Suppose I have the following class:

class Camera
{
    public Camera(
        double exposure,
        double brightness,
        double contrast,
        RegionOfInterest regionOfInterest)
    {
        this.exposure = exposure;
        this.brightness = brightness;
        this.contrast = contrast;
        this.regionOfInterest = regionOfInterest;
    }

    public void ConfigureAcquisitionFifo(IAcquisitionFifo acquisitionFifo)
    {
        // do stuff to the acquisition FIFO
    }

    readonly double exposure;
    readonly double brightness;
    readonly double contrast;
    readonly RegionOfInterest regionOfInterest;
}

... and a DTO to transport the camera info across a service boundary (WCF), say, for viewing in a WinForms/WPF/Web app:

using System.Runtime.Serialization;

[DataContract]
public class CameraData
{
    [DataMember]
    public double Exposure { get; set; }

    [DataMember]
    public double Brightness { get; set; }

    [DataMember]
    public double Contrast { get; set; }

    [DataMember]
    public RegionOfInterestData RegionOfInterest { get; set; }
}

Now I can add a method to Camera to expose its data:

class Camera
{
    // blah blah

    public CameraData ToData()
    {
        var regionOfInterestData = regionOfInterest.ToData();

        return new CameraData()
        {
            Exposure = exposure,
            Brightness = brightness,
            Contrast = contrast,
            RegionOfInterestData = regionOfInterestData
        };
    }
}

or, I can create a method that requires a special IReporter to be passed in for the Camera to expose its data to. This removes the dependency on the Contracts layer (Camera no longer has to know about CameraData):

class Camera
{
    // beep beep I'm a jeep

    public void ExposeToReporter(IReporter reporter)
    {
        reporter.GetCameraInfo(exposure, brightness, contrast, regionOfInterest);
    }
}

So which should I do? I prefer the second, but it requires the IReporter to have a CameraData field (which gets changed by GetCameraInfo()), which feels weird. Also, if there is any even better solution, please share with me! I'm still an object-oriented newb.
