No, any compensation for exposure is void if the camera can't go on in changing values. If you choose P, the camera will change shutter speed and aperture until the end of the line, and then only the remaining room for one value. But shooting TV, you signal that you want to use this value. If the camera reaches the end of the setting range for aperture, the aperture in the finder should blink showing range overload.

As with other mirrorlike reflective curved objects you have to light something that will reflect into the car then. This is usually a large white thing. Shape and distance of the white thing make up the reflections in the car. > I think a cp filter might have taken care of the > glare from the museum lights, No. It would have reduced direct reflections from non-metallic surfaces. But it would not have been able to change the light quality. > and assuming the flash caused minimum glare, No. The flash causes a full reflection on curved elements in the cars that have their curve in your direction. Direct camera mounted flash is the least useful light for car photography. Take a look at what professiuonal car photographers use: Huge softboxes and indirectly lit reflectors that very often exceed the size of the car by far. The white front of the softbox is then reflected from the car surface making the impression of form possible. You certainly have some sort of a toy model car around your house, and you certainly have a small fluorescent working lamp (handheld, with cable). Set the model car on your table and experiment with the working lamp. Look how it reflects into the model car and you will have an idea of how to light cars. -- Michael Quack <[EMAIL PROTECTED]> * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
