just been reading all the advice everybody gave to a newbie. Good and very helpful it was to. Well here is another newbie wanting a bit more. Iv'e got a Canon 1000d I set up the shot go the push the shutter button and I get a "busy light " blink in the corner of the viewfinder, I then move to another area do a test shot,sometimes it works, then go back to my original shot and take the pic.the thing is why does this happen sometimes? I hope Iv'e explained it right.
