Lightroom: 4.4RC: 32 bpc tif file rendering broken - far too dark - far too ugly colors

Hi,

I just installed LR 4.4 RC.

When I look at my finished/already developed 32 bpc tif files, they are all far too dark and have an ugly color rendering. This is true for the previews, in the develop module as well as for exported files.

This is how a crop looks like in LR 4.4RC:

And this is how an exported image crop looks like in LR 4.3:

https://dl.dropbox.com/u/23843309/cro...

This means: I cannot work with my 32 bpc tif files in LR 4.4RC.

Please fix this asap.

Thanks.

Best regards,

Manfred

PS: In the meantime I feel a bit tired of working with 32bpc tif files in LR 4.3/4.4. Too many serious bugs....

Hi,

>Can you please send us the original raw file with its xmp, so we can verify?

What do you mean by original raw files and xmp? The Canon .cr2 files?

The issue was with a 32 bpc tif file, merged from 5 cr2 files, not with raw files.

Unfortunately, for copyright / IP reasons I cannot forward the cr2 files as well as the complete 32bpc tif file.

What do you suggest instead of forwarding these files?

I am pretty sure that you can easily test the wrong rendering in your environment. Take 5 raw files, merge them to 32 bit, and work in LR 4.3 for some minutes. Then upgrade to LR 4.4 RC and it will render strange.

Thanks.

Best regards,

Manfred Schneider

Hi,

in the meantime I can now provide a 32bpc tif file rendering correctly in LR43 and bad in LR44RC

https://dl.dropbox.com/u/23843309/32b...

I created this file in 5 minutes: merged 5 canon cr2 files with Photomatix Merge to 32 bit, then imported it in LR43, edited it 2 minutes in LR43, closed LR43, installed LR44RC in a VMware Workstation 32 bit WIN8 system, imported the 32bpc file in LR44RC and ... it renders incorrectly.

So it is very easy to test this behaviour in your environment.

Best regards, Manfred

What version of Photomatix? Out of curiosity, do you have a copy of Photoshop? Curious if the Merge To HDR from Photoshop produces the same problem as files merged in Photomatix.

Hi Jeffrey,

I used this this for merging the files: Photomatix Merge to 32-bit HDR Plug-in for Lightroom 1.02 (Merge32HDRsoft102x64.exe)

I just merged using PS CS6. Here is the file

https://dl.dropbox.com/u/23843309/32b...

When importing in LR44RC it seems to render fine :-)

Some days back I posted another issue "Photoshop CS6 'Profile Mismatch' warning on PhotoMatix files with same profile name (but wrong profile content)" ( see http://feedback.photoshop.com/photosh... ). The Photomatix plugin embeds a wrong profile / a wrong gamma.

But in LR43 these photmatix files (with the wrong gamma) are rendering fine. Now in LR44RC the rendering is wrong - without any change from my side.

Therefore I would expect that my files are rendered the same in LR43 as well as LR44. And I cannot go back for all my files and merge them in PS CS6.

BTW: the reason why I have choosen Photomatix to merge the files is: PS Merge to HDR Pro often shows colors casts in the 32 bpc file. Photomatix does NOT show such color casts.

Thanks.

Best regards

Manfred
