More questions on MLU
« on: February 13, 2006, 09:24:22 AM »

Hi everyone. I am new at this site. I am amateur photograper. My passion is nature photography. I own Nikon F75. This is maximum that I can afford to myself at the moment and in near future have no possibility for better camera. I Have read on this site about MLU. Unfortunately, my camera, has not that "option".
My question is:
1. can I expect to fix sharpeness of a picture in Photoshop if there is no way to lock the mirrow in my camera?
2. If I`d tackle hard my camera to a heavy tripod would it help? Or should I think about different camera anyway?

Any coments, please...

Thanks

Actually, MLU is most appropriate for a fairly narrow range of shutter speeds - roughly .25 sec to 1 sec.  Faster or slower than that and the vibration induced by the mirror bounce is not much of an impact.    

My advice is go with what you can afford and use a remote release, or if your camera can do a delay, use that.  At the speeds where MLU is effective, the other major contributer (IMHO even more of a problem than mirror slap) is the vibration induced by pressing the shutter, a delay or cable release will deal with that.

Thanks Tim

I do use remote in my steady shots. I like shoting in conditions of long exposure. So mirror vibration is actual to me. (I always wondered why my pics are not as sharp as I want them to be. Now I realised.) Anyway, for this time I will use equipment that I have and will correct sharpness in Photoshop. (A little disapointed, though, about Nikon because of lack of MLU).

Thanks again.

Wait, do you mean, taht if I`m shoting at slower  then 25 sec. speed, then mirror vibration is not that important? That sounds prommising.

Jus to be sure you understood what Tim said: it's between 1/4 second (not 25 sec) and 1 second
