In the first one, it looks like the Graphic camera might have a teeny-tiny bit of tilt with the bottom of the front standard pushed out. But it also looks like he's actually taking the photo with a DSLR he's got perched on top of the Graphic, and that DSLR has a Lensbaby mounted. On 10/19/2015

Depends on the focal length of the lens and aperture and film format. But yes even with relatively slow lenses you can have very shallow DOF even on large format. A not uncommon lens for portraits with medium format would be something like 210mm with a maximum aperture of f6.7. At a

Larger formats bring other things to the table beyond resolution. You'll never get the imaging characteristics of a banquet camera by stuffing more bazillion pixels into a 35mm format sensor. Godfrey > On Oct 18, 2015, at 5:18 AM, Collin Brendemuehl > wrote: > >

That "3 layers composition" thing bothered me too. The image is too small to read the fine print. I recognized the image was a Foveon. Wondered if it was saying the "super resolution created by SR" created a virtual Foveon sensor? Guess not. On 10/17/2015 7:26 PM, Mark Roberts wrote:
