red dwalf Posted February 23, 2015 Share Posted February 23, 2015 (edited) nice effort Andy. those lovely big chips on those canon cameras give a great field of view. was that cropped a little from the original if you are using a camera lens ?

andyboy1970 Posted February 23, 2015 Author Share Posted February 23, 2015 Cheers Rob. Its very slightly cropped at the edges, the Raw from my camera is in the region of 5100x3300 pixels (18Mp). I resized it in PS because the original is 82Mb! so it is slightly compressed but still a PNG file. The lens I have (Xmas pressie) is a Professional Canon lens (15 element Apo) and is designed for full size chip cameras as well. The sensor end of the lens is about 40mm in diameter.
