We were comparing the results of drum scans with digital camera reproductions of 35mm film using a high quality macro lens and the highest resolution cameras available. The drum scans were not only at least as sharp as the digital camera results but, more importantly, were substantially better in terms of tonality and colour accuracy.
Tim and Charlotte provide a thoroughly professional and very high-quality service and I cannot recommend them too highly.
I have to say that I have been blown away by the quality of the drum scans that Tim has produced for me. Working from difficult negatives he has made drum scans that amazed me and the printers I work with.
