Point taken, I'm definitely saving my money looking at those on flickr, they're about as good as I'd expect with any lens.
Just used fresnel lens on flashes, F16 or 22, think 1 and 2 were one flash at half power and worm shot was 2 flashes half power., just varied the distance a bit.
Next time I have a go I'll be better prepared with a plastic ground sheet, I was really keen to get started but came in with soaking wet muddy knees.
Off to my dads a bit later, I'll let him see these to show him what his old 1970's lens can do!
Quck question- Do you tend to favour old manual lenses for this with aperture ring or do you use modern lenses and blue tack to set aperture?
