My daughter plays a few musical instruments for a performing arts group, and i have become a member of helpers at their concerts. I have been asked to take some photo's of the upcoming concert (whilst they are playing and some shots of the performers with some special guests), but when i have taken photos at the location in the past they have come out all blurred and yellow looking.
They perform in an auditorium which has a high ceiling and brightish lights.
The camera i have is an CANON EOS350D, with the following equipment. EFS 18-55MM & zoom lens EF55-200MM, COBRA CX150 FLASH, i also have 2 tripods. If there is anyone out there that could help me with some settings or some advise I would realy appreciate it. Thanking you in advance.
