I recently discovered a fantastic tool for creating images for web sites - the "Trace Bitmap..." option in Flash. For those who haven't experienced this superb tool it can take a bitmap image (be it a gif, jpeg or whatever) and convert it into a flash vector, with astonishingly high quality results. Here's my dilemma. If I take a copyrighted image and apply this process to it, then modify the image to a large extent, is it ethical (or legal) for me to use the new image in my own work without express permission of the copyright owner? Case in point - I recently found the following image of a rose on the web (via google image search): http://www.kyrene.k12.az.us/schools/brisas/sunda/enchantment.htm With the aid of "Trace Bitmap" I created the following - something I would not have been able to do without the original image: http://www.bath.ac.uk/~cs1spw/nemesis/side-rose.gif It is virtually impossible to tell that the one was derived from the other, and although I am not at all worried about the legal implications of using such an image I am held back by my ethical concerns (especially as I would love to use this technique more in the future). A what point (if ever) does a derivative work free itself from copyright restrictions of the original? Regards, Simon W.
