Still, I&#8217;m trying to be conscientious, dog knows why.<\/p>\n<p>Herewith, a demonstration of the Perspective tool in GIMP, Photoshop being very similar. This is a handy method of skewing a layer, often in order to correct something that got skewed by our camera work or shooting angle, sometimes by lens distortion. But it also allows us to purposefully skew the image (or the layers thereof) for compositing or creative purposes.

However, the <em>upstairs<\/em> fan is there too &#8211; quieter, but it still switched on in the middle and left behind a hum. Noise Reduction and Noise Gate in Audacity removed some of this, mostly between sentences, but it still pops in just to annoy the piss out of me.
