Hello Michael
Any number of factors can result in poor results from colour negative film...
Without closer enquiry, your method of exposure - "light meter/adjust shutter speed/adjust aperature/shoot" - is correct. Modern cameras using modern film emulsions get it right most of the time, too
In my experience, fault is often with the lab - especially the "High Street" mini lab variety,
Experimenting with film to improve results can be costly, but here's a few things to try:
* Select a well exposed film strip and have several different labs produce prints. Compare their results; you might be amazed
* Try rating your film at differing ISO settings. To make this meaningful, keep careful notes and shoot a number of scenes, exposing 3 frames at each one. Expose all 3 frames identically - but alter the ISO setting of each. If using 400 ISO film, I'd suggest the following: (i) 400 (ii) 320 (iii) 200. Process the film normally, refer to your notes and carefully check results
* Repeat the process with a variety of films. One is spoilt for choice
Have fun
