Hi Paul, Sorry I know you sent this a while ago but I've just got around to catching up! Had a quick scan of the ensuing thread but, as far as I could see, nobody mentioned signal:noise ratio in relation to pixel size. In a nutshell, the larger the pixel, the better the image quality as a greater signal can pass through it (within reason I suppose!). The smaller the pixels within a given chip, theoretically the quality deteriorates as the noise:signal ratio is higher. Take a look at this link posted a while ago (thanks Ian...): http://www.wyofoto.com/Digital_Image_Quality/Image_Quality.htm Best wishes, JL -- :: JACK LOWE PHOTOGRAPHY :: +44 (0)191 224 5150 :: http://www.jacklowe.com :: DIGITAL SERVICES http://www.jacklowe.com/digital =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
