|The signer should feel comfortable with his/her lines as well as with the camera (and the cameraperson!) to be able to sign with confidence and conviction, from the heart. For many productions the preferred set-up is for the signer to directly address the camera.
A signer can sit or stand; if s/he is to walk around, movements should be carefully choreographed, to allow the cameraperson to shoot the scene without losing track of the signer or the sign language. The signer will usually sign a text in short segments or paragraphs, of a size that can be memorise and reproduced at a time.
A sign language monitor or consultant should be available during the filming, to cue the signer and to check the sign language. A cueing system (autocuer, cuecards, etc.) can be used, but should not interfere with the fluency and the power of the signer and the sign language. If more than one signer is to be filmed simultaneously, use of space and interactivity should be carefully choreographed, and the visibility of all signers monitored.
For many productions, it is important that the signer signs a text, exactly as it was decided on by the translator/text-writer team. At the same time, the signer should seem to be signing 'from the heart': the signing must seem natural and spontaneous. A viewer will notice it when the signer is trying hard to remember what comes next, but also when a signed text has been 'overlearned', and is being signed 'by rote'.
Some signers can memorise all their lines and sign an entire story or text at a time. This is most likely when the signer is quite free in his/her use of sign language, e.g. in the case of an original sign language story.
When the signer has to follow a script quite closely, most signers sign the text in short paragraphs, or sections. After a paragraph has been filmed, the next paragraph can be rehearsed, and recorded. If fairly short shots are later to be pasted into longer shots, the beginning and ending position of the signer should be the same in successive shots (e.g.: the signer begins and ends each shot in a neutral position, or begins each shot in the ending position of the previous shot).
If a text is too long, or too complicated to be memorised, the signer can use a cueing system. Experienced signers use different cueing systems:
Signers can sit, stand, or walk around while they sign their lines. What is most appropriate, will depend on the script and the personal preferences of the signer(s). If a signer is to be superimposed on a video, the signer is usually filmed standing up, in a fixed position.
Signers who walk around will have to follow a script, so that the camera-person will know exactly what to shoot, where to focus the camera, etc..
If there is only one signer, most viewers prefer the signer to sign directly to the camera - pretending that the camera / the viewer is the communication partner. With two signers in dialogue, many viewers still prefer the signers to address the camera, instead of each other.
Interaction with visuals and props - or even with the viewer - is appreciated by viewers: this can be done by means of body-position, eye-gaze, localisation, pointing, showing, etc.
Most signers can use various 'registers', or 'styles' when signing: e.g. a 'high, abstract' style, versus a 'concrete, more iconic' style, serious or humorous, for children or for adults, highly expressive or neutral. Signers should sign in a register (signing speed, style, expressiveness) that matches the content of the video and the target group. If a signer is signing a story with several characters, each character should have it's own register, so viewers will be able to identify the character.
If a video is to be recorded in more than one session, there shouldn't be any major changes in the signer's register between sessions - unless of course this is required by the script.
Since there is no real interactivity with the viewer, and since the signer has no way of knowing how well viewers understand what is being signed, signers should sign slightly more slowly in front of the camera, than they would do in an interactive situation; and for some productions / target groups: much more slowly.
If the signer is to be superimposed over a mainstream video or TV-programme, the signer should synchronise his/her signing with the actors and actions in the main screen.
Viewers who are not experienced sign language users (e.g. children, or Deaf people who have learned sign language at a later age) prefer a signer who signs very clearly, directly to the camera, in fairly predictable shots. Their main request is that the signers sign in a way that is easy to understand. In countries where Deaf people have access to a lot of TV- and video-programmes in sign language, viewers may find this way of signing to be too predictable, and therefore: boring. They may prefer a faster pace, more varied signing, more gimmicks: less emphasis on the signer being easy to understand, more emphasis on visual interest and pace.
During the filming, the signer must be assisted by a sign language monitor or consultant - preferably a native signer - who knows the target group and the production's subject well. The sign language monitor checks the sign language used by the signer for format and content, and is often the intermediary between the signer and the camera- and other technical persons.
When a shot meets the criteria, the scene, shot and take-number are entered in the production log, together with the beginning and ending time codes. The signer will then practice the next paragraph, sign it in front of the camera, etc.
For the Signing Books user tests with children in the Netherlands, a translation into the Sign Language of the Netherlands (SLN) was needed of Hans im Glück, a German sign language production for Deaf children. The signed text of the German video was first translated into printed Dutch. Then, the printed Dutch was translated into SLN by a Deaf/hearing team. The German sign language was used during the translation process, for support (some sentences and paragraphs were easier to understand in German sign language, than in printed Dutch), for inspiration and for comparison. The text was then signed in front of the camera by the hearing native signer, with the Deaf team member acting as sign language monitor and shadow-signer. Since there wasn't enough time for the signer to learn the text by heart, it was decided to use an audio-tape during the filming, to cue the signer. The tape was a recording of the signer reading the Dutch text. The tape proved helpful - because fairly long shots could be recorded in one take, and the entire story (20 minutes of signing) could be recorded in half a day. It was, however, an emergency measure. The audiotape influenced the signers role which became that of an interpreter, instead of that of a story-teller. In some instances the audio-tape interfered with the signer's pace and concentration.
