Subtitles of the Movie

Now, we're going to take a look now at another setting that is very important to be aware of. Now, I learned this the hard way having once pulled my hair out not understanding why my image's color was changing while I was posting my images to the Internet. So pay attention here if you want to avoid frustration. Now, when opening files in Photoshop, they will generally have one of two gamut settings assigned to them when they come into the program. Now, if you don't know what gamut is, see the VTC tutorial Adobe Photoshop: Mastering Core Concepts or do a Google search on color gamut, that's g-a-m-u-t and then come back to this movie. Now, your gamut setting will either be SRGB or Adobe RGB. Your digital camera will assign one of these two gamuts to the image when you take the picture and once you bring it into Photoshop, the problem begins when Photoshop wants to change the gamut setting, thereby altering your color scheme. Now let me show you want I mean. In order to check what the gamut assignment is on this image, you right click on the blue bar here, find file info and this'll take you to the xf information on this image and hit advanced and then go to the Adobe Photoshop properties and you see that the profile is, well, the color space is Adobe RBG 1998. Now let's check to see if the working space matches what is in the image. And the way you do that is go up to edit, click on that, come down to color settings and you click on color settings and indeed we can instantly see in the working space's dialog box that the setting is Adobe RBG 1998. So everything is all well and good as long as you're planning this output to print. But now, let's see what happens when the image is saved as a JPG destined for the web. And we go to file, save for web and devices and then we see here that the image on the right is different from the image on the left. That's because the color space has been changed by Photoshop to match what the web wants in the way of color spaces; that is, the SRGB color space as opposed to the Adobe RGB color space. So when you go to save this, you're going to have a different color scheme than you intended when you finished your adjustments. Now, this has the Adobe 1998 color space and it looks flat to the eye because here on the SRGB color space, this has been changed to an eight-bit image. This is a 16-bit image and it's been adjusted with fewer color gradations and so it has more contrast and therefore appears on the Internet to have more pop and more detail. But if you were to print these out, the result would be exactly the opposite. You'd get a much better result in prints by printing the Adobe RGB color space than you'd do an eight-bit JPG in the SRGB color space. So how do we make sure everything matches? Well, you have to change the Adobe color space before you open your image. And again, to review, we click on edit, color settings, the Adobe RGB color space is indicated in the working spaces dialog box and the way you change that is just go to the drop-down list, find SRGB, click on it and there, it has been changed. Now we open our image that has the Adobe RGB color space assigned to it and we see what happens. Photoshop will say we have a conflict. The document's colors will be converted to the working space. click OK and indeed, the image has been changed. RGB is indicated in the xf information in the image. Since that's been changed, we can now go to save file for the web and we see the color balance is perfect. In other words, what you see on the screen is actually going to appear on the Internet and that is the importance of matching the color space between Adobe RGB and SRGB in Photoshop and in your camera settings.
