P: Lens Corrections defaults not correct if Previews are "Embedded & Sidecar"

Todd,

So you agree this looks like a bug? I'm new here, do I need to do anything so Adobe is make aware of this?

Thanks,
Nicholas

No, Lightroom will not automatically build standard previews. It will only do that when I tell it to. The images come in with Embedded previews, and this stays that way until I click on the double-arrow icon in the upper left corner to tell it to build standard-sized previews. Or they will be built when Lightroom is idle (if you set that in the preferences). Maybe I won't see the issue you are discussing, but please don't think you can tell me how my own workflow works.

"I have to admit that this could be because I also apply a develop preset on import."
That's not the same type of Import we are discussing here. If you apply a 'Develop Preset' in the Import module LR will automatically build standard previews. This also negates the speed benefit of using 'Embedded & Side car' previews and will prevent you from seeing the issue discussed here.
To duplicate this issue you will need to:
1) Change your 'Default Develop settings with 'Enable Profile Corrections' checked.

2) Import with NO Develop Setting selected in the Import module and 'Embedded & Sidecar' Preview selection.
Once the import has completed confirm you can see the double-arrow icon on the filmstrip in the upper left-hand corner of the thumbnail. Then switch to the Develop module without applying any settings and view the Lens profile panel. What do you see?

Yes, I always import with 'Embedded & Sidecar' to speed up import. After the images have been imported I let Lightroom generate its own previews. Lens corrections and chromatic aberration are then applied automatically and correctly.

I have to admit that this could be because I also apply a develop preset on import.

Johan, did you actually try this for yourself and Import raw files with the File Handling> Build Previews setting 'Embedded & Sidecar' selected? Please see my post below and tell us your results using this Import setting and your 'Default Develop Settings' with 'Enable Profile Corrections' checked.

I can confirm what you are seeing using LR 7.5 on Windows 7 with Canon 5D MKII and 6D cameras with 17-40mm F4L and 16-35mm F4L IS lenses. With 'Embedded & Sidecar' Import Preview setting the Lens Corrections panel appears as below and has the error message 'Unable to load lens profile.' Interestingly when I switch back to the Library module the image displays with the Lens Profile and other 'Default Develop Settings' applied and is no longer using the Embedded Preview. This is without applying ANY setting in the Develop module.

So it appears there are two issues. It's my understanding that when using Embedded & Sidecar Import Preview setting the Library Preview will not be updated until Develop module settings have been applied. Merely viewing the image in the Develop module without applying any adjustment settings should not cause LR to discard the Embeded & Sidecar Preview and rebuild a new preview.

The only way I am able to "repeatably" get the Lens Profile to be applied in the Develop module is to click on the Reset button (applies my default settings) or Sync the Lens Profile setting across images.

I assume that's because 'Embedded & Sidecar' means that the preview you are looking at is the embedded preview that the camera added to the raw file. Lightroom's lens corrections are obviously not applied to that preview. Only when Lightroom has created its own preview, the lens corrections are applied and visible.
