Screencasters Episode 099: Tilt-Shift Miniature

BestVideos — Wed, 16 Dec 2009 16:52:58 GMT

In this screencast I will illustrate how to make a tilt-shift miniature photo using Inkscape 0.47pre4.

The final image in this screencast is a little hard to see so if you want to take a look at something better then take a gander at this picture.

Also, check out Tilt-Shift Maker for an even faster way of making these images. Have fun.

Meet the GIMP #97: Shrinking! (2)

After a welcome to the (hopefully) lots of new viewers from the Miro Guide, I continue to shrink a real building site to a model train scale.

An important tool for this is the Focus Blur plugin. The homepage needs some assistance in translation from Japanese to English - are you able to help?

The Focus Blur plugin needs a “Depth Map”, a grayscale image which defines the amount of blur in each part of the image. Rob A has made a tutorial about making a believable depth map. It’s not enough to make a simple gradient, you have to keep things with the same distance to the focal plane on the same level of gray and make the gradients follow the planes in the image. And here my subect turned out to be too complicated. My result is not as good as I wanted.

If I wanted to do this again I would choose a different subject and camera position. Higher up and farther away and so including more stuff. And I would look out for regular shapes in the area to make building a depth map easier.

(EDIT 04/03/09) A much better example than I was able to produce was made by the above mentioned Rob A. He describes his process in the forum thread.

Again I steal an idea from the forum. It’s making fake tilt shift images. They look like images of model railway landscapes but are made from reality. Have a look at the forum for links to images by Bert and others.

I do half of the work in this podcast - planning the image and give the real world a plastic look. Next week I’ll add the focus blur that is so typical for macro shots.

But at the start I show that I have learned something from Philippe: Look carefully at an original. The image on the right is a H0 scale model in the sand on the Weser beach - real plastic.

The companion file contains the original shots - the xcf will follow next week.
