Dear all, I am struggling on which colour filter to be used in daytime without sun shine and cloud to produce a good contrast and detail architectural B&W film photo ...... Any suggestion..?
Under overcast it's tough due to whiter light so most filters have a more linear response. That said, try a deep yellow (minus blue) to deepen shadows as much as possible. A push will increase contrast a little, but also add grain.

I don't think a red will help with overcast skies - this filter is best used when you have clear blue alpine skies, and wish to separate the sky form the white mountains.
A good example is Ansel Adams Monolith, the face of Half Dome:

I would go with Jack's suggestion.
In general if you are using B&W film, it pays to have a spectrum of filters: Y,O,R,G.

As an aside since Swiss brought it up, if you're going to shoot panchromatic B&W films, you will want a selection of colored filters -- in addition to lightening up their own color and darkening their opposite:
Yellow -- renders most panchromatic films in a natural relative contrast under normal light;
Deep Yellow (minus Blue) -- darkens blue skies appreciably and increases contrast under normal lighting;
Orange -- lightens human skin and fall foliage -- ironically does not appreciably darken blue sky, but will render it similarly to normal Y;
Red -- darkens blue sky dramatically while leaving white clouds white for dramatic contrast, lightens human skin but often to the point of greatly accentuating flaws or veins, so not usually a good choice for people;
Green -- often the best choice for smoothing human skin tones, lightens green foliage;
Yellow-Green -- older choice for smoother, but realistic skin tonality;
Blue -- they're out there, but in all honesty I never saw a reason for them except for product imaging where you were trying to hide or accentuate a particular hue of blue.

Most times I love a green-yellow filter. Sometimes with the b&w-style "Panchromatic" (C1).
P.S.: If your wife knows everything... it's mostly not good for your gear.1 Member(s) liked this post
