Daffodils – infrared

Trying out a new toy – Hoya R72 infrared filter. Tricky thing because it’s basically impossible to focus or compose with it on the lens so you have to do that, then screw it on, then hope you haven’t messed up the focus too much. So to make sure I stop down to f/8 or even f/11 and use 2 minute exposures. Because of the deep red colour of the filter I use a custom white balance to avoid a magenta morass.
