I have a Canon 7D and recently found the EOS Lens Registration tool. I've used it to put the profiles of the lenses I own into the camera. That part all makes sense. What I'm more confused about is how useful it is to my particular workflow.
Looking through the manual, I see that it can use this data for the Peripheral Illumination Correction. But it also says that Peripheral Illumination Correction only works in-camera for JPEGs and to use it with RAW files, you must use the Digital Photo Professional application. I have never used this app and don't plan to as it complicates the workflow and will likely make doing my RAW processing in my preferred application harder. (EDIT: This Question and its answer explain why working with Canon DPP and Aperture (or any other RAW processing app) is a no-go.)
Further, I see there is a setting in the camera's menu for "Raw Image Processing" which appears to use some of the other data from the lens registration, such as lens distortion, chromatic aberration correction, etc. This functionality is not documented in the manual. I think it may have come with a firmware update. (I currently have firmware version 2.0.0 installed. I will probably update it to the latest which I think is 2.0.5 when I have some free time.) (EDIT: Found this feature on their website. It produces a JPEG in-camera in case you want to send directly from camera to customer.)
When I select "Raw Image Processing" it shows me the current image. If I change the settings and "save" it appears to write a copy of the image to the card. (I assume it has the settings I changed applied.) So this would probably be writing a JPEG file, right?
I'm currently using Aperture to work on my photos. At some point I'll switch to an app that's still being updated, but for now, it works for my purposes. I also have Adobe Photoshop CS 5.1. I have tried selecting the "Lens Correction" action under "Automate," but when I select a file it tells me:
Error: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.
- The command is not currently available
So is there anything useful I can do with the lens registration data given that I work in RAW and process my photos using Aperture. If I were using either Lightroom or a more modern version of Photoshop would they use the data?
