Before I decided to post this I've read a series of post about the "battle" of flashes ( Canon vs Nikon) and couldn't find the answer to my dilema so I decided to ask for your help. I shot a wedding recently together with a guy who was shooting Nikon and he told me that he switched from Canon to Nikon because he shoots with flash a lot and the Nikon flash system is so much better. Being a Canon shooter I took that to heart and I argued that it's not true, Canon is just as good. So he challenged me to a test. We were shooting inside a ball room, so we set the cameras to the same settings ( ISO, shutter speed and aperture, I don't remember the exact settings) and we did some tests. We shot in manual mode, aperture priority and program mode. To my surprise and disapointment hes images were better than mine. The images had people dancing in the foregraund and other people at the tables in the back ground, my images were only well lit in the foregraound but the background was dark. His images( remember we were shooting at the same settings) wre lit form foreground to background. For me to get the same result I had to bring down the shutter speed at like 1/30 of a second while his were at around 1/100 of a second. Even today I have to bump up the ISO and bring down the shutter speed to gather light in the back of the picture. I still believe to this day that the reason for this is because I don't know how to use the flash settings right despite the fact that I read the manual ( and books and on line articles) inside out. What was I doing ( still doing) wrong, why he's images at the same settings were so much better? How can I improve on this, and were I can go ( on line or books) to learn how to use the damn flash better? It's hard for me to believe that Canon doesn't make a flash system that is just as good as Nikon's. Thank you for your time, you can rip me a new one if you think I deserve it. Thank you. Ciprian.
