I've just been offered the chance to be second photographer to a pro at a wedding which will be my first time at such an event. I want to make an impression even though the pro (who has more faith than I) has told me that even if I don't get any good shots it will be a good experience for me so there is no pressure or high expectation but still, I want to give it my all. We will start at the brides house and do both indoor and outdoor shots. I have been practicing using the camera in AV mode with the flash set to high speed so I can use ambient light and the flash just fills in (I have no problem with setting white balance). However, I have been told that the church is very old and very dark which worries me, yes I know to take the ISO up but it's the noise this produces that makes me feel well out of my league when it comes to post processing. I've looked at lots of wedding photographers websites and their images which were obviously taken in poor light look wonderful and noise free. Has any one got any overall advice they would please share and is there any software to help reduce noise. Thanks for taking the time to read.
