Show both original and adjusted JPEG in a single folder

Create a new version from the orignal

(following up on Frank's response) ... and if you want to preserve the adjustments except for the crop, duplicate the Version and then press "c" to change the crop adjustment.

It's not _entirely_ clear what you mean, though, because you seem to be using "JPG" to refer to adjusted Images in Aperture.

Its a manual thing. There are no settings to set up a particular project or album that way.

If you want an unedited version along side the edited one you need to make two versions, one you leave alone (it will be the original) and the second one you edit.

Note, too -- in case you don't know -- that typing "m" will toggle any Image between the current state of the Image and the Image based solely on the imported file.

It's also on the menu at "View ▹ Show Original Image".

But using the M key won;'t show them together, you'll only see one or the other.

I have a need to be able to see the cropped/adjusted JPEG file along with the original master

and this

actually need to know how to show both the original and the adjusted file side by side
