Hi, I am one of your new listeners all the way from Kuala Lumpur, Malaysia, and I have a question about ISO "Film Speed" setting on my dSLR. I am a hobbyist photographer and I think I understand how the "film speed" of the traditional negative films work: more sensitive film, less light needed, more grain, etc. But how does this carry over to a digital camera? Does the sensor not have it's own native "speed"? or does changing this actually changes the way the sensor pick up light? BTW, I have a second hand NIkon D50, so no problems with buying second hand... OK, granted I work with the ex-owner of the camera so he better have not sold me a lemon :) Love the show! Yours Truly, Joe Lim
