    Monitors, and Diving

    Community Member

      ============

      Well, if you use Reference Monitor for current clip, you may try the following:

      - use Program Monitor for the scopes and Multi-Camera Monitor for Composite video;

      - use Source Monitor and Reference Monitor for viewing previous and next clips...

      ==========

      that sounds interesting. never used multi camera thing except in some tutorial and never tried cc in that mode.

       

      but, it makes sense that reference can show you current timeline ( albeit delayed sorta ), program for current scopes of targeted clips, and source for comparing the original col space with matching them ( again, using memory in your head and matching ..but now with scopes ( data ) and reference ( look ) to help you.

       

      I think I have to be in the same room as you to see this clearly.. and judging by the diving stuff it's unlikely even then I would be much help. Last time I went diving I used all my air in half the time everyone else did... and thought I was on mars after about 10 minutes... the drifting weeds kinda mesmorized me...

            anyway.. interesting thread.. thanks for sharing.

             

            im just curious.. as I'm in ny area and water is not so clear usually.. you got a light that looks like a diffused wide source on left of this frame, and there's light coming from another source frame right.. ( maybe also high ).. and not much junk in water to impair vision...

            from the " camera" point of view of this shot... it looks like you have a planned dive for " shooting" ( recording) the dive ...in pretty clear water... is this a training excercise ?

              Being honest, that was the dive in quite muddy water of local lake. The visibility was just about 3 meters.

              The images above are an example of draft playing with curves, 'cos I used completely wrong filter there, and original shot looks something like this:

              For me it was testing my new camera housing.

              For the girl in the shot - part of her diving course...

                now that shot looks like some kinda kino flo ( flourescent )lighting with soft diffusion at 56k cam. setting when light was more like not even 32k...what you would normaly put minus green and other gels on light to make balanced ?.. anyway.. color meter and gels on lights fix that stuff. see roscoe and lee cc color stuff online.

                 

                thats a GIRL ?? !!!!

                 

                is she married ?

                 

                just kidding.

                 

                love adventurous girls .. we have to move this to lounge now.. cause I have no technical expertise to help with color stuff and monitors etc to shoot " lake placid 2 "

                  No, she is not married! Should I ask her about you?

                   

                  Regard to balancing white underwater, I use to dive in 'blue' tropical waters and normally utilise lights with colour temperature of 6500K plus orange filter to compensate loss of red after 5m depth. I'm not experienced in diving in 'green' waters like the one in our local lake, where that shot was taken (that was the only time in 2009 while I was testing the housing). Rumors and gossips say u/w cameramen should exploit magenta filters in such conditions... Not sure I'm going to check whether it is correct or not... I don't like cold and mud...

                    she would just laugh... at one tooth dragon...no... better leave it be...

                     

                     

                     

                    funny.. I just turned on puter and saw this moved to lounge, went to a different mssg, and presto ! you added another post.  Good timing.

                     

                    This underwater stuff is pretty interesting cc wise...I wonder, do you have a color meter ? what if you took one down in plastic bag or something and checked color at depth, and did as much cc as possible at your lens...

                    Then you could 'match' your light sources with rosco or lee gels too...so you have whatever color temp you want for white bal..

                    we use plus and minus green ( for flourescents ) and there's gotta be some stuff that rosco and lee make for underwater stuff... ( will check their website ).. if there's a common shift in various water ( fresh, salt etc ?? ).

                     

                    pretty interesting stuff... you can get cc swatches for free from rosco and lee by the way.. just tell em you work as a shooter and they will mail nice swatches... you can basically ( if this ever becomes something to pursue ) just use color meter at depth... with lights ( since you know their temp can adjust as needed at depth ).. then use a color corr swatch ( or combination ) taped to sensor of color meter, go back down and check that its now OK for your camera film color temp or digital temp setting for white bal...then use THAT cc that was on meter on your lens.. ???

                      hmmm, just called rosco labs ( in CT ) and spoke to person.. and the answer is, " NO " , they dont have any underwater stuff ( nor have they tested for this ) as per salinity and depth and so on .. and suggested basically what I suggested re: color meter, put on cc to meter and then check...

                       

                      these are the gels... and you can order free swatches on this page.. the swatches are about 5" long and 2 " wide approx.. and you can basically just cut out the ones you want to tape onto meter..

                       

                      http://www.rosco.com/us/cinegel/index.cfm

                       

                      hehe.. never really thought about how it would be to be like a DP underwater, but if I used my air twice as fast as everyone else just doing NOTHING.. I imagine the stress of lighting and cc and getting stops right for key, fill and back lights would make me use my air about 20x faster... I would need about 400lb air tanks on me to work 30 minutes....???

                        one more thing re: cc between meter and gels...

                         

                        for some weird reason ( nobody knows ) the cc on back of color meters is NOT cross referenced with motion picture ( and tv ) color gels.. I was at a seminar with tiffen, rosco and some dir. of photography, where some new arri lights ( flourscents like kino flo ) were being introduced... and some cc issues were discussed... and nobody knows why the stuff isnt cross referenced... but in general ( a rough start anyway ) is this ( sorta done by trial and error by people on jobs )

                         

                        color-correction.jpg

                         

                        so , that basically applies to CTO and CTB  ( eg. full = full cto, ctb , 1/8 = 1/8 cto, ctb )  its the plus or minus number followed by the film gel equiv....at either full, half, quarter , eigth....

                        I tried it out and its pretty close

                         

                        For YOU, you would also need to check your LB for green etc ... and we usually use a magenta looking gel called minus green for that correction on flourescents that arent bal for 32 or 56k...

                         

                        you can ask rosco for sample " sheets" of individual color corrections and they will mail free too...they are nice.

                          Hm-m-m, some interesting points... Thanks!

                          ...I imagine the stress...

                          Well, first time you bring your camera underwater, your breath really increases dramatically. By the time you get accustomed to, however...

                            " get used to it "

                             

                            Not me.. my being in water days are extremely limited. My only scuba dive was a lake upstate ny and I didnt really like it very much.  Mask kept fogging up, couldnt blow up my stupid vest well ( to stay on surface when I wanted to ) and used air too fast... and got dizzy looking at weeds ( felt like I was on some acid trip or something ).

                             

                            I was slightly better at snorkeling... at least once I figured out how to blow water out of the silly snorkel near surface, and get some air to go back down, and not inhale a bunch of water by accident.

                             

                            Anyway, Im sorta not keen on breathing through tubes and stuff cause I had asthma as a kid ( born with it ) and half my kiddie life I was petrified of dying via lack of oxygen... cause I WAS... being underwater sort of reminds of that creepy stuff.

                             

                            I started smoking cigarettes to get over the asthma, if you can believe THAT.

                             

                            Anyway, lighting and shooting in this big pool for this movie ( worse movie ever made I was key grip on ) was the only close experience I had of what you're doing.. and I have to admit what you are doing is way more challenging.

                             

                            And being fresh water in pool cc wasnt really an issue..

                             

                            Movie is so bad nobody would notice cc anyway !

                              Not me...

                              Actually, it highly depends on instructor... I don't much like PADI (which stands for Put Another Dollar In actually) instructors. Some years ago I was lucky to meet quite good tech instructor, who tought me everything about controlling buoyancy and operating fins. I never regret I threw out my newly bought Aqualung BCD and Mares Avanti Quattro fins and replaced them with Hogarth harness, tech wing and SlipStream fins. Now I can boast I can slide underwater not just forward and backward, but also left and right with just my fins and without any fancy gear...

                              However, I'm not sure I want to move further to become tech diver...

                              Movie is so bad nobody would notice cc anyway !

                              I will! Gonna watch!

                              And being fresh water in pool cc wasnt really an issue..

                              The most embarrassing experience I ever had was my u/w shooting in a pool for local TV show... Although it was mostly because of lack of planning and preparation at all - I was lucky I managed to assemble my diving gear in time, sweating - all the mistakes were mine... Never give you a link to have a look at...
