    Dear Capture team,

    Whether is it possible in the future to make a more realistic view of the light beam for PAR lamps with two angles of light as they do in fact? As it is now, you can see only one angle witch look like cone angle instead elliptic cone. For example Osram bulbs CP60 has beam angle 9x12 degrees, CP61 has 10x14 and CP62 has 11x24 degrees. Of course many different manufacturers made little different angles for same type of PAR bulbs. But these three Osram bulbs are most in use in European theatres and entertainment productions. Would be nice also to have possibility of rotation lamp in PAR house as you can do with real one. Last year we bought Atlas educational release and we start to work with our students. They are very satisfied with possibilities of use Atlas to visualize their lighting exercises and exams.

    Thanks’ a lot, greetings from Academy for drama arts Zagreb, Croatia.

    It is on our to do list to provide better handling of Par lamps. Please stay tuned to our future updates/upgrades.

    But how close to the top is it?

    People have been asking about this since the capture polar days to my knowledge and probably before!

    Hi,

    Our todo-list isn't really a perfectly ordered list of items that we process top-down. At the moment we cannot say when this will be resolved.

    I found a very usefull simple workaround for that matter. There is a external Gobo-Rotator from Rosco in the library, which fits on a PAR-Can, then you can draw your own form for the PAR-Beam and create a custom Gobo with it. I just photoshoped a few beams, I didn't have enough time to take a photo of a real PAR-Beam which could be a perfect template to photoshop a realistic looking PAR-Beam, but this is a very good solution for now.

    I have some samples and screenshots for you and even a capture file to work with.

    and the goboimages:

    And the Capturefile here: PAR_Oval.c2p

    Just play with this idea and improve it, maybe somebody can post another solution.

    All the best Marco

    Hey Marco,

    Neat trick!

    I found there's a slightly easier way, using your rotator method, to get that WFL PAR beam look without having to use a graphics program.


    Once the revo rotator is placed in the PAR-Can, look up Beam Shaper in the Library, and place the first from the list into the Frame List of the Revo Rotator.

    Here's a side-by-side comparison Both fixtures are Altman Par64s with Q1000 WFL lamps. The left fixture has nothing loaded into it, and the right fixture has the Revo Rotator with the Beam Shaper gobo.



    It does the job, but the paperwork of the plot starts to get cluttered showing the rotator.

    I hope that in the future we'll be able to adjust and show the orientation of the PAR in live/plot view.

    Best,

    Johnny

    Thanks Johnny,

    I didn't know about the beamshaper but actually the beam-angles of in Capture are a little bit smaller than they are in reality, the beamshaper shrinks the beam extreme, so it makes a WFL looking like a NSP. I did 4 custom Gobos with the correct side ratio from the OSRAM website, which use the full beam-angle and just cut two sides, so the actual beam-size stays the same but its oval.

    here my beam-shape-gobos:

    VNSP:

    NSP:

    MFL:

    WFL:

    Feel free to use them ;-)

    All the best Marco

    Hi Marco,

    I agree. The stock beamshaper gobo does cut off too much light. These gobos you've posted are dynamite! Thanks so much for sharing! I'll be dropping in the WFL into the plot today.

    Oh...I've figured how to go about hiding the rotator symbol from the plot.
    If you make the rotator its own layer and exclude that layer from the layer sets used in the plot, it will be hidden. Thought I'd share this little tidbit with you or other users who may be going through the same thing.

    Best,
    Johnny
