Hi Frank, The 2:3 aspect ratio alone is not sufficient. When I used the default settings for filmsize (0,03x0,022) the aspect ratio (3:4) was correct. This was based upon the size in pixels of the picture (2560 x 1920). With the default settings I mean the settings Realsoft suggests. Nevertheless I had to set the Focal length to 160 mm instead of 191mm or 48,25 as mentioned in the exif data. Thank's to Cris, was it Cris?, I only saw initials cm ;), I had a look on the internet and found the following page: http://www.dpreview.com/news/0210/02100402sensorsizes.asp
My camera is mentioned in the table (minolta dimage7). This camera has a 2/3" CCD. According to this table the sensor size is 8.8x6.6 mm. This also has the 4:3 aspect ratio. When I put these sensor sizes in the width and height fields in RS I can fill out the 48.25 mm focal length to get a correct match. I tested another viewpoint and found the same correct match. When you use the correct aspect ratio but have the wrong filmsizes the object in the 3D scene will be too big or too small. Quite an interesting day ;) Arjo. > > After I read Cris's mail on the subject I looked up the aspect > ratio for the > ccd in my camera. Guess what, 2:3!! > > Frank Bueters > >
