So you want a model of your city. You could go to the hobby store, buy some foam core, carve out the city, add some paint, some decorative touches like trees and people, and six months later you might be halfway started. Or you could just take a picture and let Paint.NET do the rest! This is a technique known as Tilt-shift photography (Wiki this), and what it essentially does is fake a smaller depth of field (Wiki this). The tutorial you're about to read is adapted from this photoshop tutorial. It will teach you a little about the Alpha Mask, about Gradients, and maybe even a little about photography! You'll be turning So, here we go! You Will Need: -1 Photograph, preferably taken from above. It improves the illusion if it's taken from far above the ground. It also doesn't have to be a city: it can be a mountain, a train station, a highway overpass...pretty much anything large that you would like to make smaller. -Ilnab1024's Alpha Mask Import Plugin. Step-by-Step: Step 1: Open your image. First, duplicate the layer ( :DuplicateLayer: ). Name the new layer "Blur" if you're into that sort of thing. Step 2: Run "True Blur." (If you can't find it, click here.) Run it with a radius between about 7-8 (you can fiddle with it a little bit, but 7-8 should be about right). You'll end up with this: (click to enlarge) Step 3: Add a new layer. Name it "mask" if you like. Now, with the colors left at their default black and white, choose the Gradient tool ( ) with the "Linear (Reflected)" mode, as shown below. Click on the focal point of your picture, and hold Shift. Drag the gradient until the black is a decent size. Then release the mouse button before you release shift. This keeps it in a perfect line across the photo. You'll end up with this: (click to enlarge) Step 4: You may have noticed that it's a bit less than perfectly blended as a gradient. You can fix this pretty simply by running Frosted Glass. (If you can't find it, click here.) Run it with a Maximum Scatter of about 6, a Minimum Scatter of about 1, and a smoothness of about 3. Again, you can fiddle with this, but that should be about enough to give you a good "grainy" look. This should leave you sitting pretty on this: (click to enlarge) Save the file as a .PNG in someplace that will be easy to find later, such as your desktop (don't worry, you can delete it without fear once you're done). I saved mine as "mask.png." Edit: Don't forget to Undo (Ctrl+Z) when you're done with this step, so the flattened image goes back to a layered image. Step 5: Deselect the "mask" layer, and select the "Blur" layer again. Your Layers window should look like this: Now run the Alpha Mask Import plugin. (If you can't find it, click here.) Click on "Browse..." and find the "mask.png" file you saved earlier. Result: Once you hit "Ok," you're done! You should end up with this: How cute! Now you can add extra finishing touches such as maybe a hand entering the shot, little people on the ground...also, upping the saturation really adds to the "toy" feel. Anything, really! Try it out and post your result. Quote The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.Amy: But how did it end up in there?The Doctor: You know fairy tales. A good wizard tricked it.River Song: I hate good wizards in fairy tales; they always turn out to be him. Link to comment Share on other sites More sharing options...
