Now that we know a little bit about the benefits of working with the DNG format, let's take a look at a few preferences. And also a few techniques that we can use in order to convert our images to this particular format. Now before you actually start to work with DNG, one of the things you want to do is navigate to the preferences dialogue. Here we'll navigate to Lightroom and then select Preferences. In doing that, this will open up our Preferences dialog. What you want to do is navigate to the area which is called Final Handling. When you click on that tab, you have some options when you covert your images to DNG upon import.
Now here, what you want to do is typically leave the default settings on as is. Yet let me talk through what our options are here. In regards to extension, I typically like to have lowercase extensions, so I choose the lowercase option. Although both or either of those options will work well. For compatibility, you want to double check to make sure that you're using the bottom option here on this list. This will ensure that you're using the latest and greatest version of Camera RAW. Next we have the ability to generate or render what's called a JPEG preview, this allows us to see the file more quickly, and again in most situations the default setting here of medium size will work well.
That being said, if you have a really high resolution monitor you may want to generate a higher resolution JPEG preview, yet in most situations for almost all of us the medium size JPEG preview will work well. Next we have the ability to embed fast load data. This allows us to view and to work with our images much more quickly. So you almost always want to leave this check box turned on. Now last, but not least, we have an option which allows us to embed the original raw file inside of this quote DNG container. That will then contain the DNG file, as well as the original file. One of the reasons why you might want to do this is if you want to make sure to have all of that original data if you're concerned of getting rid of that or throwing it away.
The down side of course is that it's going to increase your overall final size very significantly. So on my own workflow, I leave that check-box turned off. Alright, well next what we will do is go ahead and click on the Import button after having dialed in those settings. When we import our photographs into Lightroom, we can choose the option which allows us to copy as DNG. When we do that, it will take advantage of all of those preferences which we've just defined. Now, I've already talked about how we can import and copy as a DNG in another place, so I'm not going to go through that here. Yet I simply wanted to highlight the connections between our preferences, and also between this dialogue here.
Well let's now go ahead and click Cancel and take a look at another scenario. What about the scenario's with this image here. This is a native RAW file. This was the image as it appeared out of the camera and it's a .CR2 file. Which is the type of file that my Canon camera creates. Well, let's say that I want to convert this to the DNG format after the fact. I didn't do this upon import, but now I want to do this in order to be able to take advantage of DNG fast load, and the other things that are good about the DNG format.
To do that, we'll navigate to the library pull down menu and then you can select the menu item which is convert photo to DNG. Here we'll go ahead and click on that menu item. And this will launch our convert dialogue. Now up top we have a few options. We can only convert the RAW files, and that's typically what you'll want to do. You wont necessarily want to convert your PSD, or TIFF, or JPEG files. Rather you most often will want to do this just with the RAW files. Next you can choose to delete the original files after successful conversion.
This will help you to maintain a pretty clean and organized library. By doing this you'll only have one version of the file as part of your catalog. If you leave this option turned off what will happen is you will have two versions of the file, one would be the native RAW file. The second would be the DNG. And again, that just tends to get pretty messy. So if you're going to convert to DNG, I recommend you commit to the process. And you turn on this check box, which will ensure that you'll delete those original files. So that you'll only have that DNG file. Now that being said this decision is completely up to you, so you don't necessarily have to do that, I'm just telling you what I do in my own workflow. Alright well here we have some similar options that we've seen before. File extension, I like lowercase, compatibility, choose the latest and greatest version of Camera RAW.
JPEG preview medium size, then here we want to embed fast load data so we can work more quickly with our files. We'll talk about lossy compression in the next movie, so I'll leave that off for now. And then also, I'm going to leave off the option to embed the original RAW file. I want to get rid of that file and simply convert this image to that DNG format. Well to do that we would simply click OK, and what would happen is it will then take this file. It would then save it in the exact same location and it would save it so that we could now work with it as a DNG file.
