EOS 90D file numbering while tethering

[Wattophoto]

I recently bought a 90D body specifically for dslr scanning of negatives, slides and prints. I'm really happy with the quality and using the EOS Utility 3 for shooting live on my Macbook Pro.

One thing is bugging me, though, and that is the numbering returns to 0001 every time I turn the camera back on. 

I read in the manual, checked online and watched some video tutorials, but they all only talk about file numbering when shooting to card. I know I can set File Numbering to "Continuous" to ensure the number doesn't reset every time the card is changed, but it doesn't help when shooting tethered.

I have large archive jobs to scan, and want to be able to have the file numbers continuous, even if shooting on different days.

Is there some way, either on the camera or in the software, that I can make sure the numbers are continuous when shooting tehtered?

Thanks.

Watto.

Thanks Brian. It looks fiddly to set up but might be the way forward. At least having the date and a sequential number will be enough to solve my problem. I'll give it a go this week and report back. Cheers, Craig (Watto).

Thanks Brian. This is about the best option and is working well. Cheers, Watto.

Go to the menu's and to the wrench icon #1. You'll see File Numbering Tap and go to Manual Reset.
