P: Allow Crop Settings in Presets

Patrick, your use case makes perfect sense and is simple: Make the preset behave just as if you had used Copy/Paste Settings or Sync.  That's a simple behavior that non-advanced users can understand, and which I think Adobe should implement.

(My Any Crop plugin, targeted to advanced users, addresses many different use cases, including exact-pixel crops, but at the expense of a much more complicated user interface.)

It would look like this...

Saving my "develop settings" as a preset is what I was trying to do and found it it wasn't possible.  Seemed strange since I could save the develop setting.

I have a Canon 5Ds 50mp full frame camera. I have a Sigma 10-20 lens designed for a crop camera. When placed on my 5Ds at 10mm the outside is highly vignetted. If I remember to set the crop aspect ratio to 1:1.6 before I shoot, LR imports the file and crops it automatically to the proper area in the center of the image that is truly 10mm wide (the whole vignetted image is actually there). I end up with a 20mp image taken from the center in the 3:2 ratio.  I just want to save that center crop for when I don't set it in the camera first. Seems to me the only time such a crop preset makes sense is to crop the FULL size image down to the preset values (exact pixel count and ratio). But others might think differently. I can use Autosync in the develop module where crop is applied to all I have selected, so I have a relatively easy work around. I was just surprised that I could SAVE the exact crop settings in develop, but can make that SAVE that as a preset.

"This would be very useful when creating the same aspect ratio on other pictures that I want to display as a series."

Very much agreed that displaying the custom aspect ratio as you adjust the crop could be helpful. 

The closest you can come with built-in features is to do add Cropped Dimensions to View > Loupe Info using View > View Options.  This shows the cropped pixel dimensions, which can be entered as Custom crop dimensions in the Crop tool.  Unfortunately, the Cropped Dimensions are only updated after you close the Crop tool, which seems like a strange oversight.

Also, you can copy your custom crop from the first photo to the other photos in the series using Settings > Copy/Paste Settings.

Yes, and while we are all holding are collective breaths waiting for Adobe to provide a simple solution to an easy-to-address problem, could I also request an on-screen aspect ratio indicator. Sometimes I will crop a picture to specific content and arrive at an unusual aspect ratio, e.g. 1.97:1. This would be very useful when creating the same aspect ratio on other pictures that I want to display as a series.

There is no reason why preset settings and copy paste settings should be different.
There is not 1 engineer at adobe who thinks that this should be useful? just turn it on please.

Another voice, calling in the void for this feature. I can define a "user crop preset" in Photoshop; please let me also do it in Lightroom. Why are the two panels (shown above) different?

In the "Crop & Straighten Panel", we should be able to apply specific dimensions or percentages as well as aspect ratios. 

Come on Adobe, don't be afraid to answer your users. We are actually on your side. We want to let everyone know how cool our product of choice really is.

After 7 years this request  is always not implemented? is it so complicated?

"I need to use the predefined cropping parameter of the development module to automate cropping at import (as is possible with the "copy / paste" see attached picture).Is it possible to implement this parameter
