Dreaming of the Beach II
Playing with some tiny shells from Barricane Beach in North Devon as part of Macro Mondays "My Closest" challenge for this week.
This one is 13mm long, and, if photographed straight would have been longer than the sensor is wide. Photographed on sandpaper in natural light with my 100mm macro lens using three extension tubes.
The extension of 68mm adds an extra x0.68 to the 1:1 magnification the lens already gives (increase in magnification=extension distance/lens focal length).
This gives a total magnification of 1.68:1, in practice the best I could obtain from my lenses. (Sensor 22.4mm wide).
My friend Liz and I visited Barricane Beach in 2017.
