View Full Version : film back

Here is a quick tip for everyone. Mabye is more of a reminder to everyone. Don't forget about your film back. Before you do a single thing when matching to any plate, is change that filmback. Just had 6 artists have to re-do a bunch of work for such an easy tweak. Then check the horizontal and vertical to make sure they are the same against a chart. JUst did a 10mm shot, that was incorrect in LIghtwave, was actually 8mm in Lightwave with a Super 35mm filmback. Thought it looked wrong, good thing I checked.

I am making some cgi shots for a shortfilm, but I believe it is being taped on DV or DVCAM... what type of specs should I question photography people, just to be on the safe side? :D

CCD size, check the cameramanual

walfridson's right. There is a CCD option in the film back settings from lightwave. Just scroll through the pulldown menu. Note though, that it's pretty hard to figure out the zoom on those things. So it's always best to keep the CG shots at either no zoom, or full zoom. Otherwise it might look a bit hokey. Another problem is that zoom camera's tend to have quite a bit of barrel distortion. It best to meter them for barrel distortion on a checkerboard. Then use worley's lens plugin to correct for it. Don't let whom ever is operating to use auto focus, switch to manual for a bit more controll for yourself. With that in mind actually you'll need the t-stop base for correct depth of field. Good luck.

Also something that most of us forget is there are even different 35mm movie camera back sizes too:

Maybe this Field of View calculator (http://www.dudak.baka.com/fovcalc.html) might help too :)
