## Description

Product Description               The ExpoDisc Portrait White Balance Filter is a calibrated, white-balancing filter with a warm-toned bias optimized for portraiture. The ExpoDisc Portrait White Balance filter is also effective for reducing the bluish cast on overcast days or at high noon; reducing the excess blue from flash and flash-fill; as well as warm high altitude shots. ExpoDisc is an easy to use custom white balance solution that eliminates the inconvenience and inconsistencies of other methods. It is a neutral diffusion filter that gathers ambient light from 180 degrees and passively transmits 18% of it through to your camera's light meter. The resulting "gray frame" accurately represents the average colorcast of the light in which the photograph is taken. ExpoDiscs do not screw in. They lack front threads and were designed to be pushed-on over the lens threads in order to facilitate a quick white balance.                  From the Manufacturer               ExpoDisc Professional Custom White Balance Filter The ExpoDisc easily mounts to your camera's lens by pressure mount or can be held over smaller lenses.

Image copyright David Guy Maynard. Why should I white balance with an ExpoDisc? Because it saves time. The ExpoDisc Professional White Balance Filter can be used to quickly set a custom white balance, virtually eliminating the need for RAW and JPEG color adjustments.  When used to set a custom white balance, the ExpoDisc consistently produces excellent color in natural, artificial, and studio lighting, and it even excels in difficult mixed lighting environments. What is the ExpoDisc Portrait Professional White Balance Filter? Designed specifically for portrait photographers, the ExpoDisc Portrait Filter enhances and accentuates healthy skin tones. Rather than producing an image file with neutral whites, the filter first neutralizes, then enhances the image with a subtle warming effect. The ExpoDisc Portrait Filter effectively adds pleasing red tones to the entire image, producing an image with subtle red highlights in the hair and skin.  Simply read and set white balance with the ExpoDisc Portrait Filter in place to consolidate several on location and post processing steps into one quick and easy custom white balance procedure. When used to set a custom white balance, the ExpoDisc Portrait Filter enables photographers to generate custom color at capture in a single, time saving step.

The ExpoDisc Portrait Filter is calibrated to add a slight amount of warming when compared to an ExpoDisc Neutral's white balance, for more pleasing skin tones. The set of images at right were taken using off-camera strobe light in a studio setting. The first image was taken using the camera's own Auto White Balance setting. The second image (middle) was taken using the ExpoDisc Neutral to white balance the camera. The third image (right) was taken using the ExpoDisc Portrait to white balance the camera. How does the ExpoDisc work? Your camera’s internal light meter measures the color temperature of light passing through the ExpoDisc to make an “in-camera” color adjustment. This color adjustment is applied to all subsequent images taken using the custom white balance applied from the selected light reading.  Or, if you prefer shooting in RAW and batch processing later, simply capture a reference image through the ExpoDisc to use later with your image processing software. How is the ExpoDisc different from other white balance tools? We individually adjust each ExpoDisc using multiple custom filters to correct for any variation in base materials. This precision ensures that your camera applies the correct color adjustments when setting a custom white balance.  Using an ExpoDisc is also easier than using unwieldy exposure targets and gray cards, awkward tools that often require an extra set of hands to hold and position properly. To use an ExpoDisc, simply attach it to the end of your lens before setting a custom white balance or metering for exposure. How are ExpoDiscs constructed? ExpoDiscs are made from multiple layers of custom formulated materials contained within a high grade anodized aluminum filter ring. We measure and calibrate each ExpoDisc at our California facility to exacting standards. The ExpoDisc's 18% light transmission is ideal for setting a custom white balance, as well as metering for incident exposures in ambient light. Will the ExpoDisc work with my camera? The ExpoDisc can be used with any digital camera with a custom white balance capability, including all digital SLRs and most point & shoot cameras. The ExpoDisc works with all major camera brands, including: Canon, Nikon, Sony, Pentax, Olympus, Samsung, Lumix, and Leica.  Auto White Balance (left), ExpoDisc Portrait (right). Images copyright Clay Blackmore. How do I use the ExpoDisc? Getting great color with the ExpoDisc is easy. To set a custom white balance with the ExpoDisc, simply place the disc in front of your lens and follow your camera’s custom white balance procedure to capture an incident light reading through it. For most cameras, this procedure takes about 15 seconds. That’s it. If you’re shooting JPEG you’re done. And if you’re shooting RAW, simply download your images as shot and save yourself valuable time correcting color. No special software, and no post processing required. Does the ExpoDisc work for video applications? Yes, the ExpoDisc can be used to quickly white balance any digital video camera with a custom white balance function. White balancing your video camera with an ExpoDisc will save valuable time in the editing room adjusting for color casts and inconsistent color. How does the ExpoDisc attach to my lens? The ExpoDisc was designed to make white balancing your camera easy. To help accomplish this, the ExpoDisc quickly attaches to the lens using an innovative friction mount design. When gently pushed into a threaded lens or filter, three small spring loaded ball bearings located around the filter ring slide over the lens threads to hold the filter in position until removed. Do I need to buy an ExpoDisc for all my lenses? No, if you have multiple lenses you can purchase an ExpoDisc to fit your largest lens. When using smaller lenses, simply hold your larger ExpoDisc flush over the end of the smaller lens. What ExpoDisc filter sizes are available?  ExpoDisc Professional Custom White Balance Filters are available in standard filter sizes, including 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, as well as 4x5.65 Video Format Filters.  Every ExpoDisc is individually hand calibrated, tested and certified in the U.S.A. Contents:ExpoDisc White Balance Filter - PortraitNylon Filter PouchYellow woven lanyardCertification CardQuickStart GuideWhat is a custom white balance? Even the best digital cameras struggle with consistently reproducing accurate color. Images shot with incorrect white balance may have unnatural looking red, yellow or blue tints that are time consuming and difficult to correct.To help photographers cope with this problem, digital camera manufacturers have designed their cameras with multiple white balance functions, including Custom White Balance, Automatic White Balance (AWB), and factory Preset color temperature settings for Sun, Shade, Tungsten, Fluorescent, Flash, and Cloudy. When shooting, photographers must select one of the camera's fixed white balance settings to apply in-camera, or to apply later in post processing if using the RAW file format.  Unfortunately, Auto White Balance (AWB) often produces maddeningly inconsistent color results, and the color temperatures assigned to the camera's Preset white balance settings often do not reflect real world lighting conditions, causing a color-cast.  Using the Custom White Balance function remains the most reliable way to consistently reproduce accurate, balanced color in digital cameras. The custom white balance function eliminates the inconsistencies of AWB and the gross generality of factory Preset color temperatures because it allows the user to calibrate the camera to an exact color temperature at image capture. The custom white balance procedure requires a neutral reference like the ExpoDisc to measure the color of light accurately.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Too Warm
  

*by A***B on Reviewed in the United States on March 15, 2013*

This is so easy to use! I got the 77m so I could put it over my small lenses and only needed one. I use it with my Nikon D800 and it makes my photos a bit too warm for me. I am going to try the neutral to see if I like that better.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    The disk works great, but the seller is less stellar.
  

*by S***Y on Reviewed in the United States on April 29, 2013*

The disk works great.The Seller described it: "like new".  But the disk has many small scratches on it from being placed onto the smaller lenses.  This was not described by the seller.  In fact another seller had a "like new" disk for similar price, with a description of one scratch, so I chose this seller which simply did not describe the many scratches the disk has.Anyway, I gave 5 stars to reflect well on the product.  The product still works good with the many small scratches.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good value, durable product
  

*by T***M on Reviewed in the United States on January 30, 2010*

I bought this to go with my Canon EOS 30D.  Canon DSLRs seem to have trouble generally with white balance, and for me the Expodisc seems to clear up this trouble easily.There is only one glitch: You have to take the white balance test shot (with the Expodisc attached to the front of the camera lens) at the location where your subject will be, and with the camera lens pointed toward the light source.  This might be a little more trouble than having the subject hold a grey card for you to shoot.Ken Rockwell (on his website) recommends the warm balance filter because of his own preferences, and I agree.  A warm filter is better when shooting nature and people, in my opinion, since it brings up the reds a little bit.  Expodisc did not over-do the warming either; a little bit is just fine!The Expodisc itself is quite well-built, and the spring-balls around the periphery let you snap it on the front of the lens (with or without additional filters attached) quickly without fiddling with threading, as you would do with any filter for example.  This is very convenient!The optical surfaces are plastic, but I think performance will not suffer as the Expodisc ages and gets scratched and dinged up, since the pigments appear to permeate the entire filter plate.  A diffuser in front also does not worry me, since the curved parts of it are inside, where they cannot accumulate dust.It comes with a neck-strap, making it easy to keep it available while you are shooting.  Also, a beltpack case is provided, which can accomodate the Expodisc and another filter of your choice.I look forward to using this with my circular polarizer filter, because the Expodisc will fix the white balance shift introduced by the circular polarizer (sort of a "coldness"), while preserving the advantages such as cloud and sky visibility and reduction of glare.
