P: Crop to specific pixel dimensions

Thanks! That's exactly what I was hoping to try today.

I hoping to avoid adding multiple photoshop steps for each image.

I have not, although I saw your video last night. My originals vary somewhat in size, but I plan to play with this and see if I can make it work.

Thanks!

Rose,

there is one trick that I found and I just tested and it allowed me to create an export at exactly 2697x1518. I just created a blank image of exactly those dimensions in Photoshop, loaded this into Lightroom, and synced just the crop to another image in Lightroom. Then exporting from this with long edge set at 2697 creates an image of exactly 2697x1518 pixels. This might be a solution for you.

I guess the only real-world option is: export from lightroom bigger than you need, crop in Photoshop. I know this is a dodgy and time-wasting workaround. I think you won't find a better solution. I gave up.

I've found threads with similar bugs as old as 3 years ago, and I'm not seeing a fix. 
When resizing in Lightroom, setting a custom crop too close to a default ratio, the crop snaps to the default. This seems to affect export, as exported images are 1 pixel off of the size set with dimensions.
If I choose 2697x1518, that's what I need.
The publishing page simply will not upload a file that is 2697x1517.

Have you tried the method I posted in my youtube video? Your required aspect ratio (if you indeed need 2697 x 1518) is pretty weird as it reduces by only 3 to 506:899. If the numbers go over 999 you can't enter it! The process may look long-winded, but if you repeatedly need the same size, you can pre-prepare an empty image with that crop ready to copy, and paste it on as many of your photos as you need to upload.

in order to sell my photos, the publisher requires images that are specific pixel dimensions. 
I crop based on art - if I don't think it looks good, I don't try to sell in that dimension.
But, If I'm perfectly happy with the art and appearance of 2697x1518 of my work, it is completely absurd that lightroom will only export 2697x1517!
Is that one pixel important artistically? perhaps.
But, not having it means my image simply will not upload to the publisher.

And, I do have photoshop. But, Lightroom was supposed to streamline the process of sorting and exporting photos for the photographer.

that would be swell - but it doesn't respect the custom ratio if it is 'too close' to a preset ratio
