Hello Good People, Is it possible to alter the colour of a light source within the shot similar to how one might increase its intensity, say the equivalent of a dimmer? I have a bright spotlight on a character and over the two to three minute diatribe I want the light to go from white and then very, very, very slowly become warmer, perhaps reaching magenta. The brightness must remain constant and only the colour change. Does anybody know of a lighting system that could work for this? Many, many thanks, Stav.

Many thanks for your replies guys. It is much appreciated. Martin Radic. :ph34r:

Good day to you all, I am about to shoot a commercial on the Sony DVW-790 and I am very keen to experiment with a diferent type of lens other than the standard Canon J series. I am especially interested in knowing more about the "electronic cinematography lenses" that are available at present. 1. With the so-called "film style" lenses, for example the Optex 7.8 - 164mm, would the characteristics of the depth of field be similar to that of an Angenieux (11.5 - 138mm) or a Zeiss (11 - 110mm), given that all our conditions are identical? Are the digital lenses responsible for video's apparent infinite depth of focus and therefore, with me using the J20a (Optex conversion) or the Cooke Videtal, my depth of field would be greatly reduced? 2. Some of the shots involved in the job have the camera tracking in from about 20ft to filling the frame with a beermat. Unfortunately it seems the budget cannot afford for me to have too many lenses and therefore I am trying to find a lens that is roughly 8-60mm with macro capability. Could anybody advise me on a lens that might fit these specifications? 3. If one was to pull focus from 20ft to 10" how much barrel shift can one anticipate? 4. I have also become aware that the lens measurements on a digital lens are slightly different to those on a film lens. 8mm on a J16 ain't 8mm on a Zeiss Distagon. Could somebody please explain to me the reasons why? Ideally I should go into a hire company and check all this out for myself but there is not too much time left. Finally, if there are any unforeseen points that I should know I would greatly appreciate them. Your advice and suggestions are much anticpated. Martin Radich.
