hi simon, thank you so much for your very useful comments. it has really helped me to understand about filters. i have been looking at your landscape photo,s. they are magnificent. can you tell me what lenses you used to take them. also would canon extenders work ok with my lens. and are they worth the money. and do extension tubes work ok. kind regards gboy. (geoff) take care.
hi simon, thank you so much for all your help. very kind of you to spare your time. kindest regards. geoff. take care.

No problem Geoff..to be honest I'd much rather be out taking photos but the weather here in North Wales isn't great at the moment, talking about photography is the next best thing - that probably sounds a little sad
