| p.1 #12 · Basic flash question, please help! |
First, I can't thank all of you enough for your help. I really appreciate it.
I guess I did not use the right terminology when I spoke of zero and manual exposure. I do mean perfect exposure. When I put the camera in manual exposure mode, as opposed to aperture or shutter priority mode, I get an exposure bar with lines to indicate stops. Each stop has a shorter line to indicate one third of a stop. The left side of the bar has stops representing under exposure. The right side has stops representing overexposure. Right in the center is a zero to represent perfect exposure. I should be able to change the ISO , the aperture size, and/ or the shutter speed until the exposure "zeros out " at the center. I hope I have expressed myself better now.
I have been afraid to raise the ISO too high because of introducing noise. Also, often I cannot use a tripod because I am following active children or pets around the house. As a result, I have tried to keep the shutter speed at at least 1/50. I use TTL with the SB600. Again, I would appreciate any further advice that you might have. I hope I have explained things better now. Thanks so much.
We get exactly what you're saying.....You don't NEED a perfect "zero" exposure when you're shooting with flash....if you're in manual mode, in a completely dark room, at 1/50s, f/2.8, and iso 1600, your meter in the viewfinder will read like very under exposed....but when you set your flash to TTL, it will pop with enough power to give you proper exposure, b/c your FLASH EXPOSURE COMPENSATION isn't set + or - anything....if you set your FEC to -1ev, then it will pop with only enough power to give you 1 stop under exposed image....How do i know this is correct? b/c i just did it....trust me......
So i guess stop trying to get a perfect "zero" exposure when you shoot flash.....it wont happen, and you dont need it....that's why you're shooting flash in the first place.....
