I'm loving the pictures Peatmoss!
So I went out and bought a polarizing filter for my macro lens, apparently it will reduce unwanted reflections and make my pics look a bit more "contrasty" or whatever. I like it so far, makes the pics look better if I have it on the right setting.
I take my "macro" pictures with a regular 18-55 lens on my Canon EOS 550D with all '+1', '+2', '+4', '+10' macro filters and a 'UV' filter combined and screwed onto the lens. Compared to an actual macro lens, the picture quality is not that great but I'm going to have to endure with it until I can save up for one!
The kit came with '+1', '+2', '+4', '+10' macro filters and 'UV', 'CPL' (polarising) and 'FLD' filters for only £12! Great offer for people on a low budget and can't afford proper macro lenses! (like me... I'm still 13)
TBH, I haven't used the CPL or FLD filters yet!
They're still in the case they came in! XD I think I'm going to try out the CPL attached to the combination after looking at your pictures, I hope it 'constrasts' the colours in the image as you said!
