I have catalogued a number of files in LR but have not worked on them.

Sandman
Then you don't know. Stop talking about things you do not know anything about.

Eric Stevens
They clearly can't contain as much data or be reconstructed to form a final export image.

Sandman
Depends on whether or not you're exporting a full resolution image, Eric. Just as I said.

Eric Stevens
You are suggesting that files exported from LR are based on a degraded (i.e. downsized) version of the original file. I very much doubt that that is the case.

Sandman
I have suggested no such thing, Eric. You would know that if you knew how to read and comprehend English.

Eric Stevens
Once you look at the actual file sizes I think you will have to conclude that I am correct.

Sandman
Of course not, since you're not correct. As I said - every single image you work with in Lightroom has a 1:1 preview file created for it. Every single one. You can select when those 1:! files should expire and be purged, but if you've worked with it, or even vviewed it in the develop module there exists a 1:1 preview of the file.

You know nothing about these things, Eric, stop making claims about an application you don't use.
