Lewis Downey: Zone Systema photographic technique(Untitled)- August 29, 2003 More about textures from Marc Torzynski:There is a proverb () in France: (which means "let pass some time and things will go clearer by itself"). Another one states that if you are in trouble, better ask some friends about the subject. To get better help, I put them in practice together and have some discussion with a friend of mine last night. She's not a scientist but works at a contemporary art museum and she had several ideas on what makes a texture and what makes an image. So we...http://carbonphoto.cicada.com/zs/2003/08/29.html#a480 (Untitled)- August 28, 2003 Here is another excerpt in the conversation with Marc Torzinski about a laboratory definition of a texture and using the emergence of textures in the calibration of film tests. Interesting stuff. Marc: "Hi again! Regarding your first mail, I am not sure that I am really willing to model a texture creating it trough CAD program (Photoshop, 3D studio...) because I am convinced that we will be fooled by such artificial modelling. The idea of making a "laboratory textured object" by use of...http://carbonphoto.cicada.com/zs/2003/08/28.html#a478 (Untitled)- August 27, 2003 I am enjoying an excellent discussion with Marc Torzynski about defining a definition for textures. Marc writes:You hit exactly the point! Let me first fully agree with your interpretation of texture as a result of the interaction between light and a three dimensional surface. As you point out, the appearance of a surface will depend on the light properties (very directionnal light from one side - highly textured surface, diffuse light coming from above the surface - nearly no texture at...http://carbonphoto.cicada.com/zs/2003/08/27.html#a476 (Untitled)- August 27, 2003 I do not know that we must define textures by the luminance range, but it might be a useful element in a definition. It seems to me there ought to be some way to model an extremely simplified texture. Maybe Photoshop or a 3D rendering program would be helpful in figuring this out. To get a handle on the basic properties, try reading a surface with shadows on it -- both the shadowed and illuminated parts. This subject could be a driveway and your shadow. Watch out for those specular...http://carbonphoto.cicada.com/zs/2003/08/27.html#a475 |
