Title: Preview Problem
Post by: mdijb on September 15, 2017, 12:18:21 am
I send 2-3 image as layers onto Photoshop, create a focus stack, and reimport the flattened image into LR.  The preview of this image will not load to reveal the normal, sharp image.

This occurs 90% of the time.  Anyone have a fix?

so.... what are your intermediate file?  TIFFs, PSDs? 

Are you looking at the return file at 1:1?

PSD? And Photoshop's preferences are set not to maximise compatibility? That would mean a PSD with no preview available to LR.

Maximize compatability?->YES

The Raw files are sent to photoshop and a TIF file is returned to LR.

It is the 1;1 file that will not load in LR.  The small image appears normally.

Michael,

Which versions of Lightroom and PS are you running?

What workflow are you following?

- select 2-3 files in Lr and "edit in" "open in PS as layers"?

Using LR CC 2015

Photoshop CC 2017

Send 2 raw file to Photoshop as layers, merge the stack and flatten, return to LR as a tif file.

I'm using PS CC 2015.1.1 and LR CC 2015.12

I'm unable to replicate your problem.

What size is the Tiff you return to LR? I seem to remember LR has some size limits, i.e., for huge files LR will not display a preview, and/or will not even import them. I don't remember the specifics - pixel dimensions greater than 30K on one axis? or maybe just file size, a la Photoshop not saving .psd if it's say, 4GB?

Is there any chance you might have encountered something like this? (although I do remember that when LR choked when I tried to import giant .jpgs - for huge mural prints - it did show an error dialog about being unable to import them)

the Size of the iMAGE sent to LR is about 130MB.  A tiff File.

Attached is a screen shot of what I am seeing when I try to look at at a 1:1 image

Ihave updated to the current versions of LR and Photshop CC.  So if this is a bug, it has not been addressed by Adobe.
ANYONE ELSE have any suggestions??

Do you have ‘build 1:1 previews’ selected as the import option ?

Have you tried selecting the image then Menu>Library>Previews>Build 1:1 Previews (select “only one” from the dialogue box) ?

Does either of these fix it ?

Turning on "build 1:1 preview" seems to have fixed the issue.

thanks for the help[

Same image or different image ?

Have you tried rebuilding the 1:1 preview for the one image ?

Have you recently optimised your catalogue: File>Optimize Catalog ?

It is also possible that your preview cache is corrupted.  See here: Why and How to Clear Your Lightroom Cache (http://www.lightroomfanatic.com/tutorials/advanced/why-and-how-to-clear-your-lightroom-cache/) for instructions on how to do this.

I hope you get a resolution soon (pun not intended).
