The *only* point Lightroom loads the original file and applies the rendering chain in RAM is when you're viewing an image in 100% zoom.
Or when you export the image.
Depends on how you export it. If you export it as a low-res highly compressed JPG, it can use the preview file. Chances are that it doesn't, but it certainly could, since the preview file *is* the current pixel data of the image.
So what happens when you want a high quality TIFF of the same size as the original file? Do you expand by resampling your low-res highly compressed JPG?
questions like this mean you don't understand how it works.it *always* uses the original data. the cached previews are a speed optimization for the user interface.Eric Stevens
I know that
No, you don't.Eric StevensSandman
but Sandman seems to disagree.
With what, you're ignorant question born from your ignorance about the application? Well, yes.Eric StevensEric StevensSandman
That's why I asked him that particular question.
No, you asked it because you have no clue how LR works.
I don't know why you don't bother writing my posts for me: you seem to know *exactly* what I really meant. :-(
