Give your photos a softer more vintage filmic look right in camera with a black diffusion filter

Digital cameras have a distinct look about the images they create. There are a few characteristics which define them. Generally, they are sharp, with a broad range of coverage of the light values from bright to dark. These factors make for great snapshots. Digital cameras are designed to photocopy what is in front of them, but their automatic modes have no ability to reproduce mood and atmosphere. You can greatly enhance these characteristics within your images by dialling in settings manually and shooting through a filter like this.

REMOVE HARSHNESS
If you are looking to give your images a unique look and style, a black diffusion filter may be a great option for you. It changes some of the key characteristics of a modern digital camera image. Firstly, it diffuses the image. The coatings on the filter slightly softens the image. A soft image is not the same as an out of focus image. Softening filters have been used in cinema for decades. This removes some of the harshness of a modern camera. It preserves the sharp focus but reduces some fine details. This is particularly good for capturing skin in a more forgiving way and make objects appear more glamorous as imperfections are blended and minimised. This can make it great for fashion and beauty applications.

BLOOM HIGHLIGHTS
The second effect the filter has is to bloom light sources. An additional effect of the filter's diffusion is to create a glow around light sources. If a light or neon tube is in the shot it gets a dreamy glow effect or "bloom". This is very impactful in street photography at night (think Blade Runner). The combination of these two characteristics are images which appear lower in overall contrast. You can underexpose shots for richer blacks which helps to create mystery, while the bloomed highlights have such smooth graduation in tone that the resultant contrast is more like a vintage filmic look.

USES
The effects of this filter are well suited to stylised product photography, portraits, landscapes, narrative story telling work and urban street photography. As it impacts the look of light sources so strongly it is most effective in night shots, its characteristics can be more subdued in daylight shooting. Because of its stylised look it is less suited to news, documentary or reviews.

YEARS OF POPULARITY
The effect created by a black diffusion filter has been so popular that digital editing has tried recreating it in various forms. A popular image editing technique called the Orton Effect works to emulate the look created by a Black Pro Mist or this black diffusion filter. You will always get a better effect in camera than doing it after the fact in post processing.

UNDERSTANDING FILTER STRENGTHS 1/8 vs 1/4 vs 1/2 vs 1
These filters come in a variety of strengths. These are 1/8, 1/4, 1/2 and 1. The filter with the least intense or pronounced effect is the 1/8 version. Each progressive density provides more contrast and highlight reduction, allowing for a progressively soft, pastel-like quality of light.
This is a popular choice as the effect is subtle and not overwhelming. The other 1/4 is also very commonly used as it has a more obvious effect without being overwhelming or distracting. The 1/2 option is a strong effect and is obvious. For this reason the 1/2 and 1 strengths are used more sparingly as they create a very stylised look. It is a great and a dramatic effect, however it may not be suited to every situation unless adream like quality is desired.

FEATURES
The K&F Concept 1/4 Black Diffusion Filter has a smart ultra slim frame design machined from high quality aircraft aluminium. Made from aluminium, the frame is strong and durable to stand up to continuous use, day in and day out. The frame is also very lightweight, which means comfortable all-day use. At only 3.3 mm once attached, the filter frame is ultra-thin, avoiding vignetting and dark corners by casting shade or being visible to the lens in the corners of your frame. This ensures a filter effect which is consistent over the entire frame. The frame is double threaded to attach and combine with another filter. This allows extra versatility by combining the effects of more than one filter type, allowing you to adapt the mood and atmosphere to fit any occasion or condition without the need to add those elements through editing.

BUILD
The filter lens is crafted from high precision Japanese optical glass. The lens is treated with a double-sided polishing process which ensures high-definition image quality at up to 8k. The filter also undergoes a double-sided multilayer coating process where 28 layers are applied to the lens. The most prominent of these coatings, is the anti-reflection coating, which effectively reduces reflection internal reflection problems. The other benefit of these coatings is that they increase the effective light transmittance through the filter. The multi-layer coatings are waterproof, scratch resistant which protects the lens from a slip of the hand or unforgiving elements. A carrying case is included so you can carry your filter with you to wherever your photography takes - scratch free.

WHAT SIZE DO I NEED?
This black diffusion filter is compatible with all 67mm lenses. Please verify your camera's lens thread size before ordering. Your camera's lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by the symbol for diameter.

So, if you are trying to create a different look to your work. If you are aiming to create something more filmic, narrative or stylised in order to stand apart, try the K&F Concept Black Diffusion Filter.
