In the back position it’s in full manual mode that overrides the camera body switch.  Focus Aids  Focus  magnifier  (Assign  button 4,  on  the  handle),  push  once  x4,  push  twice  x8,  push  three  times returns to normal.   Peaking adds a coloured edge around objects in focus.  The button  is  on  the  left  hand  side  of  the monitor.  The  colours  can  be  changed  in  the  peaking  by going to   Menu  >  VF  >  Peaking  >  Peaking  Type  >  Select your colour     
						

									October	2016	v4	22	 Focus Aids Continued  Focus Assist indicator         Exposure Tools  You  have  the standard  exposure  tools  of  zebras,  waveform  and  histograms  that  are  all  set  and controlled under the VF page of the menu.  In  custom  mode  everything  is  measure  of  what  you  are  recording.  In  CineEI  the  zebras  measure the view finder image and the waveform a  Zebras Measures the viewfinder LUT on = Measures the MLUT LUT off = Measures S-Log Waveform and Histogram Measures SDI 2 LUT on = Measures the MLUT LUT off = Measures S-Log  Zebras are set in VF menu; zebra 1 default is 70% (Standard for skin tones using 709 gamma) so when exposure reach’s 70% zebras will appear but with the zebra aperture set to to 10% zebras will start to appear between 65% and 75%. Zebra 2 is slightly different to zebra 1 where it looks at the over exposure so when it is set to 100% it will come on and stay on for anything 100% and above. This can be changed in the VF settings in the menu.       Frame	your	object	you	want	in	focus	inside	or	near	the	white	box		As	the	shot	comes	into	focus	the	graph	will	start	to	fill	from	the	right	but	will	never	go	all	the	way.

									October	2016	v4	23	  Exposure Tools Continued  See that Zebra 1 the lines are \\\\\\\\ highest point on the left and lowest on the right.  See that Zebra 2 the lines are //////// highest point on the right and lowest on the left.   White clip default setting is 105% so the camera can record anything above 100%, so having zebra 2 set to 100% it indicates that last bit of range you have available when using the standard rec709 gamma.  It  is  recommended  that  when  you  are  using  hyper  gamma  1  or  2  that  you  set  zebra  2  to 90/95%. When  using  CineEI  zebras  measure  the  MLUT  output,  if  you  use  the  rec709  MLUT  then normal zebra levels should be used (Zebra 1 = 70% and Zebra 2 = 100%).     
						

									October	2016	v4	24	  Histograms  Histograms measure blacks on the left, whites on the right and the height shows the level. A good image has an even spread with a bump in the middle for skin tones. To turn on the histograms, it is in the VF menu under displays on/off.           
						

									October	2016	v4	25	Histograms continued   Waveforms  To turn on the waveform, it is in the VF menu under displays on/off. This is important to have shown specially when using hyper gammas (Page 12) to expose middle grey at the correct level.        
						

									October	2016	v4	26	Below are examples of where highlights, shadows and skin tones should fall within the waveform using rec709 gamma.

									October	2016	v4	28	Slow and Quick Motion  Slow and quick motion (S&Q) increases the recording frame rate of the camera. Standard frame rate is 25 frames per second (FPS). This only works in progressive. The camera must in using the XAVC-I codec and the maximum frame rate is 150fps. Press the S&Q button on the left hand side of the camera to enable S&Q mode. Once S&Q is active it defaults to 60FPMenu > Recording > S&Q Motion To get beyond 60FPS you must go to high frame rate and activate full scan then you can change the frame rate.   This	indicates	that	S&Q	has	been	activated	on	the	right	you	see	60FPS	 
						

									October	2016	v4	29	 ND Filters  There is a silver dial on the front left that controls the ND filters with the options of clear, ¼ = 2 stops, 1/16 = 4 stops and 1/64 = 6 stops.  What is a stop using ISO? Doubling the ISO number gives an increase of 1 stop, while halving gives it a decrease of 1 stop.  What is a stop using aperture? Because of the way f-numbers are calculated, a stop doesn't relate to a doubling or halving of the value, but to a multiplying or dividing by 1.41 (the square root of 2). For example, going from f/2.8 to f/4 is a decrease of 1 stop because 4 = 2.8 * 1.41. Changing from f/16 to f/11 is an increase of 1 stop because 11 = 16 / 1.41.  Below shows what everything is doing inside the camera and lens     
						

									October	2016	v4	30	 Gain Gain  is  an  electronic  amplification  of the  video  signal. This  means  that  the  signal  is  boosted electronically, adding more voltage to the pixels on your imager (CCD or CMOS) causing them to get amplify their intensity and therefore brighten your image.   Gain is measured in db with the following values and what they mean in terms of how many stops of light do they add  L +6dB = Adds 1 F Stop  M +12dB = Adds 2 F Stops  H +18dB = Adds 3 F Stops  On the left hand side there is a switch that has 3 positions (L,M,H). These values can be changed by going to  Menu > Camera > ISO/Gain/EI > You will see the options to change low, medium and high                 Gain	Switch	Shutter	Speed
