A yellow filter has always been the “classic” first choice filter for black & white film photographers. It gives an excellent balance between photographic effect and ease of use making it a useful and versatile accessory.
 
Many photographers use a yellow filter to “bring out the clouds”. This works by darkening the blue sky, giving a greater visual separation between the darkened sky and the white clouds on the final print. A yellow filter will also give improved penetration of haze and fog.
 
Although a yellow filter darkens blues, it reproduces green, yellow, orange and red in lighter shades. This gives more differentiation between the different colours of foliage while flesh tones have a more natural look.
 
Always factor in. 2/3 stop adjustment to your metering when using this filter.
