Hello,

I've recently started using DeNoise and Sharpen and I'm wondering if there is a way in LRC when a batch completes to flag or identify the original file so I can sort by the old extension or unique indicator so I can easily sort/delete original files?

Thanks,
Jon

Why would you want to delete the original file? The Topaz derivative is fixed and hard coded If your original was a lossy JPEG, your Topaz derivative is an even lossier JPEG. The original JPEG was lossy compressed and data was lost. The file sent to Topaz was compressed and more data was lost. Topaz made changes and even more data was lost when it was compressed and saved. So the returning JPEG has lost data in three different episodes of lossy compression and expansion.

You should be shooting RAW where the original data is preserved losslessly. Any JPEG made from that will only incur 1st generation lossy compression. If you use a lossless file format like TIFF, you never suffer the effects of lossy compression.

If you shoot RAW, the file extension makes it easy to tell the original from any derivatives. If your Original is a JPEG, you can use an identifying keyword to note original JPEGs. You can create a collection of originals and never save a derivative to that collection.
