Can't say I miss the place Tom but good memories of some lovely colour on the way to and from work...captured just as I remebered it. Good compositionand good colour.
I would say it is possible to correct the buildings but my skills in ps are very limited..I would suggest some critique from people's method's would help....Cassiecat does lots of vertical / horizontals in her building images. I had a go at the Select all / Edit / Transform / Distortion
advice that Platchet gave me the other day..it was better but still not correct.
Like yourself I am a fairly new owner of the 5D2 and this weekend I have had my 1st real chance to do some landscapes with it...and was disappointed at my results. I was not aware there are banding issues with the camera not having seen any before but in this image I think I see some of the issues I have had myself...particularly in the reeds and the building - when viewed large I believe there are some banding lines?. Interested to know if you have noticed any of this?
