How to flatten image in DXO after NIK collection

DxO PhotoLab
1

After processing image in NIK Collection file size is 200 Mb. Before it was 35 Mb. Is it possible merge layers in DXO Photolab to downsize it.

dxo doesn’t do “layers”.
when you send a file to nik plugin from PL, it create a .tiff file and that’s what you working on from there, that’s the reason why your file is now 200mb.

I just processed a a 25MB raw file and exported it to the Nik Collections from PhotoLab and the end result was a 237MB Tiff file. Quite normal. Tiff files are very large. When I export the tiff to jpeg at 100% quality I end up with a 14MB jpeg.

I think it is a way. But I d’like to save image in TIFF. IN Photoshop you just merge layers and have original image size.
Nevertheless Thank you.

if there are no layers ( which you can check easily ) then surely you can compress TIFF ( w/ more or less quality loss - that can even include going to 8bit and lossy compression too if you are so bothered by 200mb … but then always a chance that whatever ends up in TIFF container will not be readable :laughing:)

PS: in PS raw is not the “original image” once you rasterize ( demosaick ) for your purpose

Two options seem to offer a chance for a smaller file.
First off, the (Version 6) Nik tools have a checkbox for non-destructive editing. According to the utilities, if you check this the file you save is going to be larger.
I unchecked it, and the resulting file was still 145Mb vs 34Mb for the RAW.
Second option: After the Nik work, return to PL and export the TIFF to disk as an 8bit file. Much, much smaller. Smaller than the RAW, but larger than a 95% quality JPEG.
