Review the scanning techniques graphics professionals and photographers use, while delving into workflow considerations and the advanced image-quality controls available in most scanning software. Author Taz Tally explains the core concepts, such as how resolution and interpolation affect scans; introduces the industry-standard SilverFast scanning software; and shares the settings to achieve the best results from a scan. The course also covers keeping your scanner and its parts clean and free of dust, and includes a variety of start-to-finish scanning tasks.
Even though this is not a Photoshop class and it's not really an image editing class, I would be remiss if I didn't cover just some basic touchups for touching up images in the post-scan. Throughout this course I've been harping on cleanliness is next to godliness and wear your lint free gloves and clean your images and clean your scanner to the point that is probably sickening to you. But the fact is it really is important. But the other real world fact is that, no matter what you do, unless you work in a really, really clean environment, you are likely to end up getting some dust in your images. Heck, even I forget sometimes to change my gloves enough, or I forget to clean the scanner one last time, or I am putting the image down and a piece of dust floats in, so you end up with.
And here's that picture of Roberto that we scanned, and sure enough, we've got some dust and scratches here that need to be fixed. So I am just going to show you the quick and dirty ways to take these out, and it's really effective. First thing I want to encourage you to do however is make a duplicate layer and we're going to call it as Background- touchup, so that you don't injure the original image, and you can always go back to the background if you want to. And basically the tool that you are going to use here is a Spot Healing Brush. I am going to go ahead and close the Layers panel. we know which layer we are working on. And this works really, really well.
And basically just take this tool and make it a little bit larger than the dings that you're working on. And this tool honors the current underlying tone, and in a lot of cases, like on this jacket, that underlying tone is what creates the fabric itself. So you don't end up ruining the fabric, unlike using the Rubber Stamp tool. So I typically don't use the Rubber Stamp tool, I'll use this tool here. And notice, the more dust there is, the more time it's going to take. So hopefully this makes the point about why we really do want to get as much dust off of our images as possible.
And notice when you apply Sharpening, it just makes them worse, as we saw here, as we see in this image. So use that Spot Healing Brush tool, and it's very, very effective. And after you've done this a couple of times like this, then you'll more likely remember to clean your scanner and wear those lint free gloves. All right, So there's touching up.
