Flash with the Nikon 8008s I have a Nikon 8008s camera and a SB22s TTL flash. My question is in regards to flash. I notice that when using the TTL flash the camera recoginizes that flash is being used and makes the appropriate setting changes (f-stop, shutter). I also have a Vivitar 285HV flash. I would like to be able to use it too. However, I notice that when it is installed on the camera, the camera does not know that the flash is there and therefore sets up as though it will be shooting with only the available light. I would like know how to choose then the appropriate shutter speed and f-stop knowing that I will also be introducing flash to the subject.

John, To use this combination of 285HV and your 8008, you will have to operate your 8008 in manual exposure mode. If you look at the base of the 285HV you will see only one contact in the middle of the shoe. This is the flash trigger to fire the flash and that's the only connection. Unlike your Nikon flash, the camera cannot control the flash output. "Auto" flash output is controlled by the sensor on the flash. Your 8008 will X-Sync shutter speed up to (and including) 1/250th. You should be able to use any shutter speed between 1/60th and 1/250th without any problems. Set the camera's shutter speed to one in this range. Your f-stop setting will depend on your film speed and how much power you want out of the 285HV. To use the 285 in "Auto," look at the side with the round calculator panel. Set the pointer on this to the film speed you are using. Now look at the color bands. These will show the aperture settings you can use and the distance range the flash will have for different settings on the flash sensor. Pay attention to the minimum distance also. The 285 is a fairly powerful flash. If you crank up its power too much for the distances you are using and shoot something closer than the minimum distance, it will likely overexpose. This is because the flash cannot quench itself fast enough to keep from putting out too much light at distances less than the minimum. Once you have decided how much flash power you need, make note of the color and the aperture for it. Then look at the side of the sensor on the front. You should be able to rotate it and change the color showing on the side of the sensor. Set this to the color you want. Then set the lens aperture to the one for that color on the calculator panel. Don't change the lens aperture to another one unless you also change the sensor on the flash to the color on the flash calculator panel that matches the new aperture. You should get proper exposure. Under certain conditions with very bright light sources in view of the sensor, such as a powerful lamp or a window (during the day), the sensor can get fooled resulting in under-exposure of the intended subject. It shouldn't happen very often, but these conditions are something to look for when using the flash. -- John
