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.

I have seen this issue appear over the years with many EOS cameras when using EOS Utility. If you choose to only save the image to the computer, and not on the camera card, then there is no image number created by the camera, so the computer starts from 0001 each time. 

There is a workaround, since you can customise the filename that is saved by EOS Utility when you are only shooting to the computer or you shooting to card and computer.

I'm on a Mac so I have Mac screenshots, but the settings are the same in Windows. 

To customise the filename open the EOS Utility preferences...

When the preferences opens select File Name from the dropdown at the top. Then click on Customise. Screenshot 2024-07-25 at 16.05.14.jpg

EOS Utility allows three different custom filename settings to be created. I have selected the third one as I already had some configuration in the other two. From each of the drop downs you can select the data to make the filename, or simply type text in.

To create a unique filename, I will use the shooting month, shooting day, hyphen, shooting time, hyphen and then sequential number. This is to ensure that if you capture more than one image in the same second there's no duplicate filenames. You might not even need that sequential number if you capture pretty slowly.

Once you have made the setting, press OK and you will then need to select this customised setting as the one to use from the first filename screen. 

Deciding where to write files, camera or computer or both

With EOS Utility running you will see a screen like this one below. Click on the camera icon just below the ISO box.

This will display this screen where you can decide where to save images when shooting tethered. 

One feature I often use is to shoot RAW + small JPG for portrait shoots and send only the JPG to the computer as a quick preview for me and the subject. Small JPG is usually more resolution than the computer and transfers quickly.

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.
