DrawImage colors too dark.

[aewarnick]

When I draw an image the color is not the same as the original. Is there any way to fix that?
e.Graphics.DrawImage(Im, rect);

I found that if I use DrawImageUnscaled I get perfect quality.
Now, the question is,

How can I use DrawImage and get the same image quality?

Even when I include:
e.Graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
in my paint event, the quality is better but not near as good as Unscaled.
