Default Fz150 iA and macro

I especially like the macro mode (on the dial), with this camera, but there's much more noise than with manual, even at the same iso. I have the noise reduction turned down to -2 for manual, but can't do much about it in iA and macro. PIE tells me that NR is 0 for iA and macro, and I suspect that this is why my images are so noisey. Does anyone know of a work around for this, perhaps another setting will dampen the noise, or ???
Thanks,
.... john

Unfortunately, noise is most apparent in out-of-focus (bokeh) portions of an image, and macro means lots of bokeh. You may already be getting the best (or close to it) you can hope for from a small image sensor.

Hi TCav,
Yes, maybe, but the manual closeups are much less noisy than the "macro" closeups, even at the same iso. I guess I'll just have to live with it.
Thanks,

Are you completely sure that the camera is not overriding your ISO setting when you use macro mode? I seem to recall this being the case with some cameras, but not sure which. The Exif info would tell you for sure. It doesn't make much sense, otherwise.

Hi Brian,
Oh yes, I'm quite sure it is overiding my settings. I have little control over any settings when using the on-board macro mode. It pretty much does it's own thing. But when I did the comparison between macro and manual, PIE (Picture Information Extractor) said they were both iso 100. Then I checked what the NR setting was for both modes; and it said -2 for manual and 0 for macro, which to me means that the macro setting would yield noisier images, which it did. It seems to be common knowledge that the native NR setting of 0 produces noisy images, and should be dialed back to -2, which is what I have it set at for manual, but the default, unchangeable NR setting is 0 for macro. I have a suspicion that the noise reduction algorithm (if that's the right term) is the reason for noisier images in the on-board macro.

If you don't mind adding a step (and spending a bit of money), Topaz labs has an excellent noise reduction add-in for most any image editing software which can use the adobe .8bf plug-ins. It works very well at reducing noise while still retaining detail. My Minolta D7hi tends to be quite noisy at anything over ISO 200, and Topaz Denoise really cleans up the images. I think they still offer a 30 day free trial.

G'day mate

You are asking the same sort of Q under several headings - I have chosen to give you a big answer under your " Raynox for FZ150" post

Hope this helps a bit
Phil

Thanks Brian,
I'll consider that.
Hi Phil,
Yes, somehow both my questions ended up at the same point.

Bear in mind that iA/preset macro mode can often increase sharpening- which will exaggerate noise....
