Still a change more of our times! Saludos cordiales Luis -----Mensaje original----- De: lug-bounces+luisripoll=telefonica.net@leica-users.org [mailto:lug-bounces+luisripoll=telefonica.net@leica-users.org] En nombre de Don Dory Enviado el: mi?rcoles, 12 de septiembre de 2007 1:07 Para: Leica Users Group Asunto: Re: [Leica] Unsworth w33/now expos comp M8 Steve, I know this was directed at Tina, but I have had good luck underexposing two stops and bringing the image to what I think the values should be in Lightroom. Routinely, I underexpose 1/3 stop to keep from blowing the highlights. So, when shooting the M8, err on the side of underexposure; if the historgram starts at 125 and goes to the left you still can have an outstanding image.
