edward Posted November 19, 2006 Share Posted November 19, 2006 There used to be a nice picture here on the online help but it now seems to be missing: hdox://houdini/content/commands/guide/exp_matchcam.html Regardless, the equations on there should help.

Netvudu Posted November 19, 2006 Author Share Posted November 19, 2006 thanks for the aid edward...This equations can be helpful indeed...but the problem is for that example it uses the default 41.4214 as aperture x value...why?. I mean, I can get all the others value from Lw, but not the aperture because there Quote Link to comment Share on other sites More sharing options...
edward Posted November 19, 2006 Share Posted November 19, 2006 but the problem is for that example it uses the default 41.4214 as aperture x value...why? It doesn't matter what the value is. What matters is that it's in sync with the other camera values so that the relationships hold. I'm guessing that the 41.5214 is taken from some real world camera of some sort.

edward Posted April 11, 2008 Share Posted April 11, 2008 I think it's aspect ratio Quote Link to comment Share on other sites More sharing options...
