In the Affinity Photo Workbook exercise "Peak Country  1: Mam Tor" (page 138), the exported JPEG is not as sharp as the adjusted TIFF image before export. All settings were followed carefully. I don't see this type of loss when exporting a TIFF from DxO Photo Lab 2 to LIghtroom 6, then exporting a JPEG from LR. Thoughts? Suggestions?

Thanks for that Gerry, if you change the Resample dropdown from Bilinear to Lanczos 3 Separable then you will find the exported JPEG slightly sharper than when using Bilinear. I hope this helps!

I had to recreate the exercise to get a screen grab of the Export settings. The original JPEG file earlier today was 26.1 MB. This one is 19.2 MB

As far as I know, I followed the Workbook faithfully. 

For the file size test, instead of recreating the exercise, maybe try this instead:

1. Open the mam_tor.afphoto file (not the tiff) from the unzipped mam_tor download
2. Open the Snapshots panel, select the "05. Finishing Touches" snapshot, & click the "New Document from Snapshot" button:
421271371_snapshotpanelsetting.jpg.d5abfd2bfca7ac7822abd2e93b07fef1.jpg
3. Now, export this new document using the settings on page 151. You should get a file size very nearly the same as shown in the export dialog on that page.

Some of the other exercises mention snapshot resources like this exercise does at the top of page 150. When you see them, they always refer to an .afphoto file included in the download. They can be handy for comparing your work to the author's, & for things like this.

Thanks. I'll give that a try.
