My 2:3 fullframe images are not a perfect 2:3. So, if I set LR to output 900x600 images for wordpress, I get 900x599 or 899x600 images in most cases if the aspect ratio is left as "Original". If I change the aspect to "2x3", and then immediately export, I get the right size. However, when I return to the image, it is back to "Original" and if I make changes, I have to explicitly set the aspect to 2x3 again. Is there a way to get LR to be sticky on the explicit aspect ratio, even if it thinks this is the same as "Original" ?
