Lighroon Cropping Advice . Options?

[digitaldog]

I crop for image content and aspect ratio, not number of pixels in any one direction. 

Me too. We must be oddballs <g>.

Ahh yes I see that now (I don't really do crops of that magnitude).

Can you wait to do the crop in ACR?  ie do your LR processing, maybe even with a rough crop in LR, then open as a smart object in PS and then use ACR where you can re-adjust your crop.  ACR does not have those limitations.  You can change the % size and the fit works (to fit the crop not the whole image).

Hopefully those attributes will make their way to LR some day.

there are external options of course but for those projects where I dont plan  on using photoshop ideally it would be useful if the preveiws for tiny crops could be increased in size proportionate to the cropping

Everyone does.
The issue is that cropping, unlike exporting, changes the relative size of the subject in the final image and usually the aspect ratio.
If you are doing product work for a customer and you are doing similar work successive times you need to crop the latest images the same amount and same vertical location as the images you did last month or the product this month will appear on the website at a different relative size to last months and the table will be at a different height.

So all products are cropped from full size to the same size and required aspect ratio and then you just move the crop left or right to centre it.

If your ‘similar size’ images, month to month, are identical as to distance, focal length, position, product size, etc I can see how you could use the same image size and vertical location.  While this may be your situation , I doubt it is a very common situation for many…or even for you.  That being the case, In Lightroom, you could also just copy the crop from a prior image and paste it to this months images. 

Aspect ratio consistency is easy…just select common one (or define your own).  Then crop and position.  Once sized, easy to copy to subsequent images on batch….and move around

That is exactly the case. Same lens, same distance, same camera stand height. The products are bags so there are bags the size of suit cases down to handbags, wallets and belts. So I need a number of defined sizes.
Yes, there are always work arounds, but why not just display the values? It is easy enough that every other application can do it.

LR clearly isn't for you; time to move on. You need to let it goooooooo.

LOL. 20000 posts, nearly three a day, 7 on this page, sometimes immediately after your own. You should go out more.

[digitaldog]

Users can and do specify pixel size of a crop on almost every other programme. It is a basic requirement.

Do tell the tens (if not hundreds of millions) of Apple users of both Photos and Preview more of your incorrect generalizations!
Almost; nice try Bob.

Yours is a one off case relative to most people’s usage, so I do not see LR committing effort on it…particularly as there are workarounds.

You have now expanded your need to a ‘number of defined sizes’, which I assume you have to determine and document for future use.  I suggest you set up (define) a set of images in a folder with each of your crop cases.  You can then go the the defined image you want, copy the crop (ctr-c, chech ‘crop’ only), paste to images you wish (in batch if you wish).

And unlike yours sir, factual.
I'm sorry if I offended you with my experience, expertise, and common sense.

Absolutely and easily doable in Lightroom Classic. I have one client who's images I shoot, every month I do this upon. Hint: listen to John if you can't figure this out.

 is the image  im attempting to crop ....appear at the size of a mathcbook on screen........on a 21 inch screen  its simply a PIA to crop it  uslng  lightroom alone.

the option to increase the size of the preveiw...when cropping... is missing in the version of lightroom i use

BTW, the first picture I put up was from the Preview app and shows pixel sizes and it is also easily done on Photos using the Raw Power extension.

Does not change the facts (without an extension) that dismiss your silly generalization!

Maybe you'll someday figure out how to crop in LR like John and I.

The Preview app, the most basic of editing programmes,  does not require anything to view the crop pixel size. That is the way it works. Just look up.
It even does it on raw files, but you have to save as a Tif.

Yes, it can be done with a workaround in Lightroom Classic of having to go back to something you did before, but why do we need to use workarounds. It obviously knows the pixel size, why not display it?
Why defend an obvious lack of a feature in a product that keeps on charging when free programmes can do it.

No one is defending anything.  What you want is not in LR and probably will never be there.  You have been shown an easy to use alternative (actually easier and more accurate than pulling out a box to specific xy pixel dimensions).  It is your choice to use the alternative offer, find another for yourself, or use the other programs you find do what you want.

BTW…as Andrew showed you in earlier post, the ‘Info Overlay’ has an option for ‘cropped Dimensions’.  As you crop the image, release the mouse button and it will show you the current size.  Addition x or y movement will get you close to the size you want.  Not as exact as copy/paste, but probably within about q0 pixels depending on resolution of screen and mouse/tablet

Well what he said was "Specific pixels don't exist until the raw is rendered (on export). " which is neither correct or what I am asking.
Exporting is not cropping.
Copying from another image you have to go back and find is OK. Being able to drag to a size and see that size is great. Being able to actually enter a size digitally and get that size is even better.
There are programmes that do that.

Let’s not get into ‘bashing’ mode.

What he said was

This the ONLY data Lightroom Classic knows about pixels from the raw, as shown: based on the crop.
IF you export the full size raw, (you do not alter as shown in the resize options within Export), that's exactly how many pixels you get.
Anything else pixel wise, not from the full resolution raw however isn't shown, can't be shown, can't be known until it is defined at export.

Possibly, not exactly clear to you, but, frankly, you were not really clear on what you wanted…at least to me. 😀

So basically…you’ve got what yer gonna get.  Digital entry….probably never….very limited need, in my opinion.
