Added Chaff Noise

There is obviously a difference, though it varies.

In the bottom two examples, it seems to have added some detail, but in the top example, it seems less detailed, so I'm not sure what to say on that aspect.

The one difference which seems to be fairly constant in all three samples, is that the addition of the chaffs seems to have created more depth to the relief, though that varies slightly also.

I think both are very attractive effects, and quite similar, so I would really think it is all a matter of individual taste or opinion.

My own preference leans to your original, but again... just one person's opinion.
