lightroom import dng unexpected changed the width and height of picture

[huangh12728086]

when I import an dng ,  I noticed that the size of dng has been changed for about 10~20 pixels.

I compared the size of dng in lightroom and result from python read dng.  the dng size is 10~20 pixels smaller.

for example,  a dng dimention shown in lightroom is 2048x3072,   when we use rawpy（a python lib） to read the dng, we find the dimentions is 2056x3088.

we want to know how the dng was cliped in lightroom ,  and can we recover the origin dng size.

Hi Huangh,

Sorry that Lightroom is unexpectedly clipping the image dimensions.

Which version of Lightroom are you using?

Are you working with DNG or Raw files from any of the Canon 5D Mark III, the Fujifilm X-E1, and some Olympus cameras in Photoshop Lightroom?

Please take a look at this article Images unexpectedly cropped in Lightroom and let us know if that helps?

Thanks,

Akash

we find the reason.  there are crop info parameters in DNG ,  and lightroom clip dng with this info. thank you.

Thanks for the heads up.

Glad to know you were able to get to the root cause of the issue.
