Topics I've Started

Do larger formats create a unique optical perspective?

05 March 2018 - 03:35 PM

This debate has been raging now for several months, picking up steam again with the announcement of the Alexa LF.

 

I've tended to fall into agreement with Steve Yedlin, that you can match the "perspective", the field of view and depth of field, between formats of different sizes if you adjust the focal length and f-stop.  But some people's tests have shown a shift in optical perspective (compression/expansion) once you switch to the correct focal length that in theory compensates for the difference in format size.

 

To my eyes, that difference seems to be more due to differences in lens designs plus some adjustment not being made for where the optical center of the lens is, the nodal point, etc.

 

I tried to reduce the variables here by shooting this quick test on the same camera with the same zoom lens, once framing for the whole sensor (APS-C in this case) and then zooming out by 2X and framing for a sensor area that would be half the size -- so roughly shooting at 50mm and then at 25mm, and shooting the 25mm version with the f-stop opened up by 2-stops to match depth of field more closely. 

 

I cropped the 25mm version by eye so there is some minor image shift, and I think zooming from 50mm to 25mm does change the "shape" of the lens distortions so there is some shifting of elements in the frame, but my general impression is that the 50mm and the 25mm version (on a format that would be half the size) match.

When I've tried this test before by switching from a 50mm on a FF35 camera to a 35mm on an APS-C camera, there was some perspective shift as if I would need to move the camera an inch or two forward or back to correct (and zoom in or out a little). Plus I was physically switching from one camera body to another so wasn't in exactly the same place when the two images were shot.


Young Mr. Lincoln (1939)

11 February 2018 - 12:43 AM

I just watched the new Criterion blu-ray.  A wonderful movie by John Ford, sort of a simple drama with a lot of interior dialogue scenes, not an exterior western, with a great performance by Henry Fonda. Shot by Bert Glennon (I worked for a month with Jim Glennon, his son, on "Big Love" just before he passed away) with an early exterior scene shot on the Sacramento River by Arthur Miller.

 

The wide shots by the river are beautifully framed, reminding me of Miller's work on "How Green Was My Valley":

The first time you meet Lincoln in the movie is shot under a high noon hard sunlight, and throughout the film, Fonda is ofter lit with a high top light.  I think this was done for a couple of reasons -- one, it brings out Fonda's cheekbones, making them more like Lincoln's, second, it gives Fonda a sculptural quality reminiscent of the statue in the Lincoln Memorial, and third, at times the shadow under his cheeks and chin give the impression of a beard:

This shot near the end was done on the backlot of 20th Century Fox in the area where Century City now sits:

I worked four months on this doing additional photography plus one whole episode, there are about three shots of mine here you can see if you dont blink.

Four months of shooting 35mm film!
