I always store derivatives of my master photos either in the same folder as the master photos--for Edit In PS PSDs/TIFs or in subfolders for Exported copies, so in my case I’d put them on ED1 and they’d get backed up to ED2.
The reason I do this is because at some point I might want to archive things and move them elsewhere off the ED1 or perhaps swap out an ED1 with an ED4 and the ED2 with an ED5, when things got full.
If my derivatives were separate from the master photos I’d have a hard time finding them to put them in the same archive as my originals and 10 years hence, I’d have even a harder time matching things up if I’d gone through several reorganizations of some sort. At least with things in the same or subfolders they’d be relatively “close” organizationally and easy to find or move en masse.
That makes a lot of sense, and now that you mention it, is rather obvious!
Do you use a laptop as well?? There may be some advantage to having the catalog off the iMac on a separate disk again if you use a laptop as well. One catalog works best and easiest for most situations.
Store derivative files with the originals and I would recommend using TIFFs rather than PSDs for maximum compatibility.
No, at this stage, the finances and the wife's forbearance extends only to the new computer and drives!
No laptop just yet but I do understand the comment on the one LR catalog and will bear that in mind.
Could you elaborate on the compatibility aspect re TIFFs?
Ok, the catalog will be fine on the iMac then. I have two computers and have my catalog and files on external drives and can just plug and play in either....
One catalog is really the best solution for most purposes.... I have had more than one and it can end up a mess easily. I also spend a lot of time sorting out messes for other people around the world and believe me it ain't pretty.
TIFF is an open format used widely, PSD while used fairly widely is an Adobe product and hence has less compatibility. I have this from people who know way more than me
Thanks for that.
