it's always kinda nice to use similar pictures to other reviews when possible simply because it just provides another reference point though one shouldn't put too much stock in that.
art over at projectorreviews.com does a pretty good job of being consistent in all of his most recent reviews (within the last 18 months) and tries each of the PJ's he looks at on 3 or 4 different screens with a firehawk being his reference screen. he also provides a brief recommendation as to which screen color he believes will be most appropriate for a given PJ.
i'm probably stating the obvious but i'm going to guess that all the screen shots will be done with your HC3000 projecting the image and if this is the case here is art's review of your PJ and the array of screenies he provided for reference

)
since you will be trying varying shades or gray between N8 and N9 plus hopefully being able to get a good look at bill's creation it will be interesting to see how your results compare to what art found

i just like that fact that most every screen shot i've seen posted here thus far has always been of something with a little challenge to it rather than the typical "look how good monster's inc." or "finding nemo" looks on my pj.
