I recently saw some green-enhanced filters and yellow filters.

Anyone can share some real life experience of using this 2 filters? (yes, esp. you Ian :D )

Shadus, there's a whole series of green and yellow filters. Can you be more specific please.

Ok here you go, the rough guide to filters for B/W photography, this is not a full list, but these are the most commonly used filters.

Y2 (K2) - Wratten #8
A yellow filter, good for landscapes, general outdoor photography and sports. Blocks UV up to 485nm. Increases contrast between sky and clouds. Great as a general B/W filter and works very well with stone and brick etc in full sun. Also used with Ektachrome IR films. Filter factor 2.

Y3 - Wratten #12
An Orange filter, good for landscapes, architecture etc. Darkens sky and increases contrast significantly. Brightens Yellow tones. Blocks UV to 535nm. Also used with Ektachrome IR film. Filter factor 3.

Y0 - Wratten #16
A Yellow Orange filter. Great for Caucasian skin, and clears up skin tones wonderfully, especially freckles. Darkens up skies noticably in landscape shots and produces very good thunderstorm like clouds. Blocks UV to 545nm and can be used with Ektachrome IR film. Filter factor 2.5

R25 (R8) Wratten #25
A dark red filter. Great for landscapes, darkens Violet, Blue and greens. Produces stunning clouds and skies. Ideally suited for mountain and cloud photography. Lightens reds and oranges. Also used for Ektachrome IR film. Blocks UV to 600nm and has a filter factor of 6-8.

X0 (YG2,5) Wratten #550 (from memory)
Yellow-Green filter that's ideally suited for landscapes, creates greater distinctions between hues of green. Also excellent for outdoor portraiture with clean tinted skin tones and accentuated lips (Caucasian skin tones). Filter factor 2.5

X1 - Wratten #11
Green filter that's excellent for meadow and forest seperation in landscape photography. Also good for outdoor portraiture with soft lighting and backlight scenes. Filter factor 4. Can also be used to correct for tungsten light in B/W photography.

Hehe looks like I haven't been missed.

CK, when using colours with black and white film stock, the effect is not one of an increase or decrease in contrast generally, but by achieving the result by lightening the colours similar to the filter in the scene, and darkening contrasting colours. Green is sometimes used with portraits to enhance the film's response to the skin tones, and to set apart lips, etc. Red is often used to boost the contrast in the sky because it lets very little blue light through, hence "darkening" the blue parts of the sky while leaving the clouds light.

Ian, thanks for the informative B/W photography explanation :D

I'm unable to tell u wht filter it is as I didn't really take note of the filter name but I do know its not for B/W photography.

I remember tht they shop keeper told me to the effect that its a 'green-enhanced' filter. (Its in jap, so that's my closest translation). He say its good for taking greeneries. I'm pretty curious as I was taking some greeneries recently and it didn't turn out as nice as what I see on the net. So I'm just looking around at techniques, films, filters etc to achieve much more livelier greens :p

Perhaps I'm still naive in my photography skills. I'm just exploring :D

Thanks for the refresher. It has been like over ten years since I last touched B&W, coloured filters, etc. ;p

Ahh, Enhancing filters, Companies such as Tiffen and Singh Ray make these as does Hoya.

Singh Ray's enhancers are available to boost red, blue and green hues as well as a general all over accentuator for cold and warm hues. They aren't cheap at around $160-190 USD per filter.

Tiffen and Hoya's enhancing filters are cheaper and both enhance red, brown and orange tones, giving an increase in saturation and contrast.

The Tiffen and Hoya filters are made with didymium glass and are good for foliage, rocks and in some cases architectural work.
