Should I use SilverFast or Photoshop?

From: Scanning with SilverFast

Video: Should I use SilverFast or Photoshop?

In this movie I'd like to address the topic of Scanning versus Photoshop. Which adjustments should we apply during the scan and which ones should we apply during Photoshop? And I want to do at the beginning of this particular special scanning chapter, because there are lots of tools and techniques that we're going to introduce and use in this chapter that you may or may not want to apply during the scan. And to make the point and to help aid the discussion I'm going to redo one of the scans we've already done, and it's the octopus scan. Let's just magnify this, and let's just go ahead and do the scan that we did earlier and just talk about what we're doing here and what we want to do in Photoshop.

In this movie I'd like to address the topic of Scanning versus Photoshop. Which adjustments should we apply during the scan and which ones should we apply during Photoshop? And I want to do at the beginning of this particular special scanning chapter, because there are lots of tools and techniques that we're going to introduce and use in this chapter that you may or may not want to apply during the scan. And to make the point and to help aid the discussion I'm going to redo one of the scans we've already done, and it's the octopus scan. Let's just magnify this, and let's just go ahead and do the scan that we did earlier and just talk about what we're doing here and what we want to do in Photoshop.

First thing is, we did overview scan and we'll go ahead and name this the Octopus 1200, we're going to set 1200 pixels per inch resolution, okay. And then we want to set a Color Sampler Point or Densitometer Point back here. We saw there was a 6% white background. At this point we don't really have to remove this in the scanning program. We're going to but we don't have to. We could just do the scan and remove it in Photoshop. If your goal is to scan your image, get it ready to print, and then send it off to the printing company, it's Friday afternoon, then you want to do all of your editing right here.

Save it out as a TIFF, and boom, it's gone and ready to print. If on the other hand, your goal is to capture a good quality image and then you want to apply some editing in Photoshop this maybe easier to see or you want to do it more than one time, you want to have variations, then you may not want to do all of your editing here in your scanning program. You may want to save some of it for Photoshop. So let's do some here and then some in Photoshop and then finish up our discussion. So what we're going to do is we're going to decide I do want to remove the background here, remember this is when we use the Histogram and the Info on our Densitometer reading which was a 6% gray background, and we see the spike in the Histogram which we know now is the paper.

So we can use that Histogram to help us remove all that white background without getting rid of any of the data in the actual image, and that's all we need to do here. But remember we could do this in Photoshop. We're going to choose to do this here and then something else in Photoshop in just a minute. And remember that many of the tools that we have here in SilverFast, such as the Histogram and the Gradation, these are just SilverFast versions of the venerable levels and curves tools that we have in Photoshop and they serve exactly the same function.

So again it begs the question of when should we be doing these various settings? All right, once the scan is done, let's go ahead and open that image in the application which has been designated to open TIFFs which in my case is Photoshop. And we see we've got a beautiful scan here, no doubt it. And notice that automatically we have a layer that we can work with in Photoshop. So one of the things I can do is I can set to duplicate this layer and then I'm going to apply some Unsharp Mask to this as one of the variations that I would like to do. So I'm going to zoom in because I want to show you what we can do, and just use this as an example.

Sharpen>Unsharp Mask. I want to put this all the way up at the maximum of 500, and then I'm going to put the Radius at 25. And notice what happens to those detailed dots inside of the octopus. Now as that back this off down to 5, notice how the nature of the image changes even if I put a Radius of 1. The image looks much different at those various settings. This is just an example of one thing that I can do. And I can do it on multiple layers, I can make multiple versions, and I can see it at any magnification very quickly. That's why I want to apply this particular adjustment in Photoshop.

I can do a lot more things in Photoshop than I could during the scan in SilverFast. Can I apply Unsharp Mask during the scan with SilverFast? You betcha I can. But then I'm not going to end up with this amount of editability. My issue is, I want some editability, so I'm not ready to go to print yet. On the other hand, if I was very happy with printing this, no reason why I couldn't sharpen that up a little bit in SilverFast, save it out as a TIFF and then just send it off to the printing company. So it depends upon what your objective is. So before you start your scan think a little bit about what you want to do where, how much you want to apply during the scan and how much editability you want to have once you get into Photoshop.

With that in mind let's go forth and try some special scanning projects.
