When I first started at CSIRO in 1974 my immediate supervisor explained to me about this Malin bloke that made out of focus masks to modulate the image on the very large plates from the Anglo Australian Telescope when he 'printed' them to tease out low contrast detail and still attempt to get the full dynamic range. This very bright scientist was Peter Tulloch.
We all think we live in a golden age of discovery. The reality is we should do the best we can with the equipment we have and also realize any shortcomings in ourselves and the equipment.
We should all take a moment to contemplate all the people who came before us that spent their lives showing us the way.
All scientific endeavour depends on so many people and good equipment before we even have a good idea, so it is difficult to excise your original contribution from what is already known.
