Hi Moose,
thank you for your elaborate answer!
Indeed I should havbe been more precise, and perhaps I should try some
more own research before posing such a type of question. In the case I
descibed I used Ilford XP, I did not use the DX setting but eventually
changed the ISO setting for the indoor and outdoor pics between 200 and
800. I had done that before with an XA with decent results. With the
OM40 case, I have to admit that I mostly used program mode. I cannot
recall if I tried AE. I think I should go back and use some slide film
to get clearer answers....
Thanks !
Rainer
