Create your own Lens Profiles

Did you know that you can use the free Adobe Lens Profile Creator Tool to create lens profiles for less common lens/camera combinations that work in Lightroom and Photoshop/ACR? All of the information that you need to know is here:

Or, you can go directly to the downloads here:

Lens Profile Creator (Win)      Lens Profile Creator (Mac)

Note – the Creation process is fairly involved,  so if you decide not to create your own, you can use the Lens Profile Downloader to see if anyone from the community has created on that you can download and use.

Upright’s “Reanalyze” Option in Lightroom

When you choose one of the Upright modes in the Lens Correction panel in Lightroom 5, the results are cached so that the adjustment is completely stable.  That means that if you make a change such as enabling/disabling the Profile Corrections and/or Remove Chromatic Aberration options, you will need to click the Reanalyze button if you want Lightroom to forget about those stored (cached) Upright corrections and redo its analysis of the image and compute a new correction. This feature, the ability to Reanalyze (or force an update to the Upright mode) is “as-designed”, and for good reason: in the future, if Lightroom makes changes to the Upright feature, your legacy files will open exactly as they did before.

In addition, by default, Upright will reset any crops or manual transform settings currently applied to an image. This is because rotated crops and manual perspective corrections on existing images will usually interfere with Upright. For this reason, selecting one of the Upright modes will reset the crop and manual perspective adjustments in the Lens Correction Panel (Horizontal, Vertical, Rotate, Scale, and Aspect controls). Resetting the crop has the benefit of showing the user the maximum amount of image area remaining after an Upright adjustment. To preserver these settings, Option + (Mac) | Alt  + (Win) -click when choosing an Upright correction mode.

(Thanks to Eric Chan for these insights!)

Saving Lens Correction Presets in Lightroom

When saving a Develop preset to enable lens correction check the “Lens Profile Corrections” option in the New Develop Preset dialog.  To remove Chromatic Aberration, check that option as well. The other options (Transform and Lens Vignetting) refer to the options in the Manual area of the panel and are, as a general rule, more likely to be applied on a per image basis and not as part of a Lens Correction preset (of course there are exceptions).

The Adobe Lens Profile Creator Tool

Did you know that you can use the free Adobe Lens Profile Creator Tool to create lens profiles for less common lens/camera combinations? All of the information that you need to know is here: http://labs.adobe.com/technologies/lensprofile_creator/

Note: in Camera Raw and Lightroom, the lens profile popup will only display the profiles appropriate for the file type. So if you’re looking a raw file, you get to see raw-based lens profiles. If you’re looking at a jpeg, you get to see non-raw-based lens profiles. As you can see, we have many more raw-based lens profiles available than non-raw-based lens profiles. This is due to the fact that lens correction quality for non-raw files (JPEGs, TIFFs, etc.) can be very problematic (this is because it depends on where the JPEG/TIFF came from, and how it was previously processed). For example, a JPEG that comes straight out of the camera is very different from a JPEG that somebody created from a raw file in ACR. If you try to apply the same non-raw-based lens profile to these two cases, you can get quite-different results (even though they’re both JPEGs from the same camera and lens).  Thank you for that in-depth information Eric!

LR3 – Lens Correction – Chromatic Aberration

Option (Mac) / Alt (Win) -drag Red/Cyan or Blue/Yellow Chromatic Aberration sliders to display a single color shift correction. This can make it much easier to see when the shift is corrected because you’re only viewing one color shift variable at a time.

Lens Profiles in Lighroom and Photoshop

In Camera Raw in Photoshop and in the Develop Module in Lightroom, the lens profile popup will only display the profiles appropriate for the file type. So if you’re looking at a raw file, you get to see raw-based lens profiles. If you’re looking at a jpeg, you get to see non-raw-based lens profiles.

Adobe provides many more raw-based lens profiles, than non-raw-based lens profiles. Unfortunately, lens correction quality for non-raw files (JPEGs, TIFFs, etc.) can be very problematic. This is because it depends on where the JPEG/TIFF came from, and how it was previously processed. For example, a JPEG that comes straight out of the camera is very different from a JPEG that somebody created from a raw file in ACR. If you try to apply the same non-raw-based lens profile to these two cases, you can get quite-different results (even though they’re both JPEGs from the same camera & lens). In other words, correction quality is not very stable.

Lens Correction Presets

Many of you have probably set your default settings in the Develop module so that the Lens Profile Corrections are enabled by default. But there might be occasions when you want to quickly enable/disable lens profile correction. In order to do so, I created two presets, one to enable and one to disable this option. In addition, I created a preset to enable lens profile correction for Distortion and Chromatic Aberration, yet suppress any Vignetting correction (because sometimes I want the edges darkened when shooting with a wide angle lens).

Note: you can also apply any develop preset to multiple images in the Library module. In Grid view, select the images and add the preset from the Quick Select panel’s Saved Preset drop down.

Lens Correction Profiles

PSCS5 – You can create your own lens correction profiles to use with Adobe Photoshop CS5 and Adobe Lightroom (for less common camera and lens combinations) using the free Adobe Lens Profile Creator utility available on the Adobe Labs site: http://bit.ly/ceIz7A
Specifically, Lens Profile Creator characterizes three common types of lens aberrations, namely the geometric distortion, the lateral chromatic aberration and the vignette. The general process of creating a custom lens profile for your lens involves capturing a set of checkerboard images using your specific camera and lens, converting the set of raw format images into the standard Digital Negative (DNG) file format using the Adobe Camera Raw processor, and importing the raw DNG images (or the JPEG/TIFF images if you prefer creating lens profiles for the non-raw workflow) in the Lens Profile Creator to generate the custom lens profile. You could also submit the lens profiles that you have created for your lens from inside the Lens Profile Creator to share with the rest of the user community.

In this video tutorial (Lens Correction & Perspective Correction in Lightroom 3), Julieanne demonstrated how to improve your images by reducing lens defects like geometric distortion, chromatic aberration, and vignetting. Save time by combining crop, straighten, and perspective correction in one operation.

Note: This tutorial is part of the Lightroom 3 Getting Started Series.
