• Welcome to the Lightroom Queen Forums! We're a friendly bunch, so please feel free to register and join in the conversation. If you're not familiar with forums, you'll find step by step instructions on how to post your first thread under Help at the bottom of the page. You're also welcome to download our free Lightroom Quick Start eBooks and explore our other FAQ resources.
  • Are you ever disappointed with your photos? Do you get frustrated when you’re editing because you’ve been told to move certain sliders, but never been told WHY? Do you wish you could transform your photos without having to spend hours in front of the computer? In my new book, Adobe Lightroom CC - Edit Like a Pro, you’ll learn:
    • how to to analyze a photo like a pro, saving you hours of frustration.
    • WHY you might want to move specific sliders, instead of just following recipes.
    • what the sliders are doing behind the scenes.
    • how to use sliders together, instead of in isolation, so you can get the optimal result
    The book is based on the cloud-native Lightroom CC desktop and mobile apps, but the principles also apply to Lightroom 6 and Lightroom Classic. The sliders are arranged into slightly different panels, but there's an included PDF that shows you where to find them in Lightroom Classic/6.
  • It's Lightroom update time again! No new features in the mid-April release, but new cameras, lens profiles and bug fixes. Here's the usual list

Cropping by fixed pixel not ratio.

I want to crop every photo to the exact same pixel dimensions. Lets say I want 4410 x 2835 so the ratio is 1.555 : 1 and I can enter that in the Crop tool as a custom ratio. Lightroom of course does this but I can't seem to get it to limit the size to the desired dimensions. It keeps the ratio right but the dimensions are not locked. That same ratio gives me 4410 x 2835 or 5048 x 3246 or 1113 x 716 etc. Ratio is right but the resulting crop size is highly variable. How can I set the crop tool to provide a 4410 x 2835 block that I can position? Thanks

You'll have to use Photoshop for that. Lightroom won't do it. A few people have been asking for the ability for ages.

That said, you can, by trial and error, create a crop of that size and then paste it onto other images. Setting a line of your View Options to "Cropped Dimensions" will help. It's a poor workaround, but it will work.

Thanks guys, I'll try Hal's work around or just Photoshop. It's a shame they don't give this option in Lightroom.

It will only work on images that have the same pixels dimensions as the one used to create the crop ratio. Change cameras and you still get the crop ratio but to fit the maximum dimensions od the pixels presented

I just have a burst of the bird singing, D 850 Raw files. So everything but his beak is in same position. I wanted to do identical crops as easily as possible.

Hal's copy settings suggestion will work if it is the same camera. Unless your camera were mounted on a tripod and there was no wind blowing the lines, you could overlap the bird with only the beak in different positions .

I've never manage to get the same crop in the same position of the frame since I was always hand holding the camera and there is other movement li the limb the bird is on moves with the wind.

Take all the shots uncropped, and edit-in-photoshop as layers. Use the Align Layers and it will come pretty darn close to making everything line up. Then crop the whole image (all layers at once).

Where you go from there depends on what you want. You can build an animated gif, or you could create separate images from each layer and they will be identical in size and alignment.

None of this is in LR of course, you'll need to save-as the result and import back into LR (well, not if you did a GIF, it won't support them).

I'm not near a Lightroom computer but what I'd try - set your crop to the ratio you need, save, and check your resolution. Usually we choose Length x Width x 72 to get a precise file size.

Not what I'm trying to do, again thanks everyone. My question has been answered to a suitable degree. No further responses are required.
