I'm affraid it won't be long before I leave my treasured 4x5 at home on my trips to Yosemite. My digital has so much more resolution and sharpness that I don't see the need in lugging around 25-30 pounds of camera gear anymore.When I make 16x20's from my digital files there every bit as good if not better than my 4x5 negs.I'm going to Yosemite in May and will bring my 4x5 but I'm only bringing aroung 6-7 holders instead of my usual 12-15 holders.It's sad but it's the new reality.I'll miss composing the image on the ground glass and setting the fstop,shutter speed and I miss pressing the cable release.About the only thing I won't miss is people asking me "what kind of camera is that".I wonder if the digital age was around in the mid fifties would Ansel Adams had left his 8x10 at home?
