h00ligan Posted December 22, 2009 Share #1 Posted December 22, 2009 Advertisement (gone after registration) I tried several things with the d'lux 4 - only had a few minutes to run out. I wasn't trying to shoot anything wonderful, simply to understand and get to know this camera more. First the details Shot in a median with traffic moving about 40 mph on either side Slight light left in the sky the most pleasing result came at 2 second exposure at f/2.0 iso 80 Now, I'm wondering if any of you could advise what exposure could have prevented some of the noise I see in the sky - or is it that I used a low aperture and the light was too dim - so in an attempt to recover information it created that noise? I'm hesitant to post the photo, because frankly it was a hurried effort and I suck at photography to begin with (there's also a bright white piece of litter that draws all attn!) - and i see some really great stuff here. I fluctuated between the posted specs and 5 seconds at 2.8 but didn't do a whole bunch of steps in between due to time constraints. It strikes me that perhaps I should have done more in the middle and less on the extreme ends for a better quality photo. If necessary for input I will post the photo, but it's a completely uninspired composition with basically no merit other than an attempt to learn a thing or two about the camera. Thanks for taking the time to read this, and if there is a better forum to post this in please let me know - as I don't want to inundate you all with such simple things most, if not all, of you have mastered. edit -- it also strikes me now that instead of using full manual I could have set the iso limit to 80 and used shutter priority mode - seeing what the camera then recommended.. probably a good thing for me to do to learn.

Advertisement Posted December 22, 2009 Posted December 22, 2009 Hi h00ligan, Take a look here Photog Newbie 101: Just shot my first long exposure with a tripod. I'm sure you'll find what you were looking for!
regedit Posted December 22, 2009 Share #2 Posted December 22, 2009 my amateur advice for long exposure (I also tried a lot with my d-lux): close the aperture at f8. you'll get beter (longer) DOF focus manually - long exposure are not snapshots so you have time to check focus as you like, beside camera focus rather strange in very low light. set ISO at 80. take even long exposures .... I had some night exposures at 60s. With ISO locked and 80 you are in full manual Use exposure bar indicators to under or over expose to create nice effects - sometimes in the night a bit underexposure create good night feeling and emphasis light sources even more. in street photography and speeds over 15s at night you will get light tails but no cars (interesting effects) have fun doing that! good luck!

stuny Posted December 22, 2009 Share #3 Posted December 22, 2009 The vibration of the traffic might cause some blur in the situation you describe. Regarding the noise, lower ISO will reduce that, as will some post production noise reduction followed by sharpening. Link to post Share on other sites More sharing options...
wda Posted December 22, 2009 Share #4 Posted December 22, 2009 I echo Stuart's advice. I enjoy low light with a tripod. Noise is not usually a problem. However it is easily dealt with in Lightroom or Noise Ninja plugin. Link to post Share on other sites More sharing options...
