any tips on light painting?

[Mashburn]

My biggest problem is increasing exposure in lightroom and a lot of noise coming out. Then having to fix it a lot. Is there a way to help prevent this? Any other tips?

Just do a longer exposure if needed

What ISO setting are you using? Perhaps lowering it would help reduce noise.

I'm wondering why you need to increase the exposure in lightroom? Couldn't you make some adjustments to your exposure in the camera? i.e.: longer

Increasing exposure post process always makes image noise more visible because of the way digital photos work.

I shoot light painted classic still life, with a 50mm lens, iso 100, f22, for 30 seconds, in an almost completely dark room [whatever light can come thru the closed blinds & curtains]. You need to correct what you're doing while shooting [iso, ap & shutter] in the given situation. Light painting takes a lot of practice, but if your camera settings are right and you're painting the light onto the subject enough at the time of exposure, you shouldn't have to adjust much, if anything, lighting wise in post processing.

Thanks. that is what I needed to know. That is a higher Aperture, so I will play with that. but everything else is close to what I have been told and do.

I shoot at 100. I'm not sure what causes it.

That is a higher Aperture

Actually it is a lower number (it's a fraction - f/22) and a small lens aperture.
F/22 says the lens aperture diameter is 1/22 the lens focal length (f), whatever the lens focal length (f) happens to be.
If the lens focal length is 50 mm, @ f/22 the lens aperture is 2.27 mm wide (50 mm / 22 = 2.27 mm)
Aperture - Wikipedia, the free encyclopedia

An image quality issue to be cognizant of when using a lens aperture as small as f/22 is a likely loss of focus sharpness due to diffraction.
