@goanna Very helpful - thanks.
As usual, the DOF calculator site can be useful for lens choice as well as positioning of talent and furniture in such a small space.
@goanna I think we'll end up shooting late September. So may be a bit hot here on east coast of US. Hot is good though as sweating during this scene is perfect!
Or click on https://www.youtube.com/watch?feature=player_detailpage&v=Ksn_s-Aa_pQ#t=44 to start the video at second in-room scene at 0:44.
@matt_gh2 Good luck with the Northern Hemisphere autumn temperatures. Films like Citizen Kane appear dark, but the sets were so brightly lit and hot the actors were apparently getting suntans and sweating!
@goanna That's exactly what I was thinking. I've had good luck with those cheap $30 LED 160 lights, so why not get a bunch of them. (That's a cool Orson Welles story.) I think I'll be okay at f8 or f11, but I'll test all f stops ahead of time. Thanks.
Lots of light will let you stop down as far as you need (f/22 or so) Luckily, LED lights are cheap, low-wattage and cool to work with.
BTW, even as a novice filmmaker, Orson Welles so insisted on full DOF that he once refused to accept his DOP's insistence that they had to resort to opening up the aperture on a particular shoot: he asked the DOP what frame rate they were shooting at: the reply was 24 fps.Welles then suggested they shoot at 12fps, therefore letting twice as much light enter each frame, allowing them to tighten up the aperture another stop or so and finally allow the everything-in-focus look he insisted upon. This they did, successfully, with Welles, as actor walking and performing all his movements slowly so as to appear normal upon 24fps projection.
@CRFilms Tested an 18ft x18ft room using 28mm lens on GH2 and it was enough in terms of field of view for what we're doing. So I'm not too concerned about wide angle lenses, but I'm curious to know what people do to get the whole frame in focus from front to back, in terms of which f-stops to use, if some lenses are better than others, or even if some settings/patches are better for this. Thanks.
@matt_gh2 what cam will you use? Gh1/2/3/4 etc...? Even a stock 14mm with the cam mounted flush on the wall or on the floor will show a lot. If that's not enough the 14mm with wide angle adapter will turn it into 11mm for another $100 or so. Worse case, get the 7.5mm and defish in post. Problem is, once you go past F5.6, you need to add LOTS of light.
Also, what about renting or buying a GoPro 3+ Black? Deep DOF and with 2.7k to make defish easier or keep the fisheye as an artistic choice. Or get an external recorder for 1080p 4:2:2, though not 100% if it outputs uncompressed.
@goanna Lol - yeah - shooting a scene in a jail, and don't yet know if it's an actual small jail cell or larger holding room. Will know once we do location scout. Hoping to get most of the room in focus, so looking for tips on deep DOF, in terms of lens choice and use, as well as best patch/settings to use.
@matt_gh2 12-foot room? Yikes! You might have to use a 12mm lens at f/22 and do as Orson Welles did - either cut a hole in a wall or a hole in the floor:
Any recommendations on which lenses and f-stops combined with which settings/patches would yield the best deep DOF? I'm shooting a scene in a room that may be anywhere from 12 ft x 12 ft to 20 ft x 20 ft, and wanted the whole room to be in focus.
