Here is something to do over the weekend and the best thing about this is free. We found a site which gives you printable lens hoods which can save you come money. So all you have to do is jhead over to lenshoods.co.uk (full frame sensors) or lenshoods.net (1.5x and 1.6x crop digital sensors), all you have to do is find your lens and download the PDF and print it. Dont forget to print it on to heavy paper or cardboard, something that will not let light through.
