these are good and not as expensive as Lee. the early ones gave a slight blue cast which was very easy to get rid of not like Cokin which , if stacked, gave a horrible magenta that was a pain to remove. the later ones do not have this , i used a 10 stopper of theirs and that had no cast at all. i believe David Storm uses or used these and he seemed happy with them. here is a link to their site

taken with this lens

excellent shot, one i missed when i was doing Village Churches, Norman/Saxon ones so much more interesting than the Victorian ones. it is in Gloucestershire Vic, about 9-10 miles from Cirencester, 3 miles from Fairford.

thanks for the comments and the last one is my favourite, just playing around with the software. Viveza i had never used as i was not sure what it was for but found a tutorial on youtube by Mark Hilliard post processing his IR images and this is what he used. it works very well, when mastered, as he shows. it can work on normal images as well when colour needs some adjusting without resort to selections or layer masks just a simple control point and repeat as required

definitely well spotted and well shot, butterflies can be the most awkward of subjects at times, take off just as you are about to shoot. at least the ones down here do. well done David

you flew the Pentax flag well

citizens advice office will know how to contact them i imagine

how long ago did you buy it Louise? if it is out of guarantee then go direct to Johnsons to try and argue the known fault case or maybe before that you could talk to your local trading standards office for advice, they got my son a free repair with the advice they gave him on a car fault he had that the dealer wanted to charge £400 for . a second hand car at that which developed a known fault.
