Photoshop – Line Drawing Techniques for Maps

Learn how to create uneven lines that look hand drawn to use for cartography and other uses in Photoshop. Make use of Hue/Saturation adjustment to add vintage color, use brushes to create a pattern for the lines. Also, show how to render lines in black and white without any shades of grey and, lastly, how to distort them slightly. This video also shows how to add shadow around land mass and multiple lines of edging for a land mass.

Hello, I’m Helen Bradley. Welcome to this video tutorial. In this tutorial I’m going to show you some line drawing techniques for creating maps in Photoshop. In this video I’m going to show you how you can create the effect that we have here around the edge of this chart. We’re going to draw the edge. We’re going to add this shading and also create these lines so that we can see how this could be created. The pattern in the middle is just a very simple pattern fill. We won’t be covering that, but we’ll be covering everything else in this video tutorial.

So to get started I’m going to start with a new image. And I’m going to choose File and then New. And I’m going to create a very tall image. So it’s going to be 2,000 pixels tall, RGB color. Background contents of white is just fine, so I’ll just click Ok to create that image.

And what I want to do first of all is to create these lines. And we’re going to do that using a paintbrush. So I’m going to click on the paintbrush and let’s select a brush to use. And what I want is something relatively small so I’m going to start with something like this 4 pixel brush. And then I’m going to choose Window and then Brush to open this brushes panel here. And what I want to do is to set up the brush so it’s going to paint the lines for me. So first of all I’m going to adjust the spacing so that there’s increased spacing between the brush tips. And I’m going to leave the size at about 4 pixels. Then I’m going to shape dynamics because I want the size of the brush to vary.

So I’m going to increase this quite a bit so we start seeing that there’s some variety in the brush here. Minimum diameter I don’t want to change at all. And that’s pretty much all I need to do with the brush right now. And then I’m going to test it. So I’m going to make sure that I have black set as my background or foreground color, which it is here. And then I’m going to click with my brush here and I’m going to Shift click at the bottom because that will create a straight line of brush strokes. And let’s just have a look in here a bit closer at this.

You can see that we now have this sort of dotted line which is different varieties of line. Now if that’s not quite what I want I can just zoom out and we can start again. So I’m just going to undo the brush and perhaps we’ll go back and make the brush just a little bit bigger than it was. So let’s go to brush tip shape, increase the size just a little bit, and perhaps bring down the size jitter or up the minimum diameter so that we haven’t got quite so much variety in our brushes. I’m going to click here and then Shift click to finish my brush stroke.

Now what I want is a sampling of this. So I’m going to use this tool here which is the single column marquee tool, one of the few times you will ever find a need for this particular tool. I’m going to zoom in here so that I can see exactly what I’m selecting and I’m just going to click to select a single line through this image. Now that’s not the world’s best. So let’s just try again. My brush stroke is not completely vertical so that’s causing me some problems here. Let’s start this again. I’m going to click here, and again let’s Shift click to create a straight line. And let’s see if that’s a bit straighter. That will be when we click just to one side of it. So that’s going all the way through the dot.

So I’m just going to choose Edit and then Define Pattern because this is going to be a pattern. And it will be just this dashed line as our pattern so I’ll click Ok. I can now close this image because I don’t need it any longer. And let’s see how our pattern will work.

I’m going to create a new document, this time 2,000 by 2,000 pixels in size. And this time I’m going to fill it. So I’m going to choose Edit and then Fill. And I’m going to fill it with a pattern. So I’m going to select Pattern. And the very last pattern in this container here will be the pattern we’ve just created so I’ll click Ok. And there are our lines. And that’s a starter for our map.

Now with our lines we can make these bigger. So I’ve got a background layer here but I can click to make it into a regular layer. And we can just enlarge this. So if we want larger lines all we need to do is to just drag up and down on this to just make the lines a whole lot wider than they are. And because they’re lines we can just size everything like this.

If you want to make sure that that there are no gray areas to the lines, as you can see they’ve got slightly fuzzy sides here, just use Image and then Adjustments and then Threshold. And that just makes the lines black and white. They’re pure black and white now. And if you want a bit of variety, Edit, Transform and then Warp. And you can just adjust the lines with a little bit more of a curve or something through them so that they look a little less like they’re straight lines and perhaps a little bit more hand-drawn feel about them, Ok. Now let’s add our map part.

So I’m just going to grab the Lasso tool and for this exercise just draw a very wiggly sort of coastline that we’re going to use for our map. And white is my foreground color so I’m going to Alt Backspace, Option Delete on the Mac, to fill this with white. Now I want an edge around here so I’m going to choose Edit and then Stroke. And I’m going to stroke the edge with black. I’m just going to get all my tools over on this screen. So I’m going to select Black. And I’m going to make this a 6 pixel to begin with. And it’s going to be on the inside of this shape so I’ll just click Ok. And there’s our 6 pixel stroke.

Now I’m going to bring in this size. So I’m going to choose Select, Modify, Contract and I’m going to contract this by 10 pixels because I think that will be enough and then add another stroke. So again, Edit, Stroke. And this time I’m going to just use a 3 pixel stroke, but again on the inside. And then we’ll repeat that again, Select, Modify, Contract by 10 pixels and then repeat the stroke, Edit, Stroke and just click Ok. And then when I press Ctrl D you’ll see that we have the edges around here. But I’m actually just going to undo that Deselect right now because I have another piece to go in here.

What I want to do is to fill this shape with the grass so I have that as a pattern. So I’m going to choose Edit and then Fill, and again still pattern but here is my grass pattern here that I created earlier. And I’m just going to fill it with the grass pattern. Now we’re going to see how to create the shading around the edge. So I’m going to deselect the selection. I’m going to make sure I’m selected on the land, which is where the shading is to go, and I’m going to choose the Add Layer Style button here. And we’re going to choose an outer glow.

Now outer glow sounds like it should add some lightness around the edge but we can use it to add darkness. All we’re going to do is to select a dark color. Well we’ll stick with black right now. Now we can’t use screen as our blend mode. We’ll have to use something that will darken. So we’re going to choose multiply. And we’re going to set this if we want it to be full strength at 100 percent opacity. And we can adjust the size which is really the feathering around here. And the spread is how big it is. It would sound better to me if spread were really the feathering and size was the actual size. But that’s what you’re going to use.

So I’ll just click Ok. And now if we want to add this sort of sepia tone to the image, I’m going to make sure I have the image selected, and we’re going to do that with the hue/saturation adjustment layer, Layer, New Adjustment Layer, Hue/Saturation, click Ok. We’re going to select Colorized because we want to colorize this. And then we’re going to go and pick up our sort of brown color, increase the saturation and adjust the lightness. And you’re just looking for that sort of effect that is going to say vintage map to you. So I’m probably just going to select that for now.

And then I would finish off by cropping my image. We probably don’t need quite as much sea visible. In my image I have a one to one crop set here. That’s why it’s behaving a bit strangely. And there is our final result.

We’ve created lines using a brush in Photoshop. They’re all different size lines and we’ve created this sort of effect of an old-fashioned map. And actually if I just drag this adjustment layer up over the top of the fill we’ll really get that look of a vintage map.

Photoshop – Thicken and Thin out Lines

Learn to make lines thicker or thinner using a Filter in Photoshop. This is useful for adjusting scanned line art images, as well as, for thickening up lines on images which you have converted to a line drawing inside Photoshop.

Transcript:
Hello, I’m Helen Bradley. Welcome to this video tutorial. In this tutorial I’m going to show you how you can easily make lines thicker or thinner on line art images that you either scan into Photoshop or create in Photoshop yourself. In this video tutorial I’m going to show you a really quick technique for making lines a lot thinner or a lot thicker. And this is handy for images where you’ve actually converted it to line art or where you’ve got line art like this that we’ve actually scanned in.

To make the lines thicker choose Filter and then Other and then Minimum. And with Minimum you can then select the minimum radius which is going to make the image lines a lot thicker and you can test these out. Generally just one or two pixels is like all you need to do. And this is the original image and this is the thicker lined image. So let’s perhaps take this up to 4 and I’ll click Ok. And that has just thickened the line. So if that were all we wanted to do we could just save this and be off. But let’s have a look and see how we can make the lines thinner.

I’m going to choose Filter and this time, Other, and this time we’re looking at Maximum. And we’re just going to set the maximum line width. And so we want this down to something that gives us the lines that we’re looking for. So here I have it set to 5. This is what it was. This is what it is now. If I go a bit smaller the lines are going to get thicker. If I get bigger the lines are going to get thinner to the extent where they actually totally disappear. So you need to find this sweet spot here for your particular image. But if you do want to make the lines that are fairly thick right now to be a little bit finer then you can do that here with this tool. And these are again Filter, Other. Maximum allows you to set it so it’s smaller and minimum allows you to set the width so it’s larger.

Recolor Line Art in Photoshop

Learn how to recolor line art in Photoshop and how to change the colors very easily.

This video shows the use of the Lock Transparent Pixels option in the Layers Palette in Photoshop and also a Hue/Saturation adjustment layer.

Transcript:

Hello, I’m Helen Bradley. Welcome to this video tutorial. In this tutorial I’m going to show you how you can recolor your art in Photoshop. In this video tutorial we’re going to have a look and see how we could recolor this car and how we can do it in a way that would allow us to perhaps change the colors later on.

I’ve got the car on one layer here and the background which is white on another layer. So I’m going to add a layer between these two layers where I can start painting my colors. I’m going to select one of these color schemes that in an earlier video I created from Kuler and I’m going to just grab my toolbar here so that I can grab a paintbrush and a relatively hard paintbrush, not totally hard but relatively hard. I think I’ll just back it off a little bit here to about 84 percent. And on this layer I’m going to start laying down paint. I’ve got my opacity right down from another job that I was doing so let’s just kick that up.

Now I’m just going to paint over the areas where I want the paint to be. And how detailed you are with this and how accurate you are with it depends on just what sort of effect you want. Now I don’t want it to be quite so accurate so while I am going to erase a little bit of this I’m not going to erase all of it because I do want some over-painting. Now I could leave this layer underneath but you’ll see that there is a little bit of white there that’s showing through. I can get rid of this by going to this layer here and setting its blend mode to darken and that will darken the areas but will let the white pixels blend in with the layer below. I think that gives me a better result.

So let’s go now and let’s get another color in this color palette and let’s just go and paint here. And I’m just going to pick the paintbrush up rather than the eraser and let’s Just paint in these areas. Again depending on what sort of effect I want I may be more or less accurate and I can always come back with the eraser and just tidy up if I want to. Most of these areas of the image are also trapped so if I wanted to I could just make a selection from the original image and pour paint into them. But I don’t really want that effect for this image. I just want it to be a little bit more organic than that. And I’m going to add the orange to various portions of the image but I’m going to do it all on this one layer. So that means that later on I can come back and replace the orange with another color and every element that was orange will be replaced accordingly. So let’s just go here. I think I’ve got a slight problem with my green. So I’m just going to continue until I have my car painted to my satisfaction and then we’ll come back and see how we would recolor it.

Now I’ve finished painting the car and I’m ready to go ahead now and have a look at my options for recoloring it. One of the ways I can change the color of this image is to click on the topmost layer and choose Layer, New Adjustment Layer, Hue/Saturation. And this allows me to recolor the entire image just using a single adjustment layer. So I’m just going to drag here and then if I drag around on this color selector here you can see that all of the colors bar that sort of gray color are now changing. And they’re changing in the same relationship to each other. So that’s one of the options I have for recoloring this vehicle is to just adjust the hue/saturation of the entire image using a hue/saturation adjustment

layer and just stopping when I get to the color scheme that I want to use for example.

Now another alternative is if I want to just selectively recolor areas because I put each of these colors on a different layer I can then just change those layers. So for example let’s go and pick up another Kuler color scheme. I’m in beach ball but that doesn’t really matter too much. Let’s go and get this beach combo color scheme from Kuler. And if you haven’t yet watched my Kuler video and if you want to know how to do this then I suggest that you go and have a look at it.

Now my mouse and my video tool aren’t running very well together right now so I’m having a bit of trouble selecting this. Ok, it’s now in the Swatches panel. So I’m going to go ahead and select this blue color as my foreground color. And I want to replace this color green with the blue. Now what I’m going to do is because there’s a lot of detail on this layer and I want to replace the whole lot, I’m just going to lock the pixels on that layer. And what happens when I lock the pixels is if now I press Alt and Backspace, Option Delete on the Mac, what I’m doing is flooding just the filled pixels on this layer with that Color and so now that layer has been recolored. I’m going to select this layer and lock the pixels on it and pick up a color to use for it and then I’ll Alt Backspace, Option Delete on the Mac, to change its color.

And finally I’m going to lock the pixels on this layer and let’s go and get a color to use for that. We’ll choose this darker blue, Alt Backspace, Option Delete. Of course these layers are now locked so if I want to be able to edit them for example erasing any excess paint or making any changes to them, I’ll need to unlock them. But this Lock Transparent Pixels tool allows you to quickly isolate the contents of a layer, select a color to use for it and just Alt Backspace, Option Delete on the Mac, to immediately select and refill all the pixels on that layer.
