Thanks for the replies.<br>
<br>
You will find an example image here:<br>
<a href="https://drive.google.com/open?id=1GaokEvrZ3MEkIco_WmGHUXORZ4p30sQc" rel="noreferrer" target="_blank">https://drive.google.com/open?<wbr>id=1GaokEvrZ3MEkIco_WmGHUXORZ4<wbr>p30sQc</a><br>
This example is a little complicated so, forgive me if my explanation is a<br>
bit confusing.<br>
<br>
This tar.gz file has a few files in it. First, you will find the .cr2 file.<br>
Of course, that is the original file I shot with my 7D. Next, there is<br>
"IMG_7109-Edit-2.tif". This file was the file that I performed noise<br>
reduction on with Topaz Denoise. It's also one of three total .tiff files<br>
that I've had in my Lightroom library for some time. The other two .tif<br>
files I created for post processing experimentation. However, I have not<br>
tried editing those files in some time. As such, I decided not to upload<br>
those two files. However, I thought it prudent to mention these additional<br>
files, because I do believe the changes made to those additional files are<br>
tracked in the .xmp file that is shown here.<br>
Additionally, I've included two other files. The first file in that last is<br>
"IMG_7109-Edit-2 DNG-TEST3.dng". That was a .dng that I recently exported,<br>
to see how previews and edits .dngs. Previewing this .dng shows the edits,<br>
even after I've selected the "Preview shows the full image" option in the<br>
configuration widget. However, when I open this image in the image editor,<br>
the changes shown in preview disappear.<br>
Finally, "IMG_7109-Edit-2 TIFF-Test.tif" is also included. The previewed<br>
image and that shown in the image editor are both the same; both images show<br>
the postprocessing changes I've made in Lightroom 4.4. Of course, this is<br>
different from the other files located in the linked tar.gz file above.<br>
<br>
I'm guessing that the process for importing changes made in Lightroom 4.4<br>
would require me to create a second, .tif, copy of all files edited in<br>
lightroom. Doing so would allow me to preserve the post processing I've<br>
done while also saving the .cr2 that has the unmodified raw data. I wanted<br>
to run this by you just to see if there is a better way to migrate. While I<br>
do have enough storage space to keep multiple lossless copies of these<br>
original images, I'd prefer to be a bit more efficient with the space that I<br>
use.<br>
<br>
Thanks for the help and please let me know if I should provide anything else<br>
(including another example).<br>
