Question

Cropping on Import

  • March 3, 2024

Just got a Leica Q2 and noticed that photos imported into Lightroom Classic, latest version, are cropped inspite of having "None" in the boxes Apply During Import.

Files in Fast Raw Viewer are 8392 x 5632 giving 47.26 megapixels which is the advertised size of the sensor but in Lightroom Classic and I would add Photolab the size is 8368 x 5632 giving 46.72 megapixels.

I assume that this is the lens correction but would like confirmation from someone more knowledgeable than I.

This happens with my OM Systems cameras as well although with them although the pixel sizes are reduced 5220 x 3912 in Raw Viewer compared in Lightroom 5184 x 3888 the image in both has the same visual edges whereas the Leica image shows a very definate crop.

Don't understand  this at all

Any help would be greatfully appreciated

    This is very likely due to the built in lens correction which unfortunately for this camera cannot be turned off (why Adobe why?). I downloaded a few raw samples from this camera from dpreview and indeed you have automatic lens correction that cannot be turned off. Adobe automatically applies lens corrections for all mirrorless cameras but only for recently released cameras allows you to turn off the corrections. My Nikon mirrorless is one of those where you can't turn off the correction while the v2 version of the same camera (which gives identical raw files) they allow you to turn correction off. There is a hack that you can do by removing the lens profile from the raw files that fixes this but that is a destructive process. I do this for astrophotography images where I don't want the built in vignette correction as it causes banding in the images.

    You got me looking since I shoot with an Oympus E-PM1 and you said "This happens with my OM Systems cameras as well  ...". Then there was @Jao vdL comment of "Adobe automatically applies lens corrections for all mirrorless cameras but only for recently released cameras allows you to turn off the corrections. I was concerned I was missing some pixels. Here is what I found:

     

    • The same image in LrC and OM Workspace are reported the same size 4032x3024.
    • In LrC, Develop->Lens Correction, there is a note. See below. I can still enable/disable 'Enable Profile' and 'Remove Chomatic but it does seem to have any effect. I feel this is a change. In previous versions of LrC I couldn't toggle them. Seems to relate to what @Jao vdL was talking about.
    • In OM Workspace, I select Lens-> 'Distortion Correction', then the image does change with a slight cropping. The properties window still shows 4032x3024. If I export it to TIFF, it shows the cropped image with the original dimensions of 4032x3024. I mention this because I'm wondering the accuracy of some of dimensions we are looking at.

     

    So, I don't feel I have a problem but some of this may help with what you are experiencing and what @Jao vdL discussed.

     

    Here's the note from Develop->Lens Correction.

    I decided to install Fast Raw Viewer. I disabled it using LrC RAW Converter.


    When I look at the files I was using on OM Workspace:

    • ORF = 4056x3040
    • TIFF = 4032x3024 (same as what the ORF showed in LrC and OM Workspace)

     

    So the question is, is there an issue with Fast Raw Viewer?

     

    I then looked into the ORF  EXIF metadata and it shows the size as 4080x3040; more confusion. When I look at the MAKER metadata (Olympus proprietary) it lists the 'crop' size as 4032x3024.

     

    Sorry if this confuses things but I think what LrC and OM Workspace say are more accurae than Fast Raw Viewer.

    • Which version (actual number) of LrC are you using?
    • Which OS and version?
    • In Library, in Navigator, have you selected FIT and 100%
    • If your OS File Explorer/Finder, what is the information of dimensions and size

    Thanks
