Question

Adobe CC - 'Copy' the crop settings do not 'paste' as expected!

Those of us who have dreamed of an option to input numerical values for cropping images in Adobe Lightroom CC (having moved from Lightroom Classic), we have somehow managed to find ways around it. I thought selecting the 'Crop' option for my 'Edit Copy Settings' would work, however I have noticed that something unusual is happening, that I just cannot workout, and I'm not able to get the exact crop I want when exporting an image.

Let me clarify what I am trying to do, and maybe it will make my issue clearer.

I export portrait headshots regurlarly, and I need them to be very specific ratios/crops. I find a photo on my hard drive that I've already exported at (for example) 485x462px. I then find this photo inside my Library, and 'copy' the crop info. I paste it onto another photo, and export that photo. During exporting, I use the option for 'Long side' to be 485px. I would expect the output of the photo to be 485x462px, but nope, it comes out at 485x453px. This is suggesting that the crop I'm pasting is just not the ratio of the one I am copying from. In fact, I visually see this is the case, as when I paste, it seems to be in a portrait not landscape setup (although yes, it's almost a square).

 

Has anyone else found this to be an issue? Perhaps when it copies the Crop, it uses some kind of algorithm about the size/ratio of the 'uncropped' image (which does vary at times) and makes adjustments in respect of that. Who knows. But this is driving me nuts. 

 

Thanks for help in advance.

When you crop specifying only the long side, Lightroom will ensure that the long side of the image will be the specified number of pixels. However, the short side will be relative to the number of pixels in the image. In other words, if the short side of the image isn't the exact number of pixels as the previous image that you cropped then it is unlikely that the short side of a new crop using the same long side specification will be exactly the same. If you need an image with both the long side and the short side with exactly the number of pixels then you need to specify both sets of numbers. But Lightroom could only produce an image that is 485x462 pixels if the short side is long enough to produce that.

Thanks for the reply JimHess. In all my images there is way more image than I need. So I appreciate if there is not enough image, then yes, the 'short side' will not match what I want. However, let me just separate 2 terms I'm using here, which are Crop and Export.

 

The only time I can instruct the program to match a certain number of pixels, is during the export process. The actual 'crop' part of the workflow, really is more about the aspect ratio of the crop. So I'm copying the crop from one image (that I can only assume is the correct aspect ratio, as the 'exported' version is the correct H&W in pixels), and pasting it onto another image in Lightroom. When I export that image, again, instructing the image to match the 'long side', the short side seems to vary and is never the same every time. 

 

I'm questioning where and why this variation is evident.
