What to do with JPG & RAW files

Ok, I see several members have missed the point of your inquiry,

How long to keep JPEG files that were crested in tandem with RAW files, in camera, or if to just keep them.

Treat the JPEG as a limited copy of the RAW file. Treat the RAW file as your original negative. Do not loose the RAW file. If you are done with providing a copy's of the JPEG to clients, your call if to trash. Once you have post processed the RAW files you can quickly export to JPEG files if needed. At that point those in camera JPEG files will no longer match your post processing decisions.

One  consideration for photographers that publish to news sources, etc, do you need to keep on hand the original media provided to the client? And does the client consider the JPEG initially shared as that original, or are JPEG files treated as not original as a JPEG is by default manipulated and the RAW is the original despite what was previously shared. This point is not completely logical as the people making those decisions ate often full of it.

I hope that you keep backups of your photos. One consideration is to include those JPEG files in the backup and delete them from the working folder (if you are looking to save space in the working folder)

Not a pro, so take with a grain of salt. Maybe this reply will get those with more actual experience to respond. If other members state I am full of it, good, they would then be on point.

Lightroom has two options. It will either treat the jpeg files as sidecar files, meaning you won't see them in the catalog and you cannot delete them separatley from the raw files. Or it will treat them as separate images, so you can select the jpegs and delete them if you want to. That is a setting in Preferences - General.

After a quick search I found some info on the software that should have came with your camera called 'Digital Photo Professional'.  I think if you open a canon raw file with it you will be able to export a jpeg that mimics sooc jpegs.  Make sure to verify this functionality before changing your workflow.

Although I adopted a raw file only + Lightroom workflow long ago, it was nice knowing I could export a sooc jpeg if I wanted to.  The Nikon version also shows where the focus point was so I've checked that a few times here and there.

So you import both the jpegs and raws into Lightroom?  Do you edit jpegs as well as raws in Lightroom?

At what point in your sorting workflow do you decide if you need to go deep on editing?

I don't know about Canon, but with Nikons NX editing software that comes with the camera it is possible to produce a jpeg similar to SOOC from just the raw file.  I haven't used the software in the last 5 years though.  I wonder if Canon has something similar?
