Hello all:

 

I am interested in determining 'best resolution' using the Red Epic Camera in 5K with a sharp lens.

 

My method is as follows:

 

Red Epic at 5K with 3:1 compression ei 800 and an Arri Master Macro 100mm with a T5.6 pointed at a Century test chart at 51 X focal lengths as described in the instructions.  I very carefully checked the flange depth on the camera.  Very carefully checked focus.

 

I shot a clip at 24fps and then debayered using Red Cine X software and taking a full resolution still as a 16bit Tif. and exporting the still.  I then examined the still using Photoshop and enlarging (pixel peeping) the image.

 

My results are:  56 lines/mm

 

Any thoughts?  I looked for help on the Red User Board but have not gotten any feedback there as of yet. 

 

Thank you,

 

Neal Norton

Director of Photography
