psquared Posted July 4, 2007 Share #1 Posted July 4, 2007 Advertisement (gone after registration) I was planning to take some photos of fireworks today with the M8. Is there any way to turn off the noise reduction off? I haven't found a way, and it looks like I'll miss half the shots waiting for noise reduction to go through its thing.

andybarton Posted July 4, 2007 Share #2 Posted July 4, 2007 Shoot RAW? Link to post Share on other sites More sharing options...
psquared Posted July 4, 2007 Author Share #3 Posted July 4, 2007 Well, I do shoot RAW, but the camera insists on doing in-camera noise reduction routine with slower shutter speeds. For example, if you expose for 4s, then you can't take another shot for about 4 seconds while the camera does its noise reduction thing. Link to post Share on other sites More sharing options...
harmsr Posted July 4, 2007 Share #4 Posted July 4, 2007 As far as I know, no there is not any off for it. On long exposures, the camera shoots a black frame (same exposure time as the original shot) to remove the noise. This is in RAW. Silly maybe, but I have never shot in-camera jpg with my M8.

I haven't found a way, and it looks like I'll miss half the shots waiting for noise reduction to go through its thing. That is a great question. I doubt it can be turned off which would be a good idea for many NR programs. However, be forwarned that there is NO noise reduction program that can be nearly as effective as the noise subtraction program that Leica is using for long exposures. This thing really works. It is the standard program in astrophotography. No one would do a long exposure without it even if the CCD was actively cooled. But it does double the effective exposure time of every shot. Well worth it though. Rex Link to post Share on other sites More sharing options...
Shootist Posted July 4, 2007 Share #7 Posted July 4, 2007 Advertisement (gone after registration) Depending on what f/stop you are using and the distance you are from the works and the lens MM you are using you might not have to wait. I guaranty one thing, if you shoot fireworks with a 4 second exposure at say f/2.8 or 4 and you're not a mile away from where they are going off all you'll get is blurs of light. I'll be doing the same tonight. I'll post back what I find. I will be fairly close to where they are set off from. Link to post Share on other sites More sharing options...
luigi bertolotti Posted July 4, 2007 Share #8 Posted July 4, 2007 Nothing to do for noise reduction, and I have seen it works very well when you take long time exp on static subjects: I have not yet experience with fireworks with M8, but have taken many shots of them with M4, and my mood is that is better NOT to use long times: my best shots were taken with 400 ASA film and 1/4 1/8 or so (do not remeber the f stop): when it will happen, I plan to try with M8 set at 640 or 1250 or even 2500 and quick times : I suppose is the best way, but just a supposition.
