Not completely happy with my first try, I have decided di make a further step by scanning my old 6×7 negative with a digital camera. I have used an old 10 Megapixels Canon EOS 40D with a Tamron SP 90mm AF Macro lens. After few tests with different magnifier factor, I have decided to take 2×4 shots, this allowed to have at least one side of the negative frame in every shot, making the work of merging much easier. The resulting 56.3 Megapixels image is the sum of 8 shots successively merged in Photoshop. The image has been resized to 1000px because is pointless to have bigger images for web publishing purposes as very probably few of us have monitors with vertical resolution higher than 1440px.
