These are the resources that Jo Hart johart1.edublogs.org
and I used in the graphic manipulation Elluminate session on 24 April 2009.

PhotoFiltre http://photofiltre.free.fr/download_en.htm
  • Lots of features
  • Easy to use
  • Good starting point for people who are new to this
  • Windows only
  • Runs quickly
  • Will run on most computers
GIMP http://www.gimp.org/downloads/
  • Fully featured – rivals Adobe Photoshop
  • Takes a bit of learning
  • Recommended for people who want to do more
  • Windows and Linux
  • A bit slower
  • Needs a mid-range personal computer
POVRAY http://www.povray.org/
  • 3-D modelling tool
  • Used to make the initial white button used in the Elluminate session
  • Having a mathematical inclination makes it easier to use
  • Windows and Linux
  • Runs reasonably quickly
  • Will run on most computers

In case you want it, here is the “source code” used for creating the white button in POVRAY:

global_settings { assumed_gamma 2.2 }

#include “colors.inc”
#include “textures.inc”

#local ObjectColour = color red 1 green 1 blue 1;
#local Thickness = 90;

camera {
location <0, 0, -760>
// right <424/160, 0, 0> // Enable this line to stretch the button vertically
up <0, 1, 0>
sky <0, 1, 0>
direction <0, 0, 1.8>
look_at <0, 0, 0>
}

light_source { <50, 200, -100> colour Gray30 }
light_source { <-20, 40, -20> colour Gray30 }
light_source { <100, 80, -100> colour Gray50 }
light_source { <-200, 100, -100> colour Gray50 }
light_source { <-400, -400, -300> colour Gray50 }
light_source { <400, -400, -300> colour Gray50 }
light_source { <-400, 400, -300> colour Gray50 }
light_source { <400, 400, -300> colour Gray50 }

background { color red 0 green 0 blue 0 }

sphere { <-150, 0, 100> Thickness pigment { ObjectColour } }
cylinder { <-150, 0, 100>, < 150, 0, 100> Thickness pigment { ObjectColour } }
sphere { < 150, 0, 100> Thickness pigment { ObjectColour } }

    Hi Phil, thanks for writing up a comparison between the different image editing software. I’ve now written the post from the session and have added your post link to it.
