size determination of rflps

[Ola]

Hi! Does anyone know a system for size determination of RFLP fragments? We're 
now measuring the fragments manually from polaroiod photos and converting them 
to baspair lengths. We would like to speed up the process and use a scanner 
(with polaroid photos, or without using a video camera or similar) and some 
clever hard and software that does the calculations. We are greatful any kind of 
advice! Thanks in advance, Ola Kaaren
