Sunsets and noise associated - DPChallenge Forums

I've had to retouch this photo, f2.0 ss 8 secs with ISO 400.
Is it the ISO that has caused the noise? I've looked at previous evening shots that were at ISO auto not forced 400 and they are clear.

BTW- Sony CD Mavica CD500, Carl Zeiss Vario-Sonnar lens

Thanks.

On my camera, if I set the ISO to 400 (the highest), the pictures come out with tons of noise. I was messing around a few nights ago taking pictures of Mars, and although a lot dimmer, the shots with lower ISO turned out a lot better than when I had ISO cranked.

Edit- Aside from the noise, I like that shot a lot. Good composition, light, and colors.

That's what I associated it with so its good to hear of similar experiences. This is a great forum.

Here are some other photos with better results, yet I'll just post the link to speed up the time to load this thread....

Those are some nice shots. I think the noise is more evident the darker the pictures are. I noticed a lot less noise in this list than that first picture, and the one taken in daylight of the horse and carriage looked very clean in comparison.

I have the CD400, and I've noticed quite a bit of noise at ISO 400. If there is any doubt, I always use a tripod and ISO 100. Then the grain virtually disappears.

I'm glad to see another CD Mavica user on here - we are scarce.

Hey Steve,

It is very nice to meet another CD Mavica user! I bought my CD500 in July and it spurred a friend to buy the exact same camera yet he's got no idea what f-stop is! He and his wife were up at the cottage a week ago and that's where these photos were taken.

I still use my SLR yet for B&W opportunities only now as I am totally hooked on the digi platform. I expect to be moving to a DSLR in 2-3 yrs when they drop to <$1k so that I can use my SLR lenses.

Thanks for your observations on the ISO400 settings, it solidifies my conclusion and is greatly appreciated. BTW, all of those photos were obtained with a tripod with the exception of the photo of the horse & buggy; it was taken from my van at a stop light as the couple passed by and just turned out right. :p

Cheers.

Maybe not, yet in 1998 I was at the Toronto Stock Exchange for a corp. launch and the guy that was being paid to cover our event advised me that his DSLR cost $32k. In the mean time I'll certainly enjoy the CD500.

Point is that I'll bet he never recovered his initial investment!

I've been waiting in the bushes for the price to drop and with the birth of our third child I decided to take the plunge with the CD500. Looking back over the past four months I've captured a remarkable change and that in its self is worth every penny for the cost of the digicam.

This is a great forum to refine my skills and gain insight into new frontiers. Does the host accept PayPal donations to keep it running?
