Projection Screen tests…

I took some pictures of the projector projecting on 3 different types of materials. I’m using a Casio XJ-S30 Projector which has 2000 lumens and 1800:1 contrast.


The following images consist of Rosco Grey Projection Screen (left), tracing paper (middle), and Rosco Black Projection Screen (right).

Here’s one picture with the lights on with Rosco Black (left), and Rosco Grey (right). In the picture the Rosco Black may look slightly better, but in person the Rosco Grey is the clear winner.

It’s really hard to get an accurate picture of what these projections look like in person. The camera seems to make white areas look washed out when really they are clear and bright. In person, the tracing paper has the best brightness and clarity. The Rosco Grey also has nice brightness and overall clarity, but the tracing paper is slightly better (in person). The Rosco Black seems to dull the colors too much. Maybe a brighter projector would bring out the best in the Rosco Black, but with my tests it’s just not an option for use.

The winner in viewing tests:

  1. Tracing Paper
  2. Rosco Grey
  3. Rosco Black

Conclusion:

The tracing paper only has a slight advantage and since Rosco projection screens have the bonus of blocking outside infrared light, the Rosco Grey is the best option and therefore Rosco Grey will be what I’m using (for now at least).

    did you consider the Lee ND filter used by tim roth?

    Hi joe,

    I did consider the Lee frost filter, but found a screen that blocks ambient IR is a better choice for FTIR. Tim uses the Lee Frost on his DI table. I may be adding in DI later though so I might try some of the Lee filter as a projection screen then. The benefit of the Rosco is that it blocks outside IR light so it’s better to use something like that for an FTIR screen.

  • dood.. this blog rules… keep up the great documentation… table is looking great

    Seth, I have been using Vellum since I first started building my table and have been very happy with the performance. It is pretty much the same as tracing paper from my understanding. I have ordered all of the Roscos discussed on NUIGROUP.com just for testing and confirmation.

    Thanks for a gr8 blog and some very helpful info. I was not aware that Rosco blocked outside IR.

    Glad the blog could help you jsearles 🙂

    i have used a projector, and finally made the screen for the DI table. But, the projectors light is blocking the cameras views. So am not getting the desired output. What must be the reason?

  • Hey Seth, 

    When you bought your tracing paper did you look for any specifics? There’s all sorts of different GSM papers and then there’s others which range in thickness by microns, what sort of paper did you try here?

    Cheers 🙂

    • The tracing paper I tested was old and without the box. So, I don’t have information on what grade it was. If you’re able to find some in 1-sheet it’d be cheap enough to buy and try a few. You can find more information on projection materials on nuigroup as well: http://nuigroup.com/forums
