Live Ingest and after ingesting the card I simple copy the content of live ingest folder into the folder of the card.

And PM then picks up the duplicates?

The problem for me arises when I've shot 3-4k and have to wait for them to all injest, essentially for a second time, before I can get to the ones that I shot without being tethered.

Did your time zone change since you took the already ingested photos?  If so, that's likely the problem.  When PM scans for files, the file system will report a different modification time for the files after the time zone/daylight savings time changes.

No, same time zone. I often have to injest from the card immediately after live ingestation ends from the same location.

Did daylight savings time affect you?

No.

If I skip the live injest tethering PM ignores the duplicates.

Incremental ingest requires that a file be created on the source disk and the local computer. These two files allow Photo Mechanic to know that a specific file was copied from a specific memory card during a previous ingest, and that it shouldn't Ingest it again. When you transfer images to the Live Ingest source folder, Photo Mechanic has no idea where they came from: they're essentially just files that arbitrarily appear in the source folder.

Do you use the "Protect" function in your camera? Perhaps you could lock the images before you transfer via your tethering setup (or even have it just transfer those images as soon as you protect them? Not sure if cameras let you do that) and then when you go to Ingest the card later, simply only Ingest the unlocked files.

PM really can't tell that one file is identical to another file?

Unfortunately I don't have the time to transfer one image at a time, everything would grind to a halt.

No, it doesn't currently do that, I would absolutely have let you know if it did.

However, as a result of this thread, we've discussed a bit how we could improve this process for workflows that utilize tethering to transmit the images initially and then go on to Ingest the memory card later to avoid duplicates. So hopefully we will have something for you on this in a future build of Photo Mechanic.

Many thanks for the positive feedback.
