important that you specify _B&W_ cameras because 3 years back I bought
a QuickCam from Connectix for this job (this after having read a
Biotechniques article)... For EtBr gel captures, I used an orange filter
sheet that Audio Visual Centers get to select their projector filters...
However, I had purchased a _Color_ camera (more sensitive) and found
out that they can _NOT_ be used for EtBr gels (albeit very strong bands,
such as upper lambda HindIII for instance could be visualized)...
