I'm now through reading the manual to my Canon 20D for the third time. Every time I read it I learn something new. Some how the first two times I completely missed the part about the eyepiece cover, which is supposed to be used in self-timer or remote switch mode because "stray light may enter the eyepiece" and affect the exposure. Do people have any real time experience with this? Is it really that necessary?
Also, as I contemplated having to start using the eyepiece cover, I began to think about the proper workflow needed to take stunning long exposures at night. This is what I have come up with; am I missing anything?
1.) Use a tripod and make sure tripod is steady (obvious)
2.) Attach remote switch (also obvious)
3.) Enable long exposure noise reduction (C.Fn-02 set to 1:On)
4.) Enable mirror lock up (C.Fn-12 set to 1:Enable)
5.) Compose photograph
6.) Set the mode dial to M and set shutter speed to bulb
7.) Set desired aperture
8.) Slide cover over eyepiece
9.) Press shutter button on remote switch once to activate mirror lock up
10.) Press shutter button on remote switch again to take photo
Am I missing any steps?
