Lightroom: Book Module 'Export to JPEG' does not apply sharpening

I'm running LR4.1 on Windows 7 64 bit with 5D MK ii raw images and just discovered the Book module 'Export Book to JPEG' produces files that do not have output sharpening applied.

Example Book Settings:

Book = JPEG

Size = Standard Landscape

Cover = Hardcover Image Wrap

JPEG Quality = 90

File Resolution = 300 ppi

Sharpening = (Every setting produces the same results)

Media Type = (Every setting produces the same results)

When selecting 'Book = PDF' the sharpening is very obvious and is applied as expected based on the Sharpening setting:

Glossy Low = least sharpening

Matte High = most sharpening

The ‘Export Book to JPEG’ should have output sharpening applied the same as ‘Export Book to PDF.

Oh, so sad. I was just about to applaud Adobe for allowing JPEG output. It would have been better if book module had custom page sizes too, but for a start, I would be happy with having JPEG output. However, if I cannot have trust that sharpening (and possibly other settings?) are properly applied, it's next to useless..

Looks like I have to have even longer before Lightroom reaches the stage where I bother to purchase it.....

Well at least Adobe has changed status of this problem to 'Acknowledged. Hopefully a fix for both this issue and addition of custom page sizes are being investigated.

"Looks like I have to have even longer before Lightroom reaches the stage where I bother to purchase it....."

I use InDesign CS6 with the Blurb plugin, and only checked the Book module JPEG output to compare the image sharpening used in it. Personally I have very few issues with LR4 and love PV2012, but there's a similar sharpening/resample issue in the Slideshow module that's been around since v1.0. Maybe Adobe will finally fix both of them.

I just checked the Book module Export and noticed less sharpening is being applied to the JPEG image. Clearly it is now applying some sharpening to the JPEG, but the PDF output still does not match.

I created a one-page book with black background and Exported to PDF and JPEG with the following settings:



I then opened both the JPEG and PDF images using PS CS6 and less sharpening is being applied to the JPEG image. They should be identical.

I rechecked the Book module Export to JPEG sharpening using LR4.3 Final Release. The JPEG export images still have less sharpening than the Export to PDF images.

I also compared the Book module Export to JPEG image to the standard LR Export module (Export One File) output using the same settings and image sizes. The Book module JPEG has much less sharpening applied.
