Re: I tried, it is hard!

OK, The 285 is an excellent Flash, But you need to understand how the sensor works. It is meant to receive a reflection from the subject, and then shuts off the power when it reads enough. So when you put it on a umbrella, the reflection is read from the umgbrella, which is no good. You need to set the sensor to manual, and then use the flash with he umbrella in a controlled invironment to know what power the flash is putting out at a given distance. If you have a meter you can borrow, it will be quick. simply attach a 15' string to the flash, and take readings. tie knotts at 2.8, 4, 5.6, 7.1, 8, whatever you like ... make it simple. Then you can go to work. Go outside, and possition your subject, then take a meter reading from your camera in manual mode. set your aperature to a corresponding knot, then get to an appropriate shutter speed ... something under 1/200th ... let say the backgroung reading is 5.6 @ 1/125, simply move your flash to a distance at the 5.6 knot, and fire away .. Done ... or you can underexpose the background a bit, so say your manual reading of the background is 2.8 @ 1/60 ...simply set the flash to the f4 knot distance, set your camera to f4 @ 1/60th, and fire away ... your subject will be properly exposed, yet the background will be 1 stop under ...

Once you get accustomed to the flash, you won't need the string anymore, and can work from knowlege ...FWIW...HIH ...
