First of all, thanks for the inputs.Probably because JPEG is a compressed picture/file format, there is much more black in your HHHR un-cropped so much more room for compression.
Now I am just guessing, so if I am wrong someone here will be sure to correct me!
The Tiff file before exporting into JPG is 299MB and 121mb for HHHR and non-HHHR, respectively. I exported both the same way. I don't think a bit more black would make that big of the differences.
One thing I didn't mentioned in this thread is that I use Mac Photo to do final editing of the image and for the exporting into JPG. it is just the old habit
Unless I use Oly Workspace to do initial PP, I can never export the JPG using Tiff file from DxO with my Mac Photos. In essence, earlier I tried to use DxO to convert raw file into Tiff then use my Mac to do final touch up and exporting. The image is too soft and I couldn't never really export the JPG without weird artifacts.
Now, by producing OW Tiff, follow by DxO PP into another Tiff for final editing with my Mac Photos, that issue resolves except this small file mystery.
Anyhow, I am not going to loose my sleep as 3mb is plenty big enough for me and it retains better image quality than that 7mb non-HHHR JPG.
