Lens Correction and Cropped Pixels

I'm starting out as an architectural photographer, and as I don't yet have a perspective correcting lens to adjust images in-camera, I need to use the Lens Correction tools in Photoshop and ACR. I prefer to use them over the Free Transform tool for the sake of accuracy (and convenience), but I do have an issue with the tools. When I correct the perspective of an image and then process, whatever extends beyond the boundary of the canvas winds up being automatically deleted, and it seems as if there's no setting to prevent this from happening. As there is sometimes a piece of a photo that I would like to be able to retain (i.e. extra sky, the top of a building, etc.), I understand that I can scale down the image in the Lens Correction tool and then re-crop after processing. Of course then this causes the image to still be smaller than I would like it to be (in certain cases where the distortion correction is more extreme, an original 21MP photo might become a 12 or 13MP photo after processing in the Lens Correction due to scale-down).
Is there any way that the Lens Correction tool will allow for pixels extending beyond the boundaries of the canvas to remain uncropped, thus allowing me to expand the canvas in order to reclaim the extra information?

Yammer P, yes the list is shorter because it's a jpeg rather than raw, and we have more profiles for raw than for jpeg.
For the set of lenses supported in CS5's initial release, we created profiles for both raw and jpeg. Since then, we have been concentrating on raw-based lens profiles, for a number of reasons (one of which is that we feel we can consistently deliver the highest quality results this way). This is why you see some lenses supported with raw & jpeg profiles, but many more supported with raw only.
CS5's Lens Correction plug-in does indeed let you choose raw-based lens profiles even though it is processing a rendered file (e.g., jpeg, tiff). This will work in many (but not all) cases for distortion correction, but will often work poorly for chromatic aberration and vignette correction. I don't recommend this workflow and it is a key reason we don't let users mix/match in ACR & LR.

Lens correction and chromatic fringe - broken in CS5 ?

Hello, chromatic aberration correction has changed since CS3.
It's limited to ONE pixel correction, or what ? It seems i cant get strong cyan/red bands anymore, i used it as an artistic effect and i need it back. Any way to have it behave like before? I'm not interested in manual workflow (moving manually RGB channels), thanks.
Paolo

It definitely seems different between cs3 and cs5.
I don't believe there is a way to get the same effect in cs5's Filter>Lens Correction and it's
not broken just improved i guess.
You might try a pixel bender filter called Convergence (ships with pixel bender plugin) or Color Separation Effect

You would need to install the pixel bender plugin into photoshop cs5 from the bottom left of this page to use the above filters:

When making adjustments with lens correction, the crop isnt contrained to the image

When I first installed CC I was able to rotate, or adjust the image in lens correction and it would automatically crop to the available image dimensions.
But I deselected the contrain to image section in crop mode, and since then it hasnt work, even though contrain to image in crop tool has since been re-selected, many times.
Any idea whats wrong?

Thanks! All of my shots for this current interior shoot are panoramic. At a halt until I can resolve this.

Lens corrections and adjustment brush bug

First of all, congratulations for a spectacular implementation of these seemingly "conflicting" (at least in a non-destructive workflow) features.
Here, I got a fish-eye image where I want to paint the sky (say I want to make it darker). For the beginning, I just define the borderline between the earth and the sky.
Apply a lens correction and you get this:
Fantastic! The brush stroke got distorted almost perfectly. "Almost", because if you make a single brush click, painting a circle, it doesn't get distorted with lens corrections, turning into an ellipse (though the spot removal circles do). Instead all brush path point coordinates get recalculated along with the radius of the brush at each particular location. This works very well in real world even for extreme examples like de-fisheyeing. For rectilinear lenses, the difference is imperceptible.
And now, some bugs/limitations.
If you use a large brush, say I want to fill the whole sky in this example, things get a little more complicated.
Turn on lens corrections and...
The thick stroke gets distorted in a way that fill almost the entire image. This happens on extreme debarreling only. For normal lenses, it's a non-issue.
Also, sometimes I get a strange artifact in preview only. The exported image doesn't have this solid rectangle:
And a final, smaller, issue: for strong corrections like de-fisheye-ing, the brush pin easily gets lost outside the image area after you apply lens corrections.

While we do the best we can mapping the local corrections, it is not perfect if you adjust the lens corrections after applying them, as you can see in some of your extreme examples.
In the future, when processing new images, if you apply the lens corrections first, and then the local corrections, you completely avoid these remapping issues.

Lens correction and DNG

I have upgraded from Ltroom 3 to 5.2 and lots of differences straight away.
I have a question if
1) enable profile corrections
2) setup is Auto or Custom Or Default
3) the camera is correcr ( canon)
4) Model of the lens is correct EF17-40
5) Profile is shown as EOS-1D Mk 3
the arrows do not show any other camera and Mine is a Canon 50D, How do get the correct Profile to register also unable to update DNG files.
what is going wrong??

LR does not ship with a separate profile for each body, against each lens. The camera model info here, AFAICT just notifies you what camera the lens was mounted on, when the profile was created.
The same profile can quite happily work for other camera models too - even so far as, automatically extracting just the relevant middle coverage out of a FF lens profile, to correct images taken from a crop sensor body with the same lens mounted. (This will of course not work the other way around).
The profile's aim is to characterise the lens optical performance, which does not per se change when you move it between cameras - (although this may not be quite 100% precise, e.g. in terms of vignetting off microlenses etc, it is normally quite good enough IMO). In the past, profiles used to address CA as well, and I believe this issue was more sensor dependent (the newer LR CA correction does not depend on the profile).
If the need is a critical one, then your individual lens copy and your individual camera body can be used to "close the loop", and generate an empirically "perfect" custom profile. It's not very hard to print out and photograph the special targets, and then run the free DNG Profile utility; you can put as much or as little effort as you like into the number of focal lengths and apertures that you include. But if the supplied standard profile is good enough to save you that trouble altogether, it may not matter that it is not the theoretical best.
AFAICT, the installed / downloaded profile is likely more subject to LENS sample variation (between your lens, and the one used to make the profile) - than, anything to do with using a different camera model.

Do the lens corrections consider cropped sensors?

I tried using the supplied lens corrections for my Canon 70-200 2.8 with pictures from a 1DIIN (1.3X crop factor). I'm getting far too much corner vignetting correction by default and more distortion correction than necessary. Are the corrections defined only for full-frame cameras?

Actually I remove two data sets, which for f/1.4 and f/2.0, both are in same distance.
Note that, the original profile was created with 2 different distances.
So, I leave another distance set for correction module for interpolation.
And the problem found on the photo which around f/2.0.
But how the profile was generate, it may be my fault,
since I use too high shutter speed with my room fluorescent, the light source.
The flicker of the light may lead the optimazer to confusing.
I also observe that the distance reading from metadata record by the camera, with Lightroom,
was not corelate with the distance shown in the generated profile.
I'm not sure what the measurement unit, the profile used, but it should be meter.
For example:
I shooting at around 2 meters away from the chart, which close to the number in metadata.
But the FocusDistance in the profile is 11 meter.

Lens Correction and JPEGs

Hi,
I'm new to LR. I've spent the last two months watching every tutorial, practicing with a portfolio/video instructional off the Adode site and reorganizing my own photos and folders on my computer.
I finally took the "bold" step to put a few of my photos into LR. All my photos are from either a Nikon 3000 or 3100 with the same lens AF-S DX Nikkor 18-135mm f/3.5-5.6G ED.
Also, all my photos are JPEGs.
1) In Lens Correction > Profile > Enable Profile Correction there are 3 options
Default (no make/model options)
Auto (no make/model options)
Custom > when I click this I get the model and Adobe profile for the Nikon AF-S Nikkor 14-24mm f/2.8G ED
Is the Adobe profile the same for both lenses? The 14-24 and the lens on my camera - the 18-135?
Default and Auto look the exact same. If I click Custom, the image becomes a little more exposed. To my eye, Default/Auto look better.
2) Also, should I "check" chromatic aberration for all my photos? I'm not sure how this feature works in LR with JPEGs.
3) Considering where I am and my skills at this point, what is the best recommendation going forward, for learning LR and working with my JPEGs.
Since I'm going to be essentially working only with JPEGS for a while, what lens correction should I use with these photos? Default/Auto/Custom?
4) Are there any other settings that I need to pay attention to with the camera/lens/file type that I am using while trying to learn LR?
I'm starting to realize from my readings, that JPEGS will have a more limited range of development in LR and "LR will display only the profiles available for the file type of the selected image." Lens profile support | Lightroom 5, 4, 3 | Photoshop CS6, CS5 | Camera Raw 8, 7, 6
I want to become a more serious amateur and enthusiastic photographer, but I also don't want to spend 15 minutes editing/developing every semi-decent photo I take.
As an aside, my 3100 has a shutter problem, so I will be upgrading at some point (probably Micro 4/3) and I plan to explore shooting RAW or a combination of RAW/JPEG somewhere down the road.
Thanks
Andrew

As I understand lens correction profiles, most are written for RAW photos only, and there are only a few profiles written for JPGs. That would explain why you don't see your specific lens under Custom.
2) Also, should I "check" chromatic aberration for all my photos? I'm not sure how this feature works in LR with JPEGs.
I'm certainly not the biggest expert on chromatic aberration, but it seems to me that the chromatic aberration algorithms are looking for certain types of coloration at "edges", and I don't see why that would be different for JPGs compared to RAWs.
But I'm confused by the actual question ... checking the box and seeing if it makes the photo better seems so simple that I don't really understand why you had to ask the question.
3) Considering where I am and my skills at this point, what is the best recommendation going forward, for learning LR and working with my JPEGs.
Since I'm going to be essentially working only with JPEGS for a while, what lens correction should I use with these photos? Default/Auto/Custom?
Again, the learning process in Lightroom is ... just do it. You can't harm your photos, you can always undo whatever you did that you didn't like. The lens correction you choose is the one that makes the photo's appearance look best to you.
4) Are there any other settings that I need to pay attention to with the camera/lens/file type that I am using while trying to learn LR?
Any setting and any slider and any tool might be the right one for your photo. There is no general setting that EVERYONE uses, as the reason software provides options is that some people want it one way, and other people want it a different way.
I want to become a more serious amateur and enthusiastic photographer, but I also don't want to spend 15 minutes editing/developing every semi-decent photo I take.
The learning curve can be difficult, but as I said, editing your photos will never harm your originals, and you can always undo whatever you did. So ... just do it.
I am concerned that even as a beginner, you think it might take you 15 minutes to edit a single photo. Unless you are doing a HUMONGUS amount of brushing, this should never take 15 minutes, even for a beginner. Yes, of course if you want everything to be absolutely PERFECT, then it will take longer, but there really is no such thing as a PERFECT photo. Your goal ought to be (in my opinion) making the photos look GOOD, and learning what the sliders and tools do as you go. And certainly there is no unique determination of what a GOOD photo is, a photo that looks GOOD to you may not look good to someone else, but that's kind of irrelevant, its your photo, it should only matter that it looks GOOD to you.
You said you watched tutorials, are these tutorials helping, or not? Do you feel you have learned the basic purpose of (some of) the develop sliders and develop tools, or not?

Micro Four Thirds lens correction and Lightroom

Obviously LR seems to use some of the lens correction information it gets from Micro Four Thirds cameras. This shows when compared to results from RAW converters that don't.
I have noticed this for my Olympus OM-D and the 12-50 mm zoom. Is that the reason why there is no lens profile for that lens in Lightroom? And is this the case for all MFT lenses?

Aperture 3, lens corrections and Micro 4/3rds?

Does anyone know if Aperture 3 supports the lens corrections that are part of the Micro 4/3rds spec? Presumably this is what was holding up support from being added but can anyone confirm or deny whether they actually do support it now?

I see that Aperture 3 supports the RAW format from Panasonic Micro Four Thirds cameras like the GH1 but does not support the Olympus Pen cameras like the EP-1, EP-2, EP-3. Unfortunately I own the EP-1 and have been waiting since July 2009 for an update. Since it's not in Aperture 3 I must assume that they will never support Olympus Pen cameras. Adobe's Lightroom 3 DOES support Olympus RAW and you can download a beta. I won't be moving to Aperture 3 until Olympus RAW support is there. I won't be moving to Aperture 3 at all if Adobe beats them with Lightroom 3.
WAKE UP, Apple! Either support it or let us Olympus owners that you won't.

Camera RAW Lens Correction and Chromatic Aboration

Looking in the Camera RAW Lens Correction table I can't find a profile for my lens - Nikon AF VR NIKKOR 80-400mm 1:4.5-5.6D. The nearest in the table is Nikon AF-S VR Zoom-NIKKOR 200-400mm f4G IF-ED. Is this near enough or is there any manual data I can enter.
When shooting at f5.7 400mm 1/800sec ISO3200 with my D3S it is showing some Chromatic Aboration can this be corrected by entering data manually? and what are the figures I should use?
Kind regards,
Alan

The first thing you should do is update photoshop cs6 by going to Help>Updates from within photoshop cs6.
I don't know if camera raw 7.4 has a profile for that lens or not, so you might have to install the 8.1 beta i linked to in post #2.

Lens correction and Develop defaults

in this video http://tv.adobe.com/watch/the-complete-picture-with-julieanne-kost/enhancing-light/ J. Kost shows how to create default settings in the Develop module so that your photos are always lens corrected (she recommends doing that for every photo). I followed her instructions (they are pretty simple) and i'm getting mixed results. Sometimes when i open my photo in Develop, i see that the lens correction has been applied (good). Other times, there is none applied, and if i enable it, it applies the correction (so i know it can be applied.). All my photos are shot with the same Nikon D300, but some are shot with different lenses, and some are shot in JPEGs. I can't yet determine any pattern to why some have correction applied and others don't. Questions:
-- should this work for all photos shot with the same camera and different lenses?
-- should this work for all photos shot with the same camera but some in JPEG and others in RAW?
-- does this work only when a photo is opened in Develop?
Thanks!

that's interesting and curious -- why is that? do you recommend only using manual lens correction?
The underlying "Warping* model required for distortion correction is very processor intensive, but this is not the only factor we need to take into account. The choice of how and when to apply the profile in the workflow should be based on, amongst other things, image content, lens used, cpu and system resources. For example, does every image really need geometric distortion correction? Do some images not actually benefit from some vignetting?
Above examples actually highlight another issue (i.e. both lens distortion and vignette correction are built into a single profile). First, we have the correction of geometric distortion, which is the correction that hurts local adjustment and healing brush performance. Then we have correction of lens vignetting, which tends to brighten up the image as whole, rather than just the corners. Applying the lens profile up front will hurt when you carry out any local adjustments or healing whereas any fine tuning of overall tonal balance on an uncorrected image will be screwed up when vignette correction kicks in. So, which hurts your workflow more slow brush performance or having to re-edit tonal balance?

Does sending as PSD from LR 3.3 to PS CS4 send lens corrections and other edits?

I shoot RAW files with my Canon XTi (400D) and G12. I have a copy of Creative Suite 4 and am using it with Lightroom 3.3, which adds some goodies that ACR for CS 4 doesn't support, like being able to understand the G12's RAW files, plus doing profile-based lens corrections, improved noise reduction, etc.
If I use PSD as the format to send images back and forth among Lightroom and Photoshop, are they in synch in terms of what the image looks like, including the advanced features I just mentioned? Is there any reason to use TIFF instead of PSD?
I'd like to postpone moving to CS 5 until I'm better able to afford it - the question really is whether LR 3.3 can serve as a substitute for ACR 6.3 by writing an equivalent PSD with all the advanced features done for PS by LR instead of ACR.

I have worked with the combination of LR 3.3 and CS4 for a while.
These two are not fully compatible.
CS4 cannot read the ACR (RAW) file of LR 3.3. So when you edit a RAW-file, LR creates a PSD that is then opened in CS4.
In CS5 the RAW image is opened (as RAW) and a PSD / TIFF is created when you save your edits.
Furthermore: Lens corrections are not read by CS4 - or not completely.
I have never found a difference in quality of behaviour between TIFF or PSD, although some sources I've read say that it's better to save in PSD as it is the native format of PS.

Diference between filter Lens correction and Camera Raw Lens Correction

Whats is the main diference between tools: filter lens corection and Camera Raw Lens Correction.
I am using PhotoShop cs6, OS Windows 7
I already asked support team in Poland, but they send my back message: "we dont support any longer PhotoShop sc6"

Swila, were your "other images" previously edited in Camera Raw? I.e., do they already have saved image settings? The defaults that you save via the flyout menu will only apply to new images, or if you reset an existing image to the defaults. (e.g., choose "Camera Raw Defaults" from the flyout menu).

Lens correction and my Sony DSLR-A700

Lightroom 3 doesn't recognize my camera or my Sigma
70mm Macro. My other lens isn't imcluded yet
but my Sigma lens and camera is. Why doesn't Ligtroom recognize them? Is it me or Lightroom?

There was a similar post a day or so back for this lens. I suspect your problem is the same as the previous poster - lens ID isn't being picked up or isn't matching with current lens set.
You already know that the lens is supported so you can go to the Lens Correction panel and select it from the list under Sigma then from Setup pop-up choose Save New Lens Profile Defaults. This proile should be automatically selected the next time you activate the profile for this lens.
