Quote: If it didn't, you would lose that original file you started with, which LR and Aperture are sworn not to do
And, even with what you said, I'm still not 100% on the
why the process is setup like this.
why would i lose the original file?
Consider this:
Aperture and lightroom both swear to non-destructive work flows. Ok - so if I take my RAW file, I can do whatever I want to it,
within that application, exposure adjustment, white balance, cropping, whatever. The original file will stay in tact but you still see the changes.
The changes are simply instructions telling aperture/lightroom hey - take this raw file, and do x,y,z to it then display the result. No additional jpeg or TIFF is created in order to do this.
In apertures case, these instructions produce a result it calls a version.
So, why is it that, when you use a plug-in, the result of that plug in is not considered a version i.e. simply instructions for the program to do to the raw image, rather than creating an entirely new TIFF or JPEG?
take raw - do steps x,y,z - display - step z for example would be the things done in the plug-in.
...hmm...actually that might be the answer - if step z is the instructions from the plug-in, the plug in would either have to be reopened anytime the image was to be viewed to make the changes or the instruction set would have to be sent back to aperture...which i would guess is proprietary; if it wasn't then aperture would just be able to do the job i asked the plug in to-do.
ok..
on a related note my RAW images are 10mb in size (6MP), but when I put that file into photoshop or any other plugin for apterture, the resulting TIFF is anywhere between 17MB to 30MB depending on cropping. Why would the result, which if anything I would assume is destroying data, take up more that twice the original space?
