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.
Before we get into Lightroom and talk about how we can white balance or color correct our photographs, I thought it would be helpful to step back for a moment and talk a little bit about color temperature. Now here we can see we have different color temperatures from warm to cool, and we can have warm colors like a sunset, or really cool colors, like we have at dusk or night, and of course, we have other situations in between. Open shade, overcast, clear day, morning and afternoon light. And so what white balance has to do with is how we deal with these different situations.
For example, if we capture an image in open shade it's going to have a blue cast. So what we'll need to do is then color correct for that in order to make the image look neutral or for that matter, in order to enhance the image a little bit, and to change the overall color temperature. Now color temperature is also affected by light sources. For example, on one side of the spectrum we could have on-camera flash, which typically emits about 6500 Kelvin, and that's a really cool tone.
Or on the other side of the spectrum we could have something which is lit by candles, really warm tones down here about 1800 Kelvin. And we have a number of different situations between, whether it's studio lights at about 5500 Kelvin or tungsten lighting, which is at about 3200 Kelvin. So the whole point here is that color temperature varies based on the different light sources or the context that we're in. So how does that relate to Lightroom? Well in Lightroom one of the things that we'll discover in the Basic panel is that we have a number of different ways to control or to work with or to correct or to enhance color temperature.
For starters, we have White Balance, currently, As Shot, or I can choose Auto, which will attempt to auto correct the situation. Or Daylight. You'll notice that my color Temperature and Tint will change as I make different selections from this pulldown menu. And what this can do for us is if we know how our photograph was captured, we can choose one of these options in order to color correct or white balance our photographs. All right, well what about the other controls here? We can also simply click and drag the sliders. Temperature, we can either make this more cool or warm, or Tint for that matter, green or magenta.
We can also select the White Balance tool. You can select it by clicking on the icon or by pressing the W key. Now if you have the Navigator panel open when you hover over an area of your image, you'll see a potential color correction option, if I were to click on this area of my photograph. And what you want to do is click on something that you think should be neutral. In this case, I'm guessing the shirt was probably black, so when I click on that area it then makes that spot neutral and then color corrects the image accordingly.
All right, well now that we know a little bit about color Temperature and a little bit about how white balance works inside of Lightroom, let's go ahead and dig a little bit deeper and take a look at a few examples in regards to how we can apply this knowledge to some of our images, and we'll do that in the next few movies.
