I consider myself a pro-amateur photographer, some years ago
updated my equipment with and EOS A2E camera and  
EF 28-105mm f3.5-4.5 USM   and   EF 100-300f4.5-5.6 USM lenses.  
Also recently I bought a 550EX flash along with an extension chord.

I thought that this equipment will help me get some really creative 
pictures - but role after role of film comes back underexposed with
daylight and flash photography - any pictures that I take with self 
firing slave units (not wirelessly controlled by 550EX) to get an 
overexposed background - the subject comes out horribly underexposed 
and the background is not overexposed.  Mostly I use the P (Program mode) 
to override the exposure compensation.

Recently, I have started setting the ASA/DIN value of the film to 
1/4 of the value shown on film. (i.e. manually setting 200 film to 50).
This improved the results but I feel there is loss of contrast in some 
pictures.

All pictures at normal settings seem to underexpose by 1.5-2.0 F-stops.
Please suggest tests or remedies for the problem. Another friend of mine 
has the same problem using an EOS-Rebel body - is this problem on all
low end EOS products.

Also do you think the problem is related to developing pictures at a pharmacy
etc - that their printing machines try to correct every negative to 18% gray
to compensate for pictures taken with disposable cameras etc (in the process
darkening overexposed areas in creative pictures). If the printers at stores
do set to 18% gray do they analyze each negative or just the first print on the
film.
