In Photoshop Lightroom 3 Essential Training, author Chris Orwig provides a comprehensive look at Adobe Photoshop Lightroom 3, the popular photo-asset management, enhancement, and publishing program. The course covers indispensable techniques such as importing, processing, and organizing images in the Library, correcting and adjusting images in the Develop module, and creating slideshows, web galleries, and print picture packages. In addition to exploring all of Lightroom 3's capabilities, this course is rich with creative tips and expert advice on photographic workflow. Exercise files accompany the course.
Now that we've dialed in our preferences, what we want to do is take a look at how we can take advantage of these two different settings. We have our typical settings, and then also this Additional External Editor. So, let's close the Preferences dialog, and back in Lightroom, we're going to navigate to the Photo pulldown menu. What you're going to notice here is we have the option to choose Edit In. Now, this is for the first set of settings, and then here is the Additional Editor. Now, one of the things that happens is it's a little bit awkward to know, okay, well, which one should I select, because they both look pretty similar.
Now, if you want more distinction, what you can do is navigate back to our Preferences. On a Mac, you go to the Lightroom pulldown menu; on a PC, that's the Edit pulldown menu, and choose Preferences. What you may want to do here is for your Additional External Editor, you may want to save this as a preset. I'm going to go ahead and click on Save Current Settings as a New Preset. Here, I'm going to name this as a preset in a way that makes sense based on my options. What these options will do is they'll help me remember how I defined this particular Additional External Editor.
I'll click Create here. We can see that we can access that from this pulldown menu in this way. All right, well, let's close Preferences. Now, back in Lightroom. When you now go to the Photo pulldown menu and choose Edit In, we now have our top two options as is. These are the typical ones. This is the Additional External Editor. Then we also have these different presets that I can create. Sometimes it's helpful to have these, because again, these words trigger my memory and say, oh, yeah, that's what I was thinking.
What about actually working on these files in Photoshop? We can use the shortcut, or we can use the long cut. The long cut for now, let's take a look at it. Edit In. I'm going to edit this photo in Photoshop CS4, or on a Mac, it's Command+E; on a PC that's Ctrl+E. I'm going to select that option. It will then open up the image inside of Photoshop. What I want to do is open up these two different images and then make a couple of comparisons. So, this is the real big file, the biggest file that we have here. Let's go back to Lightroom.
Now, in the Photo pulldown menu, we're going to go back there, Edit In. In this case, we can either choose Edit In > Adobe Photoshop CS4, or use a shortcut or use a preset. These two are identical. All right, so I'll go ahead and click on that option, and I'll edit it this way. Once this image is open inside of Photoshop, it's saying, hey, you know what, this image is in this sRGB color space. Currently, Photoshop is dialed in or set up to work in ProPhoto. What do you want to do? Well, I want to use my sRGB.
So, I'll go ahead and leave the default option, use the embedded profile, and I'll click OK. All right, well, now I have two files that are open, and let's take a look at these two files. Let's try to compare them a little bit. Here you can see that this one is currently in sRGB, and this one is ProPhoto. Now, you can change what is displayed at the bottom of the screen here, by clicking on this triangle, and then choosing Show. So, let's go ahead and go to Document Sizes. In this case, this one is 48 MGs. Let's compare that over here. We're going to show our Document Sizes.
This one is 97 MGs. This is the one in 16-bit. This is the one in 8-bit. You can also see that by going to the Image pulldown menu, and choosing mode, and you can see this is an 8-bit per channel image. In contrast, the other one, going to the Image pulldown menu > Mode, this one is a 16-bit per channel photograph. So, what we can see here is that these images are definitely different. Now the dimensions are identical. I just want to point that out briefly. If I go to Image and select Image Size, we can see this one is about 5,000 pixels wide, about 3 tall.
Let's hit Cancel, look at the other smaller photograph. We go to Image and Image Size, again, 5,000 wide, about 3,000 tall. The whole point here is that what's happening when we're editing in Photoshop is it's taking the full, huge file, but if we can apply a few different things, in this case we looked at how we could apply a different resolution, so we changed the Resolution. We also took a look at how we could apply different bit depth and then also color space. So, there are times when you may want to have a couple of different options dialed in, so that you have flexibility.
Now, what options you actually use in this Additional External Editor are completely dependent on your own preference, basically how you work. You may find that that's a little bit overkill, that really, all you're going to do is simply work to Photoshop with the highest settings. Although, in other situations, you may discover, you know what, the highest settings where I'm generating this file, like we can see over here, that's just gigantic, well that's just overkill for my own workflow. So, for in those situations perhaps, our Additional Editor will be at 8 bits versus 16, or whatever it is in order to work a little bit more effectively.
All right, well, now that we've been introduced to our External Editing Preferences, and now that we've started to take a look at how this will work in small ways, let's dig a little bit deeper into this topic, and let's do that in the next movie.
