Rasmus Eriksson Posted October 28, 2020 Share Posted October 28, 2020 As the title says, dose Celluloid film have problems with Moiré Patterns? Lets say super 16mm shooting a led wall? Link to comment Share on other sites More sharing options...
M Joel W Posted October 28, 2020 Share Posted October 28, 2020 No. The film grain pattern is too random. You won't have issues with moire as you might with a digital camera where it's a grid shooting a grid. However, if you are shooting mosquito nets or something where there is moire visible to the eye, it will appear on film, too, of course. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted October 28, 2020 Premium Member Share Posted October 28, 2020 No -- but once you transfer that film image to digital and show it digitally, there is the chance of moire appearing at some stage. Since most people who shoot film rarely only show it on film, it is still something to deal with. Link to comment Share on other sites More sharing options...
Giray Izcan Posted October 28, 2020 Share Posted October 28, 2020 I haven't really detected any moire issues myself. I get lowcon prints scanned however so I don't know if moire is more of an issue with DI workflow as opposed to film prints. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted October 28, 2020 Premium Member Share Posted October 28, 2020 Moire is just the interaction of fine lines in the image with the grid pattern of various stages in digital distribution -- and those patterns (scanner, monitors, etc.) vary a lot in terms of resolution. It's very hit or miss and often when you do see the moire, it is happening for that particular monitor resolution, it's not in the digital master. At the scanning / telecine stage, there are anti-aliasing filters that can reduce the chance of the image itself creating moire patterns on the scanner but as we tend to work at higher resolutions these days, there is less chance of moire appearing from a film scan. In general, it's not something to worry about when shooting film unless you've got some thin venetian blinds in focus right behind an actor.

Giray Izcan Posted October 29, 2020 Share Posted October 29, 2020 It makes sense. Thank you David. Link to comment Share on other sites More sharing options...
Robert Hart Posted December 6, 2020 Share Posted December 6, 2020 Slightly offtopic but related. Due to mishap, some archived early generation videotape British TV shows in colour were lost. Some time back, old B/W filmed distribution copies were discovered in an African TV broadcast station, in Nigeria I think. In playing them via modern telecine, it was discovered that traces of colour were appearing. Apparently the resolution of the film was just sufficient to have also captured the unique moire pattern of a PAL colour TV image which carries the colour information. With some R and D effort and the power of modern digital technology, it was apparently possible to recover in colour, the original coloured versions of the shows.
