Devin Johnston Posted November 7, 2006 Share Posted November 7, 2006 Most of the time 50 DPI is the highest rez I'd use for a billboard image, it would be even lower if the sign was extremely large. The thing about large signs is people won't be viewing them up close so you can get away with a lower resolution. Link to comment Share on other sites More sharing options...

Brian Cassil Posted November 7, 2006 Share Posted November 7, 2006 IMHO there is never a reason to render something larger than 5000 pixels wide. Even if that means the printed image would only be 30 dpi or so. Here's a case in point. An IMAX screen is larger than any bilboard would be and the resolution on that is only 4000 wide. I doubt anyone would ever say the image on the IMAX screen is to pixely. Link to comment Share on other sites More sharing options...

kippu Posted November 11, 2006 Share Posted November 11, 2006 how much did you render at blade? Link to comment Share on other sites More sharing options...
STRAT Posted November 11, 2006 Share Posted November 11, 2006 yup, 5000 pixels should be ample. i've just been asked to render for billboards, but they havent told me the billboard size yet, so i'm rendering as we speak at 6000 pixels. Link to comment Share on other sites More sharing options...
blade911 Posted November 11, 2006 Author Share Posted November 11, 2006 @ 4500 pixels. luks decent from a distance! neway i had this doubt. how do we relate pixels to dpi? Link to comment Share on other sites More sharing options...
STRAT Posted November 11, 2006 Share Posted November 11, 2006 pixels are dpi. you only need worry about dpi and pixel size when you have a specific size to print/render to. ie, a 2000 pixel image is exactly the same size in pixels whether it be at 100, 200 or 300 dpi. but a 20 inch picture will vary in pixel size at different dpi's, even though it's physical dimensions stay the same.

Ernest Burden III Posted November 11, 2006 Share Posted November 11, 2006 An IMAX screen is larger than any bilboard would be and the resolution on that is only 4000 wide. Where did you get that? For the most part, IMAX is a film projector, not digital (though I'm sure that's coming). A piece of 35mm film has an effective resolution of about 5000 to 6500 pixels depending on grain. IMAX uses 70mm film, which would be 4x as resolute as 35mm, but it runs through the projector sideways, thus delivering many times more surface area. So work shot directly on IMAX film would have an effective pixel size WAY beyond 4000. Perhaps our good friend Chris Nichols would verify or adjust my figures, he works with this stuff daily. If I'm off I would like to know it. Link to comment Share on other sites More sharing options...
