Channel.md

+# Channel
+
+
+There must be one per channel in the Image, even for a single-plane image.
+And information about how each of them was acquired is stored in the various optional Ref elements.  Each Logical Channel is composed of one or more
+ChannelComponents.  
+
+![](./media/ome_xsd_Element_Channel.png)
+
+For example, an entire spectrum in an FTIR experiment may be stored in a single Logical Channel with each discrete wavenumber of the spectrum
+constituting a ChannelComponent of the FTIR Logical Channel.  An RGB image where the Red, Green and Blue components do not reflect discrete probes but are
+instead the output of a color camera would be treated similarly - one Logical channel with three ChannelComponents in this case.
+The total number of ChannelComponents for a set of pixels must equal SizeC.
+The IlluminationType attribute is a string enumeration which may be set to 'Transmitted', 'Epifluorescence', 'Oblique', or 'NonLinear'.
+The user interface logic for labeling a given channel for the user should use the first existing attribute in the following sequence:
+Name -> Fluor -> EmissionWavelength -> ChannelComponent/Index.

Filter.md

+#Filter
+
+A filter is either an excitation or emission filters.
+There should be one filter element specified per wavelength in the image.
+The channel number associated with a filter set is specified in Channel.

+
+It is based on the FilterSpec type, so has the required attributes Manufacturer, Model, and LotNumber.
+It may also contain a Type attribute which may be set to
+'LongPass', 'ShortPass', 'BandPass', 'MultiPass',
+'Dichroic', 'NeutralDensity', 'Tuneable' or 'Other'.
+It can be associated with an optional FilterWheel - Note: this is not the same as a FilterSet
