No it definitely sounds long.
9 seconds to find camerra
1 second to turn on
X seconds to select exposure, though if not on microscope, then it is automatic.
<10 seconds to capture and download-interface is fast SCSI(20 MBits/sec).
For us, compression is always off. Do not forget that the DC120 is
designed as a consumer product rather than a professional product. For
just gel documentation, we use a digital capture on the Alpha Innatech
system. Has filters so that we can do EtBr gels. It works out to about
10 cents per image to print out.
