Alright, so I’ve had this since June, but figured I’d blog about everything else first.<\/p>\n


\nThis is a door peephole. I bought the biggest size for under RM40, with a viewing angle of 170 degrees.<\/p>\n


\nBut guess what happens when you put it in front of a camera! (Yes, that’s my pocketable Canon Powershot A520. I do not have a big camera!)<\/p>\n


\nFisheye, baby.<\/p>\n


\nThe distortion made the satellite dishes on the left look suggestive on the right. I had to get closer to get the dishes to fill up the frame. Note the strong chromatic aberration, or purple fringing.<\/p>\n

This can be countered in Photoshop by going to Image – Adjustments – Hue\/Saturation…<\/b>, choosing the color channel closest to the purple fringing (usually Blue or Magenta) and then decreasing the Saturation and Lightness.<\/p>\n


\nWhat if you took an already curved surface? More distortion!<\/p>\n


\nA normal fisheye mirror…<\/p>\n


\n…seen through a fisheye lens.<\/p>\n


\nSurprisingly, the fixed focus front camera of my Nokia N70 wields decent results. Another issue with the fisheye is that the brass keeps it a distance from the lens, making it hard to have sharp focus at the center of the image. So I have to focus as close as possible, and choose as dark as aperture (F7.1 is safe) to get a sharper image.<\/p>\n","protected":false},"excerpt":{"rendered":"
