Hi again and thanks indeed for all your kind replies...
I have been away for a few days and was shocked when I saw the amount of posts!!!
After reading some of your answers and opinions I was anxious to try a few things
so off I went to the same place (to keep things familiar..)same camera and same film. Leica M7, summicron 35 ASPH, Kodak C-41 BW film and this time took my hand held meter...processed the film in the same lab to avoid any more variables.
Set my tripod and focus (pretty normal so far..).
Meter WITH HANDHELD METER (this time I mean it...

).Overcast day, late afternoon, sun in my back. Incident reading as the contrast in the image was not dramatic...
My Sekonic gives very accurate readings in thirds of stops, so I did 1 esposure rating the film at 400 ISO and then repeated the Photo adding 1/3 of a stop each time to rate it at 350,320 and 200 ISO. I finally added the meduim yellow filter and dialed a full stop compensation for a picture rated at 200 ISO with M/Y filter.
Scanning:
16 Bit Greyscale; sharpening: Low; Grain reduction: Low ; Dust removal : Low.
As suggested in some posts previously I did set the black and white point in the extremes of the histogram in the scanner´s software and that really helps to improve the image.
I attach the images in the exact same sequence just in case you may want to have a look.(ISO 400,350,320,200 and 200 with Y filter).
This is only one of the photos I did that afternoon but I dont see the point of bothering you with more boring images when this one pretty much tells the story..
I will be very interested in your comments but I believe it´s very obvious the negs. look better the more exposure they receive.Rating at 200 ISO gives a neg. which is much more contrasty and strong, though you might need to be a bit more carefull with strong highlights...
No further post-processing has been applied to the photos and I understand that the images could look better with some work, but this images far from being of any interest or artistic value

have just been shot to ilustrate this post..
Thanks again for all your kind/warm responses.
All the best, Erik.
