Can a white stability filter be made higher? The workforce behind the unique ExpoDisc believes so, and the brand new ExpoDisc v3 is the newest effort at making the quickest, most correct white stability device.
Do you continue to want to make use of a white stability filter to maintain your colours in the proper place, when taking pictures, in a time when AI is in all places and, apparently, digital and “repair it in publish” rule? ExpoImaging believes so, and that explains why the corporate is popping out with a brand new model of its in style ExpoDisc. First launched virtually 20 years in the past, in 2004, the primary ExpoDisc was a magic piece of kit. As photographers explored digital, it turned clear that even with sensors as a substitute of movie, having the means to maintain your whites white and all the opposite colours the place they need to be, was an asset that photographers who wished to have most management shouldn’t be with out.
I’ve the 2 earlier variations of the ExpoDisc, which I used intensively in my very own work and for workshops, the place I’d present folks how the filter helped to get consistency when photographing. ExpoDisc 2.0 is now discontinued, as ExpoImaging introduces the ExpoDisc v3, which is, the corporate says, “our newest effort at making the quickest, most correct white stability device we will.”
The ExpoDisc 2.0 was nonetheless one of the best available in the market, even so, the workforce at ExpoImaging are all the time on the lookout for methods to make it higher, and that’s how ExpoDisc v3 was born. Why? you could ask. Nicely, as a result of as expertise evolves, so do supplies, and the brand new diffusion supplies integrated into ExpoDisc v3 carry out higher throughout the seen spectrum (380-700nm), offering higher white stability outcomes when taking pictures in cool open shade or very heat mild.
Thinner, with a brand new bayonet mount
ExpoImaging says that “the improved efficiency of the brand new supplies extends past the seen spectrum from 700-2200nm (close to infrared), and allows use of the ExpoDisc v3 to set white stability when photographing with an IR-sensitive digicam.” So, photographers (and anybody needing a device to examine white stability) get a brand new filter, with improved extensive spectrum white stability for a similar value – $ 49.95 USD – because the earlier model. However there may be extra, because the latest model introduces a brand new skinny design with bayonet mount step ring.
In reality, the brand new ExpoDisc v3 design is thinner than the ExpoDisc 2.0. The ExpoDisc v3 could be comfortably held over lenses 82mm or smaller, and it additionally incorporates a brand new bayonet mount permitting it to be rapidly connected and eliminated out of your lens utilizing the included ExpoDisc v3 bayonet mount step ring. A single bayonet mount step ring dimension is included with every ExpoDisc, and extra step rings could be bought for different lens sizes.
The ExpoDisc can be utilized to set an in-camera white stability utilizing your digicam’s customized white stability process. This tradition white stability will probably be integrated into your photos if taking pictures JPEG, or will probably be added to your RAW photos because the ‘as-shot’ white stability. ExpoImaging claims that “this protects an incredible period of time enhancing photographs later as each picture could have a impartial, measured white stability with out having to regulate sliders. Cease fixing your coloration later with software program.”
Though you could suppose that this can be a device for photographers, the ExpoDisc v3, as earlier variations, works for each nonetheless pictures and for video. Use your digicam’s video white stability process to use a customized white stability to your video. This can be a big time financial savings since correcting coloration in video is much more time consuming than for nonetheless photos.
Additionally used for incident publicity metering
ExpoDisc v3 will also be used for incident publicity metering. ExpoDisc v3’s mild transmission profile has been adjusted to 14.5% which is according to most digital mild meters and can present a more-centered histogram on fashionable digital cameras.
The ExpoDisc v3 is, like earlier variations, calibrated and licensed within the USA. ExpoImaging notes that “we check and certify each ExpoDisc at our California facility to take care of strict high quality management requirements. The ExpoDisc is examined by hand on a transmission spectrophotometer to make sure its neutrality. This neutrality is necessary as a result of utilizing a non-neutral device for white stability can really add undesirable coloration casts to photographs. Each ExpoDisc v3 features a high quality management card to certify its neutrality.”

Penning this piece of stories in regards to the new ExpoDisc v3 made me suppose if a filter of this kind can be utilized with smartphones, to make it simpler to maintain the whites pure. Does it make sense? Is it even possible? A fast expertise with each a Samsung and Xiaomi smartphones means that the filter – I used model 2.0 – works with the smartphone to get the white stability proper, and a reference picture could be captured, and possibly used, when in publish, to seek out the right white stability, for topics photographed beneath the identical mild.
Whereas this wants some extra testing, and it´s basically simply an educational expertise that might not be adopted in actual life utilization – and even make sense for many smartphone customers, it’s attention-grabbing to have the ability to strive working with mild in such a means. It gave me a cause to select my ExpoDisc filter from the shelf behind me and be amazed on the magic methods we will use to regulate mild in pictures. Even with a smartphone!
