Sen­sor Size

3D World - - TUTORIALS -

When smart­phone mak­ers men­tion the specs of their lens, they usu­ally equate it to a 35mm equiv­a­lent. This means they are com­par­ing it to a full-frame cam­era sen­sor that is 35mm across. As most phone sen­sors are around 4 or 5mm across, this is a big dif­fer­ence. Make sure when match­ing footage for VFX to get all the cam­era data you can, as most 3D ap­pli­ca­tions can ac­count for sen­sor size in the cam­era ob­ject. Lens type, fo­cal length, f-stop and cam­era model per shot are the key in­gre­di­ents from which a cam­era solve can be de­rived.
