In the previous movie, I introduced this concept of how we can work with RAW or DNG files and how these images are changed by a way of working on different settings, and then where those settings are changed, whether in a catalog or with the file. Well, here let's take a little bit more of a practical look, and let's start off with working with RAW files. So, I have this RAW file that came directly from a camera, and it's of my daughter Sophia. Now, one of the things that we can do is make a change in Lightroom. So, I'll go ahead and press the R key, and I am going to crop this image.
I'm going to make a pretty significant crop change there, and let me go in even tighter just so we can really see this. And then I'll double-click to apply. I'm going to increase my Color Temperature a little bit, a little bit of Fill Light, little bit of Contrast. So definitely made some kind of significant change to the photograph, right? Well, where have those changes have been saved? Well remember, by default the changes are being saved to the Lightroom catalog. So in other words, if I were to right -click this image and choose Show in Finder, what I would see is that I have the image. I have the sidecar file but none of the changes are made inside of this file.
In other words, if I were to double- click the file here, it would open it up inside of Adobe Camera Raw, without the crop, right? You can see the image hasn't been cropped. You can also see that it hasn't been warmed up, or any of the other settings I've applied are not part of this file. Rather, all of those settings are inside of the Lightroom catalog. All right. Well let's cancel out of here and go back to Lightroom for a moment. And how can we then change that? Well one of the things that we could do is let's make yet an even more significant change. Let's convert to black-and-white.
Let's do something that we can really see here. We can go to our catalog settings. On the Mac, you go to Lightroom and choose Catalog Settings. On a PC that's under the Edit menu. In Catalog Settings, we're going to choose Metadata. Now, one of the options that we have is to Automatically write changes into XMP. If I click on this option, what's going to happen then is this particular file, any of the changes that I make, will actually go to that sidecar XMP file, will travel with this file.
The change will be a little bit more local. In other words, rather than having the change inside of Lightroom catalog, the change is now in a sidecar file. So, we can either turn on that preference which would mean, every time we make adjustments to a RAW file, here is another one. If I made an adjustment here, it would save it to a sidecar file. Or let's say then, rather than doing this globally, what we can do is go back to Catalog Settings, turn this off, and let's say we want to do this just to a single image, or for that matter, to a group of images.
We could make a selection, whatever the case. In those situations, what we can do then is we can go to our Photo pulldown menu and here we can select Save Metadata to Files and this will then manually save this data to the sidecar XMP files. So, for example, if I were to select one of these images and then right-click or Ctrl+Click and choose Show in Finder, what I would see as if I were to double-click this image now, it would open it up inside of Camera Raw with whatever settings I've applied. All right.
Well let's quickly jump back to Lightroom. So again to reiterate, we have two options. We can either turn on one option so that this happens all the time, and that's the option where we're going to go to our Catalog Settings, and in our Catalog Settings, turn on this Automatically write changes to XMP. So again, that would happened globally with every RAW image that we work on, or if we prefer another technique, which is a little bit more manual, a little bit more image-by-image or group of images by group of images, in those cases what we're going to do is navigate to our Photo pulldown menu and here we're going to select Save Metadata to File. All right.
Well now that we've seen how this works with RAW files, what about the DNG format? Let's take a look at that one in the next movie.
