Adobe’s lens profile corrections are simply amazing. Lens Corrections automate correction of standard lens distortions, including geometric distortion, chromatic aberration, and vignette. In addition to correcting lens distortions, this feature can also be used to adjust perspective and rotation.
Adobe provides support for a growing list of camera manufacturers, camera models, and lenses: Canon, Nikon, Pentax, Samsung, Schneider, Sigma, Sony, Tamron, and Zeiss.
Adobe Lens Profile Creator
If Adobe doesn’t supply a lens profile for your particular lens you have three choices.
First, you may be able to access a lens profile created by another user on the Adobe Lens Profile Creator forum. Find and share lens profiles at Adobe labs. Of course, these lens profiles will only be as good as the creators were diligent about creating them.
Second, you can visually adjust the parameters of an existing lens profile and save the new settings under a new name for future use. There’s plenty of room for user error with this method but it’s more efficient than creating manual corrections from scratch. Expect to check the results frequently when you apply these settings to different types of images.
Third, you can create your own custom lens profile with the free Adobe Lens Profile Creator utility. Download the Adobe Lens Profile Creator at Adobe Labs.Adobe Lens Profile Creator is a utility designed for photographers who want to create custom lens profiles for their own lenses. The process of creating a custom lens profile for your lens involves capturing a series of images of a printed checkerboard pattern with your specific camera and lens, converting that set of raw images into Digital Negative (DNG) file format (using the Camera Raw plug-in, Lightroom, or the free Adobe DNG Converter), and importing the raw DNG images (or JPEG/TIFF images when creating lens profiles for a non-raw workflow) into the Adobe Lens Profile Creator to generate a custom lens profile. If you create new lens profiles, you can share them with the rest of the user community on the Adobe Lens Profile Creator forums, publishing them directly from inside the Lens Profile Creator. These profiles will then be available via new versions of the Adobe Lens Profile Downloader. This is an extended and complex process few photographers will want to go through, but for those using unsupported cameras and lenses worth the time and effort in the long run.
Using Adobe’s Lens Profile Corrections
You can access Adobe’s Lens Corrections in three locations; Adobe Camera Raw, Lightroom 3, or Photoshop CS5’s Lens Correction filter. (Lens profile corrections were first introduced in Lightroom 3. To get Lens Profile Corrections in Adobe Camera Raw CS5, you need to download a version that has been updated after the release of Lightroom 3. You can download the latest free update at adobe.com.
It’s far less destructive to make these types of adjustments to Raw files during conversion rather than after conversion. It’s also more flexible. (Use a smart object and reaccess the controls any time by simply by double clicking the smart object.) However, if you want to apply Lens Corrections within Photoshop, after a file has been rasterized, you can use CS5’s updated Lens Correction filter.
In ACR and Lightroom, you’ll find two tabs under Lens Corrections; Profile and Manual.
Under Profile, click Enable Lens Profile Corrections to activate this feature. Using the EXIF data in your Raw file, the software will automatically select the Make (of your camera), Model (of your lens), and the Profile (for that lens). You can use the supplied lens profiles, download a custom profile made by another user, or create your own (manually or with Adobe’s Lens Profile Creator).
Checking Enable Lens Profile Corrections will also allow you to access three sliders – Distortion, Chromatic Aberration, and Vignetting – for manually fine tuning the results. If you like the results of one correction but not another, you can decrease or increase the effects in one or more of the three fields.
Under Manual, you’ll find controls for visually creating your own lens profile corrections …

Seth Resnick and Jamie Spritzer, the Co-Founders of D65 announce their new book, D65’s Lightroom Workbook, Workflow, Not Workslow in Lightroom 3. D-65’s workflow is accomplished by using Adobe Lightroom. D65’s Lightroom Workbook, Workflow Not Workslow details everything you ever wanted or needed to know about the five modules in Lightroom, including setting up preferences for optimal results and organizing catalogs. Included is an entire chapter which details the D-65 legendary workflow; an advanced, yet simple workflow from capture through editing, tweaking, processing and exporting. The book also covers many digital concepts such as color space, shooting raw, file naming and archiving. D-65 was one of the first and foremost companies teaching Lightroom workflow, and the incredibly successful program has taught thousands of photographers worldwide. Seth Resnick and Jamie Spritzer are the perfect guides to lead you through the maze of technical problems and practical challenges that stand between you and a seamless digital workflow with Lightroom at the core.

It doesn’t matter how expensive your camera is, or how many megapixels are on its sensor, because this book gives you the knowledge and the discipline to make the most of the tremendous possibilities of digital photography.” – Eric Meola, Photographer
“No one knows more about keywording than Seth and Jamie. As an English major and a writer, I thought I knew a thing or two about words, but I learn new words and new ways to use words all the time from Seth and Jamie. What’s that mean to you? It means if you learn to use words like they do, everyone will be able to find your pictures easily – including you.” – John Paul Caponigro

Seth Resnick and Jamie Spritzer offer phenomenal workflow workshops – D-65. Seth and Jamie’s wisdom is apparent from the start. It’s not a my way or the high way approach. They realize workflow is dynamic and needs to be modified for the needs of the situation and individual. So they teach principles and strategies that are universal before delving into specifics. Offering a workflow they feel is ideal, they encourage you to adapt their recommendations for your specific needs, with a thorough understanding of why you do what you do and what the repercussions are. The big concepts are as or more important than the details. Efficient and consistent workflow practices increase both productivity and quality. I can’t imagine anyone, no matter what their level, not improving their workflow after taking a D65 workshop.
I’ve been saying for years that my fine art workflow is not the workflow that I should use on the weekends when my client is my mother. Mom wants lots of reasonably good JPEGs of my son, yesterday, not one perfect 2 gig file next year. I need my fine art workflow on weekdays. I need Seth’s workflow on weekends. I need different workflows for different situations. We all do.
I really need to know more about keywords and hierarchies – soon. Keywording isn’t just about my finding my images efficiently. It’s also about other people finding my images efficiently. Seth is THE master of metadata. He’s not only a great photographer, he’s a contemporary linguist. He knows all the keywords and keywording strategies that make his images incredibly accessible to anyone. I often present a slideshow of my work in Antarctica and in it I show work by the other photographers I cotaught with, including Seth. A few of his images are on my computer. When I search for Antarctica on my computer his images come up at the top of any search. When I hover over his files in Bridge I see the descriptive paragraphs he’s added to his files. Now I use his images to research my trip. Amazing.
I wish I could stay for more than one day of Seth Resnick and Jamie Spritzer’s D-65 workflow workshop this week. I love hanging out with Seth and Jamie because they’re so much fun. I need D-65 professionally too. So, my wife and I are going to attend D-65’s upcoming sessions in Miami: 2-Day Advanced Lightroom (5/29/09- 5/30/09); 1-Day Web Workshop (5/31/09); 1-Day Business Workshop (6/1/09).

This week at The Fine Art of Digital Printing workshop (taking place at Brooks sponsored by Epson) Mac Holbert and I reviewed file structure at the end of the week – by processing student work. Everyone participating in the workshop got a valuable review of the file building workflow Mac and I use and recommend. Steve Robeck also got more than one possible window into the art of interpreting digital files. Time and time again, you modify how you apply a tool, eliminate it from the process, or add another. In this case we added a Photo Filter adjustment layer applied selectively to the highlights to add subtle warm ambient color and we used an additional Hue/Saturation layer to increase the saturation of yellow accent colors throughout the image. Adopting a consistent file structure and working methodology is important. And, knowing when and why to make exceptions is equally important.
