The only thing I would say is that your TV system is PAL, which is 25 fps. You can do the maths and work out what fps or indeed fp/hour you need to shoot to show a speeded-up scene. EG shoot at 1 frame per second and you will have a collection of stills that make up a movie (when run continuously) of 25 seconds of real time squished into 1 second of viewing time. Personally I work backwards. First I want to know what the subject is, say a garden scene, over the course of one dawn-to-dusk' day. Then I think about what a comfortable viewing time would be for such a scene - obviously if there's a lot of activity in the garden (sunbathers coming and going) then the 'faster' the sequence, the less you will see of them unless they are there for hours. Say a good length here would be a 2 minutes screen time. Dawn to dusk would be (say) 10 hours (to make my maths easier :) 2 mins screen time X 25fps = 3000 frames 10 hour shoot = 36000 seconds 36000 divided by 3000 frames = 12 so 1 frame every 12 seconds gives you 5 frames a minute, 300 an hour, 3000 over ten hours Try a test - it's too fast for sunbathers, slow it down, go for a frame every 30 seconds Other subjects with little movement (cityscape?) might be too slow, so try a frame every 5 secs etc. Experiment :) And publish!! Youtube is your friend :) This might give you some ideas - absolutely breath-taking: <http://www.youtube.com/watch?v=_xMz2SnSWS4> Note tracking and panning shots! -- Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ---------- http://www.cottysnaps.com _____________________________ -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
