3. Do (1) with another image from another camera/scanner of the same model shot/scanned in
similar conditions; then additionally fine-tune the profile using the input image;
4. Get a ready-made profile built with a similar image from another camera/scanner of the same
model; then additionally fine-tune the profile using the input image;
5. Do (1) starting with a smaller (60x60+) uniform featureless area in the input image;
6. Cut out a 59x59- uniform featureless area from the input image and (preferably) seamlessly clone
it in an image editor to produce a 60x60+ area; do (1) with the resulting larger area;
7. Up-size your image (using your favorite method) in an image editor; do (1) with it; process the
upsized image in Neat Image (do not process original image with such a profile); down-size the
result in the image editor.
5.4. Preparing a set of profiles for different device modes
Since every imaging device can work in different modes, there should be several device noise profiles,
corresponding to a set of modes to make possible processing of arbitrary images produced by specific
device. If the set of profiles covers all modes of the device then any image from this device can be
processed by using one of the profiles from the set.
A set of profiles for specific device should be prepared first. This can be done by any owner of specific
imaging device because he/she has direct access to its hardware. You can do this too. To help you, we
give some guidelines about structuring and documenting sets of profiles so that you could prepare a set
of profiles for your camera, scanner, etc., in such a way as to make use of this set easy for you

.
5.4.1. Structuring profile set
When you prepare a set of profiles, for example, for a digital camera, you build profiles for camera
modes with different ISO rates, quality (camera JPEG compression level), image size, etc. It is advised
to put the description of the device mode into the profile comments fields (Device name, Device mode)
but it is also smart to name the profile file using the key parameters of the device mode. For example,
the profiles for Olympus C5050Z can be named like the following

Here and below, when additional fine-tuning is applied using the input image, the equalizer values should not change
much if the two images were indeed shot/scanned in similar device modes. If the equalizer values do change a lot,
consider doing (1) with another image that is closer to the input image.

..and other people if you decide to share your results. Please do share because in this way you will help people with the
same camera or scanner brand. You can submit a set of profiles to Neat Image team to publish the set on
www.neatimage.com (see Contacts, page 48) or just share them with other people directly.
