Is 4K a game changer?

The former is much higher due to Nyquist’s oversampling recommendation.

Although it is variable due to film stock, exposure, camera movement, prime (or not) lensing, testing has shown, generally, that the effective (true) resolution of Super 35 film to be in the range of the low 3-ish K’s -

In the above post, I notice that hyperlink to the respective thread on Roger Deakins’s forum has since expired or been deleted since I referenced it back in Jan. of 2012, so here is essentially the same assessment from David M. regarding the resolution topic as posted on the RED forum -

All I would add to last paragraph of David’s post ^, since he is a cinematographer rather than a post production specialist, is that if one desires to harvest all the detail off Kodak Vision 3 35mm frames, the typically used 10bit dpx may not be adequate.

For those not following, the Northlight outputs 10-bit or 16-bit log DPX/Cineon files (see page 2, upper right - http://www.filmlight.ltd.uk/pdf/data...Northlight.pdf
). Selecting 16-bit log DPX output may be necessary for optimal scanning (archival quality) of Vision 3 35mm film but, that increases the cost of the project substantially. Luckily, Vision 3 stocks weren’t introduced until 2007 and later.
