- Now that we've got the images on the computer, let me walk you through the process of loading them into the Lens Profile Creator. First up, you're gonna need to get those images out of Lightroom. Select the range of images that you want to use and choose File, Export. I recommend that you export to your hard drive as a DNG. Click Export and target a folder. I'll work off my Desktop for now. Make a folder called ToProfile, and inside here make a couple more folders.
First up, D600 and I was using an AF micro 60 millimeter. We'll call this Shot1. Copy that to my clipboard, Create. We'll put those in there. You can see that it's exporting the nine files here at the top. Then, grab your other set and export those.
File, Export. All good. I'll just put this into another folder, paste that name, and call it Shot2. Create, Open. Those write out, and we can do our fisheye lens too. Select those, File, Export. I'll click Export, go up a level, make a new folder, and this is the EM5 from Olympus with the Lensbaby Circular Fisheye.
Target that, and let the files write. Once the files are out of Lightroom as a DNG, you could bring those into the Lens Profile Creator. Let's start with that first rectilinear lens that was pretty straightforward. Minimize Lightroom here, and I've already launched the Lens Profile Creator. I'll now choose File, New Project. This makes an empty project, and I could choose to add images to that project.
Navigate to the folder that you created, and select the first set of exports. Choose all the DNG files. You'll note that DNG, JPEG, or TIFF are supported; I recommend sticking with DNG. Remember, a DNG file is just a RAW file wrapped into the digital negative container. This is Adobe's non-proprietary RAW format. You're going to need to convert your RAW files into DNGs in order to use them with the Lens Profile Creator.
I'll open those up, and they're pulled in. You'll note that it found a lot of information here about what was happening. In fact, because this lens had direct information included in the lens data, it actually read the name of the lens as well as the camera. The profile name is a combination of the two: a Nikon D600 with the 60.0 mm macro lens. Notice it also recognized the version of the chart: the 27 x 45.
It found that the point dimensions and all of that lines up with what was on the bottom of the chart. Looks like each of those squares is 30 pixels, so it meets our minimum definition. As we take a look here at this group, it's pretty straightforward. Now, let's add another set here. I'll choose to add that second set of images to the project. Let's just go to Shot2, select those all, and click Open. Now, you'll notice it automatically added another Focus Distance Group.
We could turn that on as well. Now it found those. Technically, with the prime lens it wasn't really a focus distance, but we moved the camera and that's gonna give us two sets of data to work with. Before you generate the profiles, make sure you check your Preferences here and look at the Camera Cache. Choose a drive that you have write permission for. Go to some place like your Documents folder, and just make a New Folder called Lens Profile Cache.
And select it. First up, make sure that your profile is stored in a place that's easy to find. In this case, I went into my Users folder, selected my user folder, accessed my Library, Application Support, Adobe, CameraRaw, LensProfiles, and then chose version one of the Lens Profile Creator and put the profile in there.
I can then choose Select. You can store these profiles anywhere and manually load them, but if you put them in a location like this, it's gonna be easier for other tools that rely upon Camera Raw to find it. Then, make sure you double check your Cache. Choose a folder that you have write access to, and then click OK and you'll be ready to run the tool. As it goes through, you'll notice that it's detecting the grid on each image, and when it finds it, it's able to turn that into information that the Lens Profile tool will use.
Looks like it's found it, prompting me to save, and I'm just storing this as an lcp file which is the Lens Profile. I'll click Save. It now moves on to the second set. With a prime lens, you can often get by with just a single length. You would use these multiple lengths here if you were dealing with a zoom lens. Remember, we say with a zoom lens ideally you get all three: the widest, the tightest, and the middle.
But getting this extra set and saving it as a second profile just gives you a fallback position in case you'd like to experiment with the two different profiles. Let's name this v2 and save. I've got a project here, so let's just save that project in case we wanna come back to it. Here in the Lens Profile Creator, it navigated to a default position, and I'll just call this Nikon D600 - 60mm and save my project.
Now we can make a new project and add those fisheye images. Let's add the images in and select our Lensbaby Circular Fisheye. Once those images are added, it's important that we specify that this is a fisheye lens. I'll manually add the lens name in.
Looks good. Let's add the camera name here. Just so we have a little more detail. There we go, and we'll name the profile LBCF for Lensbaby Circular Fisheye. Looks good. Read everything over one more time and click Generate Profiles. It's gonna go through and analyze that and attempt to detect the grid on all of the nine shots. It did a good job.
As that moves around to different compositions, you'll see that the circular fisheye adds quite a bit of distortion. Looks like this one image was problematic that it had a hard time detecting that. Perhaps the squares got too small at the edge, and it's warning me in this case that the chromatic aberration was not able to be successfully completed. However, the distortion did go through, but it seems that some of the images were a little bit too small, so I'll need to go back and try re-shooting those in order to accurately create this profile.
Now that you've seen the process, both succeeding and failing, you have a pretty good idea on how capturing the test chart and running it through the Lens Profile Creator works. I've put together a collection of images that I've shot with, and I wanna walk you through what the lens profiles actually do. Why don't we transition and we'll go into the development mode, and I'll walk you through some of the settings that the lens profiles can correct for and show you how to make some manual tweaks.
