Using Adobe Camera RAW to Enlarge Cropped RAW Files

I shoot a lot of wildlife, and as such I've learned that you can only get so close, and more times than not you're going to need to crop your image to get your subject. For digital image sharing that's usually not a problem since sharing is usually done at 1000-1600px on the long side, and with 16MP and more on the original image even radical crops are OK. But, if you're shooting with the goal of printing your images at something larger than 4x6 or 5x7 then a radical crop can leave you with an image that will need to be upsized should your edit prove something you want to print, and in my experience any enlargement at that point leaves you with pixelated edges and other things you need to deal with. I ran into this when I attempted to take an edit I did 2 years ago of a Snowy Owl and print it as an 8x10 (my wife wanted an 11x14) - the original edit took the 4928x3264 D7000 image and cropped it to 978x1223, which is barely a 3x5. Everything I tried produced a decent at best 8x10 if you viewed it from 4 feet away, but at close inspection it wasn't clean.

I pinged my brother for help and he told me to send him the image and he should be able to clean it up. I asked him what his trick was and he said, "I just use Adobe Camera RAW. It's better than any tool out there at interpreting up-sizing." He explained how to do it and I told him I'd give it a shot. While it definitely worked better, it led me to go back to the RAW image and start from scratch to see if enlarging prior to editing would allow me to make an even better image. Sure enough, it did. Upsizing a radical crop before editing allows you work with an image that is either as large or larger than what you'll eventually print, so you can clean up what you need to clean up, and then resize down to 8x10 or 11x14, which is always easier when preserving details.

The following video explains how to do it. It should be noted, I left out a step where he recommended that you set the ACR sharpening to 0 before opening the image. It would see that the ACR function used to perform this enlargement is only available in the direct ACR interface. So, while Lightroom is essentially a fancy ACR engine, I've yet to find how to perform this enlarging step prior to sending the image to Photoshop. If I find it I will update this thread, and if anyone knows how to do it, please post a screenshot of where the setting is, because I've been looking.

This has me seriously rethinking my RAW editing workflow, which is Lightroom for basic adjustments and cropping and then off to Photoshop. Now I'm thinking that while I'll still use Lightroom for catalog management and basic edits, for photos that require some level of radical cropping (less than 50% of the photo) I may switch to this method, opening the RAW file directly in ACR and then sending it to Photoshop. When I'm done, I will import the resulting PSD file back into LR (a step that would have been automatic with the old work flow). The edit of the RAW file now also exists in a sidecar (XMP) file, and the next time I open Lightroom it will pick up the XMP file and update the preview to match what I did in ACR.

If you want to merge the XMP data into the LR catalog permanently, first remove the image from the catalog (hit Delete and then choose Remove - do not delete the underlying image!!), then use the Import function to bring the RAW file back into the catalog. The thing to note is that the re-imported preview will be back to the same size that you would have gotten from doing the edit in Lightroom in the first place. The resizing is done on the export from ACR to Photoshop.

Interesting post, thanks. Not that I'm very happy with you! I've been getting lazy and rather comfortable with my workflow. I used to use a Adobe Camera RAW and Photoshop a lot.. now I'm lazy and just use LightRoom.. your post just reminded me of this! :)

I hear you. I wouldn't call it lazy, because Lightroom edits are just reorganized ACR edits, but if you've abandoned PS entirely then ... well ... truthfully only you know if you should have done work in PS or if the LR edits were enough. You can do an awful lot in LR, and really don't need PS for most editing. But this is the first ACR function I've found that I can't replicate in Lightroom. Hopefully someone will tell me differently.

And I should add, when my brother shoots RAW he says that no matter what he does in ACR, cropped or otherwise, he just resized to 24MP's automatically before editing. With the image I used in the video I decided to take a shot and upsize a cropped D7000 image to D800 size (36MP), and the truth is I could have easily used it as a starting point for my editing. I would never consider doing that level of resizing for all my D600 and D7100 shots now, but I'm just glad that I haven't dived head first in to my Yosemite Park re-editing project, where I have a bunch of D7000 and D90 images that deserve a second edit with 3 more years' experience under my belt. I may actually be able to print that 16x20 landscape over the fireplace now. LOL

Jake, Great Tip, Thanks.

Questions, you mentioned Perfect Re-size and I was wondering if this is basically the same results or did you find doing it this way is better.

I tried Perfect Resize and for what I was trying to do it just didn't do as well. Truth is, as I look at the 8x10's I printed from the files I used Perfect Resize for they're really not that bad, though there was no way I could have gone 11x14.

I did figure out how to do this from Lightroom. Video to follow shortly.

OK, folks, I figured out how to do this from Lightroom. It was under my nose all along, but I just couldn't bring myself to remember that there are other ways to alter the size of an exported file when using the Export function. The gist is that you need to the adjusted RAW file as a TIFF or PSD file, upsizing by setting the number of MP's in the Image Sizing box. It will even import the new file directly to your catalog, so it saves a step or two!!

I don't have to change my workflow!!!!

He shot Nikon back in the day when they had the original Kodak digital backs. He said he'd still be shooting them if the pro support was as good as Canon's, and regrets selling all his old AI glass now that the DF is out.

I have just tried this. Thanks.

I also did it a different way as well. I did my cropping on my 12 MP file, (D300) then I did my usual editing. I then exported the image in JPEG upscaled to 12MPs.
Is this makes a difference if I want to send it off for a 11x14 print, or should I have saved the image in TIFF?

Up-res first, then crop.

Though I'd posit that "up-res first" requires you to know how much you're going to want to crop to preserve the level of resolution you want on the final image. In other words, if I know I'm going to crop, and I know I'm going to want a 24MP image post-crop, it's likely going to take me several attempts to up-res the image first before getting the desired result. Crop in LR or ACR and you get precisely what you're looking for.

But thanks for your in-depth, reasoned account of just why you should do it your way.

My post pertains to considerations prior to editing. There are certainly methodologies on how to perform upscaling post-edit, but that's not what I'm addressing here. My point being that handling any artifacts from the upscaling is likely more convenient at the start of the editing process than it is at the end.

That said, when you are upscaling on an export it shouldn't matter if you are exporting to a jpeg or a tiff, assuming that no other manipulation will be done post-export. If you are going to have to apply corrections then I would export as a TIFF, open and edit that at size, and then save off as a final JPEG to save space.

I answered while I was stuck in traffic and forgot to explain myself when I got home. Yes, my method requires that you figure out how much you are going to crop first, undo it, uprez, then reapply the crop. I only mention this method because the uprez routines require data and the more data you give them, the better the job they can do. Granted, if you are only going to use a square inch of an iPhone selfie, there is not much hope for you.

Fair enough. Agreed about having as much information as possible, which is why I tend to crop in a little more than I need, but not so much that I start with a 100MP+ file, which is what would have been the case in my original file. On my Mac with 16GB of RAM I can still get the CPU fan humming, so I can only imagine what it would do with lesser computers. I would think that data far outside the crop would have little impact on what's done within the cropped area, but perhaps not? Good food for thought. I guess it would be possible to run tests on different types of shots to see under what circumstances it makes a marked difference. Like, are you better off when the stuff you're cropping out is similar to what you're leaving in, or when it's varied but detailed enough to assist in resolving all the details? Don't know enough about the details of the algorithms to even venture a guess.
