Edge blend color & gamma questions



  • We suspected that was the case. For my understanding, is it a global adjustment based on the projectors nature or a scene to scene content based adjustment?



  • ....i have good experience -> first doing the colour adjustment of all the projectors which are in the setup -they all should have the same white, red, green, blue... than also the colours of the content on both sides of each softedge should be the same and this is a good base for the softedge - the result also depends from the surface or screen -there are screens out wich have good light division and are especialy developed for softedge...



  • With Bodo on this one, that's what I tried to say in a very abbreviated manner ;) of course there are also other software packages out there and hardware based solutions. The edge blend and colour matching your projectors should be regarded as 'calibrating your screen'; you create one big seamless screen. Once that has been set up properly, it's content-independent (there, I think I just made up a new word!)



  • thanks guys. its 19 projectors in this case so lots of fidgeting to look forward to... my dream is to do it all over pjLink but I am not having much success with that. but that is another thread.



  • Which brand of projector are you using? Never had any problems with Panasonics and PJLink. Happy to help if I can



  • hey fubbi - do you use the soft edge of the projector? - i have always good results with the build in edge blending tool of panasonic...

    Should this be in the pro section @fubbi?



  • @skulpture I checked with Mark before posting. No :)

    @bodo the built in softedge is kind of useless with the amount of distortion and mapping we have.

  • Tech Staff

    Cool just checking @fubbi :)



  • @fubbi: i just used it on a curved screen where i had a lot of distortion - as long as you have a strait horizontal or vertical line after the warping / mapping you can use it -because you can say on which horitontal or vertical pixel (on the projector panel) the softedge starts...in case you have angular lines - yes - it is useless...
