Subject: Re: Do I need a mirror-lock?

My experience with gems and other still objects and long exposures is that
your flowers are more likely to move than the camera.  Re: mirror
lock-up..... I find after using cameras with and without it that the shake is
brief and only affects the image at the begining of the exposure.  So, two
solutions will give you sharper images:  first, if you use really long
exposures (say more than 10 seconds) the movement will have been long stopped
and the percentage of the image made when the camera was still will far
outweigh the amount made just after the shake; second, if you put a black
card below the lens as you open the shutter, wait only a second or two and
remove the card, you will have blocked out the camera shake entirely.
