Now the background thing is really bothering me. Why are there two different colored backgrounds at all? Wasn't Jennifer Shen the one doing the testing on both of these fibers? Wouldn't she have looked at them on the same piece of equipment (microscope, camera, etc.)? Why, then, would the background color of these two photos be any different at all? Makes me suspicious, I tell ya. I mean, she was comparing the way the fibers looked, among other things - if you don't have an equal starting point, how can you tell whether they actually look the same or not? Especially on these fibers that appear to be somewhat translucent.

I don't think it makes a huge difference for the scientists themselves. It's like comparing a dna sample made from 3 yrs ago, to a current sample. The make-up of the fiber sample/dna sample would still be usable regardless of how it's attached to the slide..right?

We may not haev any idea what the orginal's look like. The examiner would have seen orginal's in microscope. Then a photo was taken apparently for example merely for demonsrating the evidence, I believe the Jury will have actual slides available if they desire. Further, assuming we are looking at photos these photos had to be scanned.

In order to say anything definitive about comparing them we have to state the light, background and distance etc was exactly the same AND we have to make the same claim about the scans so we can view them on computer. Plus if they are not direct scans of original photo we may be viewing a press photo of a photo.

But what do I know, I can't match my clothes.
