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.
After you've performed your pre-scan the next order of business is really setting your scan frame of your image. Whether you're doing an automatic or a manual scan now is a good time to go ahead and set the scan frame. The scan frame is this outlined red area here. What that designates is the actual portion or area of the image is going to be scanned when you finally click that ultimate Scan button when you're all set up. You can actually set the color of this in your options. You probably want to start for just a manual kind of get close to where you want it.
Let's say if we wanted to 5x7 scan, you can just manually drag it over there with the default settings. With the default settings this is the area where you're really going to be designated the scan frame and you can see the results of any resizing that you do here. You'll watch these numbers here and here at the original and then the output will change. So you get it close to what you want. Then you can move over here and you can get it exactly right if you want to. Let's take a look at a couple of different scenarios.
Let's say that you wanted your original frame to be 5x7 and you will find these fields to be a little squirrely sometimes. They seem to change on their own. they have a mind of their own. If you put in 5.0 and 7.0 instead of just 5.7, you'll have better luck. Watch to the scan frame over here. I'm going to Shift+Tab to move backward. You can Tab from one field to the other. If I go 4 point and as soon as I hit the point that red line comes to move in. Sometimes it moves in without the point, sometimes it doesn't, but the point always helps.
If I go over 6, notice it didn't move that time and then point, then it actually moves up. So I'm going to hit that point that kind of tells that red scan frame to actually move. So Shift+Tab move about here. We'll go 5. And see how it moves and then 7.0. So go ahead and just put in the whole number and be sure to use that point even if you using full numbers. Then I'm going to Tab forward here, and I'm going to 5.0, Tab 7.0.
Notice we are at 100 and 100. Then what I like to do as soon as I set my output. See this is the size of the original frame here and then this is going to be the output dimensions of the final image. Then I'm going to click on these two and it holds that in position. It holds that output at 5x7. So no more interpolation will occur. Whatever we scan that's what's going to be held. Notice that I can then move my scan image anywhere that I want to. So if I were to move that down here I'd get part of this white area that actually be captured.
So by clicking on these locks, it locks that frame area. Sometimes depending upon the dimensions in the image you may want to actually zoom out a little bit so that you can see that scan frame location. Remember to use that multiple or higher-resolution prescan to give you that capability without having to rescan the image. Just another scenario. let's unlock this again. Let's say you wanted to change from the 5x7 format and you wanted to go to 8x10. So we started with a 4.0 and then a 5.0 and then we wanted to output this at 8.0 and 10 and notice do you see this little proportion here. That's turned on.
It's turned on by default and generally you want that turned on. Otherwise, you'll get non- proportional scaling which is not a good thing. Notice when I put in the 8 the 10 automatically filled itself in here. Now when I click these see I've set a 4 inch by 5 inch original frame. Now I can move this around anywhere I want to. When I complete the scan I'll end up with an 8x10 image. This framing and scaling data here interacts with the resolution data that you see down here and we'll discuss that in the next movie.
One side note to mention about setting your scan frame and this may happen to you where we've placed a 5x7 image down on the scan bed. In this case a flatbed scanner with a glass platen. If we nudged it all the way up to the top to get the top edge of the image, square with the top edge of the scan platen and then we place the 5x7 scan frame in the image and then we scanned it we end up with this little white space down here at the bottom and that's because on some scanners, and this particular one as well, the scanner doesn't quite read all the way to the edge of the scan platen and that can be a little frustrating if you want to get the entire 5x7 image.
So what you can do is what I've done here is I've actually taken the image and I've offset it from the top of the scanner and the easy way to do that just take a short straightedge ruler, usually a metal ruler works best, and just lay the ruler parallel to the top edge of the scan platen and then nudge the image up against it. As you can see down here in my prescan I placed little piece of light stick tape down at bottom to hold it in place. So this edge is still perfectly parallel to the top edge and these edges are parallel to the side edges.
I've just offset it using my ruler in the nudged this edge up to the top of the ruler. Then when we set our scan frame and we complete our scan, we'll just call this a Test scan, we end up with an image instead of having that little white area in the bottom. we've actually captured the entire 5x7 image. So you may have to do that on some of your scanner beds. It's a less of a problem with dedicated thumb scanner, because they're right inside their holders. You just get a steel flat edge and it works best if it's a short one.
So doesn't overlap the edges of the scanner body itself from the glass scanner platen.
