I have been shooting with the Canon 1D the 550 for about a year. Try this though you might have to make some changes according to your specific lighting situation. Get rid of the stofen, I have used them and its very hard to get a consistant lighting with it, plus also you probalby trying ot spread your light to thin withthe stofen. Used a bracket or on put the flash on the camera, go plus 1 on the flash to get consitant results , you may even have to go more than that when shooting the bride as the white dress will cut down the flash and cause all the photos to be under exposed. I suggest getting an expo-disc as the lighting will be more conssitant when using this product as you will need ot take a white balance of each room of lights you shoot in .
I also outside when using a flash use shutter priority and aperture priority , depends on the lighing outside. You will also need to adjsut your flash accordingly to knock the shadows off , I have in some situations went - 1 up too +2 on really harsh shadows really depends on the sun .I like shooting the camera aperture priority at F4 and let the camera set the shutter speed and that makes a great portrait out side, plus it gets your background really out of focus.
Though these are things I have tried, digital is a whole new ball game and everyone must try things for thereself. I shoot and work on problems I have all the time. I have gone to churches in advance to work on lighting situations. I have even had to set lights up to get a more even and better product where with film I could have used a flash on a bracket and got away with it.
Digital is great but there is a very high learning curve and it is not for everyone , you must be more concerned with your exposure and that is what is gonna separate the photogrpahers of the future. I have shot photojournalism style with a photographer just recently , I had never seen them work before but they just stuck a flash on the camera and started shooting away not once did htey use a meter inside or outside, of course they we shooting film. I would never do that with digital.
Good luck and more questions jsut email me at
