Did you tell them what you used or did they ask?

To Pat

I took a bunch of "noise" shots just before I sold my G3, and I wondered what the best thing to
photograph was. I wanted a plain white sky, but knowing my luck the sun came out so I had to make do
with a blue sky. Any idea if this makes much difference?

Considering that noise is supposed to increase at longer shutter speeds, I took shots at many
different shutter speeds. Does this make much difference in your opinion?

What Neat Image settings are you using? Full noise reduction or what?

No, I didn't - they do not specify that CF *must* be used, only something like "similar professional
software". Being as I had to pay for it, I call the FM action "professional software"! Also, my D30
only produces 9MB 8-bit files, instead of the 14MB that they specify, so I sent off the test CD to
see what happened, and they accepted it.

I don't think so - the noise in the sky doesn't seem to vary much whether it is blue or a
hazy white.

My workflow is as follows :

(a) Download images from the camera using Breeze's Downloader. Delete obvious duff photos.

(b) Use Breezebrowser to convert the RAW files into 16 bit tiffs in a TIFF folder inside the month's
RAW folder.

(c) Copy all the files into Neat Image's queue.

(d) Go down the queue setting the appropriate noise profile based on the ISO setting for
each picture.

(e) Run the batch and go and do something else for a few hours.

The noise reduction setting is therefore the default. This is what I do for everything, but if I
have something special, then I would work out what the best noise reduction settings were for that
image, maybe even re-doing the noise profile for that image. I haven't done many long exposure
images for a while, so I have not looked at the effect of shutter speed on noise. I suspect that you
would need another profile for each ISO if shutter speed is into seconds.

Best wishes, Pat
