A bit of a noob with the DSLR, only owned it for 2 months but I find occasionally that some of my photos, especially in darker light become grainy. Just wondering if there are any tips to try and reduce this?

Learning the hard way from trial and error :thinking:, High ISO made the it worse so moved to increasing the exposure time but in dark photo's I still struggle to get clarity, like in night shots. Would this be down to lens choice or something else?

Example: excuse the poor pic, was trying some night shots of a friends car but forgot a torch and couldnt focus :bonk:. Looking at the pic, the background that is in focus is really grainy.

Setup - Olympus E-500, OM 28mm F2.8 lens on a converter, Estimates (cant remember) ISO 200, CWB 3000 & shutter 30 sec.

Can't really see the problem you're talking about, you need to put up a 100% crop.

But at 200 ISO you shouldn't have a problem, however most of the pic is underexposed which will always increase the noise levels but as I said I wouldn't have expected much noise at the ISO levels you used.

If you look here:

you can see a review of the noise levels at various ISOs.

As for clarity long exposures always require a decent tripod and also it's best to use the timer (if you have one) so you're not actually touching the camera.

There doesn't seem to be too much noise in that pic. Although, you can always use the 'reduce noise' feature in Photoshop & various other editing programs.
 
the image will look grainy as it seems the exposure isnt quite right teamed with the focus being off its a bit of a mixxed bag, i find shooting earlier in the night when theres still some colour in the sky, unless your going for a totally black background...

another option would be to take an image of the car exposed to make it white then doing several shots with the light painting and overlaying, leaving headlights on will cause you to have exposure issues with your final image unless as i say you overlay an image just for the headlights light....
 
Cheers guys, I have the noise reduction on. Probably not the best pic to how what I mean, i am still a novice so just trying to learn the hard way.

Thanks for the advise, i'm off to test the search button out :D might be easier than trying to explain what help I am looking for :thumbs:
