TA's left eye . . tell us what we see . . . enhanced to 72 dpi stock from the camera - has to do with printer . . .output format
based on this what can we see? any conclusions from this?
reflection from the cornea - interesting if not in the mid of the pupil - would not get this photo . . . camera being fired from this position . . choratic ?
fairly low . . . can you recognize person taking photo? no there is not enough pixels per inch . . . but someone taking a picture about chest high . . . don't know the height of TA and don't know height of TA so purely speculative.
same image only it has been taken up to 2280 dpi - easier to work with. . .
in clear id . . .on digital camera - notice one white dot - dead pixel . . . go thru and see if there are any bad pixels to blow it up . . . went thru each channel . . . didn't find any dead pixels -
exhibit #3 - admitted for this hearing only
resolution of the monitor . . . in his lab it is 2x the resolution . . .
up resed to 2880 dpi - no bad pixels . . .more latitude working pixel by pixel . . .
someone has a mole could be a dot on their face - from bad pixel - make sure no dead pixels . . didn't look @ entire picture - just part of pupil area. . .
based on this do you begin to see more in this picture?
yes but I was able to trace what I could see in the lab - I did rough outline what I could see in the lab.
then in that outline . . . exhibit #4 purposes of this hearing
same photo with outlines referred to.move to admit #4
admitted for this hearing
witness steps down an changes picture again . . JA looks on and whispers to her Atty
Image on screen looks to be a human figure on his equipment . . .person holding a camera . . . this outline . . . only thing changed was the brightness (light level) . . .
black values drop out first - in order to trace more clearly - he enhanced the brightness -nothing fancy.
too much light on the subject - white values tend to bloom - blown out face and hair
2880 dpi . . . further enhancement make to photo?
cleaner but very good chance I could creating an image vs. enhancing.
if I go any further . . . . I went up to 7000 dpi - didn't see advantage
I did pixel stacking - yes I could see a little more but I don't think it would be good evidence.
