#Ultrascope vs scopebox manual
The manual has said that since the beginning, when the fleshtone line was not there.
Marc, I asked for 100% confirmation and you're just regurgitating what was already said in the thread. The top quarter of this line, which runs from about the eleven o’clock position to about the five o’clock position, is widely accepted as the line where skin tones should fall. This makes sense because skin tones are slightly reddish, slightly yellowish and the -I line (sometimes called the “flesh tone line”) is between the red and yellow targets on the vectorscope. Tektronix has an interesting tech paper titled "A Guide to Using Waveform Monitors as Artistic Tools in Color Grading," and it goes into this in detail:ĭespite racial color differences in skin tones, the trace of a skin tone will end up very close to the -I line on an SDI/Composite vectorscope graticule (within 10 or 20 degrees). As far as I know, it's only coincidental that it's pretty close to caucasian skintone. My joke is, "if this $995 product could only do everything the $30,000 Tektronix scope could do, I'd be satisfied."īTW, whenever I used to refer to this as the "skintone line," our staff engineers would slap me in the back of the head and remind me it was actually the I Bar line (as in I&Q) in SMPTE color bars.
So far, Blackmagic has resisted this suggestion. I'd buy one in a second if they would just add a 5X magnify mode to the Vectorscope.
