Product Description

Size Name: 77mm

Product Description

ExpoDisc, the original white balance filter gets even better. Set white balance, meter for exposure and dust map your sensor with the only calibrated and certified 18% transmission incident light metering filter

Whether shooting in RAW or JPEG, photographers using ExpoDisc to white balance their images save valuable time in photo editing software. 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

The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera's custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture colour adjustments.

The ExpoDisc is not just for white balance, though. The precision calibration and uniformity of the ExpoDisc means that it can also be used to meter for an 18% incident exposure and to produce a dust map of the image sensor.

To meter for an 18% exposure, stand at the subject's position and aim the camera back towards the intended shooting position. Use the camera's meter as seen through the viewfinder to adjust the aperture, shutter speed, or ISO until a proper exposure is indicated. It's also possible to make exposure adjustments based upon the position of the histogram spike on an ExpoDisc test shot. Simply adjust the aperture, shutter speed, or ISO until the spike is centred.

I saw a review comparing this to a cheap Chinese one and the results are not surprising.
I think if you use a DSLR and you are wanting to take your pics to the next level, this is a must.
If like me you ever used a light meter, this is basically how this works....
Remember the inver cone light meters? incident and reflected readings?
Cameras all take reflected light meter readings which is why they don't always work well, the old analogy of a white wedding dress in a white backdrop or the groom in black against the dark interior of the church, difficult to meter, incident readings are taken from the subject toward the camera, its the light coming to the subject and is the most accurate way of taking a reading.
So you place the disc over your lens and take a reading looking toward where your camera will be. Thats an incident reading.
The WB issue is also a must for digital users. OK so your not going to use it all the time, but those pics you want to be impressive, keepers, you will benefit from this. ie, sunsets if you ever took any sunsets and were disappointed at the result, the colours will not be as strong, why? because auto WB will try to rectify the light which is approaching the red band of the spectrum and correct it. Using the disc will give a setting for the true WB at the scene, the colours in the sky should then show up as you saw them, also use the disc at that time to take an exposure reading, as, that is also something difficult for your camera to expose for.
I have tested this under some fluorescent lights and noticed my 60D gave a magenta cast in auto WB with the disc I didnt, I got pure white, the shot had a whiteboard in it.

very good at what it does ,ie give you a neutral white balance, not always the most pleasing effect however ,which is why we take photos during the golden hour ,it works very well far better than a grey card or white card, you will struggle with on camera flash unless you can bounce the flash off a wall and have it come back at you as it reads as an incident meter would by pointing it at the main light source . Fantastic for weddings etc when you need white balance spot on.Build quality, the first one was better in my opinion being made from an alloy , but they have dropped the price by a third with this plastic one ,is it more accurate well that worked to 18% grey also so cant see how . On the whole a must for all photographers you photos will look a lot better out of the camera especially if you shoot in jpeg .Raw well we can change the white balance post production but its great to start right .if they went back to the metal version then it would get 5 stars .

This is a brilliant piece of kit it really works and is simple to use.
I photograph a lot of product shots using static lighting and this is ideal for setting the correct lighting exposure.
I also used it in a friends studio using flash and again perfect lighting.
It is so easy to use in daylight and sets the correct exposure.
Also use it when videoing especially to get equal settings over vary many different scenes.

Definitely recommend it.

The best white balance adjuster that I have ever used! I thought the auto wb is correct. Not, very not.

Arrived quickly and in good condition. This is the best bit of kit that I have bought in the whole of 2014. Has simplified and sped up getting correct white balance on the studio and is good for using on location too.

For a while I have not been happy with the colour balance results from my Nikon D7100. I use a 10-20 Sigma most of the time so when I do manual (PRE) white balance it can take a number of sources and a single source bounced off a number of different coloured objects.

To cut a long story short the very first shot had a true sky for the very first time and the rest of the image was great too.
You will need to think about where the camera is pointing and this needs thought. BUT nearly every shot is better than pre setting!

Its like a new camera and I am stunned by what I am getting. Landscapes, artificial light, mixed light massive improvements.
