Photography Question

Perfect Prints but Underexposed Slides


 
 
I recently purchased a Canon EOS 30 and am very happy with the camera. I have run a number of Kodak rolls of print film (various speeds from 100 to 400 ASA) using the Canon and it has produced sensational results.

However … While putting through 3 rolls of Fuji Sensia slide film (various speeds from 100 to 400) most of the shots appear to be underexposed. This is extremely disappointing when I consider I needed these shots for an up and coming article.

Can anyone explain this phenomenon? Should I manually adjust the film setting for slide film to a lesser speed setting. Eg: using an ASA 400 … should I set the camera to 200 ASA to compensate?

See example images ... Example 1 has a very dark background. Example 2 had to be enhanced.

Most frustratingly…

  Print film has a much wider latitude (5-7 stops) than slide film (3 stops) so you must be more precise with exposures in slide film. With any film (and camera) its a good idea to run some tests to see what your actual ISO (aka exposure index) is for any given film. For example I know that when I shoot Velvia with my equipment I must rate it at ISO 32 not ISO 50. When I shoot with 160NC I rate it at ISO 125 (100 if using flash) not ISO 160. Using slide film will either drive you crazy or make you much better at exposure.

  Jeff,

Thanks greatly for confirming my suspicions. It will make my life just that little bit easier.
