C2040 - Night Shots

[Kevin]

Hi, would like to check with other C2040 owners. I start getting noise at 4s and onward under ISO100 (firmware upgraded) . Do the rest have the same problem from 4s onward? 2s and below do not have noise. 3s do not have but after a while it start to have noise. Please share your experience at what s onward do you get noise...

[hong]

how bad isit, you may want to show us some eg

mine on upgraded firmware, iso100 can expose up till 10 sec without much visible noise, till you zoom in 400%

[Blitz]

Mine, more than 10secs and tat's it....

[Jayan]

My C-2100UZ has noise at abt visible at 6 sec.....earlier if the CCD starts to warm up.

[Blitz]

Correction....sorri I think mine is about 8 secs.....

Sigh....got 16s long exposure also cannot put to full use, such pity

you still can use it, after taking the picture, use photoshop to remove the noise.

OK here come some e.g, (BTW they are NG shots). I realised I do have a 4s shot without noise. But later on, even 2s get noise. I gues the DC warm like Jayan said. Need you guy to confirm and also confirm what i see in the photo is noise.

Would appreciate any feedback...

Looks good, dun see any visible noise, first photo need a tripod

[Kevin]

How come my photos don't show up?

not much visible noise, but if you used a tripod, the photo will turn out even nicer cos I think all the photo suffer from a little bit of hand shake

[volk]

from the photos I only saw handshake..those bright dots could be due to handshake and are not noise..

Kevin: when is the free course?...I almost forgot abt it. I also have not upgraded my firmware (or remap) yet. No time to go down esp when they only during office hour

hmm..I see more jpeg compression artifacts than noise.

Oh yah about the class, I am still WAITING for Blitz to fax in his form!

BTW, according to Megadark, the course run from 6.30 pm to 10.30pm. He feels that 80% of the course cover something he already know as a newbie. The 20% that he learnt is very good. So the catch here is speding 4 hrs and 20% is useful for you!!!

Sorry, my mistake. Didn't know PS6 auto clean up for me. Didn't check before I post.

Anway, I post another unedited one. IF you guy find it too slow let me know. I figure that this section don't display the picture and you guys have to go over to homex so is not violating the rules.

Hmm...pai seh ah I'm getting forgetful lately.... ok ok I will put in my gurantee card now in my bag and fax it tomorrow morning

Anyway so after wat Megadark has say, u still want to attend?

[hong]

wah that's real bad, you may want to bring back your camera for remap again err what is the feature in PS6 you had used previously to clean up the noise?

[Kevin]

Not too sure, if I am free I don't mind to burn 4 hrs to learn the 20% loh.

[Kevin]

Don't know how leh. I just follow the standard instruc tion to reduce pixel size and then the level 6 of compression but the images turn out very clean. The previous 2 two photos have a little noise on the cloud.

The latest one is the worst but I don't know if it due to the fact that the DC is on for a while so the CCD heat up!
