How To Use Various Netting and Gauze Fabrics in Scenic Design

 

Scenic designers use Netting and Gauze fabrics in combination with other scenery and lighting to create visual illusions and spatial depth.  The transparency of netting and the translucency of gauze make these fabrics particularly well suited for these effects. The following describes the characteristics of various nettings and gauzes and how you might use them to best effect. More...

Projection On Scrim

Here's a response to a customer inquiry that might also be of interest to many others...

Issue: "I am trying to front project on the scrim with a projector that conceals the set behind it with good light control. Please suggest a scrim for me and anything I should be aware of."

Response: Projection onto scrim can be a bit tricky but if you know some of the ins and outs you should be able to avoid the challenges associated with this effect. 

All of our (scrim products) can be used for projection but typically theatrical projection is done on the old standby of white sharkstooth scrim.  I have also seen projection done on elements of painted black scrim and scenic painted scrims.  We have seen many desirable front projection effects and images produced on black scrim that has been sprayed (on the front) with rear-projection Screen Goo, as this makes a great reflective surface for the image on a black substrate.  I personally do a lot of outdoor projection onto vinyl mesh like textilene or speaker mesh with great results.  The scrim material chosen will depend on your application and the desired seamless area.

The effect of a scrim heavily depends on the control of stray light. It uses contrast to fool the eye into thinking that the material is opaque.  Traditional theatrical scenic scrims are typically lit from a very steep angle so that the light that passes through the scrim falls just upstage or in the wings.  As long as the space and objects behind it stay dark, you will not see anything through the scrim.  If there is front light hitting the scrim straight on, or at a shallow angle, it will illuminate the area and objects behind the scrim.  This is true for direct and reflected light from the stage.

When you apply this to projection, things will get a bit more complicated.  The ideal setup will depend very heavily on a number of variables; the effect to be achieved, desired quality and purpose of the projection image itself, and the technical capabilities of the venue.  All of this is assuming front projection on scrim since rear projection is not advisable and is typically done for effect only.

If your primary concern is projection image quality, you will likely want to put the projector in the house straight on to the scrim.  This will produce the best quality of image but is the worst case scenario in terms of making a scrim appear opaque.  This is typically how scrim projection is accomplished but it will likely require a blackout immediately upstage of the scrim.  This blackout will catch all of the projector overshoot and certainly mask the scenery or stage behind it.  Just before the reveal is made through the scrim, the blackout will be flown out or traveled open.  If you are looking for a double image, the blackout may not be necessary at all as the background would be dimly lit the entire time.

If you are looking for less quality of image and more effect, the projector(s) can be placed at a sharp angle to the scrim and blended into one image similar to the way your stage lighting would be.  This requires equipment capable of this type of image warping and will certainly reduce the overall quality of the projected content.  This can be a technically complex setup and will require the appropriate projectors and image processing.

Here is the third article in our series on “How To Light A Scrim.” This article is derived from questions most frequently fielded by our salespeople at Rose Brand.

Does it matter in which direction the “tooth,” or opening in the scrim, is oriented?

The tooth is about twice as high as it is wide, and this is the common orientation when sewing the scrim. The properties of the scrim, however, are not affected if the tooth is rotated. In fact, this may be done to save a user money and more efficiently use the available widths of scrim in stock. 

Another common reason for rotating a scrim is to More...

The most common placement of lighting instruments for a scrim is above and directly in front of the scrim. However, that isn't the only lighting position that will be effective. Remember: angle angle angle! As long as your lighting is oblique, and can wash the scrim, it doesn't have to be from above. If your scrim is in an extreme downstage position, for example, footlights can be very effective for scrim washes. (In this case, the “spill” light is lost up in the flies, behind the proscenium and/or masking borders.) In a “wing and drop” set, More...

One might think that a fabric company has little to do with lighting. After all, while scenery and lighting design are inexorably linked, how important can fabric be to either? Yet the choices a designer makes in fabric, as with all the other elements, will directly affect the final look of the production. This series of articles discusses common types of fabric, why they are used, and challenges they may present to a lighting designer.

ANGLE, ANGLE, ANGLE
Lighting vis-à-vis fabric is nowhere more critical then when dealing with sharkstooth scrim (or simply "scrim" as some refer to it). Lit correctly, a  sharkstooth scrim provides one of the most magical effects: the bleed-through. If the scrim is lit correctly, it can appear completely opaque; as the lighting is changed, the scrim will “dissolve,” allowing the scene behind it to “bleed through” the scrim or the scenery painted on the scrim. Continue the change, and the scrim will disappear completely, as if by magic. But what is the “correct” way More...
