I recently got myself a Canon Ixus 55, great little camera. I do a lot of achitecture shots. My Canon 300d is ideal for this but sometimes I need to use the Ixus. There's is terrible lens distortion on the Ixus, it having a small lens and that. Is there a tool or Photoshop plugin you would recommend to correct this? I can correct images manualy using the various transform tools in photshop but I've got 100s of pictures here that need to be corrected!
