Camera Raw Lens Correction: Fixing Imperfections
https://www.shutterbuggs.com/ - One of the newest features in Camera Raw 6 are lens correction profiles. Now, this essentially puts the latest lens correction technology at your fingertips. So if we go at the top here to the Lens Correction Panel, which is the sixth in from the left, and click on it, you’ll notice you have two tabs. You have the Profile tab, and you have the Manual tab. Now, the Profile tab is a new section to lens corrections. This essentially will allow you to enable a lens profile correction.
What that will do is, when I tick it on, it will actually assign a profile to your image, according the make of your camera, which in my case here, it’s Canon, the model of my lens, which in my case is a 24 to 105 mil lens. Then it’ll assign a profile if there is actually a profile created for my camera and lens. As you can see in this particular example, there’s only one profile for that camera lens.
Now, underneath that, you have the correction amount. Now, this area essentially allows you to increase or decrease the amount of correction that’s been applied by the assigned profile. So if you’re not happy with the corrections that have been made by the designated profile for your camera and lens, you can choose to either increase or decrease the amount of corrections that they’ve made. So in this particular example, if I just do a preview of the top here, and we go on and off, you’ll notice that there’s quite a significant distortion that has occurred. It’s actually corrected that.
Now, it’s quite surprising, considering the shot is actually taken using an 80-mil focal length. So there is quite a lot of correction in that lens, even though it’s not shot at a wider angle. So if I wanted to make a correction to this, and say this made way too much… a large correction that really I wasn’t happy with, for example, I could go to the distortion slider, and I could actually correct that. I could decrease the amount of distortion they made, or vice versa, I can actually choose to increase the amount of correction that the profile has made to my liking. So it’s all sort of personal preference.
Now, what if your camera or lens doesn’t actually have its own profile? Or you don’t want to use Adobe’s set profiles that they’ve created? Well, if that’s the case, you have two options. The first is to make corrections using the manual tab, which is on the top here. I’ll just turn off the Enable Lens Correction profile, and I’ll click on the Manual tab.
So you can use this tab to make the majority of corrections that have been made with the actual profiles that have been created. So it has Transform, which is a new feature to the manual tab in lens corrections. You then have Chromatic Aberration, and you have Lens Vignetting. So you have those options available to you.
If you don’t want to use the Manual tab itself, your second option that’s available to you is to actually create your own lens profile, using Adobe’s Lens Profile Creator, which is a free software application that you can download straight from the Adobe website. I’ll actually provide a link underneath this video to where you can actually get that.
So this is Adobe’s Lens Profile Creator. Essentially what it enables you to do is create your own camera and lens profile. So if you don’t have one for your particular camera, you can create one. Adobe will provide you with a series of test shots that you can then print out. You can then set up and go and photograph in different positions and different compositions within your actual frame. So as you can see here, this one is in the center of your frame. Then we’ve got one that’s actually to the left, one to the right, one to the bottom right-hand corner, the center, the left-hand corner, et cetera, et cetera. So it’s actually putting these, your test shots, right around the frame of your image.
So it actually comes with instructions, and they’ll actually tell you what to do. But once you photograph those, you then want to actually load them into the Adobe Lens Profile Creator, and then you want to click on Generate Profiles at the top here. Once you click on that, it’ll actually start going through all those test images that you shot, and it will actually generate a profile for you, based on your camera and lens settings. So it’ll actually analyze all your EXIF data and whatnot, and actually make that profile for you automatically.
Once that profile is actually created, you can then actually save it straight to Adobe, and it’ll automatically be imported into Camera Raw for you to be able to use when you’re actually in the lens correction panel. You can actually turn it on and enable that particular profile.
